Thread: Biomechanics

Hi,
As i am new here and the first message that came up was to either introduce myself or ask a question, i am choosing the second one although i am not sure if the threads has to be grouped. Please correct me if i am wrong.

I was wondering if someone can help me find out what kind of system class the following exercises are:
1) knee extension
2) bench press
3) squat with and without external weight.

Thank you in advance.

Regards.

Not sure what you mean by "system class". You mean pronation, supination, flexion, extension, etc?

Hei,
No, i mean as in the 1,2 and 3. class levers. This system gives you a picture on how external and internal forces are places. The someone can calculate r: momentarm, and by having a given force someone can calculate the torque.
For some reasons i cannot post a link, so please google lever class system.

I am struggling finding out which system can reflect the exer. i mentioned.
So far bench press is a 3.class lever system
