Why?•Result: increase PC stores and increase enzyme activity (i.e. speed of ATP-PC system)Anaerobic Training•Improving Glycolysis•short high-intensity intervals; 20-60 sec•strength training•Result: 1. increase glycolysis enzyme activity 2. increase buffering of lactic acidAerobic TrainingAerobic Training1. Long, slow distance training2. High intensity, continuous trainingAerobic Training•LONG, SLOW DISTANCE TRAINING•Lower intensity level (~70% HRmax)•Outcome1. Increase capillaries2. Increase myoglobin3. Increase mitochondriaIncrease uptake of FFA and O2Long Slow Distance Training•What affect does aerobic training have on fat utilization? •Why?•What affect does aerobic training have on fat utilization? •Why?1. Increase capillaries2. Increase myoglobin3. Increase mitochondriaLong Slow Distance TrainingWhat affect does aerobic training have on glycogen levels inside the liver and muscles?What affect does aerobic training have on glycogen utilization? Why is this significant?Aerobic Training•HIGH-INTENSITY, CONTINUOUS TRAINING (~85% HRmax)•Increase lactate threshold•Why?1. Increase lactate removal2. Decrease lactate productionHigh Intensity, Continuous TrainingWhy is there a decrease in lactic acid production? Mitocho ndria(Krebs cycle & Electron Transport
