Comparing Land-based and Aquatic Reduced Exertion High Intensity Interval Training in Sedentary Young Adults

Previous research has found improvements in performance (VO2max) and clinical (insulin resistance) with cycling REHIIT. In some populations (e.g. obese, arthritic) aquatic exercise is a safer, more enjoyable option. However, to date, no study has yet examined whether aquatic REHIIT confers the same benefits as land-based REHIIT. Therefore, the purpose of this study is to determine whether there are significant differences in clinical and performance outcomes between a land-based and comparable aquatics based Reduced Exertion High Intensity Interval Training (REHIIT) protocol.
