This study examined the effect of strenuous short-term dynamic exercise on the heart rate, blood pressure, plasma potassium and packed cell volume in mildly hypertensive subjects. At baseline a symptom-limited Bruce Exercise Protocol was carried out with blood pressure, heart rate, plasma potassium and packed cell volume measurements at fixed time points at rest and during and after the exercise. After 6 weeks of taking exercise sessions (Bruce protocol) to fatigue three times a week, the subjects were restudied. Blood pressure and the heart rate fell significantly at rest and during and after exercise. The packed cell volume was higher at all study points and plasma potassium was higher in the postexercise period after the exercise conditioning. Strenuous short-term exercise has a beneficial antihypertensive effect, raises packed cell volume and has a favourable effect on plasma potassium homeostasis.
本研究调查了剧烈短期动态运动对轻度高血压患者心率、血压、血浆钾和红细胞压积的影响。在基线时，采用症状限制的布鲁斯运动方案，在静息、运动期间及运动后固定时间点测量血压、心率、血浆钾和红细胞压积。在每周进行3次运动训练（布鲁斯方案）直至疲劳6周后，对受试者再次进行研究。静息、运动期间及运动后，血压和心率显著下降。在所有研究点，红细胞压积均较高，且运动训练后的运动后阶段血浆钾升高。剧烈短期运动具有有益的降压作用，可提高红细胞压积，并对血浆钾稳态产生有利影响。
