Low-intensity electrical muscle stimulation induces significant increases in muscle strength and cardiorespiratory fitness

The aim of this study was to investigate the effect of low-intensity exercise training using belt electrode skeletal muscle electrical stimulation on muscle strength and cardiorespiratory fitness in healthy subjects. Nineteen healthy subjects were allocated into control or intervention groups; in both groups the participants kept regular physical activity while the intervention group underwent 30 min B-SES training at 3–4 METs for four weeks. Knee extensor muscle strength and cardiorespiratory endurance during incremental exercise test were measured at baseline and after four weeks for all participants. The relative change of knee extensor muscle strength in the intervention group was significantly higher than control group (p?p?相似文献

The role of social embeddedness in professorial entrepreneurship: a comparison of electrical engineering and computer science at UC Berkeley and Stanford

Professorial entrepreneurship has recently attracted much attention. This paper draws upon historical research, a survey of faculty, and an Internet-based methodology for identifying professorial affiliations with entrepreneurial firms at two of the premier electrical engineering and computer science departments in the US, The University of California, Berkeley and Stanford. We employ the concept of “nested embeddedness” to explain why the faculty members in these two institutions have different levels of entrepreneurship and corporate involvement. EE&CS faculty at both universities were found to be socially embedded in departments and disciplines that supported and placed value on entrepreneurial activities. However, while being embedded in a university environment with a history of success and high level of support for entrepreneurship, EE&CS faculty at Stanford had a significantly greater level of corporate involvement, including the founding of start-ups. Although significantly less than Stanford, the level of corporate involvement among EE&CS faculty at Berkeley was also substantial. This suggests that being embedded in an academic department and disciplines with cultures that are supportive of entrepreneurial activity can help counteract the disincentives created by a university environment that is not strongly supportive of these activities.

电刺激干预腓肠肌拉伤后成肌调节

目的：采用低强度电刺激治疗腓肠肌拉伤,观察其对于肌肉损伤部位成肌调节因子MyoD与Myogenin蛋白表达的影响。方法：雄性SD大鼠32只,随机分为对照组、模型组、D14组和D14-40Hz组。除对照组外其余各组建立腓肠肌拉伤动物模型。于造模后第5天D14-40Hz组开始予以电刺激,其余组继续喂养。正常对照组在实验开始当天,模型组在造模当天,D14组和D14-40Hz组在第14天进行在体力矩测试,测试结束后处死动物,分离腓肠肌采用免疫印迹法（Western blotting）测定MyoD与Myogenin蛋白表达。结果：对照组关节最大等长力矩值为0236±0045（Nm）,模型组肌肉拉伤后即刻关节最大等长力矩下降为0176±0034（Nm）,两者比较存在显著性差异（P＜005）;第14天D14-40Hz组最大等长力矩值为0247±0038（Nm）,与D14组比较存在显著性差异（P＜005）。MyoD与Myogenin蛋白表达测定结果：肌肉拉伤后第14天MyoD蛋白表达D14组与对照组比较无差异（P＞005）,但是MyoD蛋白表达D14-40Hz组比D14组增强明显（P＜005）;肌肉拉伤后第14天,D14-40Hz组Myogenin蛋白表达明显强于D14组（P＜005）。结论：腓肠肌急性拉伤后,早期采用低强度电刺激治疗可以明显提高关节力矩,并促进了MyoD与Myogenin的表达,对组织修复起到了积极地作用。
