Energy Systems Adaptations to Training Energy systems: increased aerobic and anaerobic enzymes; increased use of fats as an energy source
Energy System Adaptations to Anaerobic Training • ATP – CP • Will increase stores of ATP & CP • Anaerobic Glycolysis (Lactic Acid System) • in levels of glycolytic enzymes • Less Lactic Acid produced, more efficient Cori cycle (converting lactic acid in the liver back to glucose to use) • Increased buffering capacity (acid-base balance) more able to tolerate lactic acid for longer! • More energy can be produced through these systems
Adaptation to Aerobic Training • ↑the availability of carbohydrate and fats as substrate to meet cellular needs for ATP resynthesis. • ↑ capillary density • ↑ myoglobin content (increases extract of O2 to the muscle cells) • ↑ activity of oxidative enzymes (aerobic pathways) • ↑oxidative capacity linked to ↑ numbers of mitochondria • Therefore O2 ↑ utilization
Adaptation to Aerobic Training Increased capacity to oxidize Fatsshifts the energy source from glucose to fat (to spare glucose) Decreased utilisation of the anaerobic glycolysis (LA) system ↓ lactateconcentration ↑ clearance of lactate during exercise
