Methods: We have chosen eight male physical education students (age: 22.9±1.7 yr, body fat: 12.7±1.9, and BMI: 23.1±1.7 kgm3) in a randomized, double-blind, placebo-controlled, and crossover method design. the exercise protocol was including 7 exercises whole-body movement that performed in 75% 7RM for 3 set with 10 repetitions in each set. Participants consumed supplements or placebo 30 minutes before exercise. The supplement was a single scoop (6.5 gr) and the placebo was 6.5 gr maltodextrin. Blood samples were taken before, immediately post, and 1hour post-resistance exercise to analyze Creatine Kinase (CPK) and Lactate dehydrogenase (LDH). For analysis of data, the repeated-measures ANOVA and Bonferroni tests were used.
Results: The results had shown that there were no significant differences in acute muscle inflammation responses between C4 consumption and placebo-controlled men. Lactate dehydrogenase levels, immediately after ingestion and 1 hour after resistance exercise don’t show any differences between placebo and supplement conditions (p>0.05). However, the rise of Creatine Kinase after exercise was higher in placebo-controlled than supplement conditions (p<0.05).
Conclusion: According to the results of this study, the C4 supplement has no effective response on reducing lactate dehydrogenase accumulation after resistance exercise but can affect the decrease of creatine kinase levels, So this supplement improves the recovery conditions of the body after exercise.
