Physics is very common in our lives, and of course this also applies to the performance of a runner.
For example, he or she needs to understand the air resistance when running, they may need to find a way to reduce the most air resistance that is against them so that they can show their best performance.
Or another example is they may need to find out the friction acting on between their feet and the track, they may need to adjust their training in different textures of running tracks, as each acts a different amount of friction.
Explanation:
Biologists attempt to answer questions about the living world.
Answer:
c. Vasodilation causes arterial diameter to increase in the exercising skeletal muscle
Explanation:
Cardiac output increases blood pressure due to increased pumping action of the heart. To protect the blood pressure to rise to the fatal levels during exercise or any other activity of excessive muscle contraction, blood vessels are stimulated to dilate.
Dilation of arteries dissipates some of the blood pressure. The arteries with larger diameter have less blood pressure than the arteries with a narrow cavity under the conditions of the same cardiac output. Therefore, the dilation of arteries Dilation does not allow the blood pressure to rise to the harmful levels.
