Análise da aptidão aeróbia de acadêmicos de educação física por meio de teste indireto submáximo

Abstract

Higher education is a moment of transition in the lives of students, generating changes in lifestyle that, together with the advancement of technology, hectic working hours, health can be compromised, resulting in physical inactivity. With less frequent body practices and without adequate aerobic fitness, there is a greater risk of cardiovascular risk factors and metabolic syndrome. The study aimed to estimate the aerobic fitness of students entering and graduating from the physical education course. A cross-sectional descriptive study was carried out with 56 students enrolled in the 1st and 8th periods of the Physical Education course (semesters of 2018-2 and 2019-1). To estimate the maximum VO2 of the volunteers, a submaximal treadmill test proposed by Machado (2012) was used, which consists of the volunteer running for 6 minutes at a speed of 8 km/h, with their heart rate measured through a frequency meter and recorded at every 30 seconds. For the analysis of the distribution of data, the Shapiro-Wilk normality test was used, and the comparison of variables between groups was performed using the Mann-Whitney test, considering the significance level of 5% (p<0,05). The results showed that most students in the physical education course had aerobic fitness classified as "excellent". VO2 maximum of the beginners, both male and female, did not differ from the graduates. On the other hand, when comparing the maximum relative VO2 between sexes, a significant difference was found, with higher values for female academics, a result that may be related to the specific protocol used in the study.
