What is the definition of maximal stimulus?
The maximal stimulus is the strongest stimulus that produces increased muscle contractile force.
How does exercise affect the inspiratory area?
If blood flows through the lungs twice as fast as rest, it picks up twice as much oxygen per minute because as cardiac output rises, the rate of blood flow through the lungs also increases. Furthermore, the rate at which O2 diffuses from alveolar air into the blood increases during maximal exercise because blood flows through a larger percentage of the pulmonary capillaries, providing a greater surface area for diffusion of O2 into the blood. Also, when exercise is strenuous and demanding the breathing rate will increase. At the end of an exercise session, an abrupt decrease in ventilation rate is followed by a more gradual decline to the resting level.
A period of rest between exercise training sessions is critical for maximal improvement in physical fitness This is often referred to as?
the principle of recuperation.
How does increasing the duration of the rest period affected muscle tension?
Increasing the duration of the rest period increased the duration of the subsequent maximal tension.
What is maximal speed?
Maximal strength is when your stamina improves in your muscle's.
What does the medical abbreviation PMI mean?
Point Of Maximal ImpulsePoint of Maximum impulse or Point of Maximum Intensitypoint of maximal intensitypoint of maximal impulse
How and why does aging affect the maximal heart rate?
Young children generally have a maximal heart rate approaching 220 beats per minute. This maximal rate falls throughout life. By age 60 maximal heart rate in a group of 100 men will average about 160 beats per minute. This fall in heart rate seems to be a linear process so that maximal heart rate can be estimated by the formula 220- AGE. This is an ESTIMATE, however. If we actually measure the maximal heart rates of those same 100 men during a maximal exercise test we would probably see a range of heart rates between 140 and 180. There is no strong evidence to suggest that training influences the decline in maximal heart rate. This reduction appears to be due to alterations in the cardiac electrical conduction system (SA node and Bundle of His), as well as down regulation of beta-1 receptors, which decreases the heart's sensitivity to catecholamine stimulation.
Why is there a maximal voltage for muscles?
All of the muscles in the muscle fiber have contracted when there is a maximal voltage and there is a maximal voltage to prevent injury to our muscles. Dr. Sayed

Why and how does blood pressure change during steady state exercise?
Stroke volume: Stroke volume is the amount of blood ejected per beat from left ventricle and measured in ml/beat. Stroke volume to its highest during sub maximal exercise and doesn't increase during maximal exercise. The greatest increase of stroke volume increases in the transition from rest to moderate exercise, during maximal exercise stroke volume doesn't go over its peak of 120 - 140 per minute Starling's law states that the stroke volume is limited towards the venous return, of which is the amount of the blood that is available to enter the left atrium and pass to the left ventricle
