Exercise capacity refers to the maximum amount of physical exertion or exercise that an individual is able to sustain over a period of time. It is often measured using indicators such as VO2 max, which is the maximum rate of oxygen consumption during exercise, and is considered a strong predictor of overall cardiovascular health and fitness. Research in this area aims to understand the factors that influence exercise capacity, such as genetics, age, fitness level, and underlying health conditions. Strategies to improve exercise capacity may include regular physical activity, strength training, and aerobic exercise. By increasing exercise capacity, individuals can improve their overall health and quality of life.
