Involutional changes and anabolic processes in people aged 60-65 undergoing strength and endurance circuit health training

Abstract

Background: One of the effects of comprehensive physical activity is the increase in muscle mass and reduction of fat mass. With this regard, particularly effective is circuit training, which involves the majority of the main muscle groups, also including elements of endurance training. It should be mentioned that one of the involutional processes that takes place during aging is the reduction of muscle mass. Method: Changes in body composition were studied in people aged 25-30 and 60-65 undergoing circuit health training. Then, it was measured whether the differences between the groups were statistically significant and whether there was a correlation between age and individual body composition parameters. Results: There were significant differences in the percentage of fat mass between these groups. There were no significant differences regarding changes in fat mass, muscle mass or percentage muscle mass between these groups. Conclusions: The results allow to state that physical activity in old age helps to prevent involution changes in muscles. The results of the presented study may indicate a new direction in research on neuromuscular plasticity in the elderly.
