TYPE OF RESISTANCE EXERCISE

            Type Of Resistance Exercise

Manual Resistance Exercise
Mechanical Resistance Exercise

Manual resistance exercise is a type of active-resistive
exercise in which resistance is provided by a therapist or
other health professional. A patient can be taught how to
apply self-resistance to selected muscle groups. Although
the amount of resistance cannot be measured quantitatively 

Mechanical Resistance Exercise

Mechanical resistance exercise is a form of active-resistive equipment or mechanical apparatus. The amount of resistance
can be measured quantitatively and incrementally progressed over time.

It is also useful when the amount of resistance necessary is greater than what the therapist can apply manually.

Isometric Exercise (Static Exercise)

 which a muscle contracts and produces force without an appreciable change in the length of the muscle and without visible joint motion.

 Although there is no mechanical work done (force  distance), a measurable amount of tension and force output are produced by the muscle.

 Sources of resistance for isometric exercise include holding against a force applied manually, holding a weight in a particular position, maintaining a position against the resistance of body weight, or pushing or pulling an immovable object

Indication 

• To prevent or minimize muscle atrophy
 when joint movement is not possible owing to external immobilization(casts, splints, skeletal traction)
• To activate muscles (facilitate muscle firing) to begin to re-establish neuromuscular control
 but protect healing tissues when joint movement is not advisable after soft tissue injury or surgery
• To develop postural or joint stability
 To improve muscle strength when use of dynamic resistance exercise could compromise joint integrity or cause joint pain
• To develop static muscle strength at particular points in the ROM consistent with specific task-related needs

Types of Isometric Exercise

 Muscle-setting exercises. Setting exercises involve low intensity isometric contractions performed against little to no resistance. 

They are used to decrease muscle pain and spasm and to promote relaxation and circulation after

     injury to soft tissues during the acute stage of healing.

    Two common examples of muscle setting are of the quadriceps and gluteal muscles.

setting exercises can retard muscle atrophy and maintain mobility between muscle fibers when immobilization of a muscle is necessary to protect healing tissues during the very early phase of rehabilitation.

Stabilization exercises
. This form of isometric exercise is used to develop a submaximal but sustained level of cocontraction to improve postural stability or dynamic stability of a joint by means of mid-range isometric contractions

    against resistance in antigravity positions and in weight bearing postures if weight bearing is permissible.

They include rhythmic stabilization and alternating isometrics, two techniques associated with proprioceptive neuromuscular facilitation (PNF).

Multiple-angle isometrics. 

This term refers to a system of isometric exercise where resistance is applied,

 manually or mechanically, at multiple joint positions within the available ROM. 

This approach is used when the goal of exercise is to improve strength throughout the ROM when joint motion is permissible but dynamic resistance exercise is painful or inadvisable.
