Short-term water-based aerobic training promotes improvements in aerobic conditioning parameters of mature women.

Aging is accompanied by a decrease in aerobic capacity. Therefore, physical training has been recommended to soften the effects of advancement age. The aim of this study was to assess the effects of a short-term water-based aerobic training on resting heart rate (HRrest), heart rate corresponding to anaerobic threshold (HRAT), peak heart rate (HRpeak), percentage value of HRAT in relation to HRpeak and test duration (TD) of mature women. Twenty-two women (65.91 ± 4.83 years) were submitted to a five-week water-based interval aerobic training. Aerobic capacity parameters were evaluated through an aquatic incremental test. After training, there was an increase in TD (16%) and HRAT percentage in relation to HRpeak (4.68%), and a reduction of HRrest (9%). It is concluded that a water-based aerobic interval training prescribed through HRAT of only five weeks is able to promote improvements in aerobic capacity of mature women.
