Q

What are fats(healthy)

A

provides 2/3 of energy requirements at rests. As intensity increases fat use decreases the use of CHO use. Used in your daily diet 25-30%. n example is avocadoes

Q

What is the glycaemic index?

A

The GI is a 2 hour period provides an indicator of how quickly glucose is broken down and released into the bloodstream. Its a scale from 0-100.

Q

Describe to advantages of the ATP-PC sytem

A

1.enables the athlete to work at maximal capacity-HRM 95%

Q

Describe 2 disadvantages of the ATP PC system

A

1.finite capacity as there is only 2-3seconds worth of PC stored in the muscles.
2. maximal capaity can maintained for 10 seconds

25
Explain why the ATP PC system has a finite capacity?
because PC stores deplete in 10 seconds
26
Why do you need to have a Passive recovery for ATP PC system
A passive recovery will enable PC to rebuild at the most rapid rate
27
Why so sprinters walk slowly between there sprints?
because they need a passive recovery to enable PC to be rebuilt at the fastest rate. This wil enable the sprinter to perform their next sprint at the maximal intensity(95%HRM) and maintain a high contribution from the ATp PC system
28
What is the fatiguing mechanism of ATP_PC
PC depletion
29
What is the capacity of ATP-PC
very low capacity to rebuild ATP
30
What is the Chemical pathway for the anaerobic gycolosis system and the re-synthesis of ATP
glycogen-glucose-pyruvic acid-lactate/H+ accumulation
31
Describe why the anaerobic glycolosis system cant produce energy (rebuild) as rapidly as the ATP system?
the anaerobic system can not rebuild atp as rapidly as it has a more complex chemical pathway this results in decreased intensity-85-95%
32
What is the food fuel for the ATP-PC system?
no food fuel!
33
What is the fuel substrate of the ATP-PC system?
Creatine Phosphate
34
What is the intensity of %Hrm of the ATP-PC system?
95+
35
What is the rate of ATP re synthesis of the ATP-PC system?
very rapid
36
What is the capacity of the ATP-PC system?
very low
37
What is the yield of the ATP-PC system?
one
38
What is the fatigue mechanism of the ATP-PC system?

39
Is the ATP-PC system finite or infinite?
Finite
40
What is the recovery type for of the ATP-PC system?
Passive
41
What is the advantage of the of the ATP-PC system?
work at maximal HRM
42
What is the disadvantage of the ATP-PC system?
only use for 10 seconds on ly stored in the muscles for 2-3 seconds
43
Example sports for the ATP-PC system?
Sprinter,netballer

What is the rate of ATP re synthesis for the Anaerobic Glycolosis system?
Rapid
47
What is the %hrm for the Anaerobic Glycolosis system?
85-95%
48
What is the capacity for the Anaerobic Glycolosis system?
low
49
What is the yield for the Anaerobic Glycolosis system?
2ATP
50
What is the fatigue mechanism for the Anaerobic Glycolosis system?
H+/Lactate accumulation
51
Is the Anaerobic Glycolosis system Finite or infinite?
Finite
52
What is the recovery type for the Anaerobic Glycolosis system?
Active
53
What is the advantage for the Anaerobic Glycolosis system?
Work for longer than the ATP-PC system without oxygen
54
What are the disadvantages for the Anaerobic Glycolosis system?
fatiguing bi-products
55
Example sports for the Anaerobic Glycolosis system?
middle distance(400m)
56
What is the food fuel for the Aerobic Energy System?
