CAFFEINE INCREASES ANAEROBIC POWER
Kang, H-S., & Kim, B. R. (1999). Acute effects of caffeine intake on the 30-s Wingate Test performance. Medicine and Science in Sports and Exercise, 31(5), Supplement abstract 1348.
Whether a single caffeine ingestion affected anaerobic performance and serum catecholamine was investigated. Cyclists (N = 7) and students (N = 7) completed two 30-s Wingate Tests on two occasions, after either caffeine or placebo ingestion. A period of six days was allowed between trials.
Maximal anaerobic power and serum levels of both catecholamine and lactate at exhaustion were significantly increased after caffeine.
Implication. Anaerobic power is increased after a single administration of caffeine.
