Before rehabilitation, patients should take an exercise test to eliminate the symptoms of ischemia or arrhythmias, which may require special intervention before physical activity. The load test also allows you to set the initial FN and determine the maximum heart rate for training. These tests are usually performed on the background of prescribed medication to get the heart rate, which is most likely to be during the FN.
Usually, physical training (PT) for cardiac rehabilitation has 3 phases: warm up (5 minutes), workout (20 minutes) and completion (5-15 minutes). Warm up consists of stretching and light gymnastics. Some static load, involving the use of light weights or power trainers, is performed, as a rule, after aerobic exercise as part of the third phase (completion). Exercises such as swinging the biceps, stretching the triceps, pushing up (for patients without problems in the shoulder girdle), shoulders, bending and half-squatting, increase the working capacity of patients to perform work tasks and daily loads, which often require lifting and carrying weights.
Aerobic physical training (PT) is usually performed at the level of 60-70% of VO2max, which corresponds to 70-80% of the maximum heart rate (HR). Lower-intensity FN is recommended for some patients. Although 20-minute FTs are considered standard, even shorter workouts are useful, and longer loads almost certainly provide an additional effect. Most cardiac rehabilitation programs recommend other types of FA: gardening and walking on days when patients do not attend controlled TF.
It is recommended that a stress test be performed prior to cardiac rehabilitation, but not all patients will perform an exercise test, especially after a recent MI. Patients who did not pass the stress test before being included in the program can train with a heart rate of 20 beats / min higher than at rest. Another approach: to train at the level of heart rate plus an additional% of heart rate | for example, for example, for 1 month the patient is trained at the level of heart rate plus 20-30% of heart rate; 2 months – ChSSpokoy plus 20-40% of ChSSpokoy; 3 months – ChSSpokoy plus 20-50% ChSSpokoy. Alternatively, patients can train to have shortness of breath and maintain this level throughout the session. As mentioned earlier, the onset of dyspnea approximately corresponds to the respiratory threshold and is an adequate reference for the load. Finally, patients can train at a fairly high level using quantitative FN scales, specifically designed to assess the intensity of FN, for example, the modified Borg scale.
