ABSTRACT

Objetivo: Evaluar las variables predictoras de la calidad de vida en población adulta latinoamericana en situación de pandemia durante la cuarentena por COVID-19. Métodos: Estudio descriptivo, trasversal. La muestra estuvo compuesta por 3101 habitantes adultos de Chile, Colombia, México y Perú. Los factores que aumentaron la probabilidad de tener una baja calidad de vida se identificaron mediante un análisis de regresión logística. Estos análisis fueron ajustados por estado nutricional, edad y procedencia geográfica. Resultados: Ser de género femenino (OR=1.73; p=0.001), físicamente inactivo/a (OR=1.85; p=0.001), consumir tabaco (OR=1.29; p=0,026), alcohol (OR=1.31; p=0,002) y comida chatarra (OR=2.04; p=0,001) aumentaron la probabilidad de tener una disminución en la dimensión salud general de la calidad de vida durante una cuarentena por Covid-19. Conclusiones: Los hallazgos en este estudio confirman la necesidad de promover hábitos y estilos de vida saludables en la población durante las cuarentenas en una pandemia como, por ejemplo, una dieta sana, practicar actividad física y evitar estar mucho tiempo sentado.


Objective: To evaluate the predictive variables of the quality of life in the Latin American adult population in a pandemic situation during the Covid-19 quarantine. Methods: Descriptive, cross-sectional study. The population was composed of 3,101 adult inhabitants of Chile, Colombia, Mexico and Peru. Factors that increased the likelihood of poor quality of life were identified using logistic regression analysis. These analyzes were adjusted for nutritional status, age, and geographic origin. Results: Being female (OR=1.73; p=0.001), physically inactive (OR=1.85; p=0.001), consuming tobacco (OR=1.29; p=0.026), alcohol (OR=1.31; p=0.002) and junk food (OR=2.04; p=0.001) increased the probability of having a decrease in the general health dimension of quality of life during a Covid-19 quarantine. Conclusions: The findings in this study confirm the need to promote healthy habits and lifestyles in the population during quarantines in a pandemic, such as a healthy diet, practicing physical activity and avoiding prolonged sitting.

ABSTRACT

Introducción: El aumento del uso de teléfono celular y la baja actividad física en universitarios se han asociado a un bajo rendimiento académico. Objetivo: Analizar la relación entre tiempo de uso del teléfono celular, el nivel de actividad física y rendimiento académico en estudiantes universitarios. Materiales y métodos: Estudio de alcance correlacional y temporalidad longitudinal. Participaron 36 estudiantes universitarios, a quienes se evaluó durante un semestre, el tiempo que destinaron al uso de teléfono celular, a través de la aplicación "Moment" y la actividad física mediante la aplicación "Pacer". Se registró el rendimiento académico con el promedio de notas. Resultados: Durante el semestre, los hombres realizaron mayor actividad física y utilizaron por mayor tiempo el teléfono. En periodos de evaluación, las mujeres tuvieron mayor actividad física y menor uso del teléfono celular (p=0,019 y p=0,033, respectivamente). Además, los hombres que tuvieron mejores notas promedio hacían un menor número de pickups diarios (p=0,032). Conclusiones: Los hombres universitarios son físicamente más activos y usan más el celular durante el semestre, aunque en periodo de evaluaciones las mujeres tienden a ser más activas y usar menos tiempo su celular. Los universitarios que usan menos el teléfono celular tienen mejor rendimiento académico.


Introduction: Low academic performance of college students has been associated with an increase in time spent on cell phones and a low physical activity. Objective: To analyze the relationship between time spent on cell phones, physical activity level, and academic performance in college students. Materials and methods: A study with a correlational and longitudinal temporality approach. During a semester, 36 college students were assessed on the time they spent using cell phones and their physical activity levels through the Moment and Pacer applications, respectively. Academic performance was monitored through report cards. Results: Men engaged in more physical activity and used cell phones more frequently during the analyzed period, while women showed higher physical activity levels and lower cell phone usage during evaluation periods (p=0.019 y p=0.033, respectively). Also, men who had better grade averages showed lower number of daily pickups (p=0.032). Conclusions: College men show higher physical activity levels and longer cell phone usage during the semester, while women tend to be more active and use their cell phones less frequently during evaluation periods. College students who use cell phones less regularly also have a better academic performance.

ABSTRACT

RESUMEN Introducción: El envejecimiento patológico provoca cambios anatomofisiológicos responsables de generar deterioro en la condición física y calidad de vida de las personas mayores. Así también se ha observado un aumento en la presencia de síndromes geriátricos como la fragilidad física. Objetivo: Determinar si existe asociación entre la condición física y calidad de vida con la fragilidad en personas mayores. Métodos: Estudio correlacional. Se incluyeron 84 personas mayores de 65 años (62 mujeres y 22 hombres) entre agosto y septiembre del año 2021 en las regiones metropolitana y Maule, Chile. Se midieron la condición física, calidad de vida y fragilidad. La condición física se evaluó con la batería Senior Fittnes Test y la calidad de vida fue medida con el cuestionario World Health Organization Quality of Life Old (WHOQOL-OLD). La fragilidad se determinó con el fenotipo de Fried. Se utilizaron tablas de contingencia para asociar las variables de estudio con la fragilidad a través de la prueba de ji cuadrado. Resultados: La fragilidad se asoció con algunos componentes de la condición física como fuerza del tren superior (p= 0,038), fuerza del tren inferior (p= 0,018), flexibilidad del tren inferior (p= 0,004), resistencia aeróbica (p= 0,038), agilidad y equilibrio dinámico (p= 0,002). También, se observaron asociaciones significativas con dimensiones de calidad de vida como autonomía (p= 0,007), actividades del pasado, presente y futuro (p= 0,018), participación social (p= 0,006) e intimidad (p= 0,038). Conclusión: Existe asociación entre fragilidad con dimensiones de calidad de vida y con variables de la condición física.


ABSTRACT Introduction: Pathological aging causes anatomophysiological changes responsible for generating deterioration in the physical condition and quality of life of the elderly. Thus, an increase in the presence of geriatric syndromes such as physical frailty has also been observed. Objective: To determine if there is an association between physical condition and quality of life with the frailty in older adults. Methods: Correlational study. 84 people over 60 years of age (62 women and 22 men) were included. Physical fitness, quality of life and frailty were measured. Physical fitness was assessed with the Senior Fitness Test battery and quality of life was measured with the World Health Organization Quality of Life Old (WHOQOL-OLD) questionnaire. Frailty was determined with the Fried phenotype. Contingency tables were used to associate the study variables with frailty through the Chi-square test. Results: Frailty was associated with some components of physical fitness such as upper body strength (p= 0.038), lower body strength (p= 0.018), lower body flexibility (p= 0.004), aerobic endurance (p= 0.038), agility and dynamic balance (p= 0.002). Also, significant associations were observed with quality of life dimensions such as autonomy (p= 0.007), past, present and future activities (p= 0.018), social participation (p= 0.006) and intimacy (p= 0.038). Conclusion: There is an association between frailty with dimensions of quality of life and with variables of physical fitness.

ABSTRACT

Background: The confinement caused by the COVID-19 pandemic changed the lifestyles of the population affecting their levels of physical activity. Aim: To determine the factors associated with a low level of physical activity in adults during confinement during the COVID-19 pandemic. Material and Methods: Adults from Chile, Colombia, México and Perú were invited through social networks to answer an online survey. Questions about sociodemographic, health status and lifestyle variables were included. The level of physical activity and sedentary behavior were determined through the short version of the International Physical Activity Questionnaire (IPAQ). Results: The survey was answered by 3,362 adults aged between 18 and 60 years. Respondents more likely to be inactive were women, those with less than eight years of education, those with overweight or obesity, those who smoked at least one cigarette a day, consumed alcohol four or more times a week, slept less than six hours per day and spent more than 6 hours per day in sedentary behaviors. Conclusions: These findings provide a sociodemographic and lifestyle profile associated with physical inactivity during the period of confinement in Latin American adults. The results confirm the need to promote healthy lifestyles in the population during periods of confinement.

ABSTRACT

RESUMEN Introducción: La pandemia por la COVID-19 ha generado distanciamiento social, lo cual provoca disminución de la práctica de actividad física y menor calidad de vida relacionada con la salud. Objetivo: Relacionar el nivel de actividad física con la calidad de vida relacionada con la salud, en adolescentes, durante el confinamiento por la COVID-19. Métodos: Estudio transversal que evaluó 184 estudiantes (61,4 % mujeres) con una edad media de 13,97 + 1,69 años, residentes en la región del Maule, Chile. Se emplearon dos encuestas de autoaplicación, la versión corta del Cuestionario Internacional de Actividad Física y la versión validada en población chilena, del KIDDO-KINDL. Resultados: Se presentó correlación directa y significativa entre el tiempo total de actividad física leve con la autoestima (p= 0,043) y, entre el tiempo total sentado con el bienestar emocional (p= 0,025), autoestima (p= 0,014), escuela (p= 0,031) y puntaje total de calidad de vida (p= 0,006) para el total de la muestra. Solo las mujeres presentaron correlación (p< 0,05) entre el tiempo total sentado con la familia, escuela y puntaje total de calidad de vida. Además, se encontraron diferencias significativas (p< 0,05) en el tiempo total de actividad física moderada, escuela y puntaje total de calidad de vida a favor de los hombres. Conclusión: Existe relación entre el tiempo total de actividad física con la autoestima y, entre el tiempo total sentado con el bienestar emocional, autoestima, escuela y puntaje total de calidad de vida en adolescentes durante el confinamiento por la COVID-19.


ABSTRACT Introduction: The COVID-19 pandemic has generated social distancing, causing a decrease in the practice of physical activity and a lower health-related quality of life. Objective: To relate the level of physical activity with health-related quality of life in youth, during COVID-19 lockdown. Methods: Cross-sectional study that evaluated 184 students (61,4 % female) with a mean age of 13,97 + 1,69 years, residing in the Maule region, Chile. Two self-application surveys were applied, with the short version of the International Physical Activity Questionnaire and the valid version in the Chilean population of the KIDDO-KINDL. Results: There was a direct and significant correlation between the total time of mild physical activity with self-esteem (p= 0,043) and, between the total sitting time with emotional well-being (p= 0,025), self-esteem (p= 0,014), school (p= 0,031), and total quality of life score (p= 0,006) for the total sample. Only females showed a correlation (p< 0,05) between total time sitting with family, school, and total quality of life score. In addition, significant differences (p< 0,05) were found in the total time of moderate physical activity, school, and total quality of life score in favor of males. Conclusion: There is a relationship between the total time of physical activity with self-esteem and between the total sitting time with emotional well-being, self-esteem, school, and total quality of life score in youth during COVID-19 lockdown.

ABSTRACT

SUMMARY: High-intensity interval training (HIIT) is zed by achieving similar effects to conventional physical and physiological training in a shorter time, allowing its dissemination in the sports field. The present study was aimed to analyze the effects of a HIIT program on body composition and general and specific physical fitness in Chilean female field hockey players. Experimental, repeated measures, simple blind, parallel groups, and a quantitative approach were used. The participants were randomized, and distributed into a control group (CG; n= 10) that maintained regular field hockey training and an experimental group (EG; n= 10) that also received complementary training with HIIT. Body composition (muscle mass and adipose mass), general physical fitness (jump performance with countermovement jump [CMJ] and maximum oxygen consumption [VO2max] were evaluated with the test Course-Navette), and specific physical fitness (pushing speed, dribbling speed, and shooting accuracy) were assessed with established protocols. Pre- and post-intervention comparisons were made with Student's t and Wilcoxon tests, considering p<0.05. The main results indicate that the EG presented a significant increase in muscle mass (p = 0.024; d = 0.62), CMJ (p = 0.005; d = 1.10), VO2max (p = 0.001; d = 1.58) and a significant reduction in adipose mass (p = 0.023; d = 0.36) and time in pushing speed (p = 0.028; d = 0.79). The CG did not present significant changes in any of the variables analyzed, and no significant differences were reported between the groups. In conclusion, eight weeks of HIIT significantly increases muscle mass, jump performance, and VO2max and significantly reduces adipose mass and time in pushing speed in Chilean female field hockey players.


RESUMEN: El entrenamiento intervalado de alta intensidad (EIAI) se caracteriza por conseguir en un menor tiempo efec- tos similares al entrenamiento convencional a nivel físico y fisiológico, lo que ha permitido su difusión en el ámbito deportivo. El objetivo del presente estudio fue analizar los efectos de un programa de EIAI sobre la composición corporal, condición física general y específica en mujeres chilenas que practican hockey césped. Estudio experimental, de medidas repetidas, simple ciego, grupos paralelos y enfoque cuantitativo. Las participantes fueron aleatorizadas y distribuidas en grupo control (GC; n=10) que mantuvo los entrenamientos regulares de hockey césped y grupo experimental (GE; n=10) que además recibió de complemento EIAI. Se evaluó la composición corporal (masa muscular y masa adiposa), condición física general (capacidad de salto con el salto contra movimiento [CMJ] y consumo máximo de oxígeno [VO2máx] con la prueba Course de Navette) y condición física específica (velocidad de empuje, velocidad de dribling y precisión de tiro) con protocolos establecidos. Se realizaron comparaciones pre y post intervención con las pruebas t de Student y Wilcoxon, considerando un p<0,05. Los principales resultados indican que el GE presentó un aumento significativo de la masa muscular (p=0,024; d=0,62), CMJ (p=0,005; d=1,10), VO2máx (p=0,001; d=1,58) y, una reducción significativa, de la masa adiposa (p=0,023; d=0,36) y del tiempo en la velocidad de empuje (p=0,028; d=0,79). El GC no presentó cambios significativos en ninguna de las variables analizadas, mientras que no se reportaron diferencias significativas entre los grupos. En conclusión, ocho semanas de EIAI aumentan significativamente la masa muscular, capacidad de salto y VO2máx, además de reducir significativamente la masa adiposa y el tiempo en la velocidad de empuje en mujeres chilenas que practican hockey césped.

ABSTRACT

Introducción: La cuarentena y el aislamiento social son las medidas más recomendadas por las autoridades de salud con el objetivo de reducir la interacción social entre las personas y disminuir el riesgo de contagio por la COVID-19 en la comunidad. Sin embargo, estas restricciones y limitaciones pueden traer consecuencias en la calidad de vida relacionada con la salud de adultos jóvenes. Objetivo: Comparar la calidad de vida autorreportada entre un entorno sin pandemia vs. un contexto bajo alerta sanitaria por la COVID-19, en adultos jóvenes. Métodos: Estudio retrospectivo; 157 adultos jóvenes (63 mujeres y 94 hombres), de entre 18 y 28 años, respondieron el cuestionario de salud SF-36 en 2 situaciones: contexto sin pandemia (septiembre de 2019) y contexto de pandemia (abril de 2020). El SF-36 incluye 36 preguntas agrupadas en 8 ítems: función física, rol físico, dolor corporal, salud general, vitalidad, función social, rol emocional y salud mental. Resultados: Al comparar las evaluaciones entre los contextos con y sin pandemia, se observó una disminución de la calidad de vida en las dimensiones vitalidad (p = 0,004), función social (p = 0,001), rol emocional (p = 0,001), salud mental (p = 0,003) y salud general (p = 0,001). Las dimensiones más alteradas fueron el rol emocional y la salud general, las cuales disminuyeron un 39,5 por ciento y 21,0 por ciento, respectivamente. Conclusión: La calidad de vida relacionada con la salud de adultos jóvenes se ve disminuida en un contexto de cuarentena por la COVID-19, principalmente, en las dimensiones psicológicas y sociales(AU)


Introduction: Quarantine and social isolation are the actions most recommended by health authorities with the aim of reducing social interaction between people and reducing the risk of COVID-19 infection in the community. However, these restrictions and limitations can have consequences on the health-related quality of life of young adults. Objective: To compare the self-reported quality of life between a pandemic-free environment versus a context of COVID-19 pandemic in young adults. Methods: Retrospective study; 157 young adults (63 women and 94 men) between 18 and 28 years old answered the SF-36 health questionnaire in 2 situations: context without pandemic (September 2019) and context of pandemic (April 2020). The SF-36 includes 36 questions grouped into 8 items: physical function, physical role, body pain, general health, vitality, social function, emotional role, and mental health. Results: When comparing the evaluations between the contexts with and without a pandemic, a decrease in the quality of life was observed in the vitality dimensions (p = 0,004), social function (p = 0,001), emotional role (p = 0,001), health mental (p = 0,003) and general health (p = 0,001). The most altered dimensions were emotional role and general health, which decreased by 39,5 percent and 21,0 percent, respectively. Conclusions: This study determined that the health-related quality of life of young adults is diminished in context of quarantine by COVID-19, mainly in the psychological and social dimensions(AU)

ABSTRACT

Background: Upper limb (UL) function is compromised in university students due to prolonged academic activities and excessive use of electronic devices. However, it is unknown whether this relationship was affected by the COVID-19 pandemic situation. Aim: To determine the risk factors associated with reduced UL functionality in university students in a pandemic situation due to COVID-19. Material and Methods: Cross-sectional study that included 621 university students from the northern, central and southern areas of Chile. Physical variables, musculoskeletal, anthropometric and sociodemographic history were evaluated through self-reported questionnaires. Results: The factors with the higher association with a lower UL functionality were pain (Odds ratio (OR) = 17.6; 95% confidence intervals (CI) = 5.2-60; p < 0.01) and injury (OR = 10.4; 95% CI = 3.9-28.3; p < .001). Also, a low weight (OR = 10.5; 95% CI = 2.2-49.6; p < 0.01) and a quarantine lasting for five or more weeks (OR = 9.1; 95% CI = 1,1-77.2; p = 0.043) were considered risk factors. The lower probability was observed in male participants (OR = 0.2; 95% CI = 0.1-0.51; p < 0.01) and in those with a moderate/high muscular condition (OR = 0.3; 95% CI = 0.1-0.9; p = 0.031. Conclusions: The identification of these modifiable risk factors can help to implement preventive or rehabilitative actions at home or universities.

ABSTRACT

SUMMARY: The appropriate dosage of resistance training could promote physical and physiological adaptations and decrease injuries. The aim of the study was to analyze the effects of the different intra-set rest after eight weeks of resistance training on morphological variables, maximal strength, and jump performance in physically active university students. Twenty-five students (15 men and 10 women) were randomized by sex and distributed in Control Group (CG) (n=8) with rest only at the end of the series; Experimental Group 1 (EG1) (n=9) with an intra-set rest of 30 s, and Experimental Group 2 (EG2) (n=8) with four intra-set rest of 10 s. Morphological variables [body weight, bipedal height, body mass index (BMI), fat mass and muscle mass], maximum upper body strength (bench press and military press), lower body strength [parallel squat (45°) and deadlift], as well as countermovement jump (CMJ) were measured. All three groups obtained a significant increase (p0.05); thereby, there is an equivalent increase in muscle mass, maximal strength, jump performance, and a fat mass reduction.


RESUMEN: La dosificación adecuada de ejercicios de resistencia muscular permite favorecer adaptaciones físicas y fisiológicas, y reducir lesiones. El objetivo de este estudio fue analizar los efectos de distintos tiempos de descanso intra-serie luego de ocho semanas de ejercicios de resistencia muscular sobre variables morfológicas, fuerza máxima y saltabilidad en estudiantes universitarios físicamente activos. Veinticinco estudiantes (15 hombres y 10 mujeres) fueron aleatorizados por sexo y distribuidos en: grupo control (GC) (n=8) con descanso sólo al final de la serie; grupo experimental 1 (GE1) (n=9) con un descanso intra-serie de 30 s y grupo experimental 2 (GE2) (n=8) con cuatro descansos intra-serie de 10 s. Se midieron variables morfológicas [peso corporal, estatura bípeda, índice de masa corporal (IMC), masa adiposa y masa muscular], fuerza máxima del tren superior (press de banco plano y press militar) e inferior [sentadilla paralela (45°) y peso muerto] y saltabilidad con el salto contramovimiento (CMJ). Se obtuvo un aumento significativo (p<0,01) del peso corporal e IMC y, una reducción significativa (p<0,01) de la masa adiposa en los tres grupos. La masa muscular aumentó significativamente (p<0,01) en el GC y GE1. La fuerza máxima del tren superior e inferior aumentaron significativamente (p<0,05) en los tres grupos y para todos los ejercicios, mientras que el CMJ aumentó significativamente en el GC y GE1. No existen diferencias significativas entre distintos tiempos de descanso intra-serie cuando se utiliza el mismo volumen, intensidad y descanso total durante las series de ejercicios, logrando un aumento equivalente en masa muscular, fuerza máxima, saltabilidad y reducción de la masa adiposa.

ABSTRACT

Introducción: El envejecimiento se relaciona con mayor prevalencia de fragilidad y deterioro en la calidad de vida. Además, existe pérdida de la autonomía, lo que aumenta la institucionalización. Objetivo: Determinar los efectos de un programa de entrenamiento físico multicomponente, sobre la fragilidad y la calidad de vida de adultos mayores institucionalizados. Metodología: Estudio preexperimental, longitudinal, que evaluó 28 adultos mayores institucionalizados (17 mujeres y 11 hombres). La muestra fue seleccionada mediante un criterio no probabilístico intencionado. Se realizó un programa de entrenamineto multicomponente (resistencia aeróbica, fuerza muscular, equilibrio y flexibilidad) durante 6 semanas. Antes y después se evaluó la fragilidad en base a la escala de fenotipo propuesta por Fried y la calidad de vida con el cuestionario World Health Organization Quality of Life - Older Adults (WHOQoL-OLD). Se aplicó la prueba t de Student para realizar las comparaciones y se calculó el tamaño del efecto. Se utilizó un nivel alfa de 0,05. Resultados: Los adultos mayores mostaron mejoras significativas en el índice de fragilidad (p = 0,007; d = 0,36). La calidad de vida mostró cambios estadísticamente significativos en las dimensiones, Actividades pasadas, presentes y futuras (p = 0,018; d = 0,53); Participación social (p = 0,003; d = 0,53) e Intimidad (p = 0,005; d = 0,36), luego de realizar un programa de ejercicios multicomponente. La calidad de vida global de los participantes también mostró cambios significativos (p = 0,007; d = 0,65). Conclusión: Un programa de entrenamiento fisico multicomponente de 6 semanas de duración mejoró la fragilidad y calidad de vida de adultos mayores institucionalizados(AU)


Introduction: Aging is related to a higher prevalence of frailty and deterioration in quality of life. There is also a loss of autonomy, which increases institutionalization. Objective: To determine the effects of a multicomponent physical training program, on frailty and quality of life in institutionalized older adults. Methodology: Pre-experimental, longitudinal study that evaluated 28 institutionalized older adults (17 women and 11 men). The sample was selected using an intentional non-probabilistic criterion. A multicomponent training program (aerobic resistance, muscular strength, balance and flexibility) was carried out for 6 weeks, before and after the fragility was evaluated based on the phenotype scale proposed by Fried and the quality of life with the World Health Organization questionnaire Quality of Life - Older Adults (WHOQoL-OLD). The Student's t-test was applied to make the comparisons and the effect size was calculated. An alpha level of 0.05 was used. Results: After participating in the multicomponent exercise program, older adults showed significant improvements in the frailty index (p = 0.007; d = 0.36). The quality of life showed statistically significant changes in the dimensions Past, present and future activities (p = 0.018; d = 0.53), Social Participation (p = 0.003; d = 0.53) and Intimacy (p = 0.005; d = 0.36) after completing a multi-component exercise program. The overall quality of life of the participants also showed significant changes (p = 0.007; d = 0.65). Conclusion: A 6-week multi-component physical training program improved the frailty and quality of life of institutionalized older adults(AU)

ABSTRACT

ABSTRACT Background: Aging causes an involution of anthropometric and health indices that can affect physical fitness. Aim: To determine the influence of anthropometric and health indices on the physical fitness of elderly women. Material and Methods: Anthropometric parameters, serum lipids, blood glucose and physical fitness evaluated using Senior Fitness Test, were assessed in 140 women aged 70 ± 5 years. The association between parameters was analyzed using Pearson's correlation coefficient and multiple regression models. Results: In the regression models serum lipids and the suprailiac skinfold were significant predictors of the up and go test (R2= 0.48). HDL cholesterol and the level of physical activity were predictors of the two minutes step test (R2= 0.31). Serum lipids, suprailiac skinfold and age were predictors of the back-scratch test (R2= 0.41). Fasting blood glucose and HDL cholesterol were predictors of the chair sit and reach test (R2= 0.24). Serum lipids and body mass index were predictors of the arm curl test (R2= 0.37). Body mass index and serum lipids were predictors of the chair stand test (R2= 0.49). Conclusions: Anthropometric variables, serum lipid levels and blood glucose were predictors of different physical fitness parameters in these women.


Antecedentes: El envejecimiento causa involución de indices antropométricos y de salud, los cuales pueden afectar la condición física. Objetivo: Determinar la influencia de indices antropométricos y de salud sobre la condición física de mujeres mayores. Material y Métodos: Se evaluaron parámetros antropométricos, lípidos séricos y la condición física mediante el "senior fitness test" en 140 mujeres de 70 ± 5 años. La asociación entre variables se evaluó mediante correlaciones simples y modelos de regresión múltiple. Resultados: En los modelos de regresión múltiple, los lípidos séricos y pliegue suprailíaco fueron predictores significativos de la prueba de levantarse, caminar y volver a sentarse (R2 = 0,48). El colesterol HDL y el nivel de actividad física fueron predictores de la prueba de dos minutos de marcha (R2 = 0,310). Los lípidos séricos, el pliegue suprailíaco y la edad fueron predictores de la prueba de juntar las manos tras la espalda (R2 = 0,41). La glicemia en ayunas y el colesterol HDL fueron predictores de la prueba de flexión del tronco en silla (R2 = 0,24). El índice de masa corporal y los lípidos séricos fueron predictores de la prueba de flexo-extensión de codo (R2= 0,37). El índice de masa corporal y los lípidos séricos fueron predictores de la prueba de sentarse y levantarse de una silla (R2 = 0,49). Conclusiones: Las variables antropométricas, los lípidos séricos y la glicemia fueron predictores de diversas pruebas de capacidad física en mujeres mayores.

ABSTRACT

Background: The quarantine and social distancing implemented during COVID 19 pandemic may hamper the quality of life of the population. Aim: To determine the factors associated with a low quality of life during COVID 19 quarantine in Chilean adults. Material and Methods: The SF-36 survey about quality of life was answered by 1,082 Chilean adults aged between 18 and 60 years, who were quarantined by the COVID-19 health alert. Other variables studied were sociodemographic background, nutritional status, lifestyles, level of physical activity, sedentary behavior and sleep hours. Risk factors associated with low quality of life were identified by logistic regression analysis for each of the 8 dimensions evaluated in the SF-36 questionnaire. Results: The factors that increased the probability of having a lower general health perception were being female (Odds ratio (OR) = 1.29; p = 0.05), being physically inactive (OR = 2.76 p < 0.01), unhealthy hours of sleep (OR = 1.58, p < 0.01), smoking (OR = 1.59, p < 0.01) and eating junk food (OR = 2.26; p < 0.01). For the other dimensions of quality of life, the most frequently repeated factors were being female, junk food consumption, and being physically inactive and sedentary. Conclusions: There are factors associated with a low quality of life during the quarantine of the COVID-19 pandemic in the Chilean population. Their identification could reinforce remedial actions at the government level to benefit the health of the population during this health emergency.

ABSTRACT

Abstract Introduction: Physical activity is important for achieving healthy aging. Objective: To analyze changes in anthropometric parameters and physical fitness among Chilean older adults after participating in a 16-week physical activity program and to evaluate whether there were differences in relation to their baseline nutritional status or not. Materials and methods: Pre-experimental quantitative study. The study population consisted of 176 older adults (155 women and 21 men) distributed in three groups: normal weight (n = 56), overweight (n=67) and obese (n = 53). The following variables were evaluated: body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHR) and physical fitness. Results: Significant decreases between pre- and post-measurements were found for WC (p<0.001), BMI (p=0.015), and WHR (p<0.001). Improvements were observed in the following tests: chair stand (p<0.001), arm curl (p<0.001), 2-min step (p<0.001), chair sit-&-reach (p=0.018) and back scratch (p=0.014). Regarding BMI, significant changes were observed between normal weight vs. overweight participants (p=0.001) and between normal weight vs. obese participants (p=0.001). Conclusion: Older adult participants that regularly attended the physical activity program were able to reduce their WC, BMI and WHR, and also improved their physical-functional performance on the chair stand, arm curl, 2-min step, chair sit-&-reach and back scratch tests. In addition, anthropometric parameters and physical fitness also improved regardless of their baseline nutritional status.

ABSTRACT

RESUMEN El sobrepeso y obesidad infantil se han convertido en un problema de salud a nivel mundial. A medida que la incidencia y la gravedad del sobrepeso y la obesidad siguen aumentando en niños y niñas, la determinación de los efectos fisiológicos y consecuencias funcionales se hacen cada vez más importantes. Estas últimas han sido las menos estudiadas, subestimándose su impacto sobre el desempeño motor. El control postural juega un papel importante en el desarrollo motor del niño, ya que es necesario para lograr nuevas posturas en etapas tempranas de la vida y para la adquisición de habilidades motoras más complejas. Esta revisión revela que los niños y niñas con sobrepeso y obesidad presentan un déficit del control postural evidenciado principalmente a partir de evaluaciones estáticas en una plataforma de fuerza y el análisis de la excursión del centro de presión. Entre las causas de la alteración del equilibrio en los niños y niñas con exceso de peso destaca la interacción de factores mecánicos, sensoriales y neuromusculares. Un pobre control postural provocaría un aumento del riesgo de caídas y lesiones, retraso en el desarrollo motor, limitaciones de la movilidad, alteración de la marcha y dificultad para la adquisición de otras habilidades motoras.


ABSTRACT Overweight and childhood obesity have become a global health problem. As the incidence and severity of overweight and obesity in children continue to rise, determining the physiological effects and functional consequences are becoming increasingly important. The latter have been the least studied, underestimating its impact on motor performance. Postural control plays an important role in the motor development of the child, as it is necessary to achieve new postures in the early stages of life and to acquire more complex motor skills. This review reveals that children with overweight and obesity have a deficit of postural control evidenced mainly from static assessments in a force platform and the analysis of the excursion of the center of pressure. Among the causes of impaired balance in overweight children is the interaction of mechanical, sensory and neuromuscular factors. Poor postural control would lead to an increased risk of falls and injuries, delayed motor development, limited mobility, impaired gait, and difficulty in acquiring other motor skills.

El tamaño del efecto se calculó con la d de Cohen. Resultados: Los universitarios inactivos presentaron mayor índice de masa corporal (IMC) (p=0,041), en contraste, los universitarios activos mostraron una puntuación significativamente mayor que los inactivos en CV global (p=0,002; d=0,67), CV en salud (p=0,013; d=0,50), dominio físico (p=0,038; d=0,43), psicológico (p=0,003; d=0,63) y medio ambiente (p=0,001; d=0,80). Conclusiones: Los estudiantes universitarios activos (moderado/alto nivel de AF) presentan mejor CV global y en salud, además presentan mejor puntuación en CV en los dominios físico, psicológico medio ambiente al compararlos con estudiantes inactivos.


Introduction: University students are susceptible to unhealthy lifestyles, which could deteriorate their quality of life (QL). Objective: To compare the QL in university students who have different levels of physical activity (PA). Materials and methods: A descriptive, cross-sectional study that included 126 university students of both sexes from Health, Education and Engineering programs of three universities in Talca (Chile). The QL was assessed through the WHOQOL-BREF questionnaire. A student's t-test of independent samples was used to compare both the domains of the QL and the baseline characteristics between the groups. The effect size was calculated with Cohen's d. Results: Inactive university students had a higher body mass index (BMI) (p=0.041). In contrast, active students showed significantly higher scores than inactive ones in overall QL (p=0.002; d=0.67), health QL (p=0.013; d=0.50), physical domain (0.038; d=0.43), psychological domain (p=0.003; d=0.63) and environment domain (p=0.001; d=0.80). Conclusions: Active university students (with moderate and high PA levels) have better overall and health QL. They also have better QL scores in the physical, psychological and environmental domains when compared to inactive students.

ABSTRACT

Resumen La electromiografía (EMG) se define como la disciplina relacionada con la detección, análisis y uso de la señal eléctrica que se genera cuando un músculo se contrae. La señal electromiográfica se basa en los potenciales de acción de la fibra muscular que resultan de los procesos de despolarización y repolarización en la membrana celular. Entre las diversas formas de análisis de la señal electromiográfica destacan dos parámetros principales: la amplitud y frecuencia de la señal. A partir de la amplitud se pueden determinar el nivel de activación del músculo (porcentaje de activación) y el tiempo que demora un músculo en activarse (latencia). Por su parte, con el análisis de la frecuencia de la señal electromiográfica se puede determinar el nivel de fatiga muscular desde el punto de vista electrofisiológico. En condiciones de lesión y/o patológicas se ha demostrado que los patrones neuromusculares normales de movimiento se ven alterados en sus niveles de activación, orden de reclutamiento, latencias musculares y/o niveles de fatiga. Por lo tanto, el uso de la EMG en las ciencias de la rehabilitación ha contribuido a comprender los patrones neuromusculares utilizados en la ejecución de distintos gestos motores, y al entendimiento de las posibles causas y consecuencias de una lesión y/o disfunción sobre el comportamiento electrofisiológico del músculo. Esto ha ayudado a orientar la planificación de los programas de entrenamiento muscular para una lesión y/o patología especifica durante el proceso de rehabilitación.


Abstract Electromyography (EMG) is defined as the discipline related to the detection, analysis and use of the electrical signal that is generated when a muscle contracts. The electromyographic signal is based on the action potentials of the muscle fiber that result from the processes of depolarization and repolarization in the cell membrane. Two main parameters stand out among the different forms of analysis of the electromyographic signal: The amplitude and frequency of the signal. From the amplitude the level of muscle activation (percentage of activation) can be determined and the time it takes a muscle to activate (latency). On the other hand, with analysis of the frequency of the electromyographic signal, the level of muscular fatigue can be determined from the electrophysiological point of view. In injury and/or pathological conditions it has been shown that normal neuromuscular patterns of movement have been altered, either in their levels of activation, recruitment order, muscle latencies and/or levels of fatigue. Therefore, the use of EMG in rehabilitation sciences, have contributed to the understanding of the neuromuscular patterns used in the execution of different motor gestures and to the understanding of the possible causes and consequences of an injury and/or dysfunction on the behavior electrophysiology of the muscle. This has helped to guide the planning of muscular training programs for a specific injury and/or pathology during the rehabilitation process.

ABSTRACT

Background:: The Senior Fitness Test (SFT) is frequently used to assess physical fitness and functional independence in older people. Aim: To establish reference values for the SFT in Chilean physically active older women according to age ranges. Material and Methods: Cross-sectional study that included 1048 Chilean women aged between 60 and 85 years. Chair stand (CS), arm curl (AC), two-min walk (2 min), chair sit-and-reach (CSr), back scratch (BS), and timed up-and-go test (TUG) were evaluated. The reference values are presented in percentiles (p5, p10, p25, p50, p75, p90 and p95) and are distributed age intervals (60-64, 65-69, 70-74, 75-79 and ≥ 80 years). Results: There was a decrease in strength (CS and AC), aerobic resistance (2 min) and flexibility (CSr and BS) along with age, whereas the time required to perform the timed up and go increased along with age. Conclusions: Physically active older women show a deterioration in physical fitness along with age. These women have higher reference values in CS, AC, 2 min and CSr, and lower in BS and TUG, than those reported abroad for the SFT.

ABSTRACT

Background: University students are considered a vulnerable group due to their adoption of unhealthy diets and lifestyles. Aim: To determine the main risk factors associated with low level of physical activity and excess body weight in university students. Material and Methods: This cross-sectional study included 358 university students from Talca, (53% female). Sociodemographic, academic, health, lifestyle, nutritional status, physical activity and sedentary behavior variables were analyzed by logistic regression. Results: Men were more likely to present excess body weight than women (Odds ratio (OR): 2.16 [95% CI: 1.17-4.01], p = 0.01). Similarly, those with low level of physical activity (OR: 2.13 [95% CI: 1.10-414], p = 0.03), musculoskeletal injuries (OR: 2.43 [95% CI: 1.09-6.34], p = 0.05) and smokers (OR: 2.09 [95% CI: 1.05-4.14], p = 0.04) were more likely to have excess body weight. Individuals with excess body weight (OR: 2.94 [95% CI: 1.31-6.61], p < 0.01), high sedentary behaviors (OR: 2.01 [95% CI: 1.04-4.55], p = 0.04), those who spent more than 7 hours per week studying (OR: 2.11 [95% CI: 1.06-4.66], p = 0.04), and those with presence of musculoskeletal injuries (OR: 1.49 [95% CI: 1.06- 3.66], p = 0.04) were more likely to be physically inactive. In addition, men were 73% less likely to have low physical activity levels compared to women (OR: 0.27 [95% CI: 0.11-0.56], p < 0.01). Conclusions: University students have several modifiable risk factors associated with low levels of physical activity and excess weight. Healthy lifestyles promotion should modify these risk behaviors.
