Fatigue & Recovery
Energy systems and the most likely cause of fatigue
ATP-PC
-
Fuel Depletion- PC,ATP,ADP
-
Accumulation of metabolic by-products- Pi(inorganic phosphates), ADP
​​
Anaerobic Glycolysis
-
Accumulation of metabolic by-products-H+ ions, Pi
-
Reduced neuromuscular events- Decreased CNS firing
​​
Aerobic
-
Fuel Depletion- Glycogen stores then fats
-
Elevated body temperature- dehydration, blood flow away from muscles
Energy systems recovery
ATP-PC
Passive -rest recovery
​
Anaerobic Glycolysis
Active recovery 75 % using same muscle groups, massage, contrast hot cold baths
​
Aerobic
Dietary- High Gi immediately, rehydration
Non -Dietary- Massage, Hydro/water based therapies, active recovery
Can you
-
Define LIP
-
Identify LIP on a graph
-
Understand why lactate accumulates beyond LIP
-
describe the impact of exercise intensities beyond LIP on fatigue
-
identify the differences in LIP between a trained and untrained athlete
-
describe how training can improve LIP
