Document Summary
Hped 375 chapters 4, 11, and 15 study guide. Examples: upward neck stretch, tricep extension: 2nd - fulcrum in 1st position, resistance (closer) and muscle action (farther) immediately followed. Examples: standing calf raise, baseball swing: 3rd resistance in 1st position (farther), muscle action in 2nd (closer), fulcrum last. Understand the principle of mechanical advantage (moment arm, variations in tendon insertion) know how it applies to a person and a machine (exercise machine: mechanical advantage. The applied force is greater than the resistive force ( > 1) Applied force / resistive force > 1: mechanical disadvantage. The applied force is less than the resistive force ( < 1) Applied force / resistive force < 1. Planes of movement , axis of rotation and movement associated with each plane: sagittal left and right sides, frontal forward and backward; abduction and adduction, transverse rotation (torque) Know of the biomechanical factors of strength (specifically neural control, cross- sectional area,
