Final answer:
Warming up before attending a maximal test is crucial to prevent injuries by gradually increasing the intensity of physical activity and preparing the muscles for the test.
Step-by-step explanation:
Warming up before attending a maximal test is crucial to prevent injuries. A warm-up is a gradual increase in the intensity of physical activity that prepares the muscles for the upcoming test. It increases blood flow to the muscles and raises the heart rate, making the muscles and tendons less prone to injuries. For example, before attending a maximal test, one can perform light jogging or stretching exercises to warm up the muscles and increase heart rate.
