For the first assignment of the class, we focused on the elements of a physical education lesson plan, the first portion of the lesson being the warmup. The main aspects of the warm-up that we learned about were the importance of them in elementary physical education. The main point of warming up before performing physical exercise is to increase the muscle and body temperature, by doing this and allowing your muscles to get warmer oxygen becomes more available to your muscles, allowing them to contract and relax more easily. Another important part of warming up is that it helps reduce the chance of injury by helping improve muscle elasticity. Warm-ups are high-intensity activities that will introduce or be related to the body of the lesson in some way.
