Changes in VO2peak, anthropomorphic, and body composition (DXA) parameters for 9 women complementing a 24-week weight-loss intervention with twice weekly personal trainers during initial 12 weeks only but provided continued access to exercise facility weeks 13–24. Median (range) values. p-values from Wilcoxon signed rank test, 2-tailed.
