Factors Related to Aerobic Endurance Performance
Maximal Aerobic Capacity
- The measurement of the maximum amount of oxygen a person can utilize during intense exercise
Lactate Threshold
Intensity of exercise at which a specific blood lactate concentration is observed or the point at which blood lactate concentration begins to rapidly increase above resting levels
Maximal Lactate Steady State
The exercise intensity at which maximal lactate production is equal to maximal lactate clearance within the body
Exercise Economy
A measure of the energy cost of activity at a given exercise velocity
Steps for Designing an Aerobic Endurance Program
Exercise Mode
Training Frequency
Recovery
Obtaining sufficient rest, becoming rehydrated, and restoring fuel sources are critical issues during recovery
Intensity
- Adaptations in the body are specific to the intensity of training
Methods for measuring aerobic intensity
Heart rate as a measure of intensity
Functional Capacity
- Heart rate reserve (HRR)
Heart Rate Reserve
The difference between an athlete’s max HR and his or her resting HR
Age-Predicted Maximal Heart Rate (APMHR)
Karvonen Method
Percentage of MHR Method
- Target HR (THR) = APMHR x exercise intensity
Rating of Perceived Exertion (RPE)
1 -- Nothing at al (lying down) 2 -- Extremely little 3 -- Very easy 4 -- Easy (could do this all day) 5 -- Moderate 6 -- Somewhat hard (starting to feel it) 7 -- Hard 8 -- Very hard (making an effort to keep up) 9 -- Very very hard 10 -- Maximum effort (can't go any further)
Metabolic Equivalent (MET)
- Considered the amount of oxygen required by the body at rest
Power Measurements
Exercise Duration
- Often has an inverse relationship with intensity (longer = less intense, shorter = more intense)
Exercise Progression
How should frequency, intensity, and duration be manipulated to progress aerobic fitness?
None of these factors should increase more than 10% each week
