The onset of muscular fatigue and the patterns of exercise and postcontraction hyperemia, oxygen consumption and lactate release were examined in 50 male patients with essential hypertension, doing hand grip with an effort amounting to 5% of their maximum unrestricted potential. Subgroups of patients with normal and rapid onset of forearm muscular fatigue were identified. Unlike normal subjects and hypertensive patients with normal onset of muscular fatigue, patients with increased muscular fatigability demonstrated a progressive increase rather than stabilization of blood flow rate, oxygen consumption and lactate release which continued until the patient gave up exercise. Different patterns of blood supply, energy metabolism and muscular fatigability are believed to result from changed vascular resistance.
对50名原发性高血压男性患者进行了研究，让他们以相当于其最大无限制潜力5%的力量进行握力运动，检测肌肉疲劳的发作情况以及运动和收缩后充血、耗氧量和乳酸释放的模式。确定了前臂肌肉疲劳正常发作和快速发作的患者亚组。与正常受试者和肌肉疲劳正常发作的高血压患者不同，肌肉易疲劳性增加的患者表现出血流率、耗氧量和乳酸释放逐渐增加而非稳定，这种情况一直持续到患者放弃运动。据信，不同的血液供应、能量代谢和肌肉易疲劳性模式是由血管阻力变化导致的。
