Metabolic Adaptions To HIIT Flashcards
What is HIIT
High intensity interval training w a potent time efficient strat to induce numerous metabolic adaptations similar to endurance training
Study: HIIT exercise endurance capacity
Participants cycled 80% of v02 max until fatigue and HIIT improved exercise duration from 26 to 51 min over 2 weeks
Comparison between HIIT and endurance training:
Both hiit and endurance training improves exercise capacity
Study: HIIT training increase muscle glycogen in resting condition and decreased glycogen breakdown during exercise
Hiit training decreases lactate production while increasing pdh activity during exercise
Summary of adaptions to HIIT
1.Increases vo2 max and proportion of lipid to carb used during exercise at a given absolute moderate intensity
2.increased muscle mitochondrial and glucose content
3.increased endurance and sprint performance
4.decreased muscle glycogen breakdown
5. Decreased lactate production
What happens when there is an interruption of endurance training
1.decrease muscle mitochondrial content
2. Decrease muscle lipoprotein lipase
3. Increase adipose tissue lipoprotein lipase
4.decrease in resting muscle glycogen
