Caffeine optimizes Zumba training benefits on functional performances in middle-aged women: a randomized trial study.
Study Goal
The researchers aimed to determine the effects of daily caffeine supplementation (100 mg/day) and 12-week Zumba training on functional performances in middle-aged women.
Results Summary
Caffeine supplementation alone and combined with Zumba training significantly improved functional performances, with the combined intervention showing the greatest benefits in mobility, gait speed, and lower body endurance strength.

The current study aimed to explore the effect of daily caffeine supplementation (100 mg/day) and 12-week of Zumba training on functional performances in middle-aged women. Eighty-five middle-aged women were randomized into 4 groups including control, Zumba training (ZT), caffeine supplementation (Ca) or caffeine-Zumba training (Ca + ZT) groups. Functional performances were assessed using 10 m Walk, Timed Up and Go, Functional Reach, and 30-Second Chair Stand tests. As results, ZT, Ca and Ca + ZT intervention programs showed a significant (p < 0.05) functional performances improvement. However, Ca + ZT group showed significant (p < 0.001) better scores in terms of mobility (95%CI [0.71, 1.43]), gait speed (95%CI [0.52, 1.71]) and lower body endurance strength (95%CI [-6.93, -1.92]), except for dynamic balance (95%CI [-9.41, -3.44]). In conclusion, 12-week of Zumba training improves functional performances in middle-aged women, and daily caffeine intake is an effective alternative for improving such performances. Supplementing caffeine (100 mg/day) to Zumba training was effective in boosting Zumba benefits on these functional performances.
