| Popis: | We used Drosophila melanogaster as an animal model system to study the impact of exercise training initiated early in life on cardiac function using a well-established model of inherent myogenic properties of the heart and discussed the changes on myosin, a myocardial contractile protein. We also explored the effect of early physical exercise on organismal aging by analyzing the wake-sleep pattern using a Drosophila activity monitor system. We found that a variety of arrhythmias are part of the heart spectrum in old flies after a lifetime of physical exercise as evidenced by reducing the incidence of fibrillations and increasing the occurrence of bradycardias. Maintenance of myocardial myosin levels may be an underlying contributor to these exercise-induced improvements in cardiac function at an advanced age. Moreover, we found that exercise training resulted in improved sleep quality by ameliorating age-related sleep inefficiency, fragmentation and sleep consolidation. |
