Impact of Novel Pulsed Electromagnetic Field Device on Competitive Athlete Performance

The interaction of pulsed electromagnetic fields (PEMF) with the human body may result in a variety of positive outcomes including analgesia, enhanced healing, chondroprotection, cognitive improvement and better quality of life. 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.

Perceived Improvements of Quality of Life (QoL) among Patients with Idiopathic Pulmonary Fibrosis (IPF) in Response to a 6-Week Rehabilitation Program

Idiopathic pulmonary fibrosis (IPF) is a chronic, life-limiting with an average life expectancy of 05 years following the onset of the disease, with no curative treatments. These patients need palliative care and rehabilitation is one of the methods that can be used to improve quality of life (QoL) among these patients. Yet the research conducted to assess benefits of pulmonary rehabilitation (PR) in terms of improving physical activity and QoL in IPF patients remains limited. Hence this study aims to evaluate the effect of a bespoke pulmonary rehabilitation programme, on the physical, physiological and psychological parameters and improvements of QoL among IPF patients. Eleven (11) subjects with IPF received 6 weeks of pulmonary rehabilitation. An interviewer administered quality of life questionnaire, six-minute walking test (6MWT), Incremental bicycle exercise tests were performed, and cardiac and respiratory parameters were assessed pre- and post-rehabilitation. The 6MWT was significantly increased following training (Pre 312.55 ± 89.99;Post, 380.73 ± 59.60). A significant improvement was observed in overall QoL (2.226 ± 0.026), dyspnoea (-0.455 ± 0.004) anxiety (-2.070 ± 0.038), depression (-2.217 ± 0.027) scores. No significant changes were found in the VO2 max and other cardiopulmonary parameters, while non-significant improvement was seen in SpO2 at peak exercise from 85.8 - 86.5. Bespoke pulmonary rehabilitation program is beneficial in short term improvement of the functional exercise capacity, dyspnoea and QoL among IPF patients.

4分钟快速功率车测试对2型糖尿病患者心肺耐力检测价值的研究

目的探讨一种针对T2DM患者相对便捷、准确的最大摄氧量(VO_(2)max)测试方法。方法选取2019年3月至2020年11月于东南大学附属中大医院内分泌科住院的T2DM患者51例,采用YMCA功率车(YMCA)和本研究设计的4 min快速功率车测试心肺功能。通过YMCA测试得到VO_(2)max标准值;4 min快速功率车测试男性从60瓦(W)开始,女性从30 W开始,每30 s增加10 W,持续4 min测试完成后,通过既有公式计算VO_(2)max。结果通过既有公式所得4 min快速功率车测试的VO_(2)max高于YMCA测试结果,二者高度相关(r=0.80),通过构建线性方程得到4 min快速功率车的VO_(2)max推算公式,所得结果与YMCA结果相比,一致性较好。结论采用4 min快速功率车测试,采用特定算法计算VO_(2)max,可有效反映T2DM患者心肺功能。
