PHYSIOLOGICAL ADAPTIONS LONG TERM

Question 1

what are the aerobic adaptions in the muscles

Answer 1

1. increased myoglobin stores, allowing more 02 to be stored within the muscles and trnasported to the mitrochrondria
2. increased size and density of motrochrondria means increased rate of energy production
3. increased capilarisation around muscles diffusion of 02 into muscles
4. more efficient use of aerobic sources of fuel

Question 2

What are the cardiac long term aerobic responses

Answer 2

1. cardiac hypertrophy, (thicker stronger walls of left ventricle)
2. increased stroke volume
3. bradycardia
4. increased RBC & haemoglobin
5. increased elastcity of arterial walls

Question 3

what are the respitory long term aerobic responses

Answer 3

• hypertrophy of respitory muscles
• increased lung volume
• increased capilarisaion of alveoli
• increased surface area of alveoli

Question 4

what are the long term anaerobic adaptions in muscles

Answer 4

• muscle hypertrophy
• changes in 2b fibres to type 2a
• increased ATP-PC, creatine phospate & glycogen stores
• improved recruitment of motor units
• increased bone density
• increased elasticity of muscle fibres
