Adaptations to Anaerobic Training

Question 1

What is the gold standard for anaerobic fitness testing?

Answer 1

Wingate test

Question 2

Do anaerobic power & capacity increase or decrease with training?

Answer 2

Increase

Question 3

What are the muscle fibre adaptations to anaerobic exercise?

Answer 3

Increase in type IIa, IIx cross-sectional area
– Increase in type I cross-sectional area (lesser extent)
– Decreased percent of type I fibers, increased percent of type II

Question 4

What are the adaptations of the ATP-PCr system to anaerobic training?

Answer 4

Little enzymatic change with training

– ATP-PCr system-specific training - strength increases

Question 5

What are the adaptations of the glycolytic system to anaerobic training?

Answer 5

Increase In key glycolytic enzyme activity with training
(phosphorylase, PFK, LDH, hexokinase)
– However, performance gains from increase in strength

Question 6

What are anaerobic adaptations associated with high-intensity interval training (HIIT)?

Answer 6

High-intensity interval training (HIIT): time efficient way to induce many adaptations
normally associated with endurance
training
• Mitochondrial enzyme cytochrome oxidase
(COX) same after HIT versus traditional
moderate-intensity endurance training

Question 7

Why is an athlete’s VO2max higher in specific training rather than cross-training?

Answer 7

V•O2max substantially higher in athlete’s sportspecific activity
– Likely due to individual muscle group adaptations

Question 8

What is cross-training?

Answer 8

Training different fitness components at once or
training for more than one sport at once
– Strength benefits blunted by endurance training
– Endurance benefits not blunted by strength training
