Calcium plays a vital role in several bodily functions, particularly for athletes, where it supports muscle contraction, nerve function, and bone health. Adequate calcium intake is essential to prevent injuries like fractures and to support recovery during intense physical activity. It also aids in maintaining bone density, which is crucial for athletes who experience frequent stress on their bones from high-impact activities. Beyond bone health, calcium helps regulate heart rhythm and metabolic functions, highlighting the importance of including calcium-rich foods in an athlete's diet to support their physical demands.
