Energy continuum and contribution Flashcards
What is the energy continuum
The relative contribution of each energy system to physical activity
What energy system is the highest contributor to very high intensity
95% ATP/ATP-PC - less than 10 secs
What energy system is the highest contributor to high intensity
60-90% glycolytic - 10 secs to 3 mins
What energy system is the highest contributor to moderate - low intensity
95% aerobic - more than 3 mins
What energy system will be used if O2 is available
Aerobic
What is the point where a performer’s dominant energy system switches
Threshold
What are 4 factors affecting contribution of energy systems
Position, tactics, level of comp, nature of sport
At what point of lactate levels does OBLA set in
4 mmol/L
What is the lactate training zone
80-90% of MHR
How does training reduce fatigue
Body buffers lactic acid and negative effects of glycolytic system delayed
What are 5 ways to delay OBLA
More myoglobin, more efficient CV system, increased O2 uptake at muscles, increased PC stores and glycogen stores
