This paper reports the changes of the EEG of human bodies during saturation ex-posure at different depths to different mixed gases. The results of the research show thatthe most obvious on EEG was the appearance of diffused slow waves, usually θ wavesof 4- 7 times/s, and δ waves of 2- 3 times/s within individual subjects. The EEG changesat 50 m were more obvious than those at 36 .5 m. With the prolonging of time under highpressure, the EEG had some improvements, for instance, the slow waves decreased andthe α waves increased. There was a certain relationship between these changes and thesymptoms which appeared in the human body. The chief factor of the EEG changes isdue to the effect of nitrogen narcosis during the oxygen-nitrogen diving experiment. Inaddition, carbon dioxide retention under the high pressure is also a factor of the EEGchanges, because repeated inhaling of CO2-dense mixtures could aggravate the EEGchanges and the reduction of carbon dioxide in humans by hyperventilation could

A diving-suit-used foam neoprene with highperformance has been developed and its aging behaviors in QUV accelerated aging tank and temperature cyclic chamber were investigated. The results show that the tensile strength and tear strength of the material are decreased after 9d QUV accelerated aging due to the obvious cracks in the foaming cell. In temperature cycling the mechanical properties increased arising from crosslinking reaction in the aging process. Besides, the chloride ion penetration resistance of the material was tested by dielectric flux intelligent tester, and the result shows that the material is of excellent chloride ion penetration resistance capability. The infiltration coefficient is 8.1×10-11cm2/s.

依附理论(Dependency Theory)是发展社会学的一个重要分支，它从经济和政治的角度，揭示了不发达国家和地区与发达国家和地区之间的不平等依附关系，并在体育研究与旅游研究中有着许多的应用。本文综述性地剖析了社会学、旅游研究与体育研究中的依附于理论，并运用依附理论来讨论了里约奥运会。潜水旅游作为体育旅游与探险旅游的一个分支，也存在着体育与旅游研究中的依附现象。作者综合上述理论分析，提出了潜水旅游中的“外国潜水培训组织–我国潜水专业人士–我国欠发达地区潜水旅游目的地”的“中心–半边缘–边缘”的依附关系，来解读作为体育与旅游融合产物的体育旅游的现象与内涵。

Case Study: EIMS Acupuncture Treatment for Posterior Tibialis Tendonitis

引用

Open Journal of Therapy and Rehabilitation 2015年第4期3卷 126-131页

作者： N. Yelizarov J. Taunton Muscle & Tendon Clinic Richmond Canada Division of Sports Medicine Faculty of Medicine University of British Columbia Vancouver Canada Sports Medicine Fortius Sport & Health Vancouver Canada

BACKGROUND AND OBJECTIVE: Posterior tibialis tendon dysfunction (PTTD) is a progressive ailment of a lower limb that, if left untreated, can lead to irreversible changes in the structure and function. The authors of the present study hypothesized the damages to the tibias tendon can be countered and reversed using electrical acupuncture and concurrent treatment of the associated muscle. INTERVENTION: The following study details a successful treatment of the early stage PTTD in a group of competitive athletes using a specific Electrical Intra Muscular Stimulation (EIMS) protocol developed and rooted in years of practice and the knowledge of the pathophysiology of the muscle and tendon tissues. Specifically, a combination the posterior and the original EIMS approach was used to stimulate the tendon and muscle concurrently at a frequency of 2 Hz. Analysis of the VAS scores showed a significant improvement following the treatment sessions. CONCLUSION: The success of this combined muscle/tendon stimulation protocol is given a strong correlation between the mechanism of tendon and muscle injury and recovery. The fast rate of healing and the simplicity of the materials required for the treatment offer a great potential for a wide-spread application. The authors extrapolate that the treatment method, with applicable modifications in needling locations, can be used for an array of common ailments involving tendons and muscles of the lower limb and foot, including the over-pronation, which is now common place due to the overweight problem in the general population.
