Abstract

Some evidence indicates that caffeine consumption before exercise may affect muscular damage. The aim of this study was to investigate the effects of caffeine consumption (6mg/kg) following a session of resistance exercise on creatine kinase (CK) and lactate dehydrogenase (LDH) in active men. 20 male physical education students (age 21.22±1.25 years, height 175.13±6.88 cm, weight 69.22±7.10 kg and BMI 22.21±2.21 kg/m2) were randomly assigned to placebo (n=10) and caffeine (n=10) groups. One hour before resistance exercise, subjects received caffeine or placebo in a double-blind manner. Resistance exercise included a circuit exercise in 5 stations (each station 3 sets); each set was performed by 75% 1RM in 8 to 10 repetitions. Blood samples were collected before, immediately after, 24 and 48 hours after the exercise. The results showed a significant increase in enzyme levels of CK (P=0.013) and LDH (P=0.001). However, these changes were not different between the two groups (P≥0.05). It seems that caffeine (6mg/kg) consumption before resistance exercise cannot reduce muscle damage indexes in blood.
