Efeito do treinamento resistido na qualidade dos acadêmicos de educação física na Universidade Pública do Norte do Tocantins no contexto da pandemia de COVID-19

Abstract

The general objective of the study was to verify the effect of resistance training on improving sleep quality in Physical Education students in the context of the COVID-19 pandemic. Case-control study with a sample of 50 participants divided into two groups: case group (intervention), students practicing resistance training; and control group, students who did not practice resistance training. The students responded to sociodemographic questionnaires and the variables assessed by the International Physical Activity Questionnaire (IPAQ), short version, and the Pittsburgh Sleep Quality Index (PSQI). For the second stage, students who agreed to participate in the physical activity program through bodybuilding-type resistance training were included, for one month, five times a week, for 60 minutes, totaling 22 sessions. At the end of the intervention, both groups were reassessed. Data analysis was performed using descriptive and inferential statistics, in addition to multivariate analysis of variance for repeated measures and Wilk's Lambda test. The results of the effect of the intervention with resistance training on sleep quality showed a decrease in the post-test value, indicating an improvement in sleep quality. In the control group, the values increased, indicating a worsening in the quality of sleep of those who did not practice resistance training. There was a statistically significant difference between the groups (p<0.001). Therefore, resistance training appears to be efficient as a physical exercise in improving the quality of sleep of Physical Education Course students.
