士兵体能训练卫生规范

以部队装备和士兵体质现状为基础，制定了士兵体能训练卫生规范。《规范》主要规定了以下三部分内容：①部队士兵进行基本体能训练应遵循循序渐进、超负荷训练及适宜恢复等生理卫生要求；耐力、力量和柔韧性训练的方式、强度和时间；体能训练的组织实施等，以使体能训练负荷与机体的生理状态相适应；②体能训练的卫生监督，针对体能训练中可能遇到的医学问题进行监督，能够防止训练伤、过度疲劳及其它医学事故的出现，保障体能训练的顺利进行；③体能训练的医学效果评价。本标准适用于陆军部队士兵基本体能训练。海、空军地勤部队士兵的体能训练亦可参照执行。     

How Can and Do Australian Doctors Promote Physical Activity?

Background.Physical inactivity is recognized as an important public health issue. Yet little is known about doctors' knowledge, attitude, skills, and resources specifically relating to the promotion of physical activity. Our survey assessed the current practice, perceived desirable practice, confidence, and barriers related to the promotion of physical activity in family practice.Methods.A questionnaire was developed and distributed to all 1,228 family practitioners in Perth, Western Australia.Results.We received a 71% response (n= 789). Family practitioners are most likely to recommend walking to sedentary adults to improve fitness and they are aware of the major barriers to patients participating in physical activity. Doctors are less confident at providing specific advice on exercise and may require further skills, knowledge, and experience. Although they promote exercise to patients through verbal advice in the consultation, few use written materials or referral systems.Conclusions.There are significant differences between self-reports of current practice and perceived desirable practice in the promotion of physical activity by doctors. Future strategies need to address the self-efficacy of family physicians and involve resources of proven effectiveness. The potential of referral systems for supporting efforts to increase physical activity by Australians should be explored.     

长期居住海平面后藏族经受急性减压低氧时的体力活动能力

本研究从急性低氧对移居海平面后藏族的体力活动能力的影响来探索藏族的高原低氧适应机制。结果揭示藏族的最大体力负荷强度没有显著下降，最大氧耗和氧脉搏也没有明显变化，动脉血氧饱和度明显高于汉族，这更显示藏族对高原低氧适应机制有独特之处。推测可能是藏族在氧的摄取、传递和释放过程比汉族更有利于对高原低氧环境的适应。     

平板玻璃厂工人体力劳动强度的调查

本文对平板玻璃厂工人体力劳动强度的调查结果表明,该厂9个工种的平均劳动时间率为58%(18～83%);8小时工作日平均耗能为7010kJ/man(4043～9190)。在所调查的9个工种中,劳动强度属Ⅰ级占33.3%,Ⅱ级占44.4%,Ⅲ级占22.3%。与其它玻璃制品行业比较,平板玻璃厂主要特点是劳动耗能量大,工时利用率低。为此,建议今后应改进生产工艺与劳动条件,合理劳动定额、定员,提高工时利用率,降低体力劳动强度。     

112名运动员尿17-羟、17-酮调查及3年追踪观察

作者对8个项目112名运动员进行了尿17羟皮质类固醇、17—酮类固醇24小时排量的检查。结果表明:运动员的肾上腺皮质分泌功能均大于正常对照组,差异有显著性。另外,随运动项目和训练年限的不同,肾上腺皮质分泌功能亦有差异。     

Physical activity consultation for people with Type 2 diabetes: evidence and guidelines.

Physical activity is an important, but often underused, therapeutic strategy within diabetes care. To date, little is known about the best way to promote physical activity in diabetes care. Physical activity consultation is an intervention designed to promote physical activity behaviour change. This article provides guidelines on how to conduct a physical activity consultation with people who have Type 2 diabetes, and reviews the evidence surrounding the effectiveness of this intervention in this population. The trans-theoretical model is the underlying theory of behaviour change for the physical activity consultation intervention. The review identifies research which supports the use of this model for understanding physical activity behaviour in people with Type 2 diabetes. The review outlines a number of modifiable variables associated with physical activity behaviour change in this population. How each of these variables is addressed within the guidelines for conducting a physical activity consultation is identified. Finally, limited but consistent research highlights the effectiveness of physical activity consultation for promoting physical activity in people with Type 2 diabetes.     

对儿童X线体检中减少照射剂量的探讨

目的:探讨儿童在X线体检中减少照射剂量的方法。方法:应用东芝500mA遥控X线机、FJ-427型热释光剂量仪等设备,对100名3~5岁儿童体检时,随机分成两个对照组、每组50名,分别接受胸透或平片检查,对检查测得数据均进行统计学处理。结果:胸透时胸部接受的照射剂量是平片的22倍多,其它部位接受的X线散射剂量平均值之比亦在20~30倍之间。结论:在儿童X线体检中应采用常规胸片替代胸透,可以有效地降低其辐射危害。     

歼击机飞行员改装体检脊柱病症的医学鉴定

目的对近几年来我院改装体检歼击机飞行员脊柱病症健康鉴定进行归纳总结。方法收集分析了261例歼击机飞行员体检和X线、CT的影像诊断资料,并对因脊柱病症体检不合格资料进行统计学分析。结果歼击机飞行员体检中,脊柱影像诊断中以腰椎间盘突出(49例)最多,但多数没有相应的临床症状,有20例因脊柱病症不合格,其中腰椎双侧峡部裂伴Ⅰ°滑脱9例,占不合格总数的45%,是不合格的主要原因。结论外科体检中应该重点加强对脊柱的检查,影像诊断应结合症状和脊柱功能作出鉴定,必要时应作随访观察。
