long terms effects of physical activity Flashcards
1
Q
what long term effects of physical activity
A
- adaptations of the cardiorespiratory system
- adaptations of the musculoskeletal system
2
Q
what adaptations of the cardiorespiratory system are caused by exercise
A
- increased blood volume and haemoglobin
- increased oxygen extraction
- blood pressure approximates
- efficient respiratory rate
- a faster rate of recovery
3
Q
what is increased blood volume and haemoglobin
A
- Increase in plasma volume and red blood cell count stimulated by exercise.
- More oxygen can be transported from the lungs to working muscles
- carbon dioxide can be removed.
4
Q
what is increased oxygen extraction
A
- More oxygen is extracted from the circulatory blood
- due to increased cardiac output
- enhanced capacity of the muscles to extract oxygen due number of capillaries surrounding muscle fibres to facilitate gas exchange
5
Q
what is blood pressure approximated
A
- Training decreases systolic and diastolic pressures
- Means that the heart does not have to work as hard to pump blood around the body
