The Physiology Of Training: Effects Of Aerobic And Anaerobic Traininh

Question 1

What is overload

Answer 1

Training effects occurs when a physiological system is exercised at a level beyond what its normally used to

Question 2

Specificity. Training effect is specific to:

Answer 2

1.muscle fibres recruited during exercise
2.energy system involved
3.velocity of contraction
4.type of contraction

Question 3

Training to increase vo2 max

Answer 3

1.large muscle groups, dynamic activity
2.20 to 60 min >3 times per week > 50% vo2 max

Question 4

What is an average increase in vo2 max

Answer 4

15-20% however there are low and high responders

Question 5

What percentage of training adaptations is hereditary

Answer 5

47% approx

Question 6

Why are there differences in vo2 max

Answer 6

Primarily due to differences in sv max.

Question 7

Training induced increases in arteriovenous o2 difference

Answer 7

1. Muscle blood flow increases
   Descrease in sns vasoconstriction
   Increase diameter and compliance of arteries

Question 8

Another way training induced increases in arteriovenous o2 difference

Answer 8

2.improved ability of muscle fibres to extract and utilize o2 from the blood
Increased capillary density
Increased mitochondrial number/volume
