AB  - The majority of football players succumb to fatigue towards the end of the game. 
      This study was designed to examine the influence of protein coingestion with 
      carbohydrate (CHO) vs. an isocaloric CHO supplement on subsequent running 
      capacity towards the end of a simulated football match. Six male amateur football 
      players participated in 3 trials applied in a randomized cross-over experimental 
      design. A laboratory-based, football-specific intermittent exercise was allocated 
      for 75 min interspersed with a 15-min recovery, immediately followed by run time 
      to fatigue (RTF) at 80% peak oxygen consumption. In each trial, prior to exercise 
      and during half-time, participants randomly ingested a placebo (PLC), 6.9% CHO, 
      or 4.8% CHO plus 2.1% protein (CHO-P) supplements matched for color and taste. 
      CHO-P resulted in longer RTF (23.02 +/- 5.27 min) than did CHO (16.49 +/- 3.25 min) 
      and PLC (11.00 +/- 2.80 min) (p < 0.05). Blood glucose was higher in CHO-P at the 
      point of fatigue (4.68 +/- 0.64) compared with CHO and PLC (3.92 +/- 0.29 and 3.66 +/- 
      0.36, respectively; p < 0.05). Ratings of perceived exertion were lower in the 
      CHO-P subjects at the onset of exercise and towards the end of intermittent 
      exercise when compared with the PLC and CHO subjects (p < 0.05). When protein was 
      added to a CHO supplement, subsequent running capacity following limited recovery 
      from intermittent exercise was enhanced. This improvement suggests that protein 
      coingestion may exert an ergogenic benefit upon endurance capacity during 
      intermittent activity.
