Physical activity related to forced vital capacity and strength performance in a sample of young males and females

Abstract

ABSTRACT: To identify the extent of physical performance differences between active and sedentary subjects taking into account sexual dimorphism physical activity level was recorded by interview from a sample of 319 young university students of both sexes. Anthropometric variables and physical performance values were obtained. The sex factor was the main variable explaining the differences in physical performance between active and sedentary young. Also contributors to those differences were forced vital capacity (FVC), heart rate after exercise and rest heart rate, together with the explosive component of strength (vertical jump). The effect of physical activity was shown in the increment of FVC and the decrease of resting heart rate. In the overall sample, heart rate after exercise, either in active males or active females, was lowered with respect to the sedentary subjects, showing that active females experienced a greater cardiovascular benefit following adaptation to training than sedentary.
