Influência do período do dia no desempenho em uma bateria de testes de aptidão física em jovens universitários

Abstract

This work aims to investigate whether the time of day influences the performance of individuals in a TAF battery. The sample consisted of ten individuals of both genders (24.10±0.96 years), who performed the FAT in three periods of the day: morning, afternoon and night, on three non-consecutive days over the course of a week. The FAT consisted of five tests (handgrip test, fixed bar test, abdominal flexion test, horizontal impulsion test and Shuttle-run) for men and four tests for women, who did not perform the strength test on the bar. fixed. On the first day of the battery of tests, they underwent an anthropometric and body composition assessment with bioimpedance. On each evaluation day, the participants had their body temperature measured before starting the tests and answered the subjective perception of exertion (RPE) after each test. For the statistical analysis, one-way anova with Bonferroni post-hoc was used to compare performance differences over the three periods of the day. No significant differences (P>0.05) were found in the performance between the tests performed, nor in the PSE in the comparisons between the three periods of the day. Body temperature was significantly (P<0.01) lower in the morning (36.28±0.08 ºC) when compared to the afternoon (36.54±0.69 ºC) and night (36.70 ±0.10 ºC). Thus, it is possible to conclude that the time of day does not influence the performance of young adults in a TAF battery.
