Overview
Brief Summary
There is a decrease in cardiovascular and neuromuscular functions, which leads to reduced performance with advancing age. Physical activity provides health benefits, prevents and treats cardiovascular and neuromuscular disease. The aim of this project is to describe cardiovascular and neuromuscular function in active and sedentary subjects of different ages.
Detailed Description
With advancing age, there is a decrease in cardiovascular and neuromuscular functions, which leads to reduced performance and increases the likelihood that older people will lose their independence. Physical activity provides health benefits, prevents and treats cardiovascular and neuromuscular disease. Indeed, recent data support the idea that it is fitness level, not age that explains physiological responses to exercise. However, although there are data about how quickly cardiovascular and neuromuscular functions decline throughout life, less is known on the extent physical activity can help mitigate the loss of these functions. The aim of this project is therefore to describe cardiovascular and neuromuscular function in active and sedentary subjects of different ages.
