Abstract

This study examined the impact of caffeine ingestion on field hockey skill performance following high-intensity fatigue. Thirteen male hockey players (mean age=21.1 +/- 1.2 years) performed hockey sprint dribble and ball handling tests at rest and after a bout of total body fatigue (90% maximal capacity) following caffeine (5mg/kg) or placebo ingestion. Sprint dribble times were slower postfatigue compared with rest but were significantly faster postfatigue with caffeine compared with postfatigue with placebo ingestion (P<0.01). Ball handling scores were higher at rest compared with postfatigue, but scores postfatigue were higher following caffeine than placebo ingestion (P<0.01). Rating of perceived exhaustion (RPE) was lower (P<0.01) and readiness to invest physical (P<0.01) and mental effort (P=0.01) were significantly higher in the caffeine condition. Caffeine ingestion may therefore be effective in offsetting decrements in skilled performance associated with fatigue. Verf.-Referat
