general term used to describe the ability to perform physical work
Maximum Oxygen consumption
Maximum amount of energy consumed during maximal effort
ability to work for prolonged periods of time
conditioning (aeorobic exercise training)
a change of energy utilization of the muscle by means of an exercise regimen
changes in the cardiovascular and muscular system to increase effeciency
Myocardial Oxygen Consumption (mVO2)
amount of oxygen consumed by the myocardial muscle
decreased maximum O2 consumption, cardiac output, and muscle strength due to immobility
anaerobic system that takes place within the first 30 seconds of exercise
Anaerobi Glycolytic System
ATP is synthesized within 30-60 seconds of exercise
- Oxygen required
- predominates over other energy systems
3 types of muscle
- Slow twitch (type I): more endurance
- Fast Twitch (Type IIb): power
- Fast Twitch (Type IIa): properties of both
What type of activity enhances anaerobic power?
1-2 minutes repeated after 4-5 minute break
What type of activity enhances aerobic power & endurance?
maximum intensity 3-5 minutes; repeat
What type of activity enhances endurance?
submaximal activity for 20-30 minutes
What is a kilocalorie?
The amount of heat necessary to raise 1kg of water 1 degree celsius
what is MET
- oxygen consumed per kg of body weight per minute
- 1 MET = 3.5 ml/kg per minute
- Light work 1.6-3.9MET
- Heavy Work 6.0-7.9MET
equation for efficiency
work output = force * distance
Work input equals....
energy expenditure expressed as net oxygen consumption per unit of time!
