force produced. An experiment was conducted on bicycle riding. The amount of oxygen consumption was measured during the motion of pedaling forward as positive work and pedaling with resistance as negative work. Less oxygen was consumed during negative work than of positive work with the oxygen consumption ratio being 3:7. Due to the low oxygen consumption of eccentric exercise studies have been conducted on patients with severe COPD. An eccentric cycling exercise workout was created for these patients and the results found there to be no side effects, minimal muscle soreness that had no effect on power, and high compliance. Furthermore, other cycling studies concluded that eccentric cycling was a safe alternative for COPD patients as they can perform high-intensity work with lower cost.

While typically these disorders are directly related to eccentric muscle movements, the ability of a muscle to strengthen and prevent injury through eccentric training is great. Controlled rehabilitative regimes will actually strengthen and repair tendons. Ample evidence supports the notion that the tendon, like the muscle, can adapt favorably to 439:
by people afflicted with the above disorders and many cannot participate in rigorous exercise protocols. Eccentric muscle contractions produce high forces with low-energy costs. According to Hortobágyi due to these properties, eccentric exercise has the greatest potential for muscle strengthening. To strengthen muscle the external force must exceed the muscle while it lengthens. The definition of

after twenty sessions of treadmill low-intensity eccentric training the wet weight of the muscles and the fiber cross-section was significantly larger than the control and level groups. These results led to the conclusion that low-intensity eccentric contractions have the ability to "produce enough mechanical stress to induce

A lot of studies have been conducted regarding eccentric exercise over the last decade. It can be said there is substantial evidence that eccentric exercise truly exceeds concentric exercise for rehabilitation and training aspects in force, energy cost, oxygen consumption, and muscular strengthening.

Greater mechanical stress brought on by eccentric contractions is what leads to hypertrophy in individuals undergoing eccentric training. Studies done on

Eccentric exercise or resistance training is currently being used as a form of rehabilitation for sports injuries, but also as an alternative form of exercise for the elderly and those affected by neurological disorders, COPD, cardiopulmonary disorders, and cancer.
