Abstract [en]

Congestive heart failure often develops gradually over a long period and is especially common in older people (10%). Most patients with heart failure suffer from fatigue and breathlessness, which often leads to a decreased exercise dose and lower physical performance. As a result, these persons have a reduced muscle strength resulting in decreased quality of life and ability to live independently. The purpose of this essay is going to review studies using eccentric training on patients with congestive heart failure. Our purposes are 1) explore why eccentric exercise is superior to concentric exercise with respect to mechanical stimulation on muscle and metabolic stress on heart; 2) to reveal whether eccentric training is an ideal training method for patients with congestive heart failure; 3) to explore the mechanisms of the positive effects of eccentric training on the populations.Evidence from previous studies on healthy people suggested that the eccentric contraction induces three to four times higher mechanical stimulation on muscle than concentric contraction, indicating eccentric exercise is more effective than concentric exercise in increasing muscle strength. For a given load eccentric muscle contraction consumes about 1/6 as much ATP as a concentric muscle contraction, suggesting that less oxygen is required to rebuild ATP, which in turn places less demand on the circulation.Research on patients with heart failure proved that eccentric exercise is more effective in increasing muscle strength than concentric exercise, thus more effective in improving life quality of the population. Eccentric exercise also induces less metabolic stress on the heart of the population, therefore lower risk of heart attack or other serious heart diseases triggered by physical training. Eccentric strength training is then considered to be preferable for patients with congestive heart failure due to its positive effects regarding increased muscle strength with less demand on metabolism compared to concentric strength training.
