The Immediate Effects of Exercise

Topic Respiratory System.

As soon as you begin to exercise your muscle cells increase their demands for oxygen (O 2 ). As exercise continues there is also an increased need to remove.

Changes to the Circulatory System Stronger heart muscle Increased stroke volume Increased cardiac output Lower resting heart rate Increased capilliarisation.

CHANGES TO THE BODY DURING EXERCISE. Short term changes to the body When you exercise changes happen to the body to help it cope with the extra demands.

The Body Structure and Function

Oxygen Transport System The main aim of the Oxygen transport system is to help a person exercise. The oxygen transport system provides the muscles and the body with oxygenated blood that helps the body to keep working efficiently. The harder you train, the harder your oxygen transport system must work. However, as a person becomes fitter, less effort is needed for the same amount of work.

Oxygen Transport System Cont. The Oxygen transport system is made up of the respiratory system and the circulatory system. Give a definition of each of these systems. Which activities from your Standard Grade course will make the most demands on your oxygen transport system?

Why Exercise? Regular exercise increases the size of the heart allowing more blood to be pushed around the body with every beat of the heart. -Will this lower or raise your heart beat? - Now check your resting heart beat. My resting heart beat is_______bpm.

Why Exercise Cont. Regular exercise increases the Vital Capacity of the lungs. This means that your lungs can take in more oxygen with each breath you take. - Now check your resting breathing rate. - My resting breathing rate is_____ times per minute.

Oxygen Debt If the body is performing at a high intensity for long periods of time, it can become difficult for your breathing to supply enough oxygen to working muscles. This will cause a build up of lactic acid in the muscles, and the body will slow down. This is known as Oxygen Debt. Can you think of FOUR activities where Oxygen Debt may be a problem?
