TI  - Effect of CHO loading patterns on running performance.
PG  - 598-606
AB  - This study examined the influence of 3-day isoenergetic carbohydrate (CHO) 
      loading with different glycemic index (GI) and glycemic load (GL) meals on 
      running performance and metabolic responses. With a randomized crossover design, 
      nine male runners performed a 1-h run at 70% VO2max followed by a 10-km 
      performance run after a 3-day diet adaptation, which involved different GI and GL 
      meals [CHO intake (%), GI, and GL per day were 73%, 80, and 553 for the high GI 
      and high GL (HH); 73%, 36, and 249 for the low GI and low GL (LL); and 31%, 79, 
      and 227 for the high GI and low GL (HL), respectively]. There were no differences 
      in the time to complete the 10-km run between the two high-CHO trials; however, 
      the performance in the LL trial was improved as compared to that in the HL trial 
      (mean +/- SEM: HH vs. LL vs. HL: 51.3 +/- 5.3 vs. 48.6 +/- 1.3 vs. 55.3 +/- 6.9 
      min). It appears that the amount, rather than the nature, of the CHO consumed 
      during the 3-day isoenergetic CHO loading may be the most overriding factor on 
      subsequent metabolism and endurance run performance.
