In this study we investigated affective changes during Zumba fitness program exercise with varied intensity, as measured by a smartwatch. Sixteen college students (4 males and 12 females) participated in two single-session Zumba fitness programs at low and moderate intensities separated by a one-week interval. During exercise, participants' heart rate (HR) and their responses to the Felt Arousal Scale (FAS) and the Feeling Scale (FS) were measured seven times (pre-exercise, warm-up, merengue, reggaeton, salsa, cumbia, and cool-down) using tailor-made applications on a smartwatch. Additionally, pre- and post-exercise affect was measured by the PANAS-X, which showed enhanced positive affect and reduced negative affect following exercise. Feelings and arousal during exercise were activated, irrespective of exercise intensity, but positive effects were more prominent at the higher (moderate) exercise intensity level. By adopting wearable technology, we were able to measure real-time affect changes during exercise, and we demonstrated the particular affective benefits of a moderate intensity Zumba Fitness program.
