1. Chapter 3 Biomechanics of Resistance Exercise Anatomical Position Planes & Axis –Sagittal, Frontal, Transverse Flexion & Extension, Aduction, Abduction, Agonist & Antagonist Axial & Appendicular Skeleton –Levers at work –Class 1, Class 2 & Class 3 Fulcrum, Moment Arm (Pg 33), Lever Example – Does the weight & mass of barbell remain equal throughout the lift.

2. Chapter 3 Terms and Equations associated with Axial Skeletal movement –Torque = Magnitude of Force which changes based on the angle of the joint –Work = Force x Distance Squat Example & Valsalva –Power = Work divided by time P=W/T

3. Chapter 3 Strength/Mass Ratio –Same cross sectional area but lower body weight equals more strength (classic formula) Which athlete is the strongest: –1. Body Wt. 250 can bench press 495 –2. Body wt. 190 can bench press 375 –3. Body wt. 160 can bench press 310 –4. Body wt. 150 can bench press 270 –If muscle is slightly stretched or preloaded prior to event you’ll see an increase in strength

4. Equipment used to enhance strength Advantages of Weight Machines –Safer, design flexibility, quicker, ease of use Advantages of Free Weights –Whole body training –Simulate real life situations –Lower cost Notable problems with band machine & Plyobands.

5. Chapter 3 Lifting belts, Body Suits and Knee Wraps
