What is the primary function of warm-up exercises before physical training?

The primary function of warm-up exercises before physical training is to prepare the body for exercise and reduce injury risk. Warm-up exercises gradually increase the heart rate and improve blood circulation to the muscles, which helps raise the body's core temperature. This physiological preparation enhances muscle elasticity and joint mobility, making it less likely for individuals to experience strains or sprains during more intense physical activity. Additionally, warming up can psychologically prepare an athlete for the workout, enhancing focus and performance.

While increasing heart rate, building muscle strength, and improving flexibility can occur during warm-ups, they are not the central purpose. Instead, the broader goal of preparing the body functions as the foundation for sustaining a safe and effective workout, making it vital for an optimal training experience.
