- W1970435087 abstract "Abstract Hearts of rats conditioned by a moderate swimming program for 8 weeks were compared with hearts of sedentary animals. Hearts of conditioned rats had greater mechanical responses to tachycardia and to increases in preload and afterload, in part because of improved coronary blood flow and oxygen delivery. Energy stores and intermediary metabolism could not account for improved performance of conditioned hearts. Changes in the properties of myocardial contractile proteins with conditioning were characterized by increased adenosine triphosphatase (ATPase) activity and rates of superprecipitation of actomyosin and by alterations in the availability of sulfhydryl groups at the active site of myosin. Hearts of conditioned rats were partially resistant to hypoxia. During hypoxia they converted chemical energy to external work with greater efficiency than hearts of sedentary rats. The studies indicate that a moderate conditioning program in rats improves potential aerobic cardiac performance. Factors in this improvement include increased capacity for coronary flow and oxygen delivery and higher levels of actomyosin and myosin ATPase activity. Conditioning also confers partial resistance to hypoxia, apparently as a result of improved mechanisms of energy utilization." @default.
