Decrease in VO2Max about 10% per decade between 20 and 69 for both genders
Absolute vs Relative VO2
Various Predicted HRmax Equations
APMGR = 220 - age
Tanaka, Monahan & Seals: HRmax = 208 - (0.7 X age)
InBar: HRmax = 205.8 - 0.685 X age
Londerdee & Moeschberger: HRmax = 206.3 - (0.711 X age)
Whyte et al. Men: 202- (0.55 X age) women: 216: - (1.09 X age)

Aerobic Sub-maximal testing assumptions
A linear relationship exists between VO2 (workload, O2 uptake) and HR.
Maximum HR which must be predicted for submaximal testing, can be estimated or predicted as a function of age (HRmax = 220 - age).
The mechanical efficiency for the cycle (50 rpm) and treadmill protocols are constant for all individuals.
The HR at two separate work outputs can be plotted as the HR-VO2 relationship and extrapolated to the estimated HRmax linked (to the first assumption).
Pros and cons of choosing a bike protocol for your submaximal aerobic test
Limitations to choosing the Bike Protocol
Requires leg power so if the client has limited leg power, will have to stop the test prematurely.
Bike seat may not be comfortable.
Biking is not a natural motion, unlike walking/running and requires a learned mechanical motion.
Advantages to choosing the bike protocol
Obtain palpation HR.
Easier to take BP.
Easier to conduct ECG.
If the client is obese.
If I have an injury that can be made worse from impact activity.
When does YCMA test end?
When participant reaches within 10bpm of their 85% HRmax
