TI  - Effect of coingestion of fat and protein with carbohydrate feedings on muscle 
      glycogen storage.
PG  - 2187-92
AB  - Dietary guidelines for achieving optimal muscle glycogen storage after prolonged 
      exercise have been given in terms of absolute carbohydrate (CHO) intake (8-10 
      g.kg-1.day-1). However, it is of further interest to determine whether the 
      addition of fat and protein to carbohydrate feedings affects muscle glycogen 
      storage. Eight well-trained triathletes [23.1 +/- 2.0 (SE) yr; 74.0 +/- 3.4 kg; 
      peak O2 consumption = 4.7 +/- 0.4 l/min] undertook an exercise trial (2 h at 75% 
      peak O2 consumption, followed by four 30-s sprints) on three occasions, each 1 wk 
      apart. For 24 h after each trial, the subjects rested and were assigned to the 
      following diets in randomized order: control (C) diet (high glycemic index CHO 
      foods; CHO = 7 g.kg-1.day-1), added fat and protein (FP) diet (C diet + 1.6 
      g.kg-1.day-1 fat + 1.2 g.kg-1.day-1 protein), and matched-energy diet [C diet + 
      4.8 g.kg-1.day-1 additional CHO (Polycose) to match the additional energy in the 
      FP diet]. Meals were eaten at t = 0, 4, 8, and 21 h of recovery. The total 
      postprandial incremental plasma glucose area was significantly reduced after the 
      FP diet (P < 0.05). Serum free fatty acid and plasma triglyceride responses were 
      significantly elevated during the FP trial (P < 0.05). There were no differences 
      between trials in muscle glycogen storage over 24 h (C, 85.8 +/- 2.7 mmol/kg wet 
      wt; FP, 80.5 +/- 8.2 mmol/kg wet wt; matched-energy, 87.9 +/- 7.0 mmol/kg wet 
      wt).(ABSTRACT TRUNCATED AT 250 WORDS)
