TI  - Muscle glycogen supercompensation: absence of a gender-related difference.
PG  - 533-8
AB  - Recently it has been reported that women do not have the capacity to accumulate 
      supranormal levels of muscle glycogen when subjected to a carbohydrate (CHO) 
      loading regimen [Tarnopolsky et al. (1995) J Appl Physiol 78:1360-1368]. Since, 
      in this study, CHO intake relative to body mass in the female subjects was much 
      lower than that in males, our primary aim was to re-examine this issue using 
      subjects fed comparable amounts of CHO. Endurance-trained female and male 
      subjects ingested 12 g CHO x kg(-1) lean body mass day(-1) in conjunction with 
      the cessation of their daily physical training. A 3-day exposure to this diet 
      resulted in a marked rise in muscle glycogen levels from [mean (SD)] 108 (15) 
      mmol x kg(-1) wet weight to 193 (14) mmol x kg(-1) wet weight and 111 (16) m mol 
      x kg(-1) wet weight to 202 (20) mmol x kg(-1) wet weight in the female 
      participants during the post-menstrual and pre-menstrual phases of their 
      menstrual cycle, respectively, and from 109 (27) mmol x kg(-1) wet weight to 183 
      (25) mmol x kg(-1) wet weight in males. We conclude that (1) female athletes have 
      the capacity to accumulate supranormal levels of muscle glycogen, and (2) when 
      exercise-trained males and females are fed comparable amounts of CHO relative to 
      lean body mass, there is no gender-related difference in their ability to 
      accumulate supranormal levels of muscle glycogen.
