电刺激增强或维持肌肉功能已得到较好证实。但对人体肌纤维的募集顺序仍不清楚。本文报告一例用电刺激确定骨骼肌纤维激活顺序的研究结果。受试者男性,31岁,身高181.5cm,体重81.6kg。健康,无左髋、膝外伤或疼痛,无葡萄糖不耐受、糖原贮存病或其它代谢疾病史。在刺激前先最大限度地耗尽股四头肌糖原贮存,再最大限度地使之得到补充。消耗运动的前几天,用 CybexⅡ型等动肌力计测受试者最大随意等长力矩(MVIT),做三
Electrical stimulation to enhance or maintain muscle function has been well confirmed. However, the order of recruitment of human muscle fibers remains unclear. This article reports a case of electrical stimulation to determine the order of activation of skeletal muscle fibers. Subject male, 31 years old, height 181.5cm, weight 81.6kg. Healthy, without left hip, knee injury or pain, no glucose intolerance, glycogen storage disease or other metabolic disease history. Maximize depletion of quadriceps glycogen storage prior to stimulation to maximize replenishment. A few days before the consumption of exercise, with Cybex Ⅱ type isokinetic test subjects maximum voluntary moment (MVIT), do three
