Alignment | Isolated Lever | Sports Conditioning
Alignment
- Position body segments according to anatomical principles and Functional conditioning
- Kinetic chain
- Plane of motion in line with force vector
- Rotary motion(s) of target muscle group(s) oppose(s) resistive force
- Supporting chain
- Posture conducive to function and safety
- Position for stability
- Adjust body orientation
- target desired muscle groups
- modify angle of pull conducive to training objectives
- Kinetic chain
- Take note of subtle difference of postures and movements
- effect on joint and muscle involvement
- effect on efficacy, safety, and specific adaptation
- Analysis and correction
- Coaching and Training
- Address Biomechanical Deficiencies which may affect ideal exercise form
- Visual and kinesthetic feedback
Isolated Lever machines
- eg: Lever Leg Curl
- Understand Scapulohumeral Rhythm when aligning machine's fulcrum with exercises involving shoulder girdle
- Accommodating Secondary Lever or Roller
- Pivot point of joint may not have to be positioned exactly in line with machine's primary fulcrum
- Secondary lever or roller will dynamically articulate to accommodate varying lever body segment lengths and positions
- Roller example
- Accommodating secondary lever examples:
- Lever Arm Curl
- Cybex Triceps Extension
- Cybex Eagle Triceps Extension
Sports Conditioning
- Exercises should mimic biomechanics practiced in activity
- Coaches emphasize bench press for upper body strength
- In actuality, upper body training should emphasize the Jerk or Military Press and Incline Bench Press
- Pushing while blocking is performed with the body angled into the opponent to maintain balance while maximizing force (See Factors Increasing Stability )
- Not upright with arms at a transverse plane (like Frankenstein running at you)
