Lactate Accumilation

Question 1

OBLA

Answer 1

(onset blood lactate accumulation)
- body can’t produce enough oxygen to break down lactic acid.
Untrained - 50% of VO2 max
Trained - 85% of VO2 max

Question 2

4 factors that affect the rate of lactate accumulation

Answer 2

1. Exercise intensity
2. Muscle fibre type
3. rate of blood lactate removal
4. Fitness

Question 3

Muscle fibre WORK:REST ratios

Answer 3

1. ATP-PC: Work 1 minute : Rest 3 minutes
   - Improves speed and power
2. Glycolytic: Work 1 minute : Rest 2 minutes
   - improves tolerance to lactic acid
3. Aerobic: Work 1 : Rest 1-0.5 seconds
   - improves VO2 max.
