Lecture 1 Absolute vs Relative Acute vs Chronic Exercise Models
Acute Exercise
- A person/animal performing a single boot(session) of some type of exercise
- e.g. bike for 60 minutes
Chronic Exercise/ Exercise Training
- Repeated boots of exercise over a given period of time
Exercise Training
- Short-term (several days to weeks in length) or long-term (weeks, to months, to
years in length)
Different Type of Exercise
- Aerobic Exercise (with oxygen)
• Use of oxygen to adequately meet energy demands during exercise via
aerobic metabolism
• E.g. swimming, jogging
- Anaerobic Exercise (without oxygen)
• Physical exercise intense enough to cause lactate to form
• Non-endurance sports to promote strength, speed and power
• Build muscle mass
• E.g. sprinting, lifting a heavy weight
- Resistance Exercise
• Isometric exercise: strength training in which the joint angle and muscle
length do not change during contraction
- Flexibility training
- Balance training
Common Experimental Exercise Models
- Incremental progressive exercise test
• Increase the resistance or intensity at given intervals of time until fatigue
(when the individual feels they can no longer continue – volitional fatigue)
• There are other criteria to stop the test
• Useful to determine an individual’s adaptation to a training program or
physical fitness level
• Cool-down is important
- Steady state exercise
• Activity that achieves a balance between the energy required by working
muscles and the rate of oxygen and delivery for aerobic ATP production
• Moderate intensity exercise
• The removal of lactic acid by oxidation keeps pace with its production
• A workrate is selected and the individual exercises for a predetermined
period of time or until they can no longer continue
• Not a test? Purpose?
Document Summary
Lecture 1 absolute vs relative acute vs chronic exercise models. A person/animal performing a single boot(session) of some type of exercise. Repeated boots of exercise over a given period of time. Short-term (several days to weeks in length) or long-term (weeks, to months, to years in length) Aerobic exercise (with oxygen: use of oxygen to adequately meet energy demands during exercise via aerobic metabolism, e. g. swimming, jogging. Anaerobic exercise (without oxygen: physical exercise intense enough to cause lactate to form, non-endurance sports to promote strength, speed and power, build muscle mass, e. g. sprinting, lifting a heavy weight. Isometric exercise: strength training in which the joint angle and muscle length do not change during contraction. Interval or intermittent exercise: several periods of predefined exercise (intensity of power output determined) is separated by predefined periods of rest (light exercise or full rest) Can be applied to anyone and is expressed in a standard unit of measure.
