Abstract

The purpose of this study was to examine the effect of massage on blood lactate levels in trained male runners following a maximal treadmill run. Twenty-two male distance runners performed a maximal aerobic run on a motor-driven treadmill, at 9 mph and a 2 1/2% grade increase every minute until exhaustion. Fifteen of the subjects were randomly selected for either an active bicycle recovery (pedaling at 40% VO2max), or to receive a massage. A third group served as a control and lay supine during recovery. The three recoveries lasted 20 min. Venous blood was collected during the recovery at 3, 5, 9, 15, and 20 min post-exercise and analyzed for blood lactate concentration. At rest and 3 min post-exercise, the three groups were not statistically different, however, at 5 min post-exercise, the massage group displayed a significant difference compared to the control group. At 9 min post-exercise, the three groups were not statistically different, however, at 15 min post-exercise, the bicycle group was different compared to the control group. At 20 min post-exercise, there was no statistical difference between groups. Dependent t-test analysis was performed each recovery interval to compare the rate of recovery within each group. All three groups displayed a significant difference between resting lactate levels and 3 min post-exercise. Until min 9 of recovery, only the bicycle recovery has a decrease in lactate concentration. The three groups displayed significant differences between-8 min to 15 min and 15 min to 20 min post-exercise. The Results of this study suggest the bicycle group started clearing lactate from the blood at 5 min post-exercise, while the massage and control group started clearing lactate at 9 min post-exercise and that the massage group's lactate level declined at a similar rate as the control group.
