Effects of Zumba® and different walking workouts on female cortisol and DHEA-S production
AbstractPurpose: Aims of our study were to characterize both heart rate and hormonal responses elicited by three different fitness disciplines: outdoor walking training, Zumba®, and walking training on magnetic treadmill. Methods: Fifteen healthy trained women (42 ± 7 yr) performed three different workouts conducted by the same instructor. Salivary samples were collected before and after each workout, at 11 p.m. and at 7 a.m. of the following day, while a beat-to-beat heart rate recording was executed during each workout. Saliva was also collected during a non-training day. Cortisol and dehydroepiandrosterone sulfate (DHEA-S) were measured in salivary samples. Results: Workouts have been shown able to affect physiological trend of LogCortisol according to intensity: as highest was workout intensity as highest was LogCortisol at 11 p.m. The same has been shown for LogDHEA-S except for outdoor walking training that has not been able to affect salivary LogDHEA-S. Time elapsed at both 60-69% maximal heart rate (HRmax; r=0.301, p=0.05) and 80-89% HRmax (r=-0.328, p=0.003) have been shown correlated with LogCortisol to LogDHEA-S ratio. Conclusions: The knowledge of acute and delayed hormonal effects of fitness disciplines is very important to optimize health promotion and maintenance of midlife trained women, near to menopausal transition.
