Objective: The aim of this study was to identify the effect of acute caffeine intake on total ‌‌antioxidant capacity (TAC) and oxidative stress indices (MDA) in male volleyball players following one-session resistance exhaustive exercise.

 

 

 

Materials and Methods: Twenty male volleyball players (mean age 21.20±1.10 years, fat 10.75±2.78% and BMI 22.95±0.99 kg.m2) participated in a randomized, quasi-experimental, double-blind and repeated measured (three stages) design. Then, all subjects were allocated to two homogeneous groups (in order: 9 mg.kg-1.day caffeine or dextrose). All subjects participated in a single-session resistance weight-exercise (7 stations in 3 sets per station with 80% of 1-RM until exhausted). Blood samples were taken at three stages (baseline and 45 min after supplementation, and immediately after the exercise) were determined for changes in serum TAC and MDA.

 

 

 

Results: The results showed that the acute caffeine intake has no significant effect on the basal serum TAC and MDA (p≥0.05). Moreover, one-session resistance exhaustive exercise significantly reduced TAC (P≤0.05) and significantly increased MDA (p≤0.05). However, no significant differences in any of the measured variables between the groups were found immediately after resistance exercise (p≥0.05).

 

 

 

Conclusion: The present results show that acute caffeine consumption does not increase basal TAC and could not decrease the undesirable alterations of serum MDA induced by one-session of resistance exhaustive exercise in male volleyball players.
