You are floating motionless in outer space. Your mass is 70 kg. Your 70 kg transporter floats by and you attempt to bring in closer by flexing your right arm. Are you more likely to produce an isotonic or isometric contraction? Explain.

Answer 1

Since this is not my area of expertise, I searched Google under the key words "isotonic isometric contraction" to get these possible sources:

http://en.wikipedia.org/wiki/Muscle_contraction
http://www.weightlossforall.com/exercise-types.htm
http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/M/Muscles.html#isotonic

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps.
