Maryam Shamsi MSc Student in Physical Education, University of Tabriz, Tabriz, Iran Journal Article 2018 11 28 The aim of this study was to evaluate the effect of time-consuming chocolate milk on some muscle damage indexes and performance of resistance exercise in male athletes. 33 male student-athletes 3±21 years old , Weight 81/7±65/67 body fat percentage 40/4±78/10% are recruited and randomly assigned to 3 groups, including control group(n=11), Group chocolate milk supplementation half an hour before resistance exercise (n=11) and Group supplementation chocolate milk immediately after exercise (n=11). Resistance exercise protocol includes movements of leg press, bench press, and the instep with 70% of one repetition maximum in 3 sets of 10 repetitions were performed. Blood sample were collected to measure index Creatine kinase (CK), Lactate Dehydrogenase (LDH) and serum lactate (LA) in 3 stages: Before, 45 minutes of activity and 24 hours after exercise. For data analysis, analysis of variance with ANOVA 3×3, ANOVA with Bonferroni test to check if the difference was statistically significant and meaningful level for all tests Alpha was set up to 0/05. In Group DA, the amount of lactate lower compared to DB (P=0/043) and CL (P=0/008) was observed in the second stage of sampling. The amount of CK Group DA 24 hours of exercise a significant decline compared to the control group (P=0/024) But no significant changes in serum LDH levels (P=0/54) to consider Cacao milk consumption reaches of sport activities can be effective in reducing muscle damages.
