Mood states have been shown to change before and after a workout, such as an increase in energy, feeling less anxious, and a sense of rejuvenation. These mood states have been linked with positive behavioral health outcomes. Previous researchers also have explored how specific modes of exercise can influence behavioral health. However, there has not been a cross-examination of these exercise modes. PURPOSE: The purpose of this study was to evaluate the effects of different exercise modes on post-exercise behavioral responses. METHODS: An invitational email was sent out to 500 full-time undergraduate students (18-23 years old) via random sampling. Potential respondents were provided with survey instructions and online consent for participation. Ultimately, 17 eligible respondents who performed 7.27 ± 2.98 hours of exercise per week volunteered to participate in the survey. Respondents reflected on mood states pre- and post-exercise with different modes (anaerobic, resistance, aerobic, and mobility). The positive and negative affect schedule (PANAS) scale was used to score mood states. A factorial analysis of variance (p ≤ 0.05) was used to compare mood states between different modes of exercise and pre-and post-exercise RESULTS: There was a significant difference (p = 0.00) between pre-and post-exercise mood states for both positive affect (pre: 26.27 ± 1.58, post: 38.20 ± 1.34) and negative affect (pre: 13.66 ± 0.59, post: 10.95 ± 0.33). However, there were no significant differences between modes of exercise (p = 0.53 - 0.83). CONCLUSION: The primary findings of the study were that positive affect increased, and negative affect decreased pre- to post-physical activity for all modes of exercise. Previous research that documented similar effects of exercise and physical activity on mood states, suggested that hormonal levels, such as cortisol may influence these mood states. In future research, it would be beneficial to examine mood states at the time of exercise instead of retrospectively. Additionally, a larger sample population would increase the statistical power of the results.
