为了研究脊髓灰质炎后肌肉的适应性，12名受试者(平均年龄54岁)参加了高强度阻力训练计划。75%的人符合脊髓灰质炎后综合症的标准。测量等长、等速力量和肌肉耐力。在肌肉活组织检查中发现了受脊髓灰质炎影响的肌肉。活检组织还用于酶活性的测量以及组织化学和组织病理学分析。训练前强度值不到健康对照组的一半，平均纤维面积是健康对照组的两倍，氧化酶活性低。训练后，等长力量(平均29%)和等速力量(平均24%)显著增加，并保持了一段时间。这证明了已经从长期存在的脊髓灰质炎中得到补偿的肌肉仍然具有适应性。
To study the adaptability of postpolio muscles, 12 subjects (mean age 54 years) participated in a high-intensity resistance exercise program. Seventy-five percent met the criteria for postpolio syndrome. Isometric and isokinetic strength and muscle endurance were measured. Polio-affected muscles were identified in muscle biopsies. The biopsies were also used for measurements of enzymatic activities and for histochemical and histopathologic analyses. Pretraining strength values were less than half those of healthy controls, mean fiber areas were twice those of healthy controls, and oxidative enzyme activity was low. After training, a significant increase in isometric (mean 29%) and isokinetic (mean 24%) strength was observed and maintained for some time. This demonstrates remaining adaptability in muscles already compensated from long-standing polio.
