Equipment Modalities

Types of Resistance

Isometric Can product strength gains up to a point, when maximum force is being produced. Effective in exercising injured joints. Little muscular endurance, must be performed at all angles to increase strength.
Dynamic Constant Resistance Resistance force determines the muscle force. Resistance occures through both concentric/eccentric phase. Weight load does not change.
Dynamic Variable Resistance Strength training using weight stack machines have variable resistance. Weight load changes automatically during the movement. Less resistance in weaker phase, more resistance in the stronger phase.
Strength Curve Most difficult point in muscle contraction is called the sticking point. Maximum amount of weight a person can lift in a dynamic exercise is equal to the maximum weight that can be lifted through the sticking point.
Isokinetic Cannot adjust speed. Maximum resistance can occur through full ROM regarless of speed of contraction.
Computer Controlled Example: Lifecircuit. Popular with beginners, seniors and disabilities. Dynamic resistance. My be intimidating, requires more in-depth instruction.
Space & Equipment Layout Space required is 100 sq. ft. per person. Machines require 20 sq. ft. per person.
