Adaptations to Sprint Exercise Flashcards
What variables can be adjusted in interval exercise to impact the adaptations to training?
Work duration Rest duration Work:Rest Ratio Intensity Mode Weekly Frequency Number of Repetitions
What is high intensity interval training?
> 85% VO2max or HRmax during work intervals
Which metabolic pathways provide the majority of energy for ATP resynthesis during repeated sprints?
Phosphocreatine and Oxidative Metabolism
What paper shows the increase in oxidative energy contribution to repeated sprints?
Parolin et al 1999
What impact does HIIT vs MICT exercise have on the activity of citrate synthase accoridng to MacInnes et al 2017?
HIIT had higher citrate synthase activity
What did Karstoft et al 2015 say about HIIT?
Interval Walking in type 2 diabetics had a much higher maximal aerobic capacity, decreased fat mass and decreased blood sugar vs Continuous walking
A 1 MET (equivalent to BMR) increase in VO2max would reduce the risk of all-cause mortality by:
19%
Compare endothelial function between HIIT and MICT
Higher endothelial function in HIIT, so less likely to suffer heart failure, and less likely for it to be fatal
With did Gibala 2015 say about the physiological adaptations of supramaximal interval training compared to those of traditional aerobic exercise?
Produces similar physiological adaptations despite dramatically lower exercise volume and time commitment
According to Burgomaster et al 2005, what effect does sprint interval training have on time to exhaustion?
Significantly improves it (about doubles it in two weeks)
According to Burgomaster et al 2006, how does sprint interval training compare to endurance training on improving time trial performance?
Similar improvements in time trial performance but with 10% of the work/energy expenditure over 2 weeks.
According to Gibala et al 2006, what effect does sprint interval training having on Carbohydrate Stores comapared to endurance training?
Similar significant increase
According to Shepard et al 2012 what effect does Sprint interval training have on Intramuscular triglyceride stores compared to endurance training?
Significant increase in both type I and type II fibres, similar to endurance training
According to Gibala et al 2006, what effect does sprint interval training have on buffering capacity compared to endurance training?
Significant increase, similar to endurance training
According to Metcalfe et al 2012 and Metcalfe et al 2016 what effect did a 10 minute sprint interval training protocol have on VO2max?
10-14% mean increase in VO2max
