“…Additional studies support the decreased metabolic strain of eccentric exercise 122 and the application of eccentric exercise protocols in patients with cardiac conditions 120 , 123 , 124 , 125 , 126 because improvements in muscle and physical functioning are equivalent to outcomes after standard concentric modes of exercise. The eccentric outcomes, however, can occur at a lower metabolic cost.…”

“…For example, older adults with minimal left ventricular dysfunction and no exertional ischemia exercising eccentrically produced 4-fold greater muscular stress and improvements in the distance walked in 6 min without overstressing the cardiovascular system, that is, at cardiovascular and metabolic levels similar to those observed during concentric exercise. 119 , 120 Similarly, those with severe chronic airway obstruction (e.g., forced expiratory volume <50% of the predicted value) achieved nondamaging, high negative work levels during eccentric ergometry exercise with tolerable levels of leg fatigue and dyspnea compared with concentric ergometry exercise. 121 …”

HighlightsEccentric contractions conform poorly to accepted models of muscle function.The function of elastic proteins, ubiquitous in animal muscle, has been disregarded.Elusive muscle properties are illuminated by including a role for elastic proteins.Scientific inertia has impeded inclusion of titin into the muscle function paradigm.Wrongly thought to inevitably damage muscles, eccentric training has many benefits.

“…In principle, eccentric exercise can be an attractive and feasible alternative to resistance exercise for patients with limited cardiopulmonary exercise tolerance. When exercising eccentrically, adults and older adults with minimal left ventricular dysfunction and no exertional ischemia can produce fourfold greater muscular stress and induce improvement in the distance walked in 6 min without overstressing the cardiovascular system, i.e., at cardiovascular and metabolic levels similar to those observed during concentric exercise (11,79). Similarly, those with severe chronic airway obstruction, e.g., forced expiratory volume Ͻ50% predicted, have achieved nondamaging, high negative work levels during eccentric ergometry exercise with tolerable levels of leg fatigue and dyspnea compared with concentric ergometry exercise (97).…”

This nonexhaustive mini-review reports on the application of eccentric exercise in various rehabilitation populations. The two defining properties of eccentric muscle contractions--a potential for high muscle-force production at an energy cost that is uniquely low--are revisited and formatted as exercise countermeasures to muscle atrophy, weakness, and deficits in physical function. Following a dual-phase implementation, eccentric exercise that induces rehabilitation benefits without muscle damage, thereby making it both safe and feasible in rehabilitation, is described. Clinical considerations, algorithms of exercise progression, and suggested modes of eccentric exercise are presented.

“…Only ankle plantar flexor strength increased significantly more with eccentric training (+17% vs. +7%). In a study of the same laboratory 30 patients with chronic heart failure (ejection fraction <45%; New York Heart Association class 2 or superior) were randomized to a concentric and an eccentric exercise group (Besson et al, 2013). Training was done for 7 weeks, three times per week for 30 min.…”

Over the last 20 years a number of studies have been published using progressive eccentric exercise protocols on motorized ergometers or similar devices that allow for controlled application of eccentric loads. Exercise protocols ramp eccentric loads over an initial 3 weeks period in order to prevent muscle damage and delayed onset muscle soreness. Final training loads reach 400–500 W in rehabilitative settings and over 1200 W in elite athletes. Training is typically carried out three times per week for durations of 20–30 min. This type of training has been characterizes as moderate load eccentric exercise. It has also been denoted RENEW (Resistance Exercise via Negative Eccentric Work by LaStayo et al., 2014). It is distinct from plyometric exercises (i.e., drop jumps) that impose muscle loads of several thousand Watts on muscles and tendons. It is also distinct from eccentric overload training whereby loads in a conventional strength training setting are increased in the eccentric phase of the movement to match concentric loads. Moderate load eccentric exercise (or RENEW) has been shown to be similarly effective as conventional strength training in increasing muscle strength and muscle volume. However, as carried out at higher angular velocities of joint movement, it reduces joint loads. A hallmark of moderate load eccentric exercise is the fact that the energy requirements are typically 4-fold smaller than in concentric exercise of the same load. This makes moderate load eccentric exercise training the tool of choice in medical conditions with limitations in muscle energy supply. The use and effectiveness of moderate load eccentric exercise has been demonstrated mostly in small scale studies for cardiorespiratory conditions, sarcopenia of old age, cancer, diabetes type 2, and neurological conditions. It has also been used effectively in the prevention and rehabilitation of injuries of the locomotor system in particular the rehabilitation after anterior cruciate ligament surgery.

Eccentric training in chronic heart failure: Feasibility and functional effects. Results of a comparative study

Abstract: ECC training tailored by RPE appears to be an efficient and safe alternative for CHF patients. Indeed, it induces functional improvement similar to conventional CON training with lower demand on the cardiovascular system during exercise.
