Energy systems and effects of exercise Flashcards
The energy system used depends on what 2 factors?
Intensity and duration
What dose ATP stand for?
Adenosine Triphosphate
How long dose the Phospho Creatine system last?
10 seconds
In the presents of oxygen, what energy system is being used?
Aerobic
ATP is re-synthesised by ADP, what dose ADP stand for?
Adenosine Disophate
What are the 3 short term (immediate) effects of exercise on the muscles?
Increased demand for oxygen
Increased size
Faster contraction
Larger recruitment of muscle fibres
Heat is a natural form of energy name 2 more?
Radiation Mechanical Nuclear Chemical Electrical
What are the 2 long term effects of exercise on the muscles?
Improved muscle tone and bulk
Increase in strength and endurance
Development of physique
More efficient gaseous exchange
What are 3 short term effects of exercise on the lungs?
Increased: rate and depth of respiration
Increase in gaseous exchange
Activate larger area of the lungs
More efficient gaseous exchange at the lungs
2 long term effects on the lungs
Muscles involved in respiration become stronger
Breathing feels easiergreater surface area of the lung used
Gaseous exchange in the alveoli becomes more efficient
3 long term effects on heart
Stronger heart muscle
Increased efficiency
Lower blood pressure
Lover heart rate
2 long term effects on blood vessels?
Keeps larger arteries flexible Improved circulation Blood vessels become more conditioned Blood pressure reduced More capillaries grow More red blood vessels grow
Where is ATP stored?
Myosin heads
What are the 2 effects of exercise?
Immediate
Long term
ATP is resynthesised by which energy system?
Lactic Acid System
