Atp-pc System

Question 1

ATP-pc breakdown

Answer 1

Atp goes to ADP +P + energy
Pc goes to P+C + energy
Energy + P+ ADP goes to ATP

Question 2

How long does it last?

Answer 2

8-10 seconds

Question 3

Good for?

Answer 3

Short duration, high intensity events.

Question 4

What is Lactate

Answer 4

Lactic acid dissociates into lactate and h+ ions in the blood.

Question 5

Lactate/ anaerobic threshold

Answer 5

The workload at which the first increase in lactate above resting values is observed.

Question 6

OBLA

Answer 6

onset blood lactate accumulation.
The rate of blood lactate removal.

Question 7

OBLA/ Lactate sampling?

Answer 7

OBLA is the point where lactate starts to reduce your performance.

Question 8

5 factors effect the rate of Lactate accumulation.

Answer 8

Excersise intensity
Muscle fibre tyre
Respiratory exchange ratio
Fitness if performer
Vo2 max

Question 9

How does excersise intensity affect the rate of lactate accumulation?

Answer 9

OBLA occurs faster with high intensity activity’s because of the lactic acid production.

Question 10

Muscles fibre effect on lactate accumulation

Answer 10

Slow twitch fibres produce less lactate due to presence of oxygen

Question 11

Respiratory exchange ratio

Answer 11

The closer RER gets to 1 the more likely glycogen is being used anatomically - greater chance of accumulation.

Question 12

Fitness of performer

Answer 12

Regular training creates adaptations which improve capacity for anaerobic respiration

Question 13

Vo2 max

Answer 13

The higher Vo2 max the greater the delay in lactate accumulation.
