摘要: This study used the meta-analytic approach to examine effects of caffeine ingestion on exercise testing. Forty double-blind studies with 76 effect sizes (ES) met inclusion criteria. The type test was classified as endurance, graded, or short-term. In comparison placebo, improved outcome by 12.3 % (95 CI, 9.1 15.4), which equivalent an overall ES 0.41 0.31 0.51). Endurance significantly (P < 0.05) more than either graded short-term exercise. When protocol examined, time-to-exhaustion (Tlim) protocols had a greater non-Tlim protocol(s). results from this meta-analysis confirm ergogenic caffeine, particularly for endurance testing that use Tlim protocols.
