Chapter 16 Strength, Power, and Endurance Training
OVERVIEW.
Active range of motion (AROM, also active assisted range of motion [AAROM]) is movement generated by active muscle contraction and produced within the unrestricted portion of a joint. In active-assisted range of motion, manual or mechanical assistance is provided by an outside force to assist the prime mover through the available joint range.1,2 AROM concerns generally relate to acute cardiac or vascular conditions, stress to unstable or still fragile musculoskeletal or skin tissue (e.g., postop, injuries), or activities that further compromise a structure (e.g., spinal stenosis) (also see ROM assessment).

16.2 Closed Chain Exercise
Closed chain (CC) exercises involve activities where an individual’s proximal body part moves over his or her fixed (i.e., stabilized) distal segment. An example is performing an upper extremity push-up.1 There is some concern for stressing joints, particularly at the knee, while performing squats (a closed chain activity) at certain angles following ACL injuries or repairs.

16.3 Eccentric Exercise
Eccentric exercise is a form of dynamic resistive exercise that involves tension development while the muscle is lengthening.1 Familiar functions involving eccentric activity of the lower limbs include sitting down or descending stairs. Sources identify delayed muscle soreness from microtrauma as a concern following eccentric work.1,2 In more severe cases, rhabdomyolysis may occur.3

16.4 Isometric Exercise
Isometric exercise is a static form of exercise whereby tension develops in the muscle but there is essentially no joint movement. The length of the muscle remains unchanged during the contraction. Three sources identify four cardiovascular concerns for isometric exercise that primarily center around the pressor (increased blood pressure) response (also see Resistive exercise).

16.5 Isokinetic Exercise
Isokinetic exercise is a form of resistive exercise in which a rate-limiting device controls the movement speed of the joint.1 The device is used both for strength testing and exercise. Two sources identified nine concerns for isokinetic exercise, with the largest proportion related to unhealed injuries. Joint and bone instability was a shared concern (see Isokinetic testing, Exercise equipment for complications; also see Resistive exercise).
