Purpose: To evaluate the effects of the adapted sport “adapted dance” (AdD) on the mood state and autonomic nervous function in healthy elderly people. Methods: Four elderly men and women (age: 71.8 ± 2.5 years) participated in an AdD. Ratings of perceived exertion (RPE) and heart rate variability (HRV) were measured during AdD, and the Profile of Mood States-Short Form 2nd Edition (POMS2-SF) was used to evaluate participants before and after AdD. Results: Mean HRV during AdD was 83.8 ± 2.5 bpm and mean RPE was 12.5 ± 1.0. After participating in AdD, the POMS2-SF scores for Anger-Hostility (p<.05) decreased, while those for Vigor-Activity (p<.05) and Friendliness (p<.05) increased. Furthermore, the autonomic nervous function of all participants exhibited a relaxed state. Conclusion: The AdD intervention for healthy elderly people led to short-term improvement in mood states, as well as an increase in their relaxed state, even though exercise intensity was low.
