Exercise Addicted Subject Show Positive Affective Responses Both Moderate And Intense Exercise

Abstract

The possible differences in affective responses to moderate and intense exercise in exerciser’s addiction subjects are not reported in the literature and this result can help elucidate the reasons for the deployment exercise dependence. PURPOSE: Investigate the affective responses of exercise addiction subjects and controls in moderate and intense exercise. METHODS: 17 male subjects (34.35±5.70yrs; 73.15±9.36kg; 1.75±0.07m; 24.78±2.51kg/m2; 13.17±4.73%FatMass), were distributed into a control group (n = 10) composed of runners without exercise addiction symptoms and an exercise addiction group (n=7) composed of runners with exercise addiction symptoms. The subjects were submitted to two treadmill tests separated by 7 days: 1) 60%Vpeak; 2) 85%Vpeak. For these conditions, the subjects answered a Subjective Exercise Experiences Scale (SEES) in the following time-courses: baseline (B), immediately after (IA) and 30 minutes after finishing of the exercise (R). To evaluate the affect during effort, a Feeling Scale was recorded at last minutes of exercise to both intensities. The data were compared by two-way ANOVA with post-hoc Duncan test, with significance p≤0.05. The protocol was approved by Unifesp Ethics Committed (#2.096.523). RESULTS: At 60%Vpeak, we not observed differences in SEES scale. At 85%Vpeak, the Fatigue subscale show similar responses between the groups, were an increased in IA when compared to B (p<0.001 to both). The feeling Scale results show that to control group, when 60%Vpeak was compared with 85%Vpeak intensity, the first one intensity was pleasurable, while the second one was unpleasurable (3.10±2.33 vs -1.90±3.51; p=0.002 respectively). To the exercise addiction group, both intensities was classified as pleasurable (3.00±1.82 vs 1.00±4.43; p=0.13). CONCLUSION: The data suggest that both exercise intensities moderate and intense (independent of fatigue state) are capable to promote well-being and pleasure in exercise addiction subjects, while to the controls group, feeling pleasure was observed only in moderate intensity.
