Conditions of aerobic exercise prescription.

<P> According to the American College of Sports Medicine (American College of Sports Medicine) of the statement and conclusions of the study, improve cardiorespiratory fitness exercise prescription, should meet the following criteria: </ P> <P> 1. The movement patterns: < ./ P> <P> any use of the body large muscle groups (Large Muscle Groups), can be sustained for a long time (Can be Maintained Continuously), and has a rhythmic and aerobic forms (Rhythmical and Aerobic in Nature) physical activity; < ./ P> <P> such as: running, walking, swimming, skating, cycling, rowing, cross country skiing, rope skipping and a variety of endurance sports (Endurance Game Activities). .</ P> <P> 2. Exercise intensity: </ P> <P> the pulse number as the index pulse per minute during exercise should be the maximum number of pulse number (can be 220 minus the person's age as a predictor) of .seventy percent to ninety percent range for the appropriate exercise intensity. .</ P> <P> such as a four-year-old normal subjects, the number of his greatest predictive value of pulse hundred and eighty times, and he should be the appropriate exercise intensity pulse of a few hundred and twenty medium in the sixth minute .(180 × 70%) and the second hundred and sixty (180 × 90%) between. .Beyond this range means that the exercise intensity is low or too strong. .</ P> <P> 3. Exercise duration: </ P> <P> to the foregoing the exercise intensity for 20-60 minutes continuously. .Typically, the duration and intensity to be with, if exercise intensity is weak, then the longer duration on the side; the contrary, if the exercise intensity is stronger, the exercise duration to be shorter. .However, the range of adjustment still to be mediated in within the limits specified. .</ P> <P> 4. Exercise frequency: </ P> <P> principle, once every two days of aerobic exercise. .Units such as a weekly rest, at least the implementation of three times a week, for example, three, five, or two, four, six law applied for. .</ P> <P> up is once a day, but this is not absolutely necessary, especially to guard against fatigue caused by lack of rest, or increase the risk of injury. .</ P> <P align=right> (internship Editor: He Lili) </ P>.
