  1. aMean ± SEM for n = 11 ATP (400 mg ATP/d taken 30 min prior to exercise) and n = 10 placebo supplemented participants.
  2. bProbability of treatment by time difference between the placebo and the ATP treatments over the 12-week study. The mixed model ANOVA in SAS® was used with the main effects of treatment, time and treatment by time, with the value for week 0 used as a covariate.
  3. #Significantly different than corresponding placebo, t-test (p < 0.05).
