-Major problem associated with tests that require performance to fatigue
point of fatigue is highly influenced by the client’s motivation
test that measures upper body endurance of pectoralis muscles, triceps and anterior deltoids

Lack of accuracy related to estimated maximal oxygen uptake – 2 variables:
- Calculations based on 220 – age equation. + or – 12bpm
- Based on assumption everyone expends same amt of energy AND uses the same amt of oxygen…submaximal will underestimate or overestimate the true maximum for the client
-at near maximal intensities anaerobic glycolysis causes 2
- Increase in carbon dioxide

2 ways to explain body comp testing in lay terms
measures how much fat you have in proportion to the weight of muscles, bones and tissue
% of your weight that is fat compared to fat free weight - muscles, bones, tissues

TOBEC
To figure weight at certain body fat percentage:
Example weighs 180 lb at 20% BF
What will weight be at 15% BF
Figure lean mass first
100% - Current BF% 20 = 80%
180lbs x .80 = 144 LBM
100% - 15% = 85%
144/ 0.85 = 169 lbs
to predict HR response at VT2
perform in _phase of CR IFT moddel
