Effects of multidomain interventions on skeletal muscle architecture and function in pre-frail older women: The WiiProtein study.

The aim was to investigate the effects of physical training with exergames and protein supplementation on musculoskeletal function, muscle architecture, and markers of physical frailty in pre-frail older women. Ninety participants were assigned to one of five groups: physical training using exergames (PTG); protein supplementation (PSG); physical training and protein supplementation (PTPSG); physical training and isoenergetic supplementation (PTISG); and control group (CG). We evaluated: strength and power of lower limbs; functional mobility; gait speed; handgrip strength; and muscle architecture. The PTPSG increased knee extensor and flexor strength (8.4% and 10.2% respectively), and knee extensor power (17.1%), reduced exhaustion (100%), and also reversed pre-frailty (43.8%). There were no significant differences among groups in all outcomes analyzed. Physical training using exergames with protein supplementation increased musculoskeletal function, reduced exhaustion, and reversed pre-frailty in older women.

Accuracy of Tools to Differentiate Single From Recurrent Fallers Pre-Frail Older Women.

Objectives: The objectives of this study were to analyze and compare musculoskeletal and functional performance and present cutoff points to differentiate pre-frail community-dwelling older women regarding their fall history: non fallers (0 falls), fallers (single fall), and recurrent fallers (≥2 falls). Method: This is a cross-sectional, retrospective study on 90 pre-frail community-dwelling older women (71.2 ± 4.49 years) according to Fried criteria. We assessed peak torque (PT) (isokinetic dynamometer), muscle architecture/mass (ultrasound/dual-energy X-ray absorptometry), and the following functional performance: usual gait speed (UGS), fast gait speed (FGS), walking speed reserve (WSR), cadence and step length, and timed up and go. Results: The recurrent fallers presented lower UGS (1.12 ± 0.18 vs. 1.29 ± 0.28 m/s; p = 0.05) and isometric PT of knee extensors than the fallers (89.88 ± 20.99 vs. 115.55 ± 23.09 Nm; p = 0.01), and lower FGS than the fallers (1.35 ± 0.26 vs. 1.5 ± 0.29 m/s; p = 0.03) and non-fallers (1.35 ± 0.26 vs. 1.52 ± 0.26 m/s; p = 0.01). The outcomes that differentiated the fallers from the non-fallers were both WSR calculated as a difference (WSRdiff) (≤0.26 m/s) and WSR calculated as a ratio (WSRratio) (≤1.25 m/s), while to differentiate the recurrent fallers from the non-fallers were FGS (≤1.44 m/s) and step length (≤73 cm). The following cutoff points might be used to differentiate recurrent fallers and fallers: UGS (≤1.12 m/s), FGS (≤1.34m/s), step length (≤73 cm), PT knee extension (≤114.2 Nm), PT knee flexion (≤46.3 Nm), and PT ankle dorsiflexion (≤22.1 Nm). Conclusion: Recurrent fallers community-dwelling pre-frail older women presented a worse musculoskeletal and functional performance when compared to the non-fallers and fallers. Gait speed, step length, PT of both knee extension and flexion, and ankle dorsiflexion can be used to identify both single and recurrent fallers pre-frail older women, contributing to guide interventions and prevent falls and fractures.

Reliability of HOME FAST BRAZIL-Self-Reported Version for Community-Dwelling Older Adults.

Objective: Verify the intra- and inter-rater reliability of the HOME FAST BRAZIL-Self-reported version and correlate household environmental risks with the history of falls by community-dwelling older adults. Method: Cross sectional study with 50 community-dwelling older adults who were screened by the cut-off point of the Mini Mental State Exam and replied to the HOME FAST BRAZIL-Self-reported version using two evaluators, on three occasions. The reliability analysis was determined by the Intra-class Correlation Coefficient (ICC), considering ICC > 0.70 as adequate. To test the correlations, the Spearman test was used. Results: The mean age of the participants was 73.2 ± 5.8 years. The inter- rater reliability of HOME FAST BRAZIL-Self-reported version was ICC 0.83 (IC95%, 0.70-0.90) and the Intra- reliability ICC 0.85 (IC95%, 0.74-0.91). A risk of falls was verified in 88% of the sample and four environmental risks presented significant correlations with the history of falls. Conclusions: The HOME FAST BRAZIL-Self-reported version presented adequate reliability for the evaluation of household environmental risks for community-dwelling older adults. Risks such as inadequate armchairs/ sofas, the absence of anti-slip mats in the shower recess, the presence of pets and inadequate beds require attention in the evaluation of household risks, due to their correlation with the occurrence of falls.

Effects of Exergames and Protein Supplementation on Body Composition and Musculoskeletal Function of Prefrail Community-Dwelling Older Women: A Randomized, Controlled Clinical Trial.

This study aimed to investigate the effects of exergames and protein supplementation on the body composition and musculoskeletal function of pre-frail older women. Methods: A randomized controlled clinical trial was conducted with 90 pre-frail older women (71.2 ± 4.5 years old) divided into five groups: control (CG); exergames training (ETG); protein supplementation (PSG); exergames combined with protein supplementation (ETPSG); exergames combined with isoenergetic supplementation (ETISG). The primary outcomes were pre-frailty status, body composition (appendicular muscle mass (ASM); appendicular muscle mass index (ASMI)) assessed by dual energy X-ray absorptiometry and gastrocnemius muscle architecture via ultrasound. Secondary outcomes were protein intake, plasma levels of interleukin (IL)-6, plantar and dorsiflexion isokinetic peak torque, and handgrip strength (HS). Data were analyzed using an ANOVA mixed model test and Bonferroni post hoc test (p < 0.05). The ETG showed a reduction of ASM (16.7 ± 3.4 vs. 16.1 ± 3.3 kg; Δ = -0.5; p = 0.02; d = 0.26) and ASMI (6.8 ± 0.9 vs. 6.5 ± 0.9 kg; Δ = -0.2; p = 0.03; d = 0.35), without changing ASM in other groups. The average protein intake in the supplemented groups (PSG and ETPSG) was 1.1 ± 0.2 g/kg/day. The dorsiflexion peak torque increased 11.4% in ETPSG (16.3 ± 2.5 vs. 18.4 ± 4.2 Nm; p = 0.021; d = -0.58). The HS increased by 13.7% in ETG (20.1 ± 7.2 vs. 23.3 ± 6.2 kg, Δ = 3.2 ± 4.9, p = 0.004, d = -0.48). The fatigue/exhaustion reduced by 100% in ETG, 75% in PSG, and 100% in ETPSG. Physical training with exergames associated with protein supplementation reversed pre-frailty status, improved the ankle dorsiflexors torque, and ameliorated fatigue/exhaustion in pre-frail older women.

Does Physical Dance Training with Virtual Games Change Muscle Quality of Community-Dwelling Older Women?

Objective: The aim of the study is to analyze the effects of physical dance training with a virtual game on muscle quality (MQ) of community-dwelling older women. Materials and Methods: In total, 46 older women participated in the study and were assigned to either a control group (CG, n = 25, 71 ± 5 years) or training group (TG, n = 21, 69 ± 4 years). The following assessments were performed at baseline and after 12 weeks: quadriceps, ankle plantar flexor, and dorsiflexor isokinetic peak torque (PT) (Biodex System 4 Dynamometer); quadriceps cross-sectional area (CSA) measured using magnetic resonance imaging; intramuscular noncontractile tissue (IMNCT) (Image-Pro Plus 4.5.0.29 for Windows); and MQ (ratio of quadriceps PT to CSA). Each week for 12 weeks, the TG undertook three 40-minute sessions of physical training with the "Dance Central" game for Xbox 360® with Kinect, while the CG was instructed to maintain usual activities of daily living. Results: The TG increased quadriceps eccentric PT at 60°/s (P = 0.04) and ankle plantar flexor concentric PT at 60°/s (P = 0.02) when compared with the CG. No significant difference in quadriceps CSA, IMNCT, and MQ was observed. Conclusion: Physical dance training with virtual games can increase quadriceps and ankle plantar flexor strength without changing IMNCT and MQ of community-dwelling older women. Trial number: RBR-8xkwyp (ensaiosclinicos.gov.br-Brazilian Clinical Trials Registry).

Immediate analgesic effect of transcutaneous electrical nerve stimulation (TENS) and interferential current (IFC) on chronic low back pain: Randomised placebo-controlled trial.

OBJECTIVE: To compare the immediate analgesic effect of transcutaneous nerve stimulation (TENS) and interferential current (IFC), with different combinations of parameters, in individuals with chronic low back pain (CLBP). METHODOLOGY: 280 individuals with CLBP were included in the study, both genders, randomized in 8 groups: GI2KHz/100Hz, GI2KHz/2Hz, GI4KHz/100Hz, GI4KHz/2Hz, placebo interferential group (GIP), GT100Hz, GT2Hz, and placebo TENS group (GTP). All individuals underwent a single application of TENS or IFC for 30min. The assessments were carried out prior to the intervention, as well as immediately after, with the following outcomes: pain intensity (Numeric Pain Rating Scale-NPRS), qualitative pain characteristics (McGill Pain Questionnaire-MPQ), and pressure pain threshold (PPT) by pressure algometry (PA) in 4 points of the low back region. RESULTS: In the intergroup comparison of NPRS, all intervention groups showed greater pain reduction compared to GTP (p < 0.05). In the total MPQ score, the groups that obtained significant results (p < 0.05) when compared to GTP were GT100Hz and GT2Hz, while the groups GT100Hz and GI4KHz/100Hz were significant when compared to GIP. In the PA, GI4KHz/100Hz showed an increase in the PPT in all points compared to GTP and GI2KHz/100Hz. CONCLUSION: Both TENS and IFC presented immediate analgesic effect in CLBP, with emphasis on the interferential current of 4 KHz modulated at 100Hz.

Análise do desenvolvimento neuropsicomotor de pré-termos em ambulatório multidisciplinar: um olhar da fisioterapia / Analysis of neuropsychomotor development of preterm in multidisciplinary ambulatory: a view of physiotherapy

INTRODUÇÃO: Desde a gestação até o nascimento, o desenvolvimento neuropsicomotor é influenciado por diversos fatores biopsicossociais. Tal influência pode ser ainda mais acentuada em recém-nascidos pré-termo devido a internação na Unidade de Terapia Intensiva Neonatal, por isto, bebês pré-termos estão mais susceptíveis a essas influências. OBJETIVO: Analisar sob a ótica do fisioterapeuta o desenvolvimento neuropsicomotor de pré-termos em ambulatório multidisciplinar de um hospital público. METODOLOGIA: Estudo observacional e longitudinal, ambispectivo, de 19 crianças nascidas prematuras de 0 a 12 meses de idade corrigida, sendo critério de exclusão crianças com alterações cognitivas e/ou genéticas ou não terem assinado o termo de consentimento. Os dados foram coletados por meio da análise de prontuários entre agosto de 2017 e dezembro de 2018, o desenvolvimento avaliado por meio do Teste Triagem Denver II, em dois momentos: A1 e A2, em sua admissão e retorno ao serviço após a alta da Unidade de Terapia Intensiva Neonatal e para análise da relação entre mãe e bebê foi utilizada a Avaliação Vínculo Mãe/filho apenas em A1. As estimulações eram realizadas por meio de orientações e folder educativo para os pais e responsáveis. Os dados foram analisados, por meio de média, desviopadrão, frequência absoluta e relativa, mediana, minimo e máximo e Teste de Wilcoxon para os domínios do Teste Denver II A1 em comparação a A2, utilizando o programa SPSS versão 20.0. RESULTADOS: Foram acompanhadas 19 crianças, destas 79% foram classificadas com desenvolvimento normal no A1. As crianças que apresentaram déficits no A1 (10,5%), superaram no A2. Porém, no segundo atendimento, algumas passaram a apresentar dificuldade em novas tarefas/domínio (motor, motor fino e pessoal-social), de modo que 31,5% apresentaram desenvolvimento geral anormal em A2. Foi encontrada diferença significativa (p=0,02) ao comparar as classificações gerais de Denver II nos dois momentos de avaliação. O vínculo mãe-filho foi classificado como fraco (média de 5,8 pontos). CONCLUSÃO: Observou-se que os bebês superaram os atrasos identificados na primeira avaliação, embora os resultados no Denver tiveram variações ao longo do tempo. Dessa forma, acredita-se que o perfil familiar identificado nesta pesquisa somada a abordagem multiprofissional possa ter favorecido o desenvolvimento neuropsicomotor dos bebês prematuros com até 12 meses de idade corrigida.

INTRODUCTION: From gestation to birth, neuropsychomotor development is influenced by several biopsychosocial factors. This influence can be even more accentuated in preterm newborns due to their admission to the Neonatal Intensive Care Unit, so preterm babies are more susceptible to these influences. OBJECTIVE: To analyze the neuropsychomotor development of preterm babies in a multidisciplinary outpatient clinic of a public hospital. METHODOLOGY: Observational and longitudinal, ambispective study of 19 children born prematurely from 0 to 12 months of corrected age, being exclusion criteria children with cognitive and/or genetic alterations or not having signed the consent form. The data were collected through the analysis of medical records between August 2017 and December 2018, the development evaluated through the Denver II Triage Test, in two moments: A1 and A2, on their admission and return to service after discharge from the Neonatal Intensive Care Unit and for analysis of the relationship between mother and baby the Evaluation Mother/Son bond only in A1 was used. The stimulations were carried out employing orientation and educational folder for parents and guardians. The data were analyzed by means of mean, standard deviation, absolute and relative frequency, median, minimum and maximum, and Wilcoxon Test for the domains of Denver II A1 compared to A2, using the SPSS program version 20.0. RESULTS: 19 children were accompanied, and 79% of these were classified with normal development in A1. The children who presented deficits in A1 (10.5%), surpassed in A2. However, in the second attendance, some started to present difficulties in new tasks/domains (motor, fine motor, and personal-social), so that 31.5% presented abnormal general development in A2. A significant value was found when comparing the Denver II general classification in A1 with A2 (p=0.02). The mother-child bond was classified as weak (average of 5.8 points). CONCLUSION: It was observed that babies overcame the delays identified in the first evaluation, although the results in Denver had variations over time. Thus, it is believed that the family profile identified in this research plus the multi-professional approach may have favored the neuropsychomotor development of premature babies up to 12 months of corrected age.

Frailty prevalence and related factors in older adults from southern Brazil: A cross-sectional observational study.

OBJECTIVES: To determine the prevalence of frailty and the association of sociodemographic characteristics, clinical aspects, and functional capacity with the frailty status of community-dwelling older adults from Curitiba, Southern Brazil. METHODS: This cross-sectional observational study included 1,716 participants aged ≥60 years. Frailty was assessed using the Fried phenotype indicators of weakness, exhaustion, low activity, slowness, and weight loss. Sociodemographic characteristics, clinical aspects, and functional capacity and functionality were evaluated and compared between the sexes and the different frailty statuses (non-frail, prefrail, and frail). Multinomial logistic regression models were used to identify associations (p<0.05). RESULTS: A high prevalence of frailty (15.8%) and prefrailty (65.3%) were observed, and both were higher in female than in male individuals. The most predominant frailty criterion was weakness, followed by exhaustion. Compared with the non-frail elderly, the prefrail and frail elderly were older in age and presented more health problems, greater dependency for basic and instrumental activities of daily living, and reduced lower extremity strength performance and functional mobility. The highest proportion of illiterate individuals, individuals with 1-4 years of education, widowed individuals, polypharmacy, and possible cognition problems and diseases were seen in the frail elderly group. Moreover, the risk of being prefrail and frail was higher in those who were older and had more health problems, higher body mass index, and reduced lower extremity strength performance. Greater calf circumference and independence in activities of daily living were protective factors for prefrailty and frailty. Furthermore, lower functional mobility increased the chances of being frail. CONCLUSIONS: The prevalence of frailty was more pronounced in female than in male individuals, mainly because of a decline in force. Prefrailty was 4 times more prevalent than frailty, and the presence of health problems and reduced functional capacity increased the chances of being prefrail and frail.

The HOME FAST BRAZIL self-report version: translation and transcultural adaptation into Brazilian Portuguese.

OBJECTIVE: To translate and cross-culturally adapt the Home Falls and Accidents Screening Tool Self-report into Brazilian Portuguese and to correlate with the history of falls. METHODS: The translation and transcultural adaptation process followed international parameters. The Home Falls and Accidents Screening Tool Brazil Self-report, the Mini-Mental State Examination and the history of falls were applied to 10 elderly in the pre-test and to 41 in the final. Demographic and anthropometric data were also evaluated. Spearman correlation coefficient was performed. RESULTS: The participants considered the questionnaire easy to understand and did not report any doubts to answer the final version. There was significant correlation between: Home Falls and Accidents Screening Tool Brazil Self-report score and number of falls (ρ = 0.31, p = 0.02) and the lighting and bathroom domains with presence of falls at home (ρ = 0.44, p = 0.00 and ρ = 0.33, p = 0.02, respectively). The questionnaire indicated fall's risk scoring, 10(±2). CONCLUSION: The Home Falls and Accidents Screening Tool Brazil Self-report showed to be comprehensible and feasible tool for self-assessment of domiciliary falls risk in Brazilian older people. The scores indicated fall's risk and were associated with the history of falls.

Effects of physical training with the Nintendo Wii Fit Plus® and protein supplementation on musculoskeletal function and the risk of falls in pre-frail older women: Protocol for a randomized controlled clinical trial (the WiiProtein study).

BACKGROUND: Frailty is one of the key geriatric syndromes and is related to the loss of functional independence. However, the practice of physical training (PT) combined with protein supplementation (PS) may improve musculoskeletal function (MF). OBJECTIVE: To verify the effect of PT using 'exergames' with or without PS on MF, nutritional status, and risk of falls in pre-frail older women. METHOD: The protocol is for a randomized controlled clinical trial with a sample of pre-frail older women, divided into 5 groups: control group; PT using exergames; PS; PT using exergames combined with PS; PT using exergames combined with isoenergetic supplementation. The primary outcomes will be: the strength and power of the lower limbs, assessed by isokinetic dynamometer and the sit-and-stand test carried out 5 times; muscle architecture, assessed by ultrasound; body composition, assessed by anthropometric measurements, bioelectrical impedance and dual energy X-ray absorptiometry; and functional mobility and risk of falls, assessed using the Timed-Up and Go test. The secondary outcomes will be: centre of pressure (CoP), assessed using a force plate; and fear of falling, assessed using the Falls Efficacy Scale - International, Brazil. PT using exergames with a gradual increase in the mass weighted vest will be carried out twice a week for 50 min over 3 months. The supplements will be ingested 5 days a week for 3 months. All outcomes will be assessed before and after 3 months. DISCUSSION: The WiiProtein study will be the first clinical trial to examine the effects of PT using exergames with progressive resistance, which may or may not be combined with PS, on MF, nutritional status, and risk of falls in pre-frail older women.

Effects of exergame training on the health promotion of young adults / Efeitos do treinamento com exergames na promoção da saúde de adultos jovens

Abstract Introduction: Training with exergames has been prescribed for health problems prevention, however, little is known about its influence on the self-perception of the physical condition and on the physical and motor skills (PMS). Objective: To investigate the effects of exergames (EXG) on the self-perception of the physical condition, level of physical activity and PMS in healthy young adults. Methods: Forty young adults, of both genders, were allocated by convenience into Control Group (CG, n = 20, 21.85 ± 0.62 years old), the individuals did not perform the physical training with exergames, and Intervention Group (IG, n = 20, 23.10 ± 0.61 years old), the subjects practiced exergames training (XBOX360 Kinect ®), in pairs, twice a week, for 12 weeks. Anthropometric measurements; self-perceived physical condition (International Fitness Scale-IFIS); International Physical Activity Questionnaire (IPAQ) and PMS (flexibility; abdominal endurance; upper limb strength and endurance, agility and velocity) were evaluated. Results: The IG presented better self-perception of the physical condition; increased physical activity level in the leisure domain and enhanced PMS after 12 weeks of intervention, compared to the CG. Conclusion: The EXG was efficient to improve skeletal muscle function, to contribute to physical exercise adherence and to promote physical health in active young adults.

Resumo Introdução: O treinamento com exergames tem sido prescrito para prevenção em saúde, no entanto, pouco se sabe sobre sua influência na autopercepção da condição física e nas capacidades físico-motoras. Objetivo: Investigar os efeitos dos exergames (EXG) sobre a autopercepção da condição física, nível de atividade física (AF) e capacidades físico-motoras (CFM) de adultos jovens saudáveis. Métodos: Quarenta adultos jovens, de ambos os sexos, foram distribuídos por conveniência em Grupo Controle (GC, n = 20, 21,85 ± 0,62 anos) que não realizou treinamento físico e Grupo Intervenção (GI, n = 20, 23,10 ± 0,61 anos) que realizou treinamento físico com videogame (XBOX360 Kinect®), em duplas, 2 vezes por semana, durante 12 semanas. A avaliação consistiu na verificação das medidas antropométricas; auto-percepção da condição física (International Fitness Scale-IFIS); nível de Atividade Física (AF, questionário IPAQ) e CFM (flexibilidade, resistência abdominal, força e resistência dos membros superiores agilidade e velocidade). Resultados: O GI apresentou melhora na autopercepção da condição física; aumento no nível de AF no domínio lazer e melhora nas CFM após 12 semanas de intervenção, em comparação com o grupo controle. Conclusão: O EXG foi eficaz para incrementar a função musculoesquelética, favorecer a aderência ao exercício físico e promover a saúde física em adultos jovens ativos.

Efeitos do treinamento com Kinect Sports e Kinect Adventures na resistência da musculatura lombopélvica de adultos jovens saudáveis: ensaio clínico não randomizado / Los efectos del entrenamiento con Kinect Sports y Kinect Adventures en la resistencia de la musculatura lumbar y pélvica de adultos jóvenes saludables: estudio clínico no aleatorio / Effects of training with Kinect Sports and Kinect Adventures in the resistance of lumbar-pelvic muscles of healthy young adults: non-randomized clinical trial

RESUMO O treinamento com exergames (EXG) tem sido utilizado como técnica para prevenção em saúde, embora pouco se saiba sobre sua influência na resistência da musculatura da região lombopélvica. Assim, analisou-se os efeitos dos jogos Kinect Sports ® e Kinect Adventures ® sobre a resistência muscular da região lombopélvica de adultos jovens saudáveis. Tivemos 40 participantes (26 mulheres e 14 homens, com idade entre 18 e 30 anos) divididos por conveniência em grupo controle (GC, n=20) e grupo intervenção (GI, n=20), e submetidos a avaliações da resistência da musculatura flexora, extensora e flexora lateral do tronco, em três períodos: inicial (T0), depois de cinco semanas (T5) e depois de 12 semanas (T12). Somente o GI realizou treinamento com videogame, jogos Kinect Sports ® e Kinect Adventures ® (Xbox 360 Kinect®), em duplas, duas vezes por semana, durante 12 semanas. Para analisar as diferenças entre os grupos foi utilizado o teste de ANOVA mista com medidas repetidas design 2 (grupo de tratamento: GC vs. GI) x3 (testes do complexo lombopélvico: T0 vs. T5 vs. T12) (p<0,05). Resultados: O GI apresentou aumento significativo da resistência de extensores de tronco e flexores laterais de tronco (F2,76=3.947, p=0,03; F2,76=3.763, p=0,02, respectivamente) depois de 12 semanas de intervenção com o videogame, em comparação ao GC. Concluiu-se que o treinamento com EXG (Xbox 360 Kinect Sports ® e Kinect Adventures ®) incrementou a resistência da musculatura da região lombopélvica de adultos jovens saudáveis. Este protocolo pode ser considerado na prevenção de desordens musculoesqueléticas da região lombar.

RESUMEN El entrenamiento con los videojuegos activos viene siendo empleado como técnica para promover la salud, pero todavía poco se sabe acerca de su influencia en la resistencia de la musculatura lumbar y pélvica. En este trabajo se analizaron los efectos de los juegos Kinect Sports® y Kinect Adventures® en la resistencia de la musculatura lumbar y pélvica de adultos jóvenes saludables. Se dividieron 40 participantes (26 mujeres y 14 varones, con edades entre 18 y 30 años) por conveniencia en el grupo control (GC, n=20) y en el grupo de intervención (GI, n=20), y se les sometieron al análisis de resistencia del músculo flexor, extensor y flexor lateral del tronco, en tres periodos: inicial (T0), después de cinco semanas (T5) y después de 12 semanas (T12). El G1 solo realizó entrenamiento con los videojuegos Kinect Sports® y Kinect Adventures® (Xbox 360 Kinect®), en parejas, dos veces semanales, durante 12 semanas. En el análisis de las diferencias entre grupos se empleó la prueba ANOVA mixta con repetidas medidas design 2 (grupo de entrenamiento: GC vs. GI) x3 (pruebas del complejo lumbar y pélvico: T0 vs. T5 vs. T12) (p<0,05). Comparado al GC, el GI presentó un aumento significativo en la resistencia de los extensores del tronco y en los flexores laterales del tronco (F2,76=3.947, p=0,03; F2,76=3.763, p=0,02, respectivamente) tras las 12 semanas de entrenamiento con los videojuegos. Se concluye que el entrenamiento con videojuegos activos, Xbox 360 Kinect Sports® y Kinect Adventures®, mejoró la resistencia de la musculatura lumbar y pélvica de los participantes, y puede ser empleado en la prevención de trastornos musculoesqueléticos lumbares.

ABSTRACT Exergames training (EXG) has been used as a technique for health prevention, however, little is known about its influence on the endurance of lumbar-pelvic muscles. The effects of Kinect Sports ® and Kinect Adventures ® on the endurance of lumbar-pelvic muscles in healthy young adults were analyzed. Forty participants (26 women and 14 men, from 18 to 30 years old) were sorted by convenience into a control group (CG, n = 20) and an intervention group (IG, n=20). The muscles of the trunk (flexor, extensor and lateral flexor) were assessed in three periods: before the intervention (T0), after five weeks (T5) and after 12 weeks (T12). Only the IG underwent training with Kinect Sports ® and Kinect Adventures ® (XBOX360 Kinect®), in pairs, twice a week, during 12 weeks. To analyze the differences between groups, mixed ANOVA test was used with repeated measures design 2 (treatment group: CG vs. IG) x3 (lumbar-pelvic complex tests: T0 vs. T5 vs. T12) (p<0.05). The IG showed a significant increase in the endurance of trunk extensors and lateral flexors (F2,76=3.947, p=0.03; F2,76=3.763, p=0.02), respectively, after 12 weeks of intervention, compared to the CG. It was concluded that EXG training (XBOX360 Kinect Sports® and Kinect Adventures®) improved the resistance of the lumbar-pelvic muscles of healthy young adults. This protocol may be considered an instrument for the prevention of musculoskeletal disorders in the lumbar region.
