Metabolic Adaptations to HIIT training Flashcards
1
Q
What is the common lab based experimental HIIT protocol?
A
Wingate test
2
Q
What does HIIT training cause an increase of?
A
- VO2 max
- proportion of lipid to carbohydrate used during exercise, at a given moderate intensity
- muscle mitochondrial content
- muscle glycogen content
- endurance and sprint performance
3
Q
What does HIIT training cause an decrease of?
A
- muscle glycogen breakdown
- lactate production
4
Q
How does HIT training compare with continuous training?
A
More time efficient and potent training stimulus
5
Q
What is HIIT?
A
Relatively intense but submaximal efforts that elicit >80% of HRmax.
6
Q
What is Sprint Interval Training (SIT)?
A
Efforts performed in an ‘all out’ manner or at an intensity >100% of VO2max.
7
Q
When it comes to mitochondrial content, what is more important, volume or intensity?
A
Volume - increased training volume causes a far greater spike in citrate synthase activity.
