SIMULATION OF THE RELATIONSHIP BETWEEN EXERCISE AND CARDIOPULMONARY FUNCTION AT HIGH ALTITUDE

ABSTRACT Introduction: Due to various uncertain and unexpected factors in life such as diseases, natural disasters, traffic accidents, congenital disabilities, the number proportion of lower limb amputations are still rising for many reasons, so research on prostheses is particularly important. Objective: This work aimed study relationship between altitude exercise cardiopulmonary function. Methods: A model abnormal changes function was established, then 40 plateau exercisers were selected, all whom arrived Tibet March 2017. The pulmonary circulation volume internal pressure chest observed compared. sensory reflex (high altitude) breathing heart rate analyzed. comparison subjects different genders implemented. Moreover, influence altitudes subjects’ before departure during first, second, third week after Results: I. As thoracic cavity increased, blood gradually decreased, decrease most obvious stage −50 0. II. cardiorespiratory coefficient compensatory acceleration appeared. III. Tracking monitoring indicators revealed that with increase altitude, average arterial pressure, respiratory frequency, showed an upward trend, while oxygen saturation value a downward trend. IV. No matter how high was, rate, monitored under significantly superior indicator values resting state. In contrast, opposite V. respiration, first higher than other periods, but relatively lower. second weeks, smooth (all P<0.05). VI. index small (p>0.05). Conclusion: Through modeling, results environment body made clearer, these data provided theoretical references training sports field area. Level evidence II; Therapeutic studies - investigation treatment results.
