Energy systems Flashcards
ATP-Pc System
high intensity
2-10seconds
can take up to 3 minutes to recover
Creatine
During ATP-PC system creatine phosphate is broken down by creatine kinase to create energy very quickly
P) improves ability to work at a higher intensity for longer
P) improves strength, power and recovery
N) stomach cramps
N) water retention
Glycolytic system
high intensity exercise after ATP-PC system
1) PFK breaks down 1 glucose into Pyruvic acid
2) enough energy to make 2 ATP
3) lactic acid is a product
Aerobic energy system
low intensity
3minutes+
60-80%
stage 1) Glycolysis - 2 ATP
stage 2) Krebs cycle- (mitochondria) CO2 is removed creating 2 ATP
stage 3) Electron transfer chain- hydrogens are passed along with their electrons jumping on and off making energy 34 ATP
OBLA
measures anaerobic capacity
4 = OBLA point
Lactate threshold = Anaerobic threshold
