Which parameters are decreased during moderate exercise?

When the body starts to anticipate that the body is about to undergo exercise, the central command will increase sympathetic outflow to the blood vessels and the heart. This can make the heart rate increase and contract.

The other choices are meant for different purposes. It is important for people to do some exercising because it will surely improve their body overall. It will help increase their blood flow, increase their cardiac output, and at the same time have a healthier body that will allow them to live for a long time. Just take a few minutes to exercise every day and this will already make a lot of difference.

Total peripheral resistance (tpr)-in anticipation of exercise, the central command increases sympathetic outflow to the heart and blood vessels, causing an increase in heart rate and contractility. venous return is increased by muscular activity and contributes to an increase in cardiac output by the frank-starling mechanism. pulse pressure is increased because stroke volume is increased. although increased sympathetic outflow to the blood vessels might be expected to increase total peripheral resistance (tpr), it does not because there is an overriding vasodilation of the skeletal muscle arterioles as a result of the buildup of vasodilator metabolites (lactate, k+, adenosine). because this vasodilation improves the delivery of 0 2, more 02 can be extracted and used by the contracting muscle.
