REE showed group differences in posttraining conditions ( the @-week group vs. the control group , @ vs. @ kcal/die , and the @-week group vs. the control group , @ vs. @ kcal/die , P = @ ) , but RHR decreased ( pre-program vs. post program : @ vs. @ beat/min , P = @ ) and VO ( @peak ) significantly increased ( pre-program vs. post program : @ vs. @ mL/kg/min , P = @ ) in the @-week group compared to the control group .
