Chapter 24: Fitness & Therapeutic Exercise

Isotonic Exercise

Involves movement and work

The muscles being exercised shorten and lengthen

Aerobic: example of isotonic exercise: promotes cardiorespiratory conditioning and increases lean muscle mass

Isometric Exercise

Stationary exercise during which there is no change in length of the contracting muscle; usually against resistance

Repeatedly tensing and relaxing muscles

Increases muscle mass and strength

Improves circulation but does NOT promote cardiorespiratory function

Isokinetic Exercise

Combines movement at a constant speed with a form of resistance

The speed and resistance is preprogrammed and controlled with a machine

Often used for rehabilitation

Therapeutic Exercises

Activity performed by people with health risks or those being treated for an existing health problem

-Prevents complications and restores lost function

-Isotonic or isometric

*For isotonic, may be active or passive exercise

Continuous Passive Motion Machine

Mechanical device powered electrically as a supplement or substitute for manual ROM- clients with burn injuries or knee'/hip replacement surgery

Produces 0*-110* motion, 2 to 20 times a minute

Initial setting is very low and is increased each day

ROM exercises

Flexion, extension, hyperextension, abduction, adduction, rotation, external rotation, internal rotation, circumduction, pronation, supination, plantar flexion, dorsiflexion, inversion, eversion
