Changes in V02peak, energy intake, anthropomorphic, and body composition (DXA) parameters, restricted to 18 breast cancer survivors completing the 12-week weight-loss intervention which included twice weekly personal trainer sessions. Median (range) values. p-values from Wilcoxon signed rank test, 2- tailed.
