Physical activity is essential for maintaining both physical and mental health. However, it presents several challenges, especially during high-intensity efforts. Sprints, for instance, place significant demands on muscles, particularly Type II fibers, which are responsible for rapid and powerful contractions. These fibers, however, fatigue quickly due to lactic acid buildup and limited oxygen supply, leading to a decline in performance. Additionally, the efficiency of muscle contractions and optimal distribution of nutrients and oxygen to muscles are often limiting factors, even for well-trained athletes.
