Among men only , significant differences were found in VO@ ( rehabilitation : @ mL/min/kg -LSB- standard deviation ( SD ) @ -RSB- vs @ mL/min/kg -LSB- SD @ -RSB- and usual care : @ mL/min/kg -LSB- SD @ -RSB- vs @ mL/min/kg -LSB- SD @ -RSB- , P = @ ) , total exercise time ( rehabilitation : @ seconds -LSB- SD @ -RSB- vs @ seconds -LSB- SD @ -RSB- and usual care : @ seconds -LSB- SD @ -RSB- vs @ seconds -LSB- SD @ -RSB- , P = @ ) , and the mental component scale ( rehabilitation : @ points -LSB- SD @ -RSB- vs @ points -LSB- @ -RSB- and usual care : @ points -LSB- SD @ -RSB- vs @ points -LSB- SD @ -RSB- , P = @ ) .
