Dispêndio energético de estudantes de educação física em diferentes níveis de intensidades de atividade física

Abstract

Objective: To estimate the weekly energy expenditure of physical education students at different intensities of physical activity and verify whether there is a difference between beginners and seniors and females and males. Method: Cross-sectional descriptive study conducted with 242 students enrolled in the 1st and 8th period of the Physical Education course (2016 to 2020), with 95 beginners and 147 seniors, 154 males and 88 females. The level of physical activity and energy expenditure were estimated based on the International Physical Activity Questionnaire - IPAQ, short version. Results: Significant differences were observed for the duration of moderate activity (p=0.0378), general sum of frequencies (p=0.0324) and general sum of durations (p=0.0098), with higher values for the 1st period. When comparing the sexes, a significant difference was found for the duration of walking, frequency of moderate and vigorous activity, for the overall sum of frequencies and durations of physical activities. There was a significant difference in energy expenditure for all categories, with higher medians for the male group. Conclusions: There was a difference in the overall sum of frequencies, durations and duration of moderate intensity activities for the 1st period. Higher values for walking duration, frequency of moderate and vigorous activity, general sum of frequencies and durations of physical activities, for males. Higher values of energy expenditure in different physical activity intensities in all categories for the male group.
