The effects of swimming training upon mechanical and metabolic properties of heart are investigated in two groups of male Sprague Dawley rats, fed ad libitum: a control group and a swimming group. The chronic training improves myocardial mechanical performances: coronary flow, cardiac output and left ventricular pressure are increased in isolated working conditioned heart preparations. Oxygen consumption and work performance are greater than in control group, but cardiac efficiency is not significantly different between the two groups. Intrinsic conditioned heart rate is lower than in control heart. Endogenous triglycerides and exogenous FFA utilization rates are increased in trained perfused heart. We found a significant correlation (P less than 0,01) between exogenous FFA utilisation and coronary flow.
