Question

Why is the sympathetic division of the autonomic nervous system active just before the race?

Answer 1

The sympathetic division of the autonomic nervous system is active just before the race because it functions to mobilize resources of the body for energy expenditure and as well metabolism, for the purposes of increasing physical activities inside the body such as blood pressure, heart rate, breathing rate, which are important aspects during exercises

Answer 2

Answer:

The sympathetic division of the nervous system is active under the fright and stressed conditions. In the stressed conditions the body becomes more alert and active.

Before race the body and mind is under stressful condition to give its best. Under the stress conditions the sympathetic nervous system controls the heart rate and other mechanism.

So, before race the sympathetic division of the autonomic nervous system becomes active.
