How does increased flexibility contribute to injury prevention?

Increased flexibility significantly contributes to injury prevention primarily by allowing a greater range of motion. When muscles and connective tissues are more flexible, joints can move through their full range without restriction. This improved mobility lowers the likelihood of strains, sprains, and tears that often occur when muscles are tight and restricted.

For example, flexibility in the hip joints, hamstrings, and quadriceps can enhance athletic performance and reduce the risk of injury during activities that involve sudden acceleration or deceleration, twisting movements, or heavy lifting. Additionally, flexible muscles and tendons can better absorb the impact and force generated during these activities, further decreasing the risk of injury.

In contrast, other options do not directly address the role that flexibility plays in range of motion and injury prevention. Improving muscle size and enhancing metabolic rate relate more to strength and energy expenditure and do not inherently protect against injuries. Reducing stress levels, while beneficial for overall health, does not have a direct mechanical impact on joint and muscle flexibility. Thus, flexibility remains the most critical factor in facilitating a safe and effective range of motion to prevent injuries.
