Abstract

Purpose: Chocolate milk (CM) may have ergogenic effects as a short-term recovery aid. CM may stimulate glycogenesis, protein synthesis and aid in hydration. The aim of this study was to test CM’s efficacy as a recovery aid, over 24 hours in tennis.
Methods: Eight male university tennis players (Mean ± SD: age, 19.2±1.0 years; mass, 72.0±10.1Kg; BMI, 21.8±2.1kg/m2; VO2Max, 47.6±3.7ml.kg-1.min-1) participated in a randomised cross over design. Participants completed performance tests including a tennis skills test and exercise to exhaustion. After which, 800ml of CM (or water) was consumed within 2 hours. Post consumption blood glucose levels were measured. After a recovery period (24hours) participants ran through the same protocol. Over their testing participants completed in-depth food and muscle soreness diaries.
Results: There was no significant different in the consecutive bout for repeated sprints and tennis skills between the water and CM condition. There was a significant difference in time to exhaustion between water (466±201 seconds) and CM (660±125 seconds) in a consecutive bout (p=.002). Despite working for longer in the CM condition there was no significant change in physiological or psychophysiological disturbance (blood glucose, lactate, RPE and HR). Post consumption blood glucose levels were significantly elevated post CM consumption (p≤0.001) and a three-day muscle soreness diary reported significantly lower DOMS.
Conclusion: Chocolate milk did significantly improve time to exhaustion in tennis with no significant changes in physiological disturbance or psychophysiological during exercise. Moreover, muscle soreness was significantly reduced after the intake of CM. It can be concluded that CM does appear to have an ergogenic effect as a recovery aid, in a sample of eight male university tennis players.
