Influence of Consecutive Strength- and Endurance Regimes on the Myonuclear Domain and Satellite Cell in the M. Vastus Lateralis of Old Healthy Men

Randomised training intervention.

Influence of consecutive training regime on the impact of the myonuclear domain and satellite cell

Sarcopenia

Despite that the muscle mass can be positively influenced by training, the loading with high weights and/or to the total exhaustion is for many old persons not possible.

Therefore we aim to enhance the myonuclei in the muscle fiber of old male subjects in a first phase by endurance training, in order to promote a more effective muscle growth in a second phase by resistance exercise.
