Question 1

What is aerobic exercise and its long term effects?

Answer 1

Working at a moderate intensity level with oxygen. Training this will increase the ability to work for long periods of time, this could apply to long distance running for example or the ability to run for 90mins during a football game.

Question 2

What is anaerobic exercise and its long term affects?

Answer 2

Working at a high intensity level without oxygen. The effects of training will increase the ability to move in quick bursts, this could apply to sprinting for the ball in football or improved time in sprint distances.

Question 3

What are the long term effects of exercise on the musculo-skeletal system?

Answer 3

• An individuals muscles are often toned and look strong
• Increased bone density (preventing osteoperosis)
• Muscle hypertrophy
• The body adapting to training loads imposed on it
• Increased strength of ligaments and tendons

Question 4

What are the long term effects of exercise on your heart in the cardiovascular system?

Answer 4

• Decreased resting heart rate supplying the same amount of blood with fewer beats
• Faster recovery rate the fitter you are
• Stroke volume at rest and work increases
• Maximum cardiac output increases
• Size, strength and thickness of the heart increases

Question 5

What are the long term effects of exercise on your blood in the cardiovascular system?

Answer 5

• The number of capillaries in your heart increases making vessels more efficient
• Increased number of red blood cells
• Drop in resting blood pressure due to the muscular wall in vessles becoming more flasible and elastic

Question 6

What are the long term effects of exercise on the respiratory system?

Answer 6

• Increased lung efficiency and capacity/volume and vital capacity becoming better at delivering oxygen to your working muscles
• Increased number of alveoli will be available for gaseous exchange so more oxygen can be absorbed
• Increased strength of the diaphragm and external intercostal muscles increasing airflow in ohysical activity

Question 7

What is cardiac output, stroke volume and recovery rate?

Answer 7

Cardiac output - the amount of blood ejected from your heart in one minute (Cardiac Output) = (Stroke Volume) x (Hearth Rate)
Stroke volume - the amount of blood pumped per beat.
Recovery rate - the speed at which your heart returns To resting heart rate after you exercise.
