The ability of the muscular system to exert a force for a short period of time. The amount of force exerted depends on the size, number and co-ordination of the muscles involved.

This is important in everyday life to carry objects.

With a healthy, balanced lifestyle, your strength is improved by:

- Enlarges slow-twitch fibres givign a greater potential for energy production

- The size and number of mitochondria is increased.

- Causes musles to get bigger and stronger (hypertrophy)

Muscular Endurance

This is the ablility of the muscle or group or=f muscles to repeatedly contract and keep going without rest.

With a healthy, balanced lifestyle, your muscles can keep on going for longer due to greater areobic potential.

Activities like swimming can enlarge slow-twitch fibres improving energy production.

The number of mitrochondria are also imcreased as weel as an increase of myoglogin in the muscle cell.

Anareobic - Increase the sizer of fast-twitch muslces (hypertrophy).

The heart muscle becomes healthier and the size can increase (cardiac hypertrophy).

Cardiovascular Endurance or Stamina

The cardiovascular system involves transporting oxygen around the body. This includes:

- Heart

- Blood Vessels

- Blood

The benefits of a healthy, balanced lifestyle for your cardiovascular system include:

- healthy capillaries and increase in capillary density and efficiency

- healthy heart (less likely to suffer from heart disease).

- Good blood circulation; alongside exercise that can increase the amount of blood pumped by the heart

- Healthy blood pressure and a decrease in resting heart pressure

- feeling energetic - increase in haemoglobin which carries oxygen.
