Proposta de prescrição de exercício aeróbio baseada na valência afetiva: uma revisão sistemática

Abstract

The regular practice of aerobic physical exercises contributes to the reduction of sedentary rates. However, a large part of the population is not active enough. Studies about the affective responses during aerobic exercise point to an inverse and consistent relationship between the level of affect and the intensity of the effort. Thus, the possibility of prescribing exercise based on affective valences opens up. This dissertation sought, through a systematic review of the literature, to propose a strategy for prescribing the intensity and duration of aerobic exercise based on affective responses. The review followed the PRISMA recommendations, searching the PubMed, Web of Science, PsycInfo and SportDiscus databases. Original studies published in English were included, which analyzed the acute response of affective valence in adults using the Feeling Scale (FS) and heart rate in at least one session of continuous aerobic exercise with an average duration of 10 to 60 min. For the elaboration of the proposed exercise prescription based on SF, the analyzes were divided into two stages: in the first, the relationships between percentages of maximum heart rate (%HRmax); in the second, between the duration of the exercise and FS. The analyzes were carried out with the average data of each study and its conditions or subgroups, with the objective of determining the relationship between both variables (intensity and duration) and the affective valence. The findings confirmed the inverse relationship between the affective valence quantified by the SF and the intensity of the aerobic effort, but there was no consistent relationship with the duration. Thus, it was possible to propose zones of intensity compatible with the affective responses, calculating through linear regression to predict, from the score obtained FS, the intensity of continuous aerobic exercise as a function of SF: %HRMax = -4.761 x SF + 84,921. It is concluded that the applicability of using FS as a means of regulating exercise intensity facilitates the experience of a positive affective response, contributing to long-term adherence to exercise.
