Text: After 6 months, a significant increase in work capacity was observed only in the training group (from 4. 462 + / -1. 095 to 5. 752 + / -1. 749 kilopond-meters [Kp-m], P <. 01), not in the control group (from 4. 375 + / -1. 143 to 4. 388 + / -1. 199 Kp-m), whereas left ventricular volumes had increased in the control group (end-diastolic volume, from 94 + / -26 to 99 + / -27 mL/m2, P <. 01 ; end-systolic volume, from 62 + / -20 to 67 + / -23 mL/m2, P <. 01) but not in the training group (end-diastolic volume, from 93 + / -28 to 92 + / -28 mL/m2, P = NS ; end-systolic volume, from 61 + / -22 to 57 + / -23 mL/m2, P = NS).
