Abstract

Objective. Affective response is an important predictor for future exercise practice adherence and measuring affect is included in the recommendations for exercise prescription, along with other physiological factors such as heart rate and the Rating of Perceived Exertion. Up until now, it has been confirmed that one-dimensional measures are not able to reflect the full spectrum of affective response to exercise, for the conventional measures do not catch the dynamic affective response to a training bout and only describe the differences between the states before and after the exercise. One of the two-dimensional measures that could be applied during exercise and is able to trace the affective response dynamically is the circumplex model of affect in exercise-related contexts. The aim of the present thesis was to analyze a dose-response of affective valence and activation during a CrossFit training program (WOD) and to study the changes in well-being and the emotional domain; the project is of a translational nature and focuses specifically on interindividual differences and the representation of affective valence mapped on the circumplex model of affect. Methods. Initially, to analyze existent scientific evidence on the application of the circumplex model of affect in exercise domain a systematic literature review was conducted, based on experimental studies that analyzed affective valence and activation on samples of different age groups and in various exercise regimens, always by the means of the circumplex model of affect. Secondly, an experimental study was conducted with a sample of 33 CrossFit exercisers in CrossFit boxes in Lisbon. Affective valence, activation, well-being, emotional domain and heart rate variability were analyzed via questionnaires and a heart rate monitor. Descriptive statistics, T-tests and Pearson correlation were conducted as part of statistics analyses. Results. In the systematic literature review 22 articles on the subject were included. All the studies used the circumplex model of affect as a measure of affective valence and activation. There was a significant improvement in affective valence comparing before and after the training bout, as well as a consistent pattern of decreasing pleasure approaching the anaerobic threshold. It seems that exercise programs and aerobic exercise with self-selected intensity promote positive activation in various populations and age groups, with a strong tendency for interindividual variability. Strength and resistance training, according to the few existing studies, also seems to promote the highest activation levels during training and a positive affective response post-training, both in training bouts with self-selected and imposed intensity (Focht, 2002). According to Arent et al. (2005), affective response is more positive at moderate intensities, in contrast to low and high intensities. The result of the experimental study did confirm that affective response was better when comparing before and after the training bout. Positive associations were found between Feeling Scale and the final well-being, as well as positive activation. No significant associations were found between Felt Arousal Scale measures and post training well-being.
