AB  - BACKGROUND: Caffeine supplementation (CAFF) has an established ergogenic effect 
      on physical performance and the psychological response to exercise. However, few 
      studies have compared the response to CAFF intake among athletes of different 
      competition level. This study compares the acute effects of CAFF on anaerobic 
      performance, mood and perceived effort in elite and moderately-trained 
      recreational athletes. METHODS: Participants for this randomized, controlled, 
      crossover study were 8 elite athletes (in the senior boxing national team) and 10 
      trained-recreational athletes. Under two experimental conditions, CAFF 
      supplementation (6 mg/kg) or placebo (PLAC), the athletes completed a Wingate 
      test. Subjective exertion during the test was recorded as the rating of perceived 
      exertion (RPE) both at the general level (RPE(general)) and at the levels 
      muscular (RPE(muscular)) and cardiorespiratory (RPE(cardio)). Before the Wingate 
      test, participants completed the questionnaires Profiles of Moods States (POMS) 
      and Subjective Vitality Scale (SVS). RESULTS: In response to CAFF intake, 
      improvements were noted in W(peak) (11.22 +/- 0.65 vs 10.70 +/- 0.84; p = 0.003; 
      [Formula: see text] =0.44), W(avg) (8.75 +/- 0.55 vs 8.41 0.46; p = 0.001; 
      [Formula: see text] =0.53) and time taken to reach W(peak) (7.56 +/- 1.58 vs 
      9.11 +/- 1.53; p <  0.001; [Formula: see text] =0.57) both in the elite and 
      trained-recreational athletes. However, only the elite athletes showed 
      significant increases in tension (+ 325%), vigor (+ 31%) and SVS (+ 28%) scores 
      after the intake of CAFF compared to levels recorded under the condition PLAC 
      (p <  0.05). Similarly, levels of vigor after consuming CAFF were significantly 
      higher in the elite than the trained-recreational athletes (+ 5.8%). CONCLUSIONS: 
      CAFF supplementation improved anaerobic performance in both the elite and 
      recreational athletes. However, the ergogenic effect of CAFF on several mood 
      dimensions and subjective vitality was greater in the elite athletes.
