Effects of Aquatic Exercise on Physical Performance in Older Adults: A Systematic Review and Meta-Analysis.

This systematic review aimed to evaluate the effects of aquatic exercise on physical performance in older adults. Databases were searched up to July 2021. Randomized controlled trials were screened by two reviewers, who extracted data and assessed study quality. Ten randomized controlled trials (603 participants) were included. Compared with nonexercising controls, aquatic exercise probably improved lower limb muscle power (30-s Chair Stand Test; mean difference 4.75 repetitions; 95% confidence interval [0.07, 9.42]; I2 = 99%; 251 participants; very low-quality evidence). When comparing aquatic exercise with land exercise, there is probably no superiority in favor of either intervention on dynamic balance (Timed Up and Go Test; mean difference -0.12 s; 95% confidence interval [-0.37, 0.12]; I2 = 3%; 244 participants; very low-quality evidence).

Implementation processes of social network interventions for physical activity and sedentary behavior among children and adolescents: a scoping review.

BACKGROUND: The characteristics of the implementation process of interventions are essential for bridging the gap between research and practice. This scoping review aims to identify the implementation process of social network interventions (SNI) to address physical activity and sedentary behaviors in children and adolescents. METHODS: The scoping review was conducted adhering to the established guidelines. The search was carried out in the ERIC, EBSCO, EMBASE, SCOPUS, and Lilacs databases in April 2023. Social network intervention studies in children and adolescents were included, addressing physical activity or sedentary behaviors. Replicability (TIDieR), applicability (PRECIS-2), and generalizability (RE-AIM) were the explored components of the implementation process. Each component was quantitatively and separately analyzed. Then, a qualitative integration was carried out using a narrative method. RESULTS: Most SNI were theoretically framed on the self-determination theory, used social influence as a social mechanism, and used the individual typology of network intervention. Overall, SNI had strong replicability, tended to be pragmatic, and three RE-AIM domains (reach, adoption (staff), and implementation) showed an acceptable level of the generalizability of findings. CONCLUSIONS: The analyzed SNI for physical activity and sedentary behaviors in adolescents tended to be reported with high replicability and were conducted pragmatically, i.e., with very similar conditions to real settings. The RE-AIM domains of reach, adoption (staff), and implementation support the generalizability of SNI. Some domains of the principles of implementation strategies of SNI had acceptable external validity (actor, action targets, temporality, dose, and theoretical justification).

Handgrip strength in older adults from Antioquia-Colombia and comparison of cutoff points for dynapenia.

Handgrip strength is a predictor of functional impairment and presence of morbimortality in older adults. However, appropriate reference values and cutoff points are required for its optimal use. This study describes handgrip characteristics in the older adult population of Antioquia-Colombia and compares the dynapenia handgrip cutoffs proposed for Colombians with international criteria. A cross-sectional study including 1592 older adults was done. Dynapenia prevalence by handgrip was analyzed using the following cutoffs: European Consensus of Sarcopenia (2018), Asian Working Group for Sarcopenia (2019), Chilean (2018), and Colombian (2019). Handgrip strength significantly decreased with aging, showing a positive and strong association with functional and health parameters. The highest prevalence of dynapenia was found with the Asian Consensus cutoffs (26.1%) and the lowest with the Colombian cutoffs (0.8%). Low agreement was found between the Colombian cutoffs with the European Consensus (kappa = 0.059; p < 0.001), the Asian Consensus (kappa = 0.039; p < 0.001) and the Chilean proposal (kappa = 0.053; p < 0.001). Dynapenia using the Chilean, European, and Asian cutoffs was associated with physical inactivity, presence of multimorbidity, slow gait speed, nutritional risk, and low calf circumference. Meanwhile, the Colombian cutoffs was only associated with slow gait speed and low calf circumference. The handgrip cutoffs proposed for Colombians seems to underestimate the dynapenia prevalence in older people from Antioquia. Furthermore, these cutoff points did not show associations with relevant functional and health parameters. The handgrip cutoffs proposed for Colombians should be used with caution.

Factores asociados al cumplimiento de las recomendaciones de actividad física de la Organización Mundial de la Salud, en los adultos de Antioquia - Colombia

Objetivo: Describir los factores asociados al cumplimiento de las recomendaciones de actividad física (AF) de la Organización Mundial de la Salud, en los adultos de Antioquia. Metodología: Se realizó un análisis transversal de la base de datos del "Perfil alimentario y nutricional de Antioquia". La AF se indagó en 2757 adultos (18-64 años), utilizando el "Cuestionario mundial de actividad física" de la Organización Mundial de la Salud. Se hicieron análisis bivariados y multivariados, explorando la relación de variables socioeconómicas, demográficas y de estado nutricional, con el cumplimiento de las recomendaciones de AF. Resultados: Se observó una mayor prevalencia de cumplimiento de las recomendaciones de AF en hombres que mujeres (60,8 vs. 48,0 %; p< 0,001) y en adultos jóvenes (18-29 años) que en mayores de 29 años (66,8 vs. 49,3 %; p< 0,001). Además, se presentó más alta proporción de cumplimiento de las recomendaciones de AF en personas de mayor estrato socioeconómico, mayor nivel educativo y residentes del área urbana. Ser mujer, pertenecer al estrato socioeconómico 1, poseer secundaria o un nivel de educación inferior, y tener como ocupación oficios del hogar se asociaron con una probabilidad menor de cumplir las recomendaciones de AF; por el contrario, ser una persona joven se asocia con un mayor cumplimiento. Conclusión: Son evidentes las desigualdades en el cumplimiento de las recomendaciones de AF por los adultos de Antioquia. Se deben priorizar las mujeres, las personas mayores de 30 años, de bajo estrato socioeconómico y de bajo nivel educativo en los planes y programas orientados a promover la práctica de la AF en el departamento.

Objective: To describe the factors associated with adherence to the World Health Organization's physical activity (PA) recommendations in adults from Antioquia-Colombia. Methodology: A cross-sectional analysis of the database of the "Food and nutritional Profile of Antioquia" was carried out. PA was inquired in 2,757 adults (18-64-year-olds), using the World Health Organization's "Global Physical Activity Questionnaire". Bivariate and multivariate analyses were performed, exploring the relationship between socioeconomic, demographic and nutritional status variables and adherence to PA recommendations. Results: A higher prevalence of adherence to PA recommendations was observed in men compared to women (60.8 vs. 48.0 %; p < 0.001) and in young adults (18-29) compared to in adults older than 29 years of age (66.8 vs. 49.3 %; p < 0.001). In addition, adherence to PA recommendations was higher in people with high socioeconomic status, a high educational level and residents of urban areas. Being a woman, belonging to socioeconomic stratum 1, having high school or a lower level of education, and having as an occupation household chores were associated with a lower probability of adherence to PA recommendations; while being young is associated with greater adherence. Conclusion: Inequalities in adherence to FA recommendations by adults in Antioquia are evident. Women and people over 30 years of age with low socioeconomic status and low educational levels should be prioritized in plans and programs aimed at promoting the practice of PA in the department.

Objetivo: Descrever os fatores associados ao cumprimento das recomendações de atividade física (AF) da Organização Mundial da Saúde, nos adultos de Antioquia. Metodologia: Realizou-se uma análise transversal da base de dados do "Perfil alimentar e nutricional de Antioquia". A AF indagou-se em 2757 adultos (18-64 anos), usando o "Questionário mundial de atividade física" da Organização Mundial da Saúde. Fizeram-se análises bivariadas e multivariadas, explorando a relação de variáveis socioeconômicas, demográficas e de estado nutricional, com o cumprimento das recomendações de AF. Resultados: Observou-se uma maior prevalência de cumprimento das recomendações de AF em homens do que em mulheres (60,8 vs. 48,0%; p>0,001) e em jovens adultos (18-29 anos) do que em maiores de 29 anos (66,8 vs. 49,3%; p>0,001). Além disso, apresentou-se proporção mais alta de cumprimento das recomendações de AF em pessoas de mais alto estrato socioeconômico, maior nível educativo e residentes da área urbana. Ser mulher, pertencer ao estrato socioeconômico 1, possuir grau de secundária ou um nível inferior de educação e ter como ocupação trabalhos do lar associaram-se com uma probabilidade menor de cumprir as recomendações de AF; pelo contrário, ser uma pessoa jovem associa-se com um maior cumprimento. Conclusão: São evidentes as desigualdades no cumprimento das recomendações de AF pelos adultos de Antioquia. Devem-se priorizar as mulheres, as pessoas maiores de 30 anos, de estrato socioeconômico baixo e de baixo nível educativo nos planos e programas orientados a promover a prática da AF no departamento.

Componentes del síndrome metabólico y factores de riesgo asociados en estudiantes de un programa de nutrición

RESUMEN La población universitaria presenta cambios en su estilo de vida, que se refleja en su composición corporal, y alteraciones metabólicas. Los estudiantes del área de la salud son futuros promotores de estilos de vida saludables. El objetivo de este trabajo fue identificar la frecuencia del Síndrome metabólico (SM) y sus componentes en los estudiantes del programa de Nutrición y Dietética. Noventa estudiantes de 18 a 25 años, en quienes se evaluaron los componentes del SM, la actividad física por acelerometría, el consumo de alcohol mediante el cuestionario Audit, tabaquismo y horas de sueño por el método Pittsburgh. Las prevalencias encontradas fueron: SM 1,1%, circunferencia de cintura elevada 4,5%, triglicéridos altos 11%, HDL bajos 32%, presión arterial elevada 1,1%. Se encontró que 73% cumplían con las recomendaciones de actividad física recomendadas por la OMS. Sin embargo, el 100% de los estudiantes pasaron más de 9 horas sedentarias por día, el 6,7% presentaron un consumo de alcohol catalogado como perjudicial, 19% estuvieron expuestos al humo o eran fumadores, y el 63,3% se consideraron como malos dormidores. No hubo asociación entre las variables del estilo de vida con los componentes del SM. En conclusión, los triglicéridos altos y las HDL bajas, el sedentarismo y la baja calidad de sueño son variables importantes para tener en consideración en programas de intervención con la finalidad de ser nutricionistas coherentes con la profesión.

ABSTRACT Changes to body composition and metabolic functions occur in the university population due to lifestyle choices. Students in the health programs are expected to fulfill a fundamental role in promoting healthy lifestyles. The objective of this work was to identify the frequency of Metabolic Syndrome (MS) and its components among students of a Nutrition and Dietetics program. Ninety students between 18 and 21 years old were evaluated for each of the components of the MS, physical activity by accelerometry, alcohol consumption by Audit questionnaire, smoking, and hours of sleep by Pittsburgh method. The prevalence found were: MS 1.1%, high waist circumference 4.5%, high triglycerides 11%, low HDL 32%, high blood pressure 1.1%. Regarding variables related to lifestyle habits, 73% complied with physical activity recommendations recommended by the WHO. However, 100% of the students were sedentary more than 9 hours per day, 6.7% had alcohol consumption classified as harmful, 19% were exposed to smoke or were smokers, and 63.3% were considered bad sleepers. There was no association between lifestyle variables and the MS components. In conclusion, high triglycerides, low HDL, sedentary lifestyle, and low sleep quality are crucial variables to consider in intervention programs aimed at training nutritionist, in keeping with the profession.

Relationship of Body Composition with the Strength and Functional Capacity of People over 70 Years.

BACKGROUND: Aging is a multifactorial physiological phenomenon, in which a series of changes in the body composition occur, such as a decrease in muscle mass and bone mineral density and an increase in fat mass. This study aimed to determine the relationship of muscle mass, osteoporosis, and obesity with the strength and functional capacity of non-dependent people over 70 years of age. METHODS: A cross-sectional study was designed, whose study population was all people aged over 70 years, living independently and attending academic and recreational programs. Muscle strength and functional capacity of the participants were assessed by isometric exercises of lower and upper limbs and by four tests taken from the Senior Fitness Test, respectively. Bone mineral density, total mass, fat mass, total lean mass, arms lean mass, legs lean mass, and appendicular lean mass (ALM) was calculated by dual energy X-ray absorptiometry. Differences in muscle strength and functional capacity, according to the sex, muscle mass, mineral bone density and fat mass, were measured by χ2 test, independent samples Student's t-test, analysis of covariance and a 2-factor analysis of covariance; Results: 143 subjects were included in the study group. Men and women with an adequate amount of ALM adjusted for body mass index (BMI) had a maximal dynamic biceps strength in a single repetition, a maximal isometric leg extension strength, a maximal dynamic leg extension strength in a single repetition, a maximum right hand grip strength and maximum hand grip strength (the highest). Significantly higher values were observed in the maximal isometric biceps' strength in men with osteoporosis. Obese men had less isometric strength in the biceps and took longer to perform the chair stand test; Conclusions: Men and women with an adequate amount of ALM adjusted for BMI obtained better results in tests of muscle strength and functional capacity. However, osteoporosis and obesity are not related to these parameters.

Resumen Objetivo: Evaluar la validez concurrente y la confiabilidad test-retest del Global Physical Activity Questionnaire (GPAQ) y el International Physical Activity Questionnaire (IPAQ, versión corta) en una comunidad universitaria. Metodología: Un total de 76 personas de la Universidad de Antioquia, Medellín (Colombia), con edades entre 18 y 44 años, portaron un acelerómetro (ActiGraph GT3X+) durante siete días y posteriormente diligenciaron los dos cuestionarios; estos se repitieron una semana después. La validez y la confiabilidad para evaluar el gasto energético (GE) y el tiempo sedentario (TS) se determinó con el coeficiente de correlación intraclase (CCI); la concordancia para clasificar el nivel de actividad física (NAF) se evaluó con el índice de Kappa ponderado (IKp). Resultados: Para medir el GE, el IPAQ mostró una validez "moderada" (CCI=0,434, IC95%=0,231-0,600; p<0,001) y el GPAQ "pobre" (CCI= 0,335, IC95%=0,123-0,519; p<0,001); para el TS, la validez de ambos cuestionarios fue "pobre" (IPAQ: CCI=0,234, IC95%=0,011-0,435, p<0,020; GPAQ: CCI=0,231, IC95%=0,009-0,432, p<0,021). Para clasificar el NAF (bajo, moderado o alto), ambos cuestionarios mostraron concordancias "bajas" (IPAQ: IKp=0,298, p=0,001; GPAQ: IKp=0,137, p=0,119). La confiabilidad del GPAQ para evaluar el GE fue "buena/excelente" (CCI=0,838; IC95%=0,754-0,895; p<0,001) y del IPAQ fue "moderada" (CCI=0,655; IC95%=0,505-0,766; p<0,001). La confiabilidad para el TS fue "moderada" en ambos instrumentos (IPAQ: CCI=0,716; IC95%=0,583-0,811; p<0,001; GPAQ: CCI=0,736; IC95%=0,613-0,824; p<0,001). Conclusiones: Los cuestionarios mostraron poca validez para la medición del NAF y del TS. Sin embargo, ambos instrumentos presentaron una buena confiabilidad para la medición de las variables estudiadas. No se recomienda el uso de los cuestionarios para la población estudiada.

Abstract Objective: Evaluate the concurrent validity and test-retest reliability of the Global Physical Activity Questionnaire (GPAQ) and the International Physical Activity Questionnaire (IPAQ, short version) in a university community. Methodology: A total of 76 people from the University of Antioquia, Medellín (Colombia), aged between 18 and 44, carried an accelerometer (ActiGraph GT3X +) for seven days and subsequently filled out the two questionnaires; these were repeated a week later. The validity and reliability for assessing energy expenditure (EE) and sedentary time (ST) was determined with the intraclass correlation coefficient (ICC); concordance to classify the physical activity level (PAL) was evaluated with the weighted Kappa index (wKI). Results: To measure the EE , IPAQ showed a "moderate" validity (ICC = 0.434, CI 95% = 0.231-0.600; p <0.001) and the "poor" QPAQ (ICC = 0.335, CI 95% = 0.123-0.519; p <0.001); for ST , the validity of both questionnaires was "poor" (IPAQ : ICC = 0.234, CI 95% = 0.011-0.435, p <0.020; GPAQ: ICC = 0.231, CI 95% = 0.009-0.432, p <0.021). To classify the PAL (low, moderate or high), both questionnaires showed "low" concordance (IPAQ: wKI = 0.298, p = 0.001; GQAP: wKI = 0.137, p = 0.119). The reliability of the GPAQ for assessing EE was "good/excellent" (ICC = 0.838; CI 95% = 0.754-0.895; p <0.001) and the IPAQ was "moderate" (ICC = 0.655; IC 95% = 0.505-0.766 ; p <0.001). The reliability for ST was "moderate" in both instruments (IPAQ: ICC = 0.716; CI 95% = 0.583-0.811; p <0.001; GPAQ: ICC = 0.736; CI 95% = 0.613-0.824; p <0.001). Conclusions: The questionnaires showed little validity for measuring PAL and ST . However, both instruments presented good reliability for measuring the variables studied. The use of questionnaires for the population studied is not recommended.

Effects of high-intensity interval training compared to moderate-intensity continuous training on maximal oxygen consumption and blood pressure in healthy men: A randomized controlled trial / Efecto del entrenamiento con intervalos de gran intensidad comparado con el entrenamiento continuo de intensidad moderada en el consumo máximo de oxígeno y la presión arterial en hombres sanos: estudio clínico aleatorio

INTRODUCTION: Aerobic exercise generates increased cardiorespiratory fitness, which results in a protective factor for cardiovascular disease. High-intensity interval training (HIIT) might produce higher increases on cardiorespiratory fitness in comparison with moderate-intensity continuous training (MICT); however, current evidence is not conclusive. OBJECTIVE: To compare the effects of a low-volume HIIT and a MICT on maximal oxygen consumption (VO2max), systolic blood pressure, and diastolic blood pressure during eight weeks in healthy men between 18 and 44 years of age. MATERIALS AND METHODS: We conducted a randomized controlled trial. Forty-four volunteers were randomized to HIIT (n=22) or MICT (n=22). Both groups performed 24 sessions on a treadmill. The HIIT group completed 15 bouts of 30 seconds (90-95%, maximal heart rate, HRmax), while the MICT group completed 40 minutes of continuous exercise (65-75% HRmax).  Results: Intra-group analysis showed an increase in VO2max of 3.5 ml/kg/min [95% confidence interval (CI) 2.02 to 4.93; p=0.0001] in HIIT and 1.9 ml/kg/min (95% CI -0.98 to 4.82; p=0.18) in MICT. However, the difference between the two groups was not statistically significant (1.01 ml/kg/min. 95% CI -2.16 to 4.18, p=0.52). MICT generated a greater reduction in systolic blood pressure compared to HIIT (median 8 mm Hg; p<0.001). No statistically significant differences were found between the groups for DBP. CONCLUSIONS: Results indicated no significant change in VO2max with a low-volume HIIT protocol versus MICT after 24 sessions. In contrast, MICT provided a greater reduction in systolic blood pressure compared to HIIT. The study is registered as a clinical trial via clinicaltrials.gov with identifier number: NCT02288403.

Introducción. El ejercicio aeróbico incrementa la capacidad cardiorrespiratoria, considerada como factor de protección frente a enfermedades cardiovasculares. El entrenamiento con intervalos de gran intensidad (High Intensity Interval Training, HIIT) podría causar mayores incrementos en la capacidad cardiorrespiratoria comparado con el entrenamiento continuo de intensidad moderada, aunque la información actual no es concluyente. Objetivo. Comparar los efectos del entrenamiento con intervalos de gran intensidad de bajo volumen y del entrenamiento continuo de intensidad moderada, en el volumen máximo consumido de oxígeno (VO2max), la presión arterial sistólica y la presión arterial diastólica, durante ocho semanas en hombres sanos entre los 18 y los 44 años de edad. Materiales y métodos. Se hizo un ensayo clínico controlado con asignación al azar. Se incluyeron 44 voluntarios, 22 a entrenamiento con intervalos de gran intensidad y 22 a uno continuo de intensidad moderada. Ambos grupos hicieron 24 sesiones en tapiz rodante. El primer grupo completó 15 cargas de 30 segundos (90-95 % de la frecuencia cardiaca máxima y, el segundo hizo 40 minutos continuos (65-75 % de la frecuencia cardiaca máxima). Resultados. El análisis dentro de cada grupo mostró un aumento en el volumen máximo consumido de oxígeno de 3,5 ml/kg por minuto (intervalo de confianza, IC95% 2,02 a 4,93; p=0,0001) con el entrenamiento con intervalos de gran intensidad, y de 1,9 ml/kg por minuto (IC95% -0,98 a 4,82; p=0,18) con el continuo de intensidad moderada. Sin embargo, las diferencias entre grupos no fueron estadísticamente significativas (1,01 ml/kg por minuto; IC95% -2,16 a 4,18; p=0,52). El entrenamiento continuo de intensidad moderada generó una mayor reducción en la presión arterial sistólica, comparado con el de intervalos de gran intensidad (mediana: 8 mm Hg; p<0,001). Por último, no se hallaron diferencias estadísticamente significativas entre grupos en la presión arterial diastólica. Conclusiones. Los resultados no evidenciaron diferencias en el efecto sobre el VO2máx con un protocolo de entrenamiento con intervalos de gran intensidad de bajo volumen, en comparación con el continuo de intensidad moderada. Por el contrario, con este último, la reducción en la presión arterial sistólica fue mayor que con el de intervalos de gran intensidad. El estudio está registrado en clinicaltrials.gov, código: NCT02288403.

Sarcopenia in community-dwelling persons over 60 years of age from a northern spanish city: relationship between diagnostic criteria and association with the functional performance.

INTRODUCTION: Sarcopenia is a recognized problem in older people. Currently, its diagnosis goes beyond a simple loss of muscle mass. The aim of this study was to determine the frequency of sarcopenia, defined by the European Working Group on Sarcopenia in Older People (EWGSOP), in independent persons over 60 years of age from a northern Spanish city. In addition, this study compared the diagnostic criteria for sarcopenia and assessed the differences in functional performance according to them. METHODS: A cross-sectional study was carried out on 258 members of community centers of both genders. Body composition was assessed with dual-energy X-ray absorptiometry. Appendicular lean mass index (App LMI), hand grip strength (HGS), and 8 foot up-and-go test (8f-UG) were used to diagnose sarcopenia. RESULTS: The frequency of sarcopenia was 2.4% (n=6). In women, the App LMI was correlated with HGS (r= 0.164, p<0.05) and 8f­UG (r= -0.167, p<0.05), while in men, the App LMI was correlated with HGS (r=0.241, p<0.05) but not with 8f­UG (r= -0.173, p=0.117). The subjects with low HGS and low performance in the 8f­UG presented lower values in other functional outcomes than people with low App LMI (p<0.05). CONCLUSIONS: Using the EWGSOP definition, the frequency of sarcopenia was low in a group of individuals over 60 years of age from a northern Spanish city. In clinical practice, greater emphasis should be placed on the decrease in muscle strength and functional performance rather than on low muscle mass alone.

Introducción: La sarcopenia es un problema reconocido en la personas mayores. Actualmente, su diagnóstico va más allá de una simple pérdida de la masa muscular. El objetivo de este estudio fue determinar la frecuencia de sarcopenia definida por el European Working Group on Sarcopenia in Older People (EWGSOP), en personas mayores de 60 años con vida independiente de una ciudad del norte de España. Además, el estudio comparó los criterios diagnósticos para sarcopenia y evaluó las diferencias en el rendimiento funcional de acuerdo a ellos. Métodos: Se realizó un estudio transversal con 258 personas de ambos géneros, pertenecientes a centros comunitarios. La composición corporal se evaluó con absorciometría dual por rayos-X. El índice de masa magra apendicular (IMMA), la fuerza de prensión manual (FPM) y el 8 foot up­and­go test (8f­UG) fueron empleados para el diagnóstico de sarcopenia. Resultados: La frecuencia de sarcopenia fue de 2.4% (n=6). En las mujeres, el IMMA se correlacionó con el FPM (r= 0.164, p.

Factores asociados con la adherencia a la actividad física en el tiempo libre / Fatores associados com a aderência à atividade física no tempo libre / Associated factors with adherence to physical activity in leisure time

Introducci¢n: existe en Colombia poco conocimiento respecto a los facto- res asociados con la adherencia al ejercicio. Objetivo: evaluar los factores asociados con la adherencia a la actividad f¡sica en el tiempo libre (AFTL) de los adultos que participan en un programa de actividad f¡sica (AF). M‚- todos: se realiz¢ un estudio prospectivo de Casos y Controles. Se defini¢ como caso a quien realiz¢ durante un periodo de 5 meses un promedio 150 minutos o m s de AFTL por semana a una intensidad moderada ¢ 75 minutos a una intensidad vigorosa; como control se tom¢ a quien no cum- pli¢ con los anteriores requisitos. Se evaluaron variables independientes sociodemogr ficas, factores de riesgo cardiovascular y osteomuscular, y las motivacionales para la pr ctica del ejercicio. Los datos se analizaron por medio de un modelo de regresi¢n log¡stica multivariado. Resultados: la muestra la conformaron 176 personas usuarias de un programa de AF, en su mayor¡a mujeres (69,3%); el promedio de edad fue de 55,7 a¤os. Las variables asociadas con la adherencia a la AFTL fueron el antecedente personal de artrosis (OR 0,392; IC95% 0,184-0,837; p=0,016) y la edad (OR 1,027; IC95% 1,001-1,054; p=0,041), las cuales explicaron el 8,0% de la variabilidad. Conclusiones: las variables que se asociaron en forma independiente con la adherencia a la AFTL fueron la edad y el anteceden- te personal de artrosis. Se requiere realizar nuevos estudios que incluyan otras variables que puedan explicar en forma m s global este fen¢meno.

Introduction: In Colombia there is a low knowledge related to the associated factors with adherence to exercise. Objective: To evaluate the associated factors with adherence to the physical activity in leisure time in adults (PALT) who participate in a physical activity program. Methods: The study was a prospective case-control. A case was defined as who performed during five months an average of 150 minutes or more per week of PALT, with a moderate intensity or strong intensity of 75 minutes or more of PALT per week; as a control was had in consideration, people who did not meet the above criteria. The independent variables measured were: socio-demographic factors, cardiovascular, musculoskeletal risk factors, and the motivation to exercise. The data was analyzed through a varied regressive logistic model. Results: The sample involved 176 female users of a PA program (69.3%); with an average age of 55.7 years old. The associated variables with the PALT adherence were the personal osteoarthritis record (OR 0,392; IC95% 0,184 – 0,837; P=0,016) and the age (OR 1,027; IC95% 1,001-1,054; p=0,041), which explained 8, 0 % of the variability. Conclusions: The variables that were independently associated to the adherence to PALT were age, and the personal osteoarthritis record. There is a necessity of new studies that include new variables to allow a global analysis of the phenomena.

Ejercicio físico y depresión en adultos mayores: una revisión sistemática / Physical Exercise and Depression in the Elderly: A Systematic Review

Antecedentes: La literatura avala los beneficios del ejercicio para personas con trastornos depresivos; sin embargo, hay controversia sobre estos beneficios para personas adultas mayores deprimidas. Objetivo: Determinar el efecto de diferentes tipos de ejercicio en la depresión de adultos mayores mediante una revisión sistemática de ensayos clínicos. Fuentes de los datos: The Cochrane Library; PubMed-MEDLINE (1966-diciembre de 2010); EMBASE (1980-diciembre de 2010); LILACS (1986-diciembre de 2010); SCIELO (1998-diciembre de 2010), y Register of Controlled Trials; búsqueda manual en otros orígenes. Métodos: Se incluyeron ensayos clínicos con personas de edad > 60 años con diagnóstico de depresión, sin restricción por a ño de publicación, idioma y sexo, con intervenciones estructuradas de ejercicio y controlados con el cuidado usual (medicamentos, psicoterapia, terapia de electrochoque), placebo o sin intervención. Tres evaluadores realizaron la búsqueda, aplicaron los criterios de inclusión y exclusión, evaluaron la calidad metodológica y extrajeron los datos de manera independiente; las discrepancias se resolvieron por consenso. El desenlace primario fue la puntuación de los síntomas depresivos. Resultados: Se identificaron 11 estudios (n = 7.195). En general, el ejercicio produce mejoría de la depresión en adultos mayores, con mayor evidencia a corto plazo (3 meses) y con trabajos de fuerza a alta intensidad. Conclusiones: El ejercicio es benéfico para las personas adultas mayores con depresión; sin embargo, los estudios que lo respaldan son de baja calidad metodológica y heterogéneos, lo que hace necesario realizar ensayos clínicos que clarifiquen la magnitud del efecto y las dosis a las cuales es benéfico.

Background: The literature supports the benefits of exercise in people with depressive disorders, but there is controversy over these benefits in depressed elderly. Objective: To determine the effect of different types of exercise on depression in older adults using a systematic review of clinical trials. Data sources: The Cochrane Library; PubMed-MEDLINE (1966-dic 2010); EMBASE (1980-dic 2010); LILACS (1986-dic 2010); SCIELO (1998-dic 2010); Register of Controlled Trials; manual search in other sources. Methods: Clinical trials with people >60 years with diagnosis of depression were included, without restriction by year of publication, language and sex, with exercise intervention structures, controlled with usual care (medication, psychotherapy, electric shock therapy), placebo or non-intervention. Three independent reviewers conducted the search, applied inclusion and exclusion criteria, assessed methodological quality and extracted data; discrepancies were resolved by consensus. The primary outcome was the score for depressive symptoms. Results: A total of 11 studies (n =7195) were identified. In general, exercise produces an improvement in depression in older adults with more evidence in the short-term (3 months) and strength training at high intensity. Conclusions: Exercise is beneficial for older persons with depression, but studies that support this are of low methodological quality and heterogeneous, which makes it necessary to develop clinical trials to clarify the magnitude of the effect and the levels at which it is beneficial.

Efecto de una intervención con ejercicio físico y orientación nutricional sobre componentes del síndrome metabólico en jóvenes con exceso de peso / Effect of an intervention with physical exercise and nutritional guidance on the components of the metabolic syndrome among young people with overweight

Introducción: las intervenciones con ejercicio físico y orientación nutricional muestran cambios en el exceso de peso en jóvenes con el síndrome metabólico (SM); sin embargo, sus características y resultados son diversos.Objetivo: evaluar el efecto de una intervención con ejercicio físico y orientación nutricional sobre componentes del SM en jóvenes con exceso de peso.Materiales y métodos: estudio longitudinal con una evaluación antes y otra después, en nueve jóvenes entre 11 y 17 años. Se evaluaron aspectos antropométricos, frecuencia cardíaca en reposo (FCR), consumo pico de oxígeno (VO2pico), insulinemia, resistencia a la insulina (HOMA) y componentes de SM. La intervención consistió en 12 semanas de ejercicio supervisado, tres sesiones/semana de 90 minutos (aeróbico y de fuerza), más dos sesiones no supervisadas; el suministro semanal de frutas y verduras para cubrir las cinco porciones diarias recomendadas y educación nutricional individual y colectiva.Resultados: luego de la intervención disminuyeron la circunferencia de la cintura de 90,5 ± 11,0 a 88,1 ± 9,9 cm; el IMC de 30,2 ± 5,8 a 29,3 ± 5,6 kg/m2; la grasa corporal total de 39,8 ± 13,0 a 34,3 ± 9,0%; la glucemia de 86,0 ± 8,6 a 83,1 ± 5,0 mg/dL; la insulinemia de 23,2 ± 9,8 a 19,4 ± 7,6 µU/mL; el HOMA-IR de 2,89 ± 1,21 a 2,39 ± 0,93; la FCR de 87,9 ± 4,3 a 78,2 ± 5,5 bpm y aumentó el VO2pico de 36,3 ± 5,1 a 38,5 ± 4,1 mL/kg/min; de seis jóvenes con diagnóstico de SM al inicio, cuatro no lo presentaron al final.Conclusiones: participar en un programa de ejercicio y aumentar el consumo de frutas y verduras en los jóvenes con exceso de peso y componentes del SM generó modificaciones positivas en la composición corporal, el VO2pico, la FCR y la glucemia así como en los componentes y prevalencia del SM.

Introduction: Interventions with physical exercise and nutritional guidance show changes in overweight among young people suffering from the metabolic syndrome (MS); nevertheless, their characteristics and results vary.Objective: To assess the effect of an intervention with physical exercise and nutritional guidance on components of the MS among overweighted young people.Materials and methods: Longitudinal study with an assessment before and another after the intervention in nine young people aged 11 to 17 years. Anthropometric aspects, resting heart rate, peak oxygen consumption (VO2peak), insulinemia, HOMA, and components of the MS were assessed. Intervention consisted of 12 weeks of supervised exercise, three 90-minute sessions/week (aerobic and strength), plus two unsupervised sessions; the weekly supply of fruits and vegetables in order to cover the five recommended daily servings, and individual and group nutrition education.Results: With the intervention waist circumference decreased from 90.5 ± 11.0 to 88.1 ± 9.9 cm; BMI from 30.2 ± 5.8 to 29.3 ± 5.6 kg/m2; total body fat from 39.8 ± 13.0 to 34.3 ± 9.0%; glycemia from 86.0 ± 8.6 to 83.1 ± 5.0 mg/dL; insulinemia from 23.2 ± 9.8 to 19.4 ± 7.6 µU/mL; HOMA-IR from 2.89 ± 1.21 to 2.39 ± 0.93; resting heart rate from 87.9 ± 4.3 to 78.2 ± 5.5 rpm, and VO2peak increased from 36.3 ± 5.1 to 38.5 ± 4.1 mL/kg/min. Four out of six young people with the diagnosis of MS at the beginning of the study did not present it at the end.Conclusions: Participating in an exercise program and increase in the consumption of fruits and vegetables among overweighted young people with components of the MS produced positive modifications in body composition, VO2peak, resting heart rate, and glycemia, as well as in the components and prevalence of the MS.

Calidad de vida relacionada con la salud en usuarios de un programa de actividad física / Health-related quality of life in users of a physical activity program

Introducción: la calidad de vida relacionada con la salud (CVRS) permite evaluar el estado de salud de las personas y diseñar, implementar y evaluar programas de salud. Objetivo: determinar la percepción de la CVRS en usuarios de un programa de actividad física (AF). Metodología: estudio transversal en 177 sujetos pertenecientes a un programa de actividad física. Se aplicó el cuestionario SF-36v1.2 para evaluar la CVRS; se evaluó el consumo máximo de oxígeno (VO2máx) por medio la prueba de 2.000 metros y se determinó la prevalencia de algunos factores de riesgo cardiovascular a partir de las historias clínicas. Resultados: el puntaje promedio de CVRS más alto fue en el funcionamiento físico (FF) 90,5 (DE: 10,8) y más bajo en dolor corporal (DC) 78,1 (DE: 22,4) y vitalidad (VT) 78,1 (DE: 15,5). En las personas fumadoras, hipertensas, diabéticas, obesas y con niveles bajos de actividad fisica la mayoría de los puntajes de CVRS fueron más bajos (diferencias clínica y estadísticamente significativas). El VO2máx mostró correlación con los dominios funcionamiento físico (FF) (rho = 0,371; p = 0,0001), desempeño físico (DF) (rho = 0,177; p = 0,018) y dolor corporal (DC) (rho = 0,207; p = 0,006). Conclusión: las personas estudiadas tienen una percepción buena de la CVRS; sin embargo, en quienes reportaron tabaquismo, hipertensión arterial, diabetes mellitus, obesidad, dislipidemias y baja potencia aeróbica se presentó una menor percepción de la CVRS; las personas con obesidad mostraron mejores puntajes en los dominios del componente mental y aquellos con bajo nivel de AF mostraron puntajes bajos en dicho componente.

Introduction: Health related quality of life (HRQL) allows to assess people health status, and to design, implement and evaluate health programs. Objective: To determine the perception of HRQL in users of a physical activity (PA) program. Methodology: Cross-sectional study in 177 subjects belonging to a physical activity program. SF-36v1.2 questionnaire was used to assess HRQL; maximal oxygen consumption (VO2max) was evaluated by the 2.000 meters test and prevalence of some cardiovascular risk factors was determined from medical records. Results: The higher average score for HRQL was in physical function (PF) 90,5 (SD: 10.8), compared with the lowest scores of body pain (BP) 78,1 (SD: 22,4) and vitality (VT) 78,1 (SD: 15,5). In smokers, hypertensive, diabetics, obese and people with low levels of physical activity most HRQL scores were lower (clinically and statistically significant differences). VO2max correlated with PF subscales (rho = 0.371; p = 0.0001), physical performance (rho = 0.177; p = 0.018) and BP (rho = 0.207; p = 0.006). Conclusion: The studied individuals have a good perception of HRQL; nevertheless, those who reported smoking, hypertension, diabetes, obesity, dyslipidemia and low aerobic power, had a reduced perception of HRQL; obese people showed improved scores in mental component domains and those with low levels of PA showed low scores in that component.
