a waste product produced in the muscle tissues during strenuous exercise where he anaerobic energy system is in use

muscle tiredness when the body has a lack of energy

the speed at which the body returns back to normal after exercise

when you exercise, the blood is diverted from inactive areas to the muscles that are being used. This action is completed through vasodilation and vasoconstriction (aka the vascular shunt mechanism)

The short term responses to exercise and changes in the body

Physical education

This unit will explore the immediate responses our bodies make to cope with the effects of exercise as well as the longer term adaptations it makes in response to training that enable us to cope better with exercise and improve performance.

Anatomy and physiology: the short and long term effects of exercise

What happens to muscle temperature when we start to exercise?

Which of the following statements is **incorrect** as a response to a gentle jog?

Which one of the following types of exercise will result in the greatest production of lactic acid?

Increased blood is redistributed to working muscles due to the {{ }} shunt mechanism.

of arteries supplying the digestive system to reduce blood flow

of arteries supplying the working muscles to increase blood flow

Match up the following descriptions of what happens to the redistribution of blood when we exercise.

Gaseous exchange happens faster during exercise because there is a {{ }} difference in concentration of oxygen in the alveoli compared to the bloodstream.

Which of the following substances are produced more quickly in the body during strenuous exercise?

Match the following to the correct body system.

to load the muscles up with fresh oxygen supplies

to reduce oxygen consumption quickly after exercise

Which of the following is **incorrect** about why our heart rate and breathing rate remain elevated during recovery?

the number of times you heart beats per minute

the amount of blood pumped out of the left ventricle per contraction

the volume of blood pumped per minute by each ventricle of the heart

the amount of air entering the lungs during normal inhalation at rest

Match up the following key terms with the correct definition.

use of oxygen for the duration of the exercise, usually at moderate intensity

high intensity exercise which does not allow for the predominant usage of oxygen

Which of the following is the correct definition of aerobic respiration?

When we cross the anaerobic threshold due to high intensity exercise, {{ }} is produced in the muscles.
