ABSTRACT

Abstract The present study aimed to determine the effect of different levels of protein on the growth, body composition, amino acid profile and serology of Channa marulius fingerlings. The experiment was conducted in ten happas installed in earthen ponds, each stocked with 10 fishes for 90 days. Four commercial fish feeds having 25%, 30%, 32% and 40% crude protein (CP) levels were fed to fish at 3% of their wet body weight three times a day. The results of the study revealed that highest weight gain, feed conversion ratio and survival rate were observed in 30% protein feed. Meanwhile, moisture content was higher in fish fed with 30% CP feed while highest crude protein was recorded in 40% CP fed fish. Lowest fat content was observed in 32% CP feed. Amino acid profile of fish revealed better results in 30% CP feed. Total protein, glucose and globulin were also highest in fish feeding 30% CP feed, while albumin was highest in 40% CP feed. It is concluded that 30% CP feed showed better results in terms of growth, amino acid profile and serological parameters without effecting fish body composition.


Resumo O presente estudo teve como objetivo determinar o efeito de diferentes níveis de proteína sobre o crescimento, composição corporal, perfil de aminoácidos e sorologia de alevinos de Channa marulius. O experimento foi conduzido em dez happas instalados em tanques de terra, cada um abastecido com 10 peixes, por 90 dias. Quatro alimentos para peixes comerciais com níveis de 25%, 30%, 32% e 40% de proteína bruta (PB) foram dados aos peixes com 3% de seu peso corporal úmido três vezes ao dia. Os resultados do estudo revelaram que maior ganho de peso, taxa de conversão alimentar e taxa de sobrevivência foram observados em 30% de proteína alimentar. Enquanto isso, o conteúdo de umidade foi maior em peixes alimentados com 30% de PB, enquanto a proteína bruta mais alta foi registrada em peixes alimentados com 40% de PB. O menor conteúdo de gordura foi observado em rações com 32% de PB. O perfil de aminoácidos dos peixes revelou melhores resultados na ração com 30% de PB. Proteína total, glicose e globulina também foram maiores em peixes alimentados com ração com 30% de PB, enquanto a albumina foi mais alta com 40% de PB. Conclui-se que a ração com 30% de PB apresentou melhores resultados em termos de crescimento, perfil de aminoácidos e parâmetros sorológicos sem afetar a composição corporal dos peixes.

ABSTRACT

Abstract We have evaluated the effects of different fish feeds on the body composition, growth, and enzyme activities of Labeo rohita (Rohu). In total, 240 fishes between the average weights of 24.77±2.15g were studied. The treatments were applied in a completely randomized design, with 4 treatments of 60 fishes each. Treatments consisted of four different fish feeds [Oryza (T1), AMG (T2), Aqua (T3), and Supreme (T4)]. Body composition, growth performance, and enzyme activities were evaluated. There was a significant variation in performance of fishes fed with different type of feed; as fishes having Oryza feed showed the highest weight gain, specific growth rate (SGR), and best feed conversion ratio (FCR) as compared to other groups that were considered to be significant (P ≤ 0.05). High net weight gain was obtained in T4 when compared with T2 and T3. FCR value of T4 was less than T1 but higher than T2, T3 and T2, which showed the lowest values. The specific growth rate was recorded as average in T4, but T2 led a high SGR than T3. Similarly, crude protein level and digestive enzymes activity was recorded significantly highest in fed with Oryza (T1) as compared to AMG (T2), Aqua (T3), and Supreme (T4). Water quality parameters were recorded significant in all treatments except pH and DO of treatment (T1), significantly different from other treatments. It was concluded that Rohu (Labeo rohita) could show a promising growth rate and protease enzyme activity when fed with the Oryza feed of 25% protein.


Resumo Avaliamos os efeitos de diferentes alimentos para peixes em relação à composição corporal, crescimento e atividades enzimáticas de Labeo rohita (Rohu). No total, foram estudados 240 peixes com pesos médios de 24,77 ± 2,15 g. Os tratamentos foram aplicados em delineamento inteiramente casualizado, com quatro tratamentos de 60 peixes cada. Os tratamentos consistiram em quatro alimentos diferentes para peixes: Oryza (T1), AMG (T2), Aqua (T3) e Supreme (T4). Foram avaliados a composição corporal, o desempenho de crescimento e as atividades enzimáticas. Houve uma variação significativa no desempenho dos peixes alimentados com diferentes tipos de ração. Peixes com alimentação Oryza apresentaram maior ganho de peso, taxa de crescimento específico (SGR) e melhor taxa de conversão alimentar (FCR) em comparação com outros grupos que foram considerados significativos (P ≤ 0,05). Elevado ganho de peso líquido foi obtido em T4 quando comparado com T2 e T3. O valor da FCR de T4 foi menor que T1, mas maior que T2 e T3, que apresentaram os menores valores. A taxa de crescimento específico foi registrada como média em T4, mas T2 teve uma SGR alta do que T3. Da mesma forma, o nível de proteína bruta e a atividade das enzimas digestivas foram registrados significativamente mais altos nos peixes alimentados com Oryza (T1) em comparação com AMG (T2), Aqua (T3) e Supreme (T4). Os parâmetros de qualidade da água foram registrados como significativos em todos os tratamentos, exceto pH e OD do tratamento (T1), significativamente diferente dos demais tratamentos. Concluiu-se que Rohu (Labeo rohita) pode apresentar uma taxa de crescimento promissora e atividade da enzima protease quando alimentado com Oryza de 25% de proteína.

ABSTRACT

Abstract The growth of aquaculture sector is strongly dependent upon the continuous supply of inexpensive fish feed with balanced nutritional profile. However, fish meal (FM) is unable to satisfy this demand due to its scarce supply and high cost. In order to test the potential of cottonseed meal (CSM) as a fish meal replacer, a feeding trial of 12 weeks was conducted to check growth performance and proximate composition of Labeo rohita fingerlings. The protein ration of the test feed was satisfied by replacing FM with CSM at 0, 25, 50 and 75%. Sixteen test diets viz., TD1 (control), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 and TD16 were supplemented with citric acid (CA; 0 and 2.5%) and phytase (PHY; 0 and 750 FTU/kg) in a completely randomized design with 3×3 factorial arrangement. The highest weight gain (11.03g), weight gain% (249.21%), specific growth rate (1.39) and best feed conversion ratio (1.20) were recorded by fish fed with TD12. Furthermore, the same level increased the crude protein (59.26%) and fat (16.04%) being significantly different (p<0.05) than that of control. Conclusively, the addition of acidified phytase (CA; 2.5%, PHY; 750 FTU/kg) in TD12 (CSM=50%) led to the improved growth and proximate composition of L. rohita fingerlings.


Resumo O crescimento do setor de aquicultura é fortemente dependente do fornecimento contínuo de rações baratas para peixes com perfil nutricional equilibrado. Porém, a farinha de peixe (FM) não consegue atender a essa demanda devido à sua escassa oferta e alto custo. Com o objetivo de testar o potencial da farinha de semente de canola (MSC) como substituto da farinha de peixe, um ensaio alimentar de 12 semanas foi conduzido para verificar o desempenho de crescimento e a composição centesimal de alevinos de Labeo rohita. A ração de proteína da ração teste foi satisfeita substituindo FM por CSM em 0, 25, 50 e 75%. Dezesseis dietas de teste, viz., TD1 (controle), TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, TD10, TD11, TD12, TD13, TD14, TD15 e TD16 foram suplementadas com ácido cítrico (CA; 0 e 2,5%) e fitase (PHY; 0 e 750 FTU / kg) em um delineamento inteiramente casualizado com arranjo fatorial 3 × 3. O maior ganho de peso (11,03g), % de ganho de peso (249,21%), taxa de crescimento específico (1,39) e melhor taxa de conversão alimentar (1,20) foram registrados por peixes alimentados com TD12. Além disso, o mesmo nível aumentou a proteína bruta (59,26%) e a gordura (16,04%), sendo significativamente diferente (p <0,05) do controle. Conclusivamente, a adição de fitase acidificada (CA; 2,5%, PHY; 750 FTU / kg) em TD12 (CSM = 50%) levou a um melhor crescimento e composição próxima de alevinos de L. rohita.

ABSTRACT

ABSTRACT Background: The nutritional status of patients with colorectal cancer (CRC) impacts on treatment response and morbidity. An effective evaluation of the body composition includes the measurements of fat and visceral fat-free mass and is currently being used in the diagnosis of the nutritional status. The better understanding regarding nutritional tools for body composition evaluation in CRC patients may impact on the outcome. Methods: Systematic review conducted according to Preferred Items of Reports for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A literature search was performed using the BVS (LILACS), PubMed, Embase, Cochrane, Scopus, and Web of Science databases. Results: For the initial search, 97 studies were selected and 51 duplicate manuscripts were excluded. Thus, 46 were reviewed and seven studies included with a total of 4,549 patients. Among them were one clinical trial, one prospective study (cohort), two retrospective cohort and two cross-sectional studies. All studies included body composition evaluated by computed tomography, one with bioelectrical impedance, one with handgrip strength, and two employed mid-arm muscle circumference and body mass index. Conclusion: Current evidence suggests that computed tomography has better accuracy in the diagnosis of sarcopenia, visceral fat, and myopenia among individuals with CRC. Further studies are needed to identify cutoff points for these changes aggravated by CRC.

ABSTRACT

Abstract Background: This study aimed to evaluate the relationship between quadriceps muscle thickness and functional performance on the 60s sit-to-stand test (60s-STS), the six-minute walk test (6MWT), and handgrip strength in non-dialytic stage 4 and 5 chronic kidney disease (CKD) patients. Methods: This was a cross-sectional study that evaluated 40 CKD patients aged between 30-70 years. Participants were submitted to an assessment that included quadriceps muscle thickness evaluated by a portable ultrasound. Functional performance tests included the 60s-STS, distance walked in the 6MWT, and handgrip strength. Also, body composition evaluated using electrical bioimpedance analysis and physical activity level through the short version of International Physical Activity were measured. Multiple linear regression was used to investigate the relationship between the quadriceps thickness and functional performance. Results: Quadriceps muscle thickness was correlated to 60s-STS (R2 = 43.6%; 95% CI = 0.022 - 0.665; β = 0.34; p = 0.037). Also, a moderate correlation between this muscle thickness and appendicular skeletal muscle (ALM) was found in CKD patients (r = 0.603, p <0.001). No relationship was found between quadriceps muscle thickness with the 6MWT and handgrip strength. Conclusion: Quadriceps muscle thickness is associated to 60s-STS, thus our results demonstrate the repercussions of the disease on the musculoskeletal system.


Resumo Antecedentes: Este estudo teve como objetivo avaliar a relação entre espessura muscular do quadríceps e desempenho funcional no teste sit-to-stand de 60s (STS-60s), no teste de caminhada de seis minutos (TC6M), e na força de preensão manual em pacientes não dialíticos com doença renal crônica (DRC) estágios 4 e 5. Métodos: Este foi um estudo transversal que avaliou 40 pacientes com DRC com idades entre 30-70 anos. Os participantes foram submetidos a uma avaliação que incluiu a espessura muscular do quadríceps avaliada por um ultrassom portátil. Os testes de desempenho funcional incluíram o STS-60s, a distância percorrida no TC6M e a força de preensão manual. Além disso, foram medidos a composição corporal, avaliada usando a análise de bioimpedância elétrica e o nível de atividade física por meio da versão curta do International Physical Activity. A regressão linear múltipla foi usada para investigar a relação entre a espessura do quadríceps e o desempenho funcional. Resultados: A espessura muscular do quadríceps foi correlacionada com o STS-60s (R2 = 43,6%; IC 95% = 0,022 - 0,665; β = 0,34; p = 0,037). Também foi encontrada uma correlação moderada entre esta espessura muscular e a massa muscular esquelética apendicular (MEA) em pacientes com DRC. (r = 0,603, p <0,001). Nenhuma relação foi encontrada entre a espessura muscular do quadríceps com o TC6M e a força de preensão manual. Conclusão: A espessura muscular do quadríceps está associada ao STS-60s, assim nossos resultados demonstram as repercussões da doença sobre o sistema músculo-esquelético.

ABSTRACT

Abstract Objective: This study had the purpose investigate the physical activity (PA) and sedentary time profile of children with cerebral palsy and its association with body composition. Methods: A cross-sectional study evaluated 53 children, between 2 and 10 years old, enrolled in three health services Recife-city, northeast of Brazil. Sedentary and PA were measured for a week using the ActiGraph GTX3 accelerometer. Body composition was assessed by anthropometry and an electrical bioimpedance device. Results: Time on PA was one hour longer among the mild/moderate CP compared to severe ones, but, sedentary time is similar. Dyskinetic children spent more time in PA, but also in sedentary activities (15.5 hours a day) than spastic ones (12.8). Stunting occurred in 15 (30%) of the sample, all children with stunting had severe impairment. Underweight occurred in 25% of the severe group and 11.8% in the mild/moderate group. Overweight affected 3% of the sample; no overweight children were in the severe group. Body fat% was inversely related to time spent in moderate to vigorous PA. Conclusions: Children with CP spend more than a half of their daily time in sedentary activity. In contrast, children with mild to moderate CP spent twice as much time in moderate to vigorous PA and had a tendency (p = 0.07) to spend 50% more time in light PA. Moreover, time spent on moderate to vigorous activity was inversely related to fat mass.

ABSTRACT

SUMMARY: The purpose of this study was to assess the correlation between the body composition, multiple repeated sprint ability (MRSAB) test, and vertical jump performance. Fifteen voluntary elite Turkish badminton players participated in the study. The MRSAB test consisted of 2 repetitions of 4 movements (4x3m) separated by 30 seconds of passive recovery. The best time (BT), meantime (MT), total time (TT), and fatigue index (FI) were measured. Body composition was evaluated through dual-energy X-ray absorptiometry (DEXA). Squat jump (SJ) test for explosive power and countermovement jump (CMJ) test for elastic power were used. The main findings were that there was a significant correlation between MRSAB MT and TT with lean body mass, lean arm mass, and trunk lean mass (kg) of male badminton players. However, no significant correlation was observed among MRSAB MT, BT, and TT with another total/regional body composition of female badminton players (p>0.05). Moreover, the results of male badminton players showed that there was a significant negative correlation between FI and percentage ofbody fat (%BF), percentage of leg fat (%LF), percentage of trunk fat (%TF), and trunk mass. In addition, there was a significant negative correlation between FI with %BF, body fat mass kg, percentage of arm fat (%AF), arm fat mass, and %LF of female badminton players. It was also found in the study that there was a significant correlation between SJ and %LF; CMJ and %BF, body fat mass kg, %AF, %LF and leg fat mass kg. However, no significant correlation was observed among CMJ and SJ with other total/regional body compositions of male badminton players (p>0,05). Finally, changes in body composition are important issues for the physical performance level of badminton players as regional excess body fat may cause deterioration, especially in repeated-sprint ability and jumping performance.


RESUMEN: El propósito de este estudio fue evaluar la correlación entre la composición corporal, la prueba de capacidad de sprint repetido (MRSAB) y el rendimiento del salto vertical. Quince jugadores voluntarios de bádminton turcos de élite participaron en el estudio. El test MRSAB consistió en 2 repeticiones de 4 movimientos (4x3m) separados por 30 segundos de recuperación pasiva. Se midieron el mejor tiempo (BT), el tiempo medio (MT), el tiempo total (TT) y el índice de fatiga (FI). La composición corporal se evaluó mediante absorciometría de rayos X de energía dual (DEXA). Se utilizó la prueba de salto desde la sentadilla (SJ) para la potencia explosiva y la prueba de salto con contramovimiento (CMJ) para la potencia elástica. Los principales hallazgos fueron una correlación significativa entre MRSAB MT y TT con la masa corporal magra, la masa magra del brazo y la masa magra del tronco (kg) de los jugadores de bádminton hombres. Sin embargo, no se observó una correlación significativa entre MRSAB MT, BT y TT con otra composición corporal total/regional de jugadoras de bádminton (p>0,05). Además, los resultados de los jugadores hombres de bádminton mostraron que había una correlación negativa significativa entre FI y el porcentaje de grasa corporal (% BF), porcentaje de grasa en las piernas (% LF), porcentaje de grasa en el tronco (% TF) y masa del tronco. Además, hubo una correlación negativa significativa entre FI con %GC, masa de grasa corporal en kg, porcentaje de grasa en el brazo (%AF), masa de grasa en el brazo y %LF de las jugadoras de bádminton. También se descubrió en el estudio que había una correlación significativa entre SJ y %LF; CMJ y %BF, masa grasa corporal kg, %AF, %LF y masa grasa de piernas kg. Sin embargo, no se observó una correlación significativa entre CMJ y SJ con otras composiciones corporales totales/regionales de los hombres jugadores de bádminton (p>0,05). Finalmente, los cambios en la composición corporal son cuestiones importantes para el nivel de rendimiento físico de los jugadores de bádminton, debido a que el exceso de grasa corporal regional, puede causar un deterioro, especialmente en la capacidad de repetir sprints y en el rendimiento de los saltos.

ABSTRACT

Introduction: Nutritional deficiencies, hormonal changes and severe weight loss after Roux-en-Y Gastric Bypass (RYGB) can promote changes in bone metabolism which may lead to a reduction in bone mineral density (BMD). Objective: to investigate the prevalence of osteopenia/osteoporosis and factors associated with BMD in pre-menopausal women who underwent RYGB. Methodology: a cross-sectional study conducted with secondary data of patients followed-up in a specialized center for obesity treatment. Variables studied: biochemical and anthropometric data, body composition by multifrequency bioimpedance and BMD of the lumbar spine (LS), total femur (TF) and femur neck (FN) by dual-energy X-ray absorptiometry. For statistical analysis, the SPSS® software and a 5% significance level were utilized. Results: seventy-two (72) pre-menopausal women were evaluated. Mean age, BMI and mean post-surgery time was 38.7±6.5 years, 25.8±2.5 kg/m² and 13.1±1.7 months, respectively. The prevalence of osteopenia in at least one of the densitometry sites was 13.9%, with LS being the most frequent site. A lower LS BMD was associated with greater weight loss, higher percentage of body fat before surgery and lower post-surgery serum vitamin D levels. There was a positive correlation between skeletal muscle mass index adjusted for height in the pre-surgery period and LS BMD (r=0.361; p=0.010) and TF (r=0.404; p=0.004). Conclusion: a relevant prevalence of osteopenia was detected in pre-menopausal women after RYGB, mainly in the LS.


Introdução: o Bypass Gástrico em Y de Roux (BPGYR) pode promover mudanças no metabolismo ósseo decorrentes de deficiências nutricionais, alterações hormonais e perda severa de peso, podendo acarretar redução da Densidade Mineral Óssea (DMO). Objetivo: investigar a prevalência de osteopenia/osteoporose e fatores associados à DMO em mulheres pré-menopausadas submetidas à BPGYR. Metodologia: estudo transversal com dados secundários de pacientes acompanhadas em um serviço especializado no tratamento da obesidade. Variáveis estudadas: dados bioquímicos e antropométricos, composição corporal por bioimpedância multifrequencial e DMO de coluna lombar (CL), fêmur total (FT) e colo do fêmur (CF) por Absorciometria por Dupla Emissão de Raios X. Para análise estatística foi utilizado o programa SPSS®, com o nível de significância de 5%. Resultados: foram avaliadas 72 mulheres pré-menopausadas, com média de idade e de IMC de 38,7±6,5 anos e 25,8±2,5 kg/m², respectivamente, e tempo médio de pós-operatório de 13,1±1,7 meses. A prevalência de osteopenia em pelo menos um dos sítios densitométricos foi de 13,9%, sendo a CL o sítio mais frequente. Uma menor DMO na CL se associou a maior perda de peso, maior percentual de massa gorda antes da cirurgia e níveis séricos menores de vitamina D pós-operatória. Observou-se correlação positiva entre o índice de massa muscular esquelética ajustada pela altura no pré-operatório e a DMO da CL (r=0,361; p=0,010) e do FT (r=0,404; p= 0,004). Conclusão: detectou-se prevalência relevante de osteopenia em mulheres pré-menopausadas após BPGYR, principalmente na CL.

ABSTRACT

SUMMARY OBJECTIVE: This study aimed to explore the correlation between different body components and bone mineral density in healthy adults. METHODS: A total of 306 non-manual subjects, 161 males and 145 females, were selected from the physical examination center of our hospital from June to September 2019. They were divided into control group, overweight group, and obese group according to body mass index. The muscle mass and fat mass, body fat content, trunk fat mass, upper limb and thigh fat mass, bone density of femoral neck and lumbar vertebra, and bone mineral salt content of the whole body were measured by dual-energy X-ray absorptiometry. RESULTS: Body mass index, systolic blood pressure, diastolic blood pressure, femoral neck bone mineral density, bone mineral salt content, fat mass, muscle mass, upper limb fat mass, thigh fat mass, and trunk fat mass in the overweight group and obese group were all higher than those in the control group (P<0.05). The fat mass, muscle mass, upper limb fat mass, and trunk fat mass were positively correlated with the femoral neck bone mineral density, total lumbar vertebra bone mineral density, and bone mineral salt content (P<0.05). In addition, thigh fat mass was positively correlated with femoral neck bone mineral density and total lumbar spine bone mineral density, whereas body fat content was negatively correlated with bone mineral salt content. CONCLUSION: Body composition was related to bone mineral density and bone mineral salt content, and the correlation between different body composition indexes, and bone mineral density, and bone mineral salt content was different.

ABSTRACT

SUMMARY: Previous evidence indicates that body fat can distinguish Brazilian jiu-jitsu (BJJ) athletes according to the competitive level. However, propositions of cut-off points for establishing classifications of body fat percentage for combat sports athletes and, specifically, for BJJ athletes are still incipient in the literature. In this sense, the main aim of the present study was to establish a normative table for the classification of body fat percentage in BJJ athletes. As a secondary aim, athletes were compared according to competitive level. Ninety male BJJ athletes (aged: 29.0 ± 8.2 years; practice time: 6.0 ± 2.1 years; body mass: 82.1 ± 12.7 kg; height: 175.9 ± 6.5 cm; fat mass: 16.0 ± 8.9 kg; bone mineral content: 3.7 ± 0.6 kg; muscle mass: 37.9 ± 5.4 kg; body fat percentage: 17.3 ± 6.8 %; basal metabolic rate: 1811.4 ± 193.4 kcal) from different competitive levels: state (n= 42), national (n= 26) and international (n= 22) took part in this study. All athletes had their body composition measured via tetrapolar bioelectrical impedance. Percentiles p10, p25, p50, p75, and p90 were used to establish the classification. As a result, the following classification was obtained: <7.7 % (very low); ≥7.7-11.5 % (low); 11.6-17.0 % (medium); 17.1-24.0 % (high) and ≥24.1 % (very high). State-level athletes had a higher fat percentage than national and international-level athletes (p<0.05). The proposed cut-off points can help professionals responsible for sports training and nutritional prescription in monitoring the body fat of BJJ athletes.


RESUMEN: La grasa corporal puede distinguir a los atletas de jiu-jitsu brasileño (BJJ) según el nivel competitivo. Sin embargo, las propuestas de puntos de corte para establecer clasificaciones de porcentaje de grasa corporal para deportistas de deportes de combate y, específicamente, para deportistas de BJJ son aún incipientes en la literatura. En este sentido, el objetivo principal del presente estudio fue establecer una tabla normativa para la clasificación del porcentaje de grasa corporal en atletas de BJJ. Secundariamente, comparar a los deportistas según el nivel competitivo. Participaron noventa atletas masculinos de BJJ (edad: 29,0 ± 8,2 años; tiempo de práctica: 6,0 ± 2,1 años; masa corporal: 82,1 ± 12,7 kg; estatura: 175,9 ± 6,5 cm; masa adiposa: 16,0 ± 8,9 kg; contenido mineral óseo: 3,7 ± 0,6 kg; masa muscular: 37,9 ± 5,4 kg; porcentaje de grasa corporal: 17,3 ± 6,8 %; tasa metabólica basal: 1811,4 ± 193,4 kcal) de diferentes niveles competitivos: estatal (n= 42), nacional (n= 26) e internacional (n= 22). Se evaluó la composición corporal a través de bioimpedancia tetrapolar. Para establecer la clasificación se utilizaron los percentiles p10, p25, p50, p75 y p90. Como resultado se obtuvo la siguiente clasificación: <7,7 % (muy bajo); ≥7,7-11,5 % (bajo); 11,6-17,0 % (medio); 17,1-24,0 % (alto) y ≥24,1 % (muy alto). Los atletas de nivel estatal tenían un porcentaje de grasa corporal más alto respecto a los atletas de nivel nacional e internacional (p <0.05). Los puntos de corte propuestos pueden ser útiles para monitorizar la grasa corporal de los atletas de BJJ.

ABSTRACT

SUMMARY: This study aims to determine the possible differences anthropometric characteristics and body composition profiles of elite taekwondo players with or without medals in European championships. Twenty-one black-belt elite taekwondo athletes (17.4±1.2 years) from the Turkish national team were divided into two groups, namely, medalists (MEC; n =11) and non-medalists (NmEC; n=10) in European championships. Twenty-eight anthropometric measurements including height, body mass, length, circumferences, breadth, and skinfolds were taken following the standard techniques proposed by the International Society for the Advancement of Kinanthropometry (ISAK). Body composition variables were evaluated by using skinfold thickness measurements. Results demonstrated that anthropometric and body composition, variables did not differ significantly between medalist and non-medalist taekwondo players (p>0.01). Our athletes have a low percentage of body fat and high muscle mass profile. Medalist and non-medalist elite Turkish taekwondo players in the European championships do not differ in terms of anthropometric and body composition components. They have a similar body composition profile suitable for taekwondo players and within acceptable healthy ranges. The present study assists coaches in the formulation of appropriate training programs aiming the development for managing the body composition status of players, which will be associated with high-level performance in taekwondo. Future studies should include body composition and somatotype profile inspection throughout the weight categories.


RESUMEN: Este estudio tuvo como objetivo determinar las posibles diferencias antropométricas y perfiles de composición corporal de los peleadores de taekwondo de élite, con o sin medallas en campeonatos europeos. Veintiún atletas de taekwondo de élite de cinturón negro (17,4 ± 1,2 años) del equipo nacional turco se dividieron en dos grupos, medallistas (MEC; n = 11) y no medallistas (NmEC; n = 10). Se tomaron veintiocho medidas antropométricas incluyendo altura, masa corporal, longitud, circunferencias, ancho y pliegues cutáneos siguiendo las técnicas estándar sugeridas por la Sociedad Internacional para el Avance de la Cineantropometría (ISAK). Las variables de composición corporal se evaluaron mediante mediciones del grosor de los pliegues cutáneos. Los resultados demostraron que las variables antropométricas y de composición corporal no difirieron significativamente entre los jugadores de taekwondo medallistas y no medallistas (p> 0,01). Nuestros deportistas tienen un bajo porcentaje de grasa corporal y un alto perfil de masa muscular. Los medallistas y no medallistas de taekwondo turcos de élite en los campeonatos europeos no difieren en términos de components antropométricos y de composición corporal. Tienen un perfil de composición corporal similar adecuado para peleadores de taekwondo y dentro de rangos saludables aceptables. El presente estudio ayuda a los entrenadores en la formulación de programas de entrenamiento apropiados que apunten al desarrollo para manejar el estado de la composición corporal de los peleadores, lo que se asociará con un rendimiento de alto nivel en taekwondo. Los estudios futuros deben incluir la inspección de la composición corporal y el perfil del somatotipo en todas las categorías de peso.

ABSTRACT

Abstract BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) has become a public health problem worldwide. Neck circumference (NC) is a simple anthropometric adiposity parameter that has been correlated with cardiometabolic disorders like NAFLD. OBJECTIVES: To investigate the association between NC and NAFLD, considering their obesity-modifying effect, among participants from the Longitudinal Study of Adult Health (ELSA-Brasil) baseline study. DESIGN AND SETTINGS: Cross-sectional study at the ELSA-Brasil centers of six public research institutions. METHODS: This analysis was conducted on 5,187 women and 4,270 men of mean age 51.8 (± 9.2) years. Anthropometric indexes (NC, waist circumference [WC] and body mass index [BMI]), biochemical and clinical parameters (diabetes, hypertension and dyslipidemia) and hepatic ultrasound were measured. The association between NC and NAFLD was estimated using multinomial logistic regression, considering potential confounding effects (age, WC, diabetes, hypertension and dyslipidemia). Effect modification was investigated by including the interaction term NC x BMI in the final model. RESULTS: The frequency of NAFLD and mean value of NC were 33.6% and 33.9 (± 2.5) cm in women, and 45.8% and 39.4 (± 2.8) cm in men, respectively. Even after all adjustments, larger NC was associated with a greater chance of moderate/severe NAFLD (1.16; 95% confidence interval [CI] for women; 1.05, 95% CI for men; P < 0.001). Presence of multiplicative interaction between NC and BMI (P < 0.001) was also observed. CONCLUSION: NC was positively associated with NAFLD in both sexes, regardless of traditional adiposity indexes such as BMI and WC. The magnitude of the association was more pronounced among women.

ABSTRACT

ABSTRACT BACKGROUND: Studies that test associations between anthropometric indicators and insulin resistance (IR) need to provide better evidence in the context of the pediatric population (children and adolescents) with human immunodeficiency virus (HIV), as anthropometric indicators present a better explanation of the distribution of body fat. OBJECTIVE: To test the associations between anthropometric indicators and insulin resistance (IR) among children and adolescents diagnosed with HIV. DESIGN AND SETTING: Cross-sectional study on 65 children and adolescents (8-15 years) infected with HIV through vertical transmission conducted at the Joana de Gusmão Children's Hospital, Florianópolis, Brazil. METHODS: The anthropometric indicators measured were the abdominal (ASF), triceps (TSF), subscapular (SSF) and calf (CSF) skinfolds. The relaxed arm (RAC), waist (WC) and neck (NC) circumferences were also measured. Body mass index (BMI) was calculated from the relationship between body mass and height. IR was calculated through the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR). Simple and multiple linear regression analyses were used. RESULTS: After adjustment for covariates (sex, bone age, CD4+ T lymphocytes, CD8+ T lymphocytes, viral load, and physical activity), associations between IR and models with SSF and CSF remained. Each of these explained 20% of IR variability. For females, in the adjusted analyses, direct associations between IR and models with ASF (R² = 0.26) and TSF (R² = 0.31) were observed. CONCLUSIONS: SSF and CSF in males and ASF and TSF in females were associated with IR in HIV-infected children and adolescents.

ABSTRACT

Objective@#To explore the relationship between prepregnancy body mass index, weight gain during pregnancy with preschool obesity and body composition in offspring, so as to provide evidence for gestational weight gain and childhood obesity prevention.@*Methods@#A total of 1 333 preschool children were recruited from 3 kindergartens in Tianjin from September to December 2020. Structured questionnaire was used to collect children s lifestyle information. Height, weight and body fat mass of children were assessed, and body fat percentage (FM%), fat mass index (FMI) and non fat mass index (FFMI) were calculated. Maternal medical records were collected and the mothers were grouped according to their prepregnancy weight status and weight gain during pregnancy. χ 2 test, t test, linear regression model and Logistic regression were used to analyze the differences of obesity and body composition among different groups.@*Results@#The prevalence of overweight and obesity in preschoolers was 12.7% and 7.7%. After adjusting maternal age and delivery, gestational age, gender, age and lifestyle of children, the correlation between maternal pre pregnancy BMI,gestational weight gain with obesity and body composition indexes of children in preschool age was statistically significant ( P <0.05). For mothers with normal weight before pregnancy, excessive weight gain during pregnancy increased risk of high FM% and high FMI in offspring ( OR=1.81, 1.68, P <0.05). There was no significant correlation between maternal weight gain during pregnancy with offspring obesity and body composition among mothers with prepregnant overweight or obesity.@*Conclusion@#Maternal weight status before pregnancy and weight gain during pregnancy are correlated with obesity and body composition in the preschool age of offspring. It is suggested that mothers should maintain appropriate weight status before and during pregnancy.

ABSTRACT

Objective@#To investigate the correlation between fat mass percentage(FM%), fat mass index(FMI), fat free mass index(FFMI), body mass index (BMI) and physical fitness, and to explore the potential value of body composition index in predicting physical exercise level of children and adolescents.@*Methods@#Data came from 2013 revision of National Students Physical Health Standard of Ministry of Education in Beijing. Body composition of 4 069 children and adolescents aged 6-20 years in Beijing was measured by the BIA(inbody 230). FM, FMI, FFMI and BMI were divided into four groups by quartile method. The differences and trends of the four groups were analyzed by graphpad prism 8.0 software.@*Results@#FM% (20.03±10.39) and FMIS [(4.35± 2.84 )kg/m 2] of oys were significantly lower than those of girls, while FFMI [(14.21±4.95)kg/m 2] and BMI [(20.31±4.27) kg/m 2 ] of boys were significantly higher than those of girls( t =-13.36, -7.66, 11.49, 8.16, P <0.01). In boys, with the increase of FM% and FMI, the performance of 50 m, 1 000 m, standing long jump and pull up showed a downward trend; with the increase of FFMI, the performance of 50 m, standing long jump and pull up had an obvious upward trend. In girls, with the increase of FM% and FMI, the 50 m running time was gradually shortened, and the 800 m running time was gradually increasing; High FFMI was associated with higher performance in 50 m running, while no association was observed between FFMI and 800 m running.Four body composition indicators showed no effects on performance of sitting forward flexion and 1 minute sit up.@*Conclusion@#FM%, FMI, FFMI and BMI have a good predictive effect on physical fitness of children and adolescents. Adolescents with higher FFMI, lower FM% and FMI have better muscle burst strength, muscle endurance, flexibility, aerobic ability and anaerobic ability, especially in boys.

ABSTRACT

SUMMARY: In several sports, morphological differences exist when comparing training status. However, these are less known in novel urban sports such as Street Workout (SW). This study compares the morphological characteristics between untrained (novice) and trained (experienced) SW athletes. Thirty-seven male Street workout practitioners from Viña del Mar (Chile) participated. Anthropometric, body composition, and somatotype data were assessed and compared according to the training experience. We found that trained SW athletes had a higher flexed and tensed arm perimeter (+4.4 %, p=0.038), lower hips perimeter (-4.8 %, p=0.041), narrower biiliocristal breadth (-3.2 %, p=0.035), lesser sum of 6 skinfolds (-40.8 %, p<0.001), and a lower endomorphic component (p<0.001) than untrained SW athletes. The proportionality analysis revealed that trained athletes had significantly higher upper body perimeters and lower skinfolds than untrained athletes. In addition, trained participants had higher percentages of the whole-body (+6.5 %, p<0.001) and upper limb muscle mass (+1.1 %; <0.001), and lower fat mass percentage (-7.9 %, p<0.001) and fat mass (-6.9 kg, p<0.001). In conclusion, similar to other sports, morphological differences exist in SW according to the training status, suggesting that morphology is associated with training experience. Further studies using DEXA should corroborate our findings and, in turn, determine the relevance of morphology in SW performance.


RESUMEN: En diversos deportes, existen diferencias morfológicas según la experiencia de entrenamiento. Sin embargo, en nuevos deportes urbanos como el Street Workout (SW) las diferencias son menos conocidas. El objetivo de este estudio es comparar las características morfológicas entre atletas de SW desentrenados (novatos) y entrenados (experimentados). Participaron treinta y siete hombres practicantes de SW en Viña del Mar (Chile). Se recolectaron datos antropométricos, de composición corporal y somatotipo, los cuales se compararon según la experiencia de entrenamiento. Encontramos que los atletas entrenados de SW tienen mayor perímetro de brazo flexionado y contraído (+4,4 %, p=0,038), menor perímetro de caderas (-4,8 %, p=0,041), diámetro biiliocrestideo (- 3,2 %, p=0,035), menor suma de 6 pliegues cutáneos (-40,8 %, p<0,001), y menor componente endomórfico (p<0,001), en comparación a los atletas desentrenados. El análisis de proporcionalidad reveló que los entrenados tienen perímetros de miembro superior más grandes y menores pliegues que los atletas desentrenados. Además, los entrenados tienen porcentajes mayores de masa muscular total (+6,5 %, p<0,001) y miembro superior (+1,1 %; <0,001), mientras que menor porcentaje de masa grasa (-7,9 %, p<0,001) y masa grasa (-6,9 kg, p<0,001). En conclusión, existen diferencias morfológicas en el SW según el nivel de entrenamiento, sugiriendo que la morfología está asociada a la experiencia de entrenamiento. Futuros estudios deberían corroborar nuestros hallazgos utilizando DEXA y, a la vez, determinar la relevancia de la morfología en el rendimiento en el SW.

Métodos Estudo de coorte com idosos (≥65 anos), realizado em 2008-2009 (linha de base) e 2016-2017 (seguimento) em Campinas/SP e Ermelino Matarazzo/SP, Brasil. Foram aferidas medidas de peso corporal, estatura, circunferência da cintura (CC) e do quadril (CQ), usadas para obter os indicadores: índice de massa corporal (IMC), razão cintura-estatura (RCE), razão cintura-quadril (RCQ) e índice de conicidade (Índice C). Os testes T e de Wilcoxon para amostras pareadas foram usados para estimar as diferenças. Resultados Foram analisadas informações de 537 idosos (70,0% mulheres) com idade média de 72,2 anos na linha de base e 80,7 anos no seguimento. Após nove anos, os homens apresentaram reduções significativas do peso corporal, estatura e IMC, e aumento do Índice C. Nas mulheres, observou-se declínio do peso, estatura e IMC, e elevação da CC, CQ, RCE, RCQ e Índice C. Observaram-se variações percentuais de: -3,89% (peso), -0,36% (estatura), -4,18% (IMC) e +2,27% (Índice C) nos homens; -2,95% (peso), -0,65% (estatura), -0,73% (IMC), +3,33% (CC), +1,59% (CQ), +3,45% (RCE), +2,27% (RCQ) e +4,76% (Índice C) nas mulheres. O excesso de peso associou-se com maiores chances de estabilidade e de novos casos de menor VM no seguimento. Conclusão Foram identificadas mudanças no peso, estatura, IMC, nos indicadores de obesidade abdominal, especialmente nas mulheres, e associação entre excesso de peso e menor VM.


Abstract Objective To characterize changes in anthropometric indicators in older adults and investigate whether being overweight was associated with lower gait speed (GS), based on measurements taken at an interval of nine years. Methods Cohort study with older adults (≥65 years), conducted in 2008-2009 (baseline) and 2016-2017 (follow-up) in the city of Campinas/SP and in Ermelino Matarazzo/SP, Brazil. Body weight, height, waist circumference (WC) and hip (HC) measurements were taken and used to determine the following indicators: body mass index (BMI), waist-to-height ratio (WHtR), waist-to-hip ratio (WHR) and conicity index (C index). The T and Wilcoxon tests for paired samples were used to estimate the differences. Results Information from 537 older adults (70.0% women) with a mean age of 72.2 years at baseline and 80.7 years at follow-up were analyzed. After nine years, the men showed significant decreases in weight, height and BMI, and an increase in the C index. In women, decreases in weight, height and BMI, and increases in WC, HC, WHtR, WHR and C index were observed. The percentage variations observed were: -3.89% (weight), -0.36% (height), -4.18% (BMI) and +2.27% (C index) among men; -2.95% (weight), -0.65% (height), -0.73% (BMI), +3.33% (WC), +1.59% (HC), +3.45% (WHtR), +2.27% (WHR) and +4.76% (C-Index) among women. Being overweight was associated with greater odds ratio of stability and new cases of lower GS at follow-up. Conclusion Changes were identified in weight, height, BMI, and indicators of abdominal obesity, especially in women, together with an association between being overweight and lower GS.

ABSTRACT

Objective: To assess the effects of order of resistance training (RT) and high-intensity interval training (HIIT) on functional capacity, blood pressure, and body composition in middle-aged and older women. Methods: Twenty-two participants were randomly assigned to one of two groups: RT followed by HIIT (RT-HIIT, n = 10, mean age 64.5 ± 7.9 years) or HIIT followed by RT (HIIT-RT, n = 10, mean age 59.32 ± 4.44 years). Both groups trained twice a week for 8 weeks. RT was composed of 7 exercises for the upper and lower body. HIIT was composed of alternate pairings of high-intensity (> 85% of maximum heart rate [MHR]) and moderate-intensity (60% MHR) running. Results: A time effect was found for upper-body muscle endurance (HIIT-RT = +9.43%; RT-HIIT = +6.16%), agility and dynamic balance (HIIT-RT = -5.96%; RT-HIIT = -8.57%), and cardiorespiratory fitness (HIIT-RT = +5.14%; RT-HIIT = +6.13%), with no difference between groups. Body composition and blood pressure did not change throughout the investigation for either group. Conclusion: Eight weeks of a combined HIIT and RT exercise program improved functional capacity of middle-aged and older women without altering blood pressure and body composition, regardless of the order of exercises.


Objetivo: Avaliar os efeitos da ordem do treinamento resistido (TR) e do treinamento intervalado de alta intensidade (HIIT) sobre a capacidade funcional, pressão arterial e composição corporal em mulheres de meia-idade e idosas. Metodologia: Vinte e duas mulheres foram aleatoriamente designadas em dois grupos: um grupo realizou TR seguido por HIIT (TR-HIIT, n = 10, 64,5 ± 7,94 anos) e outro grupo realizou HIIT seguido por TR (HIIT-TR, n = 10, 59,32 ± 4,44 anos). Ambos os grupos treinaram duas vezes por semana durante oito semanas. O TR foi composto por sete exercícios para a parte superior e inferior do corpo. O HIIT foi composto de pares alternados de corrida de alta intensidade (> 85% da frequência cardíaca máxima [FCM]) e intensidade moderada (60% FCM). Resultados: Foi encontrado um efeito dos programas de exercício para a resistência muscular de membros superiores do corpo (HIIT-TR = +9.43%; TR-HIIT = +6.16%), agilidade e equilíbrio dinâmico (HIIT-TR = -5,96%; TR-HIIT = -8.57%) e aptidão cardiorrespiratória (HIIT-TR = +5.14%; TR-HIIT = +6.13%), sem diferença entre os grupos. A composição corporal e a pressão arterial não se alteraram ao longo da investigação em nenhum dos grupos. Conclusão: Oito semanas de um programa combinado de exercícios de HIIT e de TR proporcionaram melhora na capacidade funcional de mulheres de meia-idade e idosas, sem alterar a pressão arterial e a composição corporal, independente da ordem de execução.
