The purpose of this research was to study the effect of caffeine supplement ingestion on Free Fatty Acid (FFA) and lactate (LA) in young taekwondo players after specific interval exercise. 18 young taekwondo players were selected with the averages of age 18.33± 1.3 yrs, weight 65.50±4.75 kg and then divided in 3 groups (6 persons per group), randomly. Subjects participated in two -phase specific interval activity protocol (before and after caffeine ingestion) with 48 hours rest in between. First group, performed specific interval activity in 6 minute, but second group, performed two-phase of specific interval activity in 6 minute with an hour active recovery between them. The third group performed same activity in three phases. Blood samples were taken in two phases (before and after caffeine ingestion), each phase in three steps (immediately after three phases of test). Data were analyzed by one way ANOVA and LSD in significant level P≥0.05. Results showed non-significant increase in FFA and blood lactate, except lactate changes in first group. Based on our findings it seems that caffeine supplement did not show any significant effect on FFA, lactate or metabolisms in young taekwondo players. As such caffeine ingestion did not demonstrate any increased fat lipolysis or any effect on lactate accumulation in taekwondo players.
