People affected by illness chronicle obstructive pulmonary (COPD) could improve their aerobic capacity while training a leg at a time, according to the findings of a small survey achieved by two researchers torontois1.

Indeed, the dyspnea (short breath) limits the intensity of the exercise that people affected from a COPD can practice greatly. Most train those that must work to low intensity. They therefore do not manage to increase their maximum absorption of oxygen (vO2max).

Chronic bronchitis and emphysema

The chronic bronchitis and emphysema the cause respiratory difficulty was characterized by an obstinate cough and an excess of secretions in the respiratory ways. The medical community assigned them the name of COPD, an illness often irreversible. Generally, the symptoms appear in about fifty, the most often among confirmed smokers.

The researchers compared the performances of two groups of nine affected patients from COPD has followed that practice a stationary bicycle program. At the end of the survey, all participants had increased the intensity of their practice. However, the maximum absorption of oxygen had progressed more at those that had pedaled at a time a leg. They also presented a breakdown maximale2 more elevated.

While exercising itself / themselves at a time a leg, one half would reduce the wage costs asked the organism. The muscular work (on the targeted groups of muscles) would be a little more intense, but the necessary pulmonary effort to arrive there would be least that if one used the two legs at the same time, explain the authors of the survey. This way to proceed would permit to improve the pulmonary and physical condition of people affected thus progressively from COPD.

The participants trained during seven weeks, three times per week, at the rate of 30 minutes by session. Those that had to pedal at a time a leg alternated leg after 15 minutes.
