A study was conducted to examine the effects of active recovery (AR), massage (MR), and cold water immersion (CR) on performance of repeated bouts of high-intensity cycling separated by 24 hours. A sample of physically active men aged 18-30 were randomly assigned to one of four groups. Each group performed an intense 18 minute cycling work out after which each underwent a 15 recovery period. The first group (AR) continued to cycle at a low level, the second group (MR) received leg massage, the third group (CR) immersed their legs in a bath of cold water. The last group simply sat and rested. The next day the subjects did the same intense 18 minute cycling workout. Each exercise was done on a cycle ergometer so that the work level (measure in kilojoules) was calculated for each. The researchers found that on the second day, that there was no difference in the performance level of the subjects in the AR, MR and CR, but that the subjects who just sat in a chair to rest did less work than the other groups.
