Purpose This study compared the acute effects of an exergame-based calisthenics (EXG) session versus a traditional calisthenics (TC) session on state anxiety levels in healthy adult men, and compared the mean heart rate, number of repetitions performed, enjoyment, and affective valence reported by the participants between sessions. Methods Thirty-six young adult men performed two 30-min sessions of physical exercise in random order (EXG and TC). The same exercise protocol was used for each session; however, the TC session was guided by an exercise science professional. State anxiety was assessed before and immediately after each session. Heart rate was monitored during the sessions. Enjoyment and affective valence were assessed immediately after the sessions. In addition, the number of repetitions performed was recorded. Results There was no significant interaction between sessions (EXG vs. TC) and time (pre vs. post-session) ( p = 0.102), no significant effect of session ( p = 0.587), and no significant effect of time ( p = 0.121). Participants presented a higher mean heart rate (+ 3.5%, p = 0.020) and number of repetitions performed (+ 43.7%, p < 0.001) in the TC session compared with the EXG session. There was no difference in enjoyment ( p = 0.804) and affective ( p = 0.195) valence between the EXG and TC sessions. Conclusion The EXG and TC sessions did not reduce state anxiety levels. Nor did they increase enjoyment or affective valence in healthy young adult men. However, the TC session evoked a higher mean heart rate and higher training volume than the EXG session.

Considering that exposure to unpleasant pictures taken from the International Affective Pictures System (IAPS) has a more significant impact on anxiety than exposure to pleasant and neutral pictures, we investigated changes in state anxiety levels and heart rate responses in healthy women following exposure to three blocks of unpleasant pictures from the IAPS. Thirty-seven healthy women visited the lab three times, separated by a gap of 24–72 hours. Anxiety levels were assessed using the State Anxiety Inventory before and after participants viewed the blocks of unpleasant IAPS pictures, while the heart rate was continuously monitored throughout each session by a heart rate monitor. We found extreme evidence (BF10 = 7.53*108) for the changes in the participants’ state anxiety after viewing IAPS unpleasant pictures, although there was ambiguous evidence (BF01 = 2.642) favoring similar changes in state anxiety and ratings of pleasure (BF01 = 1.567), arousal (BF01 = 2.609), and dominance (BF01 = 1.954) between the three blocks of unpleasant pictures used. Moreover, we found moderate evidence (BF01 = 7.449) favoring similar mean heart rates between the three blocks of unpleasant pictures. These findings reveal that exposure to unpleasant pictures can act as an anxiogenic stimulus used to induce experimental anxiety.
