Anaerobic Training

• Improving ATP-PC system

• short high-intensity intervals

• power exercises

• rest interval; 3-4x longer than interval. 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 acid

Aerobic Training

Aerobic Training

1. Long, slow distance training

2. High intensity, continuous training

Aerobic Training

• LONG, SLOW DISTANCE TRAINING

• Lower intensity level (~70% HRmax)

• Outcome

1.Increase capillaries

2. Increase myoglobin

3. Increase mitochondria

Increase uptake of FFA and O2

Long 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 capillaries

2. Increase myoglobin

3. Increase mitochondria

Long Slow Distance Training

What 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 removal

2. Decrease lactate production

High Intensity, Continuous Training

Why is there a decrease in lactic acid production?
