Of cardiorespiratory endurance

The sports therapist should routinely incorporate activities that will help maintain levels of cardiorespiratory endurance into the rehabilitation program. Cardiorespiratory endurance involves the coordinated function of the heart, lungs, blood, and blood vessels to supply sufficient amounts of oxygen to the working tissues.

The best indicator of how efficiently the cardiorespiratory system functions is the maximal rate at which oxygen can be used by the tissues. Heart rate is directly related to the rate of oxygen consumption. It is therefore possible to predict the intensity of the work in terms of a rate of oxygen use by monitoring heart rate.

Aerobic exercise involves an activity in which the level of intensity and duration is low enough to provide a sufficient amount of oxygen to supply the demands of the working tissues. In anaerobic exercise the intensity of the activity is so high that oxygen is being used more quickly than it can be supplied, thus an oxygen debt is incurred that must be repaid before working tissue can return to its normal resting state.

Continuous or sustained training for maintenance of cardiorespiratory endurance involves selecting an activity that is aerobic in nature and training at least three times per week for a time period of no less than 20 minutes with the heart rate elevated to at least 60% of maximal rate.

Interval training involves alternating periods of relatively intense work followed by active recovery periods. Interval training allows performance of more work at a relatively higher work load than continuous training. During rehabilitation, continuous and interval training techniques should be incorporated.

Fartlek makes use of jogging or running over varying types of terrain atchanging speeds. Par cours is a training technique that combines continuous training with exercises done at stations along the course.
