Which metabolic pathways are used in endurance exercise?
Phosphocreatine Breakdown, Anaerobic Glycolysis, & Carbohydrate/Fat Oxidation
1 of 9
Which metabolic pathway can produce ATP Fastest?
Phosphocreatine breakdown
2 of 9
What is the limitation of the fastest pathway?
ATP storage capabilities- ATP resythesis reaches maximum yield after 10 seconds of intense exercise
3 of 9
Where is most of the body's carbohydrate stored?
In the muscle
4 of 9
Which Fuel contributes to energy demands in high intensity exercise?
Muscle Glycogen (carbohydrate)
5 of 9
Which fuel contributes most to the energy demands in long duration exercise?
Fat
6 of 9
Which fuel contributes to energy demands at rest?
Fat
7 of 9
Why does glucose utilization not reach a maximal rate until about 90 min into exercise?
Gylcogen stores are reduced at this point in exercise, meaning less breakdown of glcogen and causeing hexokinase (enzyme) inhibitance to be lifted allowing more glucose to be utilized
8 of 9
What causes fatty acid utilisation to be reduced during strenuous exercise?
because carbohydrates are the favoured fuel as they can be broken down more rapidly at intense exercise
