I still have a few things assorted concepts I don't understand. If anyone can shed some light- I'd appreciate it!
1) Regarding VO2Max (sorry to beat a dead horse): Generally calculating someone's Karvonen THR to is approx in the range of (120-160) bpm, and that number is the HRR and is equivalent to VO2R and VO2max, why are the normal ranges for VO2 max between about 40 to 60 ml/kg/min (BTW, Lance Armstrong's Vo2max is 84) ? I know I'm missing something important!
2) Difference between Kyphosis and Sway-back - To me they both look like typical "hunchback" and the definitions don't help distinguish the conditions?
3) Motive and resistive forces- In the chapter reivew book "Master the Manual", p.22, I thought in Part 1- Person is flexing elbow- Bicep is motive and gravity is resistive - But correct answers are Pt1- Gravity-Motive, Bicep resistive (how can bicep be resistive and gravity be motive in an upward movement)??
4) Also confused about open vs. closed chain (I know the definitions) but when would you use intentionally choose one over the other?
Apparently Number 1 is the elbow moving eccentrically (towards the back of the person, and Number 2 is the elbow moving concentrically).
It's not obvious from the picture though, I ended up putting a "down" arrow under number 1 to show the direction it's travelling, and an "up" arrow" for number 2 to show it's moving up.
I also get confused by the kyphosis/swayback thing myself w/ the text.
Let us know what they say at ACE about all this stuff :)
Sorry kids! I haven't fogotten these questions!!! I forgot to call Monday and called Tuesday but (my new best friend) April at ACE is out until next Monday!!!

Hi Vonni,
April's great, I've spoken with her also! :)
I'm definitely interested in what she says about those questions.
Hey Vonnie... I called ACE yesterday with some questions, and spoke with Melanie! She was absolutely great! You can try her since April is out. How is your studying coming? Aren't you taking the test on the 21st?

#1) They are in different units- duh! Using karvonen you get bpm and relative VO2max is usually reported as mL/kg/min- so then I asked her if you find a way to convert, will they look the same and she said "they are more comparable in concept". I'm thinking that means you really can't calculate the actual relative VO2max without the oxygen measuring fancy equipment. All you can get is oxygen uptake reserve (equivalent from Karvonen) .
#3) The movement in the book is not a bicep curl (upward) movement at all, it is only a tricep press. That explains how gravity can be a motive force.
