Isometric contraction - Study guides, Class notes & Summaries

Where should the examiner place their hand during MMT? - ️️- in a position that maximizes mechanical advantage by increasing moment arm of your resistance force (*think class 3 lever) -to resist the patient isometrically, the amount of torque you apply must match the amount of torque the patient applies (this is static equalibrium) How would you use 3D motion capture to quantify how much "sway" a concussed participant has during gait? - ️️You measure a persons' center of m...

1. What are the 3 types of muscle contraction?: AND Isometric, Eccentric, & Concen- tric Isometric produces force, but there is no change in muscle length. Concentric produces enough force to overcome external load and shorten the muscle Eccentric produces force while the muscle is lengthening - it is the resistance of a movement. 2. The nervous system should be properly trained upon beginning an exercise program because: A. It decreases the risk of injury B. It improves stamina C. It all...
