Recovery Process (A2) Flashcards
What does EPOC stand for and what does it mean?
Excess Post Oxygen Consumption
Volume of oxygen consumed after exercise to return the body to its pre-exercise state
What state is the body in post-exercise?
Myoglobin O2 levels -> Low saturation % ATP levels -> Low PC levels -> Low Glycogen stores -> Low Lactic acid -> High Temperature -> High
What are the two components of EPOC (with%)?
Fast alactacid (10%) Slow lactacid (90%)
What does EPOC depend on?
Exercise intensity and duration
What are the 2 main parts of the alactacid recovery (fast)?
Replenish blood and muscle oxygen
Resynthesise PC stores
What takes place during replenishment of blood and muscle oxygen (fast)? (during exercise and recovery)
During exercise -> Oxygen dissociates from haemoglobin in bloodstream and myoglobin at the muscle
During recovery -> Oxygen resaturates bloodstream then muscles
What takes place during resysnthesis of ATP stores (fast)? (during recovery)
30 seconds for 50% ATP recovery
3 mins for 100% ATP recovery
Phosphates are used to restore high energy bonds (ADP)
What are the 3 main parts of the lactacid recovery (slow)?
Removal of waste (lactic acid)
Elevated body temperature
Elevated ventilation and circulation
What takes place during removal of lactic acid (slow)?
Either oxidised or converted to glycogen:
50-75% of lactic acid is converted back to Pyruvic Acid (Krebs Cycle)
10-25% converted back to glucose
Can be removed during sweating/urination
How long does the removal of lactic acid take (slow)?
Lactate removal takes around 1 hour
Can take up to 24 hours
What takes place during body temperature phase (slow recovery)?
Temperature remains high as 1 degree increase can increase metabolic rate by 15%
Accounts for majority of O2 in recovery
What takes place during ventilation and circulation phase (slow recovery)?
HR remains high (as do circulation and ventilation
Gradual decrease to allow for delivery of O2 and removal of waste products
What 7 things does recovery depend on?
Warm up Active recovery (cool down) Cooling aids Intensity of training Work:rest ratio Strategies/ tactics (time outs) Nutrition
Effects of warm up, active recovery and cooling aids on recovery:
Warm up: Minimise time using anaerobic system
Active Recovery: Maintain HR, speed up lactic acid removal
Cooling Aids: Post event to speed up lactic acid removal and reduce muscle soreness & DOMS
Effects of intensity of training on recovery:
High intensity: Increase fast component efficiency (more ATP, PC storage) Increase lactic acid tolerance Delay OBLA Low intensity: Increases aerobic capacity Maximise O2 delivery during EPOC
