What is the purpose of the preliminary warm-up phase?

The preliminary warm-up phase serves a crucial role in preparing the body for intense exercise. During this phase, individuals typically engage in light aerobic activities and dynamic stretching which gradually increases the heart rate, enhances blood flow to the muscles, and boosts overall body temperature. This physiological preparation helps to improve muscle elasticity and joint range of motion, thereby reducing the risk of injury during more vigorous activities. Additionally, a thorough warm-up can enhance performance by increasing the efficiency of muscular contractions and oxygen delivery. The warm-up phase sets a positive tone for the workout, ensuring that the body is adequately prepared for the demands it will face.
