SUMMARY:

Introduction: Physical inactivity is the biggest public health problem of the 21st century and a large portion of the population cannot reach the recommended levels. Worldwide> 30% of adults and 50% of Brazilians report lower numbers than minimum exercise recommendation for health promotion. Objective: To evaluate possible transverse and longitudinal associations between acute affective responses in two aerobic exercise conditions and the implicit association, physical activity behavior and sedentary behavior at baseline and after a period of six months. Methods: The study is characterized as prospective analytical observational with a cross-over randomization where participants were tested under two exercise conditions (moderate intensity and self-selected intensity), and a longitudinal correlation performed through the level of physical activity and behavior sedentary. The sample consisted of sedentary subjects of both sexes, aged 18-59 years. The effects of independent variables (perceptual affect responses, implicit and explicit attitudes) on dependent variables (future participation in physical exercise, level of physical activity and sedentary behavior) were verified. Participants underwent assessment procedures at baseline and after 6 (six) months. The normality of the data will be verified by the Shapiro-wilk test. Pearson's or Spearman's correlation was used to verifying the relationship of affective responses, implicit and explicit attitudes to preference and tolerance responses, future physical activity behavior, sedentary behavior, and future intention. Linear regression was used to verify the prediction of future behavior in physical activity. For data analysis, we used the software SPSS version 20.0. The significance level established was p <0.05. Results: Positive correlations were found between the implicit association with mean affect at moderate intensity (r = .29; p = .038) and with moderate and vigorous physical activity (r = .35; p = .014). In the linear regression analyses, the results show that each unit of increase in the implicit association represented a 0.6 minute increase per day in moderate and vigorous physical activity (beta = 0.6; SE = 0.28; p =, 034) and a 0.5-point increase in the affective response of moderate-intensity exercise subjects (beta = 0.5; SE = 0.26; p = .038), both change ratios being explained by 7%. We found that a unit of increase in the level of preference at baseline exercise intensity represented a 1.9-minute increase per day in moderate and vigorous physical activity after 6 months (beta = 1.9; SE = 0.50; p = .002), change is explained by 47%. Increasing the tolerance level by one unit at baseline exercise intensity represented a 1.3 minute increase per day in moderate physical activity (beta = 1.3; SE = 0.50; p = .020) such relationship explained by 28% in the regression model. Conclusion: A greater implicit association for physical activity was associated with more positive affective responses in moderate-intensity exercise and a greater amount of moderate and vigorous physical activity at baseline.
