The body adapts to regular physical training through various physiological changes. These adaptations include increased muscle strength, improved cardiovascular efficiency, and enhanced endurance. As training intensity or duration increases, the body responds by strengthening muscle fibers, increasing the number of mitochondria, and improving oxygen uptake and utilization. Over time, these adaptations not only enhance performance but also contribute to overall health by reducing the risk of chronic diseases, improving metabolic function, and promoting a better quality of life.
