The Anaerobic Energy Systems 7
muscle influences ability to generate all-out
energy for brief durations
· Longer duration performance,
carbohydrates, fat, and protein provide
necessary energy to recharge the pool of
high energy phosphates
· PCr reformation takes place only during
recovery
Task
· Read through research article to answer
the following:
· What are the effects of different recovery
duration of the levels of high energy
phosphates?
High-intensity Exercise Research
· Bogdanis et al. (1995) 30 s sprint
PCr = 19.7 and ATP = 70.5% of the resting values,
muscle lactate was 11.9 mmol and muscle pH was
6.72.
· 1.5 minutes of recovery, PCr increased to 65% of
resting levels, but reached only 85% with 6 min
recovery.
· No change in ATP or glycogen after 6 min
· After 6 min of recovery peak W, speed and mean
power were all lower than the original sprint
