Previous human studies have also revealed the potential of PEMF to enhance muscle function and athletic performance. To further evaluate this potential, an open label pilot study was conducted with 19 competitive cyclists who repeatedly participated in 63 training routes. Cyclist performance was tracked before and during use of a novel and portable PEMF device that is worn as a wristband. Comparison of performance before and during use of the wristband revealed a significant association with improved muscle power. The odds ratio was 3.02 (P < 0.01) for experiencing increased muscle power while wearing the PEMF device. Among the cycling routes in which an increase was observed, the average increase in power was about 9.8%. The data suggests the novel PEMF technology may be a safe and effective therapeutic approach for improved physical performance and likely involves improved oxygen delivery due to reduced rouleaux (erythrocyte aggregation). These results warrant further investigation comprising larger studies and additional outcomes.展开更多
探讨了低强度脉冲电磁场对兔股骨骨密度及生物力学特性的影响。用27只雌性新西兰大耳白兔随机分为三组(n=9),磁场组暴露于强度分别为10×10-4、20×1-0 4T的脉冲磁场环境中(f=15 H z,=τ5 m s),暴磁时间为6 h.-d 1,对照组饲养...探讨了低强度脉冲电磁场对兔股骨骨密度及生物力学特性的影响。用27只雌性新西兰大耳白兔随机分为三组(n=9),磁场组暴露于强度分别为10×10-4、20×1-0 4T的脉冲磁场环境中(f=15 H z,=τ5 m s),暴磁时间为6 h.-d 1,对照组饲养于线圈中,但不暴磁。6周后处死取股骨,测定骨密度及生物力学特性。结果表明:与对照组比较,磁场组的骨密度、最大载荷及结构刚度差异具有显著性意义(P<0.05);其中,两个磁场组之间作比较,骨密度及结构刚度差异显著(P<0.05)。低强度脉冲电磁场能改善股骨的骨密度和生物力学性质,其生物效应存在明显的窗口效应,对骨质疏松症的预防和治疗提供了新的思路。展开更多
