Specific Weight- weight per unit of volume

Anterior – toward front of the body

Posterior – toward back of the body

Sagittal plane – in which forward and backward movement occurs

Joint flexibility – relative ranges of motion allowed at a joint in different directions

Joint stability – ability of a joint to resist abnormal displacement of the articulating bones

Weight bearing exercise – exercise that involves stress on the body to bear weight

Stress – force unit of area over which the force acts

Rectilinear – along a straight line

Abduction – movement away from the midline

Radial deviation – deviation of the wrist towards the radius

Ulnar deviation – deviation of the wrist towards the ulna

Skill Drills

Squat - squatting builds joint stability and joint flexibility, your quads and hamstrings which effectively improves all three of these skills because it allows you to remain in your offensive line stance for longer periods of time.

Jammer - the jammer is a free weight machine that imitates the motion of the punch to the defender in both the run block and down block, this builds strength and speed behind the punch.



Medicine Ball Throws - medicine ball throws helps to build the habit of keeping the hands up, speed, and strength behind the punch of a pass set.

Run Block - Prep

Before a play an offensive lineman would stand at the line of scrimmage, this is the prep phase, seen from the sagittal plane, before getting into his offensive line stance.

Run Block - Stance

Athlete then gets into his offensive line stance. Athlete will keep a stagger with his left foot anterior and right foot posterior, with his feet abducted shoulder width apart. Knees bent in a squat-like position. His back will be straight, shoulder blades depressed to keep head up and hand extended out in front of him onto the ground.

Run Block - 1st Movement

Athlete will take his 1st step with his right foot. Heel replacing toe and keep foot dorsiflexed during each step.  Arms will be hyperflexed keeping the elbows tight, and hands in radial deviation (in the "hip pockets.") Athlete should keep an athletic knee bend with his back straight.

Run Block - 2nd Movement

Athlete will then take a 2nd step with the left leg, keeping his neck flexed so that his head is up. Elbows are still adducted together, arms are flexed and hands are still in the middle of the chest . Athlete should still have the same knee bend and straight back.

Run Block - Finish

 

Athlete will then deliver a blow with his hands applying his maximum amount of force by fully extending his arms. This will be where the athlete takes on the specific weight of the defender.
