Answer:
the answer is c
Explanation:
Doing a warmup before exercise is important because it B. increases blood flow throughout the body.
During a warmup, the body undergoes physiological changes that prepare it for the upcoming physical activity. One of these changes is an increase in blood flow. When you engage in a warmup, your heart rate gradually increases, leading to the dilation of blood vessels. This dilation allows for increased blood flow to the muscles and other tissues involved in exercise.
Increased blood flow is beneficial for several reasons. First, it delivers oxygen and nutrients to the muscles, providing them with the necessary fuel for optimal performance. It also helps remove waste products, such as carbon dioxide and lactic acid, which can accumulate during exercise and contribute to muscle fatigue.
Furthermore, increased blood flow aids in warming up the muscles, ligaments, and tendons, making them more pliable and less prone to injury. This enhanced flexibility allows for improved range of motion and better overall performance during exercise.
On the other hand, not warming up adequately before exercise can increase the risk of injury. Without a proper warmup, the muscles may be tight and less prepared for the demands of physical activity, making them more susceptible to strains, pulls, or other types of injuries.
In summary, a warmup before exercise is essential because it increases blood flow throughout the body. This helps deliver oxygen and nutrients to the muscles, removes waste products, warms up the tissues, and reduces the risk of injury.
