1 Energy Systems Adaptations to Training Energy systems: increased aerobic and anaerobic enzymes; increased use of fats as an energy source

2 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 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 Energy System Adaptations to Anaerobic Training

3 -↑ the availability of carbohydrate and fats as substrate to meet cellular needs for ATP resynthesis. -↑ capillary density -↑ myoglobin content (increases extract of O 2 to the muscle cells) -↑ activity of oxidative enzymes (aerobic pathways) -↑ oxidative capacity linked to ↑ numbers of mitochondria -Therefore O 2 ↑ utilization -↑ the availability of carbohydrate and fats as substrate to meet cellular needs for ATP resynthesis. -↑ capillary density -↑ myoglobin content (increases extract of O 2 to the muscle cells) -↑ activity of oxidative enzymes (aerobic pathways) -↑ oxidative capacity linked to ↑ numbers of mitochondria -Therefore O 2 ↑ utilization Adaptation to Aerobic Training

4 Increased capacity to oxidize Fats Increased capacity to oxidize Fats shifts the energy source from glucose to fat (to spare glucose) Decreased utilisation of the anaerobic glycolysis (LA) system ↓ lactate concentration ↑ clearance of lactate during exercise Adaptation to Aerobic Training
