RESUMO

The aim of this study was to investigate the association between physical activity (PA), both occupational (OPA) and during leisure time (LTPA), with obesity and cardiovascular risk factors in Chilean adults. 5,157 participants from the Chilean National Health Survey 2009-2010 were included in this study. OPA and LTPA levels were assessed using the Global Physical Activity Questionnaire. The association between both PA with obesity and cardiovascular risk factors was determined using logistic regression. Our findings showed a significant trend between higher LTPA and lower odds for obesity (OR 0.64 [95% CI: 0.53; 0.76], central obesity 0.52 [0.44; 0.61]) and other cardiovascular risk factors including diabetes (OR: 0.72 [0.55; 0.94]), hypertension (OR: 0.59 [0.50; 0.71]) and metabolic syndrome (OR: 0.62 [0.50; 0.78]). In contrast, OPA was only associated with lower odds of diabetes (OR: 0.79 [0.65; 0.98]) and hypertension (0.85 [0.74; 0.98]). In conclusion, LTPA was associated with a lower risk of all major cardiovascular risk factors, whereas OPA was only associated with a lower risk of diabetes and hypertension.

RESUMO

Resumen La prueba de caminata de seis minutos (PC6M) consiste en recorrer la mayor distancia posible y se caracteriza por ser una prueba de fácil realización. El objetivo de esta revisión fue examinar la relación entre las variables de distancia recorrida, patologías cardíacas, pulmonares y el consumo de oxígeno de una prueba de criterio en cinta rodante y/o cicloergómetro, y las ecuaciones de predicción del VO2 en la PC6M de Maldonado e Ingle (2006), Vanhelst (2013) y Costa (2017) para personas con patologías. El manuscrito es una revisión bibliográfica que utilizó las bases de datos Scopus y WOS, con artículos en inglés, español y portugués entre 2000 y 2017. La distancia es la variable que más se midió y que más se asoció con el VO2, encontrándose correlaciones significativas con valores de 0.01 hasta 0.8, las patologías más relacionadas con el VO2 máx. fueron la hipertensión pulmonar, enfermedad pulmonar obstructiva, insuficiencia cardíaca, disfunción sistólica ventricular y accidente cerebro-vascular y el cicloergómetro fue el más utilizado en las pruebas de criterio de VO2 máx. Solo una ecuación fue elaborada para niños que eran obesos la que incluyó distancia e IMC (Vanhelst), otra ecuación fue para adultos con enfermedad cardíaca que además incluía el sexo (Costa), una en pacientes con disfunción sistólica ventricular que aparte incorporó la edad, volumen espiratorio y hemoglobina (Ingle) y otra fórmula fue para adultos con insuficiencia cardíaca que consideró la distancia (Maldonado). Se sugiere utilizar la ecuación más apropiada y elaborar modelos predictivos para personas con diversas características.


Abstract The six-minute walk test (SMWT) consists of walking as far as possible and is characterized by being an easy test to perform. This paper examines the relationship between the variables of distance traveled, cardiac and pulmonary pathologies, and the oxygen consumption of a criterion test on treadmill and/or cycle ergometer, and the prediction equations of VO2 in the SMWT of Maldonado and Ingle (2006), Vanhelst (2013) and Costa (2017) for people with pathologies. The paper is a bibliographic review that used the Scopus and WOS databases containing articles in English, Spanish and Portuguese, published between 2000 and 2017. Distance is the variable that was most measured, and it was most associated with VO2; correlations with values from 0.01 to 0.8 were found. The pathologies most related to VO2 max were pulmonary hypertension, obstructive pulmonary disease, and ventricular heart failure and stroke; and the cycle ergometer was the most commonly used in the VO2 max criterion tests. Only one equation was created for children who were obese; it included distance and BMI (Vanhelst). Another equation was generated for adults with heart disease that also included sex (Costa). Besides, one equation was for patients with ventricular systolic dysfunction that also incorporated age, volume expiratory and hemoglobin (Ingle); another one was created for adults with heart failure, and this formula considered the distance (Maldonado). It is suggested to use the most appropriate equation and create predictive models for people with different characteristics.


Resumo O teste de caminhada de seis minutos (TC6M) consiste em andar o mais longe possível e é caracterizado como um teste fácil. O objetivo desta revisão foi examinar a relação entre as variáveis distância percorrida, patologias cardíacas, pulmonares e o consumo de oxigênio de um teste de critério em esteira e/ou ciclo ergômetro, e as equações de predição do VO 2 no TC6M de Maldonado e Ingle (2006), Vanhelst (2013) e Costa (2017) para pessoas com patologias. O manuscrito é uma revisão bibliográfica que utilizou as bases de dados Scopus e WOS, com artigos em inglês, espanhol e português entre 2000 e 2017. A distância é a variável mais medida e mais associada ao VO 2, encontrando correlações significativas com valores de 0,01 a 0,8, as patologias mais relacionadas ao VO 2 max. foram a hipertensão pulmonar, doença pulmonar obstrutiva, insuficiência cardíaca, disfunção sistólica ventricular e acidente vascular encefálico e o ciclo ergômetro foi o mais utilizado nos testes do critério VO 2 max. Apenas uma equação foi desenvolvida para crianças obesas, que incluíram distância e IMC (Vanhelst), outra equação foi para adultos com doença cardíaca que também incluiu sexo (Coast), uma em pacientes com disfunção sistólica ventricular que incorporaram a idade, volume expiratório e hemoglobina (Ingle) e outra fórmula foi para adultos com insuficiência cardíaca que considerou a distância (Maldonado). Sugere-se utilizar a equação mais adequada e desenvolver modelos preditivos para pessoas com características diversas.

RESUMO

Introduction: Background: international physical activity (PA) guidelines recommend 150 minutes of moderate to vigorous PA or 75 minutes of vigorous PA weekly; however, the proportion of the Chilean population who meet this recommendation across the lifespan remains unknown. Objective: to characterize PA patterns by age categories and sex in the Chilean population. Methods: participants from the Chilean Health Survey 2009-2010 (5,293 individuals) were included in this study. PA types (transport, moderate and vigorous) and sedentary behavior were measured using the global physical activity questionnaire (GPAQ). Time spent on different intensities of physical activity by age and sex was investigated using regression analyses. Results: compared to participants aged < 20 years (reference group), commuting-related PA decreased for both men and women from the age of 60 years onwards. Moderate intensity PA increases for both sexes reaching the highest level between the ages of 40-49 years, and then it shows a decline with increasing age. Vigorous PA reaches the highest levels between ages 30-39 and 40-49 years for women and men, respectively. Time spent sitting increased markedly on participants aged 60 years and above, reaching the highest levels at the age of 80 years. Conclusion: in the Chilean population, there are clear patterns of change in PA levels and sitting time across age groups. These findings may help informing stakeholders on tailoring interventions to increase PA levels, especially at ages when the population is more likely to reach their lowest levels of activity.

RESUMO

Antecedentes: las recomendaciones internacionales fomentan la realización de al menos 150 minutos de actividad física (AF) moderada/vigorosa o 75 minutos de AF vigorosa semanalmente; sin embargo, se desconoce cuál es el porcentaje de cumplimiento de estas recomendaciones en los distintos grupos etarios chilenos. Objetivo: caracterizar los patrones de AF según grupos etarios y sexo en población chilena. Métodos: fueron incluidos 5.293 participantes de la Encuesta Nacional de Salud (ENS) 2009-2010. Se determinaron los niveles de AF (de transporte, moderada y vigorosa) y el tiempo sedentario a través del cuestionario GPAQ V2. El tiempo total destinado a los diferentes tipos de AF y el tiempo sedentario entre las diferentes categorías de edad fueron analizados según sexo mediante regresión lineal. Resultados: en comparación con el grupo < 20 años, la AF de transporte muestra una disminución a partir de los 60 años en ambos sexos. En ambos sexos, la AF de intensidad moderada alcanzó su nivel más alto entre los 40-49 años, pero posterior a esta edad se observó una pronunciada disminución. La AF vigorosa alcanzó su nivel más alto entre los 30-39 años para mujeres y 40-49 años para hombres. Finalmente, el tiempo sedente se incrementó a partir de los 60 años, alcanzando su nivel más alto en ≥ 80 años en ambos sexos. Conclusión: los patrones de AF en población chilena se modifi can con la edad y su intensidad varía por sexo. Estos resultados podrían orientar el desarrollo de políticas y programas que promuevan la realización de AF, especialmente en edades donde se observan los niveles más bajos

RESUMO

Introducción: En Chile existe alto porcentaje de sedentarismo que trae como consecuencia factores de riesgo de obesidad y enfermedades crónicas no transmisibles. Un medio no farmacológico para tratarlas es el ejercicio físico, que practicado de manera regular reduce factores de riesgo. Objetivo: determinar los efectos del entrenamiento interválico aeróbico de alta intensidad y fuerza muscular en funcionarios obesos con ECNT en una universidad chilena. Método: Se aplicó un programa de 16 semanas en el que participaron 18 funcionarios universitarios voluntarios, quienes fueron asignados a un grupo de entrenamiento o a un grupo control. Este programa consistió en ejercicios interválicos en bicicleta y de fuerza muscular localizada, ambos de media-alta intensidad con duración de 30 minutos por sesión, tres veces por semana. Se comparó pre y postest intragrupo (GE y GC) con la prueba T-Student de muestras relacionadas y cada pre test y cada postest intergrupo con T-Student para muestras independientes, (p<0,05) entre ambos grupos. Resultados: En el grupo control se mantuvieron y no modificaron las diversas variables evaluadas, aunque se encontraron aumentos en los triglicéridos, presión arterial sistólica y diastólica, en contraste con el grupo de entrenamiento, quienes reportaron una disminución significativa en el perímetro de cintura (Pre test:101,33; Postest: 97,22) y el ICE (Pre test:0,65; Postest: 0,62) (p=0,017), en la presión arterial sistólica, la presión arterial diastólica, triglicéridos y la frecuencia cardiaca de reposo, aunque no significativos. En el colesterol total hubo aumentos, aunque no significativos. Por otra parte, el doble producto (frecuencia cardiaca x presión arterial sistólica) solo se redujo en el grupo de entrenamiento. Conclusiones: Los datos sugieren que el entrenamiento interválico aeróbico de media-alta intensidad mejora la respuesta hemodinámica en ejercicio submáximo en pacientes con obesidad y ECNT. La disminución del perímetro abdominal y el ICE es un buen indicador de la mejora de adiposidad corporal


Introduction: In Chile there is a high percentage of sedentary lifestyle behaviors that results in risk factors of obesity and chronic non communicable diseases. A non-pharmacological means to treat them is physical exercise, which practiced on a regular basis reduces risk factors. Objective: to determine the effects of high intensity aerobic training and muscle strength in obese staff with CNCD in a Chilean university.Method: A 16-week program was applied in 18 volunteer university staff, who was assigned to a training group (TG) or a control group (CG). This program consisted of interval medium-high intensity exercises in bicycle and localized muscular strength, with duration of 30 minutes per session, three times a week. Pre and post-intragroup (TG and CG) were compared with the T-Student test of related samples and each pre-test and each post-test intergroup with student's Ttest for independent samples (p <0.05) between both groups. Results: In the control group the variables evaluated were maintained and not modified, although increases in triglycerides, systolic and diastolic blood pressure were found, in contrast to the training group, who reported a significant decrease in waist circumference (Pre test: 101.33; Posttest: 97.22) and ICE (Pre test: 0.65; Posttest: 0.62) (p = 0.017), systolic blood pressure, diastolic blood pressure, triglycerides and frequency cardiac arrest, although not significant. In total cholesterol, there were increases, although not significant. On the other hand, the double product (heart rate x systolic blood pressure) was only reduced in the training group. Conclusions: The data suggest that medium-high intensity aerobic interval training improves the hemodynamic response in submaximal exercise in patients with obesity and CNCD. The decrease in abdominal perimeter and ICE is a good indicator of the improvement of body fat

RESUMO

BACKGROUND: The six-minute walk test (SMWT) is an easy-to-use test that measures walking distance. AIM: To elaborate an equation to estimate the maximum oxygen consumption (VO2 max) using the results of the SMWT. MATERIAL AND METHODS: Forty men and 40 women aged 22.5 ± 2 years, underwent a SMWT to measure the total walked distance and the recovery heart rate (RhR) Also, VO2 max was estimated from the maximal workload achieved in a cyclo-ergometer using the Storer test. A multivariate regression analysis resulted in a prediction equation that was validated with distributional assumptions of normality, independence and homoscedasticity. The limits of concordance of the predictive model were checked with the Bland-Altman diagram. RESULTS: Body mass index (BMI), sex, RhR and total walked distance explained VO2 max variance by 3.4, 73.1, 17.9 and 32.8%, respectively. The prediction equation achieved was VO2 max (ml.min-1) = -3672.585 + (966.472 × Sex [1: female, 2: male]) + (-18.492 X RhR [beats.minute-1]) + (9.191 X Distance [m]) + (87.707 × BMI). The R2 of the equation was 0.91 (p < 0.01). CONCLUSIONS: This equation predicts VO2 max in Chilean university students according to sex, BMI, cardiovascular response and performance in the SMWT.

RESUMO

Fundamentos: En Chile el 40% de la población entre 15 y 19 años tiene malnutrición por exceso. La evaluación a través de la antropometría y la actividad física (AF) funcional brindan un diagnóstico más completo. El objetivo fue elaborar una ecuación para predecir el desempeño aeróbico en la Prueba de caminata de seis minutos (PC6M) desde el estado nutricional, antropometría y AF en adolecentes chilenos de ambos sexos. Métodos: Participaron 180 adolescentes con edad promedio de 16 años, se les determinó el peso corporal y la estatura, respondieron un cuestionario de hábitos de vida sobre AF y consumo de drogas, entre otros, y realizaron la PC6M. Se comparó las variables por sexo y las que se relacionaron significativamente con la distancia en la PC6M se incluyeron en una ecuación multivariada. Finalmente se verificó la concordancia entre la ecuación y la PC6M con el diagrama de Bland-Almant. Se utilizó el programa SPSS v20 (p<0,05). Resultados: Existió diferencias significativas en las características corporales, la AFy la PC6M, siendo mayores en hombres, la mayoría de los adolescentes no consumen drogas lo que es similar en ambos sexos. La ecuación que predice la distancia en la PC6M es 479,477 + (46,581 ˣ Sexo) + (74,441 ˣ Estatura) + (-0,865 ˣ IMC) + (10,784 ˣ AF) con valor p<0,001, y según Bland-Altman no hubo diferencias entre la ecuación y la PC6M (p=0,845). Conclusiones: Las características corporales de estatura e IMC, la AF y ser hombre o mujer predicen la distancia en la PC6M, pero la explican en un bajo porcentaje


Background: In Chile, 40% of the population between 15 and 19 years old has malnutrition by excess. The evaluation through anthropometry and functional physical activity (PA) provide a comprehensive diagnosis. The aim was to develop an equation to predict the aerobic performance in the Six-minute walk test (SMWT) from the nutritional status, anthropometry and PA in Chilean adolescents of both sexes. Methods: A total of 180 adolescents with an average age of 16 years participated, their body weight and height were determined; they answered a questionnaire related to life habits, PA and drug consumption, among others, and performed the SMWT. The variables compared by sex and those that are significantly related to distance in the SMWT, were included in a multivariate equation. Finally, the concordance between the equation and the SMWT was verified with the Bland-Almant diagram. The SPSS program, v20, was used (p<0.05). Results: There were significant differences in body characteristics, PA and SMWT, being higher in men; the majority of adolescents do not consume drugs, which is similar in both genders. The equation that predicts the distance in the SMWT is 479.477 + (46.581 ˣ Gender) + (74.441 ˣ Height) + (-0.865 ˣ BMI) + (10.784 ˣ PA) with value p<0.001, and according to Bland-Altman there were no differences between the equation and the SMWT (p=0.845). Conclusions: The corporal characteristics of height and BMI, the PA and being male or female predict the distance in the SMWT, but they explain it in a low percentage

RESUMO

ABSTRACT The Six-Minute Walking Test (SMWT) was completed just in few times in apparently healthy young individuals and university students, while the maximal volume of oxygen consumption (VO2max) prediction has not been taken into consideration. The aim of this study was to elaborate a prediction equation for VO2max from the heart rate recovery (HRR) after completion the SMWT. 127 young in the first stage completed the SMWT and Course Navette Test (CNT), 17 in the second stage (test-retest) completed the SMWT and CNT, and 20 subjects in the third stage completed the SMWT and Bruce test. All physical education students (PES) completions an informed consent. A significant correlation was observed between VO2max estimated trough the CNT and HRR after the SMWT (rho= -0.3; p= 0.001). The correlation between the same variables was r= -0.72 (p= 0.001) in the second stage, and a significant correlation (r= -0.65; p= 0.002) was observed between VO2max directly measured in Bruce test and HRR after the SMWT. From the correlation a prediction equation was elaborated is y= 92.468-(0.278*20-second-HRR) and the standard error of estimation (SEE) was 7.17 ml·kg-1·min-1. The HRR achieved after the SMWT may predict VO2max in PES.


RESUMO O teste de caminhada de seis minutos (SMWT) foi concluído em poucas ocasiões em indivíduos jovens aparentemente saudáveis e estudantes universitarios, enquanto que a predição máxima do consumo de oxigênio (VO2max) não foi tomada em consideração. O objetivo deste estudo foi elaborar uma equação de predição para VO2max a partir da recuperação da freqüência cardíaca (HRR) após a realização do SMWT. 127 jovens na primeira etapa completaram o SMWT eo Course Navette Test (CNT), 17 na segunda etapa (teste-reteste) completaram o SMWT e CNT, e 20 sujeitos na terceira etapa completaram o teste SMWT e Bruce test. Todos os estudantes de educação física (PES) completam o consentimento informado. Observou-se uma correlação significativa entre o VO2máx estimado pela CNT e a HRR após o SMWT (rho= -0,3; p= 0,001). A correlação entre as mesmas variáveis foi r= -0,72 (p= 0,001) na segunda etapa e observou-se uma correlação significativa (r= -0,65; p= 0,002) entre VO2max medido diretamente no teste de Bruce e HRR após o SMWT. A partir da correlação foi elaborada uma equação de predição de y= 92,468-0,278*20-segundo-HRR) eo erro padrão de estimação (SEE) foi de 7,17 ml·kg-1·min-1. O HRR conseguido após o SMWT pode predizer VO2max no PES.

RESUMO

Introducción: los universitarios están sujetos a cambios en estilos de vida a nivel social, psicológico y biológico. Objetivos: determinar diferencias en la antropometría, niveles de actividad física y condición física en estudiantes de educación física de ambos sexos entre el primer y cuarto año de universidad. Métodos: estudio de evolución de grupo donde se midió a 28 estudiantes al primer y cuarto año en antropometría con el protocolo ISAK, niveles de actividad física con el cuestionario IPAQ corto y condición física. Se utilizó la prueba t de Student para muestras relacionadas (p<0,05) con el programa SPSS v24. Resultados: el peso corporal, índice cintura cadera, perímetro de cintura y abdominal aumentaron (p<0,01) y el IMC (p=0,116). La mayoría de los pliegues de miembro superior y tronco disminuyeron, aunque el de la cresta ilíaca (p<0,0001) y abdominal (p=0,031) de forma significativa. El coste energético de la actividad física moderada, caminata y actividad física semanal disminuyeron, pero solo este estadísticamente (p=0,048). Las flexo-extensiones de codo, resistencia cardiorrespiratoria y salto horizontal aumentaron, este último de manera significativa (p=0,004), pero la prueba de abdominales y la flexibilidad disminuyeron. Discusión: disminuyó el peso, perímetro de cintura e IMC en estudiantes de educación física chilenos, en nuestra investigación el índice cintura cadera y el peso aumentaron. El gasto energético disminuyó y concuerda con el de personas con estudios universitarios tras 13 años. En la condición física no es claro, el rendimiento aumenta o disminuye comparado con otros estudiantes de educación física. Conclusiones: la adiposidad corporal aumentó al paso de los años, niveles de actividad física y condición física disminuyeron


Introduction: university students are subject to changes in their lifestyles at a social, psychological and biological level. Objectives: was to determine differences in anthropometry, physical activity levels and physical condition in physical education students of both genders between the first and fourth year of career. Methods: study with group evolution (cohort) with 28 students. The anthropometry with the ISAK protocol were measured at the first and fourth year, physical activity levels with the short version IPAQ questionnaire and physical condition with indirect tests. The Student's t-test for related samples (p<0.05) was used with the SPSS program v24. Results: body weight, waist-hip index, waist and abdominal circumference increased (p<0.01) and BMI (p=0.116). Most of the upper limb and trunk folds decreased, although that of the iliac (p<0.0001) and abdominal (p=0.031) crest significantly. The energy cost of moderate, walking and weekly physical activity decreased, but only statistically (p=0.048). Flexo-extensions of the elbow, cardiorespiratory resistance and horizontal jump increased, the latter significantly (p=0.004), but the abdominal test and flexibility decreased. Discussion: the weight, waist circumference and BMI of Chilean physical education students decreased, in our research the hip waist index and weight increased. The energy expenditure decreased and agrees with people who have college studies after 13 years. In physical condition it is not clear if the performance increases or decreases compared with other physical education students. Conclusions: body adiposity increased over the years, physical activity levels and physical condition decreased

RESUMO

Introducción: El incremento de la población de adultos mayores (AM) es una realidad global que plantea a las sociedades grandes retos y oportunidades. Objetivo: Relacionar la calidad de sueño y percepción de la calidad de vida con el estado nutricional y riesgo cardiometabólico en AM chilenos físicamente activos. Material y método: Estudio transversal que evaluó 212 AM. Se estudió el índice de calidad del sueño de Pittsburgh, la escala de somnolencia de Epworth, la calidad de vida relacionada con la salud SF-36, el estado nutricional según el índice de masa corporal y el riesgo cardiometabólico según perímetro de cintura e índice cintura estatura. Se realizaron comparaciones a través de la prueba t de Student y asociaciones por medio de regresión logística, considerando un p<0,05. Resultados: Los AM evaluados presentaron diferencias significativas sólo entre las mujeres para latencia al sueño (p=0,022). Además, la regresión logística manifestó relación entre menor latencia al sueño con baja probabilidad de presentar sobrepeso/obesidad (OR=0,276; IC95%=0,086-0,887; p=0,031). Por su parte, menor cantidad de sueño aumenta la probabilidad de presentar sobrepeso/obesidad (OR=3,921; IC95%=1,061-14,490; p=0,031). La calidad de vida no reportó relaciones significativas con el estado nutricional ni con el riesgo cardiometabólico. Conclusiones: Los AM chilenos que participan en talleres gubernamentales de actividad física que presentan mayor latencia al sueño y menor cantidad de sueño exhiben más riesgo de poseer sobrepeso/obesidad. Además, la percepción de la calidad de vida es positiva independiente de su estado nutricional o riesgo cardiometabólico


Introduction: The increase in the population of older adults is a global reality that poses great challenges and opportunities to societies. Objective: To relate sleep quality and the perception of quality of life with the nutritional status and cardiometabolic risk in Chilean physically active older adults. Material and method: Cross-sectional study that evaluated 212 older adults. We studied the Pittsburgh Sleep Quality Index, the Epworth Sleepiness Scale, the health-related quality of life SF-36, the nutritional status according to body mass index and the cardiometabolic risk according to waist circumference and waist-to-height ratio. Comparisons were made through the Student's t-test and associations through logistic regression, considering p<0.05. Results: Older adults evaluated showed significant differences only among women for sleep latency (p=0.022). In addition, the logistic regression showed a relationships between lower sleep latency with a low probability of being overweight/ obesity (OR=0.276, 95% CI=0.086-0.887, p=0.031). On the other hand, less sleep increases the probability of being overweight/obesity (OR=3.921, 95% CI=1.061-14.490, p=0,031). The dimensions of quality of life did not report significant relationships with nutritional status or cardiometabolic risk. Conclusions: Chilean older adults participating in physical activity governmental workshops that present greater sleep latency and less sleep exhibit a higher risk of being overweight/ obesity. In addition, the perception of quality of life is positive regardless of their nutritional status or cardiometabolic risk

RESUMO

Introducción: se puede utilizar medios simples para predecir el VO2 máx., como a través de las características corporales y el estilo de vida. Objetivos: elaborar una ecuación para estimar el VO2 máx. en base al peso, estatura, variables del estilo de vida y cardiovasculares en estudiantes universitarios. Métodos: participaron 35 hombres y 35 mujeres de 22,5±1,9 años a quienes se les midió el peso corporal, estatura, se registró el consumo de alcohol, tabaco y medicamentos, variables cardiorrespiratorias en reposo y el VO2 máx. en una prueba en cicloergómetro hasta el agotamiento. Se determinó la correlación entre variables, se incluyeron en una ecuación multivariada y se verificó la concordancia del modelo con el diagrama de Bland-Altman. Se asignó una significancia de p<0,05 con el programa SPSS v.20. Resultados: la ecuación de predicción es VO2 máx. (ml.min-1) = -1268,945 + (1305,94 × Sexo [Mujer= 2; Hombre= 1]) + (17,868 × Peso) + (1034,204 × Estatura) + (-97,223 × Medicamentos [SI= 1; NO= 2]) + (3,867 × Presión arterial sistólica [PAS]) + (-5,574 × frecuencia cardíaca reposo [FCr]) (r= 0,892; r2= 0,795; p<0,001). Según Bland-Altman no hay diferencias entre la ecuación y el test en cicloergómetro (p= 0,644) y ningún valor del VO2 máx. estuvo fuera de los límites de concordancia. Discusión: el principal hallazgo es que el peso y la estatura tienen el mayor poder predictivo, junto al sexo, y las demás variables lo aumenta, además, es un estudio pionero en Chile. Algunas investigaciones utilizan características corporales y estilos de vida para predecir el VO2 máx., pero solo dos incluyen el tabaquismo, una la FC y ninguna la presión arterial. Conclusiones: variables antropométricas, del estilo de vida y cardiovasculares predicen el VO2 máx. Se puede utilizar el modelo predictivo considerando las diferencias entre las características de las personas y entre países


Introduction: To predict VO2 max it can be used simple means such as body characteristics and lifestyle. Aim: To elaborate an equation to estimate the VO2 max based on body weight, height, lifestyle and cardiovascular variables in college students. Methods: In a sample of 35 men and 35 women of 22.5±1.9 years body weight, height, consumption of alcohol, tobacco and medications, cardiorespiratory variables at rest and VO2 max in a cycle ergometer test until exhaustion were measured. A correlation between variables was determined, which were included in a multivariate equation and the agreement of the model with the Bland-Altman diagram was verified. A significance of p<0.05 was assigned with the SPSS v.20 program. Results: the prediction equation is VO2 max (ml.min-1) = -1268.945 + (1305.94 × Sex [Female = 2, Male = 1]) + (17.868 × Weight) + (1034.204 × Height) + (-97.223 × Medications [YES = 1, NO = 2]) + (3.867 × Systolic blood pressure) + (-5.574 × Resting heart rate [HRr]) (r = 0.892, r2 = 0.795, p<0.001). According to Bland-Altman there are no differences between the equation and the cycle ergometer test (p = 0.644) and no values of VO2 max were outside the limits of agreement. Discussions: the main finding is that weight and stature have the greatest predictive power, along with sex, and the other variables increase it, in addition, it is a pioneering study in Chile. Some research uses body characteristics and lifestyles to predict VO2 max, but only two include smoking, one HR and none blood pressure. Conclusions: Anthropometric, lifestyle and cardiovascular variables predict VO2 max. The predictive model can be used considering the differences between the characteristics of people and between countries

RESUMO

El objetivo de esta investigación es obtener una ecuación para determinar VO2 máx. a través de una prueba submáxima utilizando la frecuencia cardíaca de recuperación (FCr). Se diseñó en un estudio descriptivo correlacional dentro de un marco cuantitativo y se evaluó a 18 sujetos, 9 damas y 9 varones, de primero a cuarto año estudiantes de educación física con un muestreo de tipo intencional. Se midió la FCr en la prueba submáxima en escalón de McArdle, utilizando el monitor de FC marca Polar mo-delo V800 (Finlandia), y el consumo máximo de oxígeno (VO2 máx.) en el test de esfuerzo máximo de Bruce con el analizador de gases marca COSMED, modelo Fitmate PRO (Italia). En los resultados, la correlación (coeficiente de Pearson) que se obtuvo fue de r = ­0.84 (p<0.001) la cual se encuentra en una categoría considerable, obteniendo la ecuación y = ­0.4132 x + 110.68 con un error de estimación estándar (EEE) de 5.8 ml.kg.min­1.


The main aim of this research is to obtain an equation to determine the VO2 max through a submaximal test using heart rate recovery (HRr). A correlational descriptive study was designed within a quantitati-ve framework, where 18 subjects, all physical education college students, from freshman to senior year, were evaluated (9 females and 9 males), using diversity sampling (intentional). The HRr was measured in the McArdle submaximal step using the HR monitor, Polar V800 model (Finland), and the VO2 max. in the Bruce maximum effort test was measured with the gas analyzer COSMED model Fitmate PRO (Italy). In the results, the correlation (Pearson coefficient) obtained was r = −0.84 (p<0.001) which is within the considerable category, obtaining the equation y = 0.4132 x + 110.68 with a standard error of estimation (SEE) of 5.8 ml.kg.min−1.
