摘要： Objectives: To describe the patient, injury, assessment and treatment characteristics, as well as return-to-play timelines and clinical findings at discharge for adolescent patients after sport-related concussion. Design: Retrospective analysis of electronic medical records. Setting: Athletic training facilities of secondary school members of the Athletic Training Practice-Based Research Network (AT-PBRN). Patients: In total, 1886 patient records were reviewed. [1204 (63.8%) male, 682 (36.2%) female, age = 15.3 +/- 1.9 years, height = 169.5 +/- 13.5 cm, mass = 70.3 +/- 17.0 kg]. Patients were diagnosed with a concussion by an athletic trainer or team/directing physician. Interventions: None. Main Outcome Measures: Descriptive analysis of patient, injury, assessment, treatment, and participation status characteristics, as well as discharge information. Results: Injury demographic forms were completed for 1886 concussion cases. A concussion-specific evaluation form was completed for 55.9% (n = 1054) of cases. Treatment documentation was completed on 829 patients (44.0% of initial documented cases). Discharge forms were completed for 750 patients (40.0% of initial documented cases). Most cases were coded as 850.9-Concussion (85.5%, n = 642) and occurred during an in-season game (49.4%, n = 308). Time lost from competition was 24.9 +/- 39.9 days. Conclusions: Most concussion cases documented in this study were not on-field emergencies, as indicated by their normal clinical examinations and the lack of immediate referral to an emergency department. However, certain aspects of the clinical examination were often not assessed during the initial evaluation. These findings describe concussion assessment and recovery in adolescents and reinforce the need for a standardized approach to concussion assessment and appropriate documentation.

摘要： 体育教学活动的完善,离不开对教学素材和方式的完善。在研究体育活动完善的过程中,不少专家学者提出将传统茶文化与体育活动相结合,利用茶文化中所蕴含的文化底蕴和精神品质,在体育教学和运动训练过程中,丰富教学的素材和教学的方式,从而促进体育事业的发展。这具有一定的合理性。基于此,本文首先对传统茶文化进行了简单的概述,其次对茶文化与体育的渊源进行了分析,其中主要包括古代茶文化与体育、现代茶文化与体育两个方面;最后对传统茶文化应用于体育教育与运动训练的方法进行了探讨,其中主要包括以茶会友强体育、用茶提升体育修养、借茶丰富体育教学几个方面,希望能够通过简单的分析,可以为后研究者提供适当的借鉴参考意义。

摘要： Recent data demonstrate improved locomotion with high-intensity locomotor training (LT) in individuals with incomplete spinal cord injury (iSCI), although concerns remain regarding reinforcement of abnormal motor strategies. The present study evaluated the effects of LT intensity on kinematic and neuromuscular coordination in individuals with iSCI. Using a randomized, crossover design, participants with iSCI received up to 20 sessions of high-intensity LT, with attempts to achieve 70-85% of age-predicted maximum heart rate (HRmax), or low-intensity LT (50-65% HRmax), following which the other intervention was performed. Specific measures included spatiotemporal variables, sagittal-plane gait kinematics, and neuromuscular synergies from electromyographic (EMG) recordings. Correlation analyses were conducted to evaluate associations between variables. Significant improvements in sagittal-plane joint excursions and intralimb hip-knee coordination were observed following high- but not low-intensity LT when comparing peak treadmill (TM) speed before and after LT. Neuromuscular complexity (i.e., number of synergies to explain >90% of EMG variance) was also increased following high- but not low-intensity LT. Comparison of speed-matched trials confirmed significant improvements in the knee excursion of the less impaired limb and intralimb hip-knee coordination, as well as improvements in neuromuscular complexity following high-intensity LT. These findings suggest greater neuromuscular complexity may be due to LT and not necessarily differences in speeds. Only selected kinematic changes (i.e., weak hip excursion) was correlated to improvements in treadmill speed. In conclusion, LT intensity can facilitate gains in kinematic variables and neuromuscular synergies in individuals with iSCI.

摘要： The multidimensional concept of creativity has a much wider scope of application than disclosed by prevailing research on sporting creativity. In this area, creativity is mostly perceived, praised, and approached for its performative, in-game benefits. Pointing to the belief that creativity requires well-developed technical skills, this phenomenon is often treated as a performative end. When targeting creative match performances, the developmental and experiential benefits of creative activities may be neglected, and creativity may be reserved for the best offensive players. To nourish and nuance practical and scholastic dialogues, the purpose of this paper is to conceptualize creativity as a developmental resource in sport training activities. This is accomplished by building on and articulating [Shilling, C. (2005). Body in culture, technology and society. London: SAGE] body-sociology, [Glaveanu, V. P. (2012).

Based on these positions, creativity is treated as a dynamic quality of action that is located in the transaction between the player and the specific situation (i.e. affordances, intentions, and norms). Hence, creativity regards the exploratory and playful processes of discovering, exploiting, and originating unusual action possibilities (i.e. acting on unperceived, unexploited, and uninvented affordances). Grounded in these ideas, we argue for the stimulati

摘要： 目的:研究肺康复运动训练在肺癌肺叶切除术患者护理中的应用疗效。方法:选择我院2017年2月至2018年3月胸外科肺叶切除的患者42例,并以护理方式不同随机分为对照组与观察组,各21例。观察患者术后并发症发生率及术后一个月的FVC、FEVI及MVV指标。结果:观察组术后并发症发生率9.52%明显优于常规组38.1%(P<0.05)。术后一个月FVC、FEVI及MVV指标观察组各项指标均优于常规组(P<0.05)。结论:肺癌肺叶切除术后进行肺康复训练有良好的临床价值。
