Background and Objectives: It seems that exercise training and shortly after ingestion of green tea extract (GTE) fat oxidation increases The purpose of this study was to investigate the combined effect of short term GTE and a single bout of cycle ergometer upon plasma glycerol, fatty acids and insulin levels.
Subjects and Methods: Sixteen healthy volunteer men were recruited and divided into two equal groups; experimental group (n=8) and placebo group (n=8), respectively. They consumed three GTE or placebo capsules one day before and one capsule 90 min before a cycling protocol. Blood samples were collected from all participants before and after the protocol.
Results: Plasma glycerol, free fatty acids and insulin levels of experimental group were significantly higher after GTE consumption after post-exercise compared to placebo (P<0.05). While no significant differences were objesrved in the placebo group
Conclusion: Therefore, it seems that acute GTE ingestion could increase fat oxidation after post exercise conditions.
