Identify one risk factor for developing a sports injury.

Inadequate warm-up or flexibility training is a significant risk factor for developing a sports injury because it can lead to reduced muscle elasticity and joint range of motion. A proper warm-up is crucial as it prepares the body for physical activity by increasing blood flow to muscles, elevating body temperature, and enhancing neuromuscular control. Without it, muscles and connective tissues may not be sufficiently prepared for the stresses of exercise, increasing the likelihood of strains, sprains, and other injuries. Flexibility training is essential for maintaining joint health and preventing injuries; insufficient flexibility can lead to muscle imbalances and decreased overall performance. Thus, failing to engage in adequate warm-up and flexibility exercises can create an environment conducive to injury during athletic activities.
