A general term for various equipment, apparatus, and supplies used in competitive sports, athletic competitions, and fitness exercises. Sports equipment and sports activities are interdependent and mutually promote each other. The popularity of sports and the diversification of sports events have led to the development of types and specifications of sports equipment. Similarly, high-quality, stable-performance, and reliable sports equipment not only ensures fair and intense competitions but also creates the necessary material conditions to promote the improvement of sports skills. The human body is an organic whole composed of various organ systems. During sports activities, it may seem that only the muscles are in motion. In fact, the body's respiration, blood circulation, and other organs are also participating and are all coordinated by the cerebral cortex. Warming up is to enhance the excitement of the cerebral cortex neurons, and it also slightly raises body temperature, keeping muscles and tendons in good condition with good elasticity and extensibility, preventing injuries or tears due to sudden contractions, which is particularly important in winter. When throwing objects such as hand grenades, shot put, medicine ball, and baseball, it is crucial to follow the teacher's commands strictly, with no room for carelessness.
