檀志宗  楼俊华  李男 《体育科研》2019,(6):93-97

采用问卷调查法对浙沪两省市194名游泳运动员进行运动性伤病调查，主要从运动性伤病的类型、部位、性质方面对比分析不同竞技水平游泳运动员的伤病表型特征。结果显示：优秀运动员运动性损伤较常见，多以慢性劳损为主，损伤部位依次为肩关节、腰背部和膝关节；一般运动员常发生急性损伤，损伤部位依次为膝关节、肩关节和腰背部。两组运动员鼻炎和中耳炎均常见。因此，依据运动性伤病的可能原因与机制，需要制定有针对性的预防措施，以减少运动性伤病的发生。  相似文献

Changes in kinematics and arm–leg coordination during a 100-m breaststroke swim     

Samuel W. Oxford  Rob S. James  Michael J. Price  Carl J. Payton  Michael J. Duncan 《Journal of sports sciences》2017,35(16):1658-1665

The purpose of this study was to compare arm–leg coordination and kinematics during 100 m breaststroke in 26 (8 female; 18 male) specialist breaststroke swimmers. Laps were recorded using three 50-Hz underwater cameras. Heart rate and blood lactate were measured pre- and post-swim. Arm–leg coordination was defined using coordination phases describing continuity between recovery and propulsive phases of upper and lower limbs: coordination phase 1 (time between end of leg kick and start of the arm pull phases); and coordination phase 2 (time between end of arm pull and start of leg kick phases). Duration of stroke phases, coordination phases, swim velocity, stroke length (SL), stroke rate (SR) and stroke index (SI) were analysed during the last three strokes of each lap that were unaffected by turning or finishing. Significant changes in velocity, SI and SL (P < 0.05) were found between laps. Both sexes showed significant increase (P < 0.05) in heart rate and blood lactate pre- to post-swim. Males had significantly (P < 0.01) faster swim velocities resulting from longer SLs (P = 0.016) with no difference in SR (P = 0.064). Sex differences in kinematic parameters can be explained by anthropometric differences providing males with increased propelling efficiency.  相似文献

少儿初学者的新型游泳背漂的设计与应用          下载免费PDF全文

姜欣  陆阿明  王红金 《体育科研》2016,(6):97-100

针对现有背漂舒适度差、阻力大、易上滑的缺点,意在改良和设计一款新型背漂--鳍翼。采用观察法、问卷调查法、实验法,运用流体力学、运动生物力学原理,对新型背漂进行调查和实验研究。调查结果显示,与现有背漂相比,新型背漂舒适度良好。实验结果显示,与现有背漂相比,新型背漂出现系带滑落的次数、背漂上滑距离明显较少（P＜0.05）,且在25 m蛙泳腿测试中,实验组佩戴新型背漂的25 m蛙泳腿游进速度比对照组佩戴原有背漂的游进速度快,并存在显著性差异（P＜0.05）。研究结果表明新型背漂比原有背漂的阻力小,结构更优化,有利于学员更快、更安全地学习游泳,也有利于提高教练的教学效果。  相似文献

First-rib stress fracture in two adolescent swimmers: a case report     

Sara Low  Michael Kern 《Journal of sports sciences》2016,34(13):1266-1270

First-rib stress fractures have been described in adolescent athletes in various sports, with only one prior case report of first-rib stress fractures in an adolescent female swimmer. There is a need for research on the cause, management, and prevention of these injuries as they lead to significant morbidity and critical time away from sport for these aspiring athletes. We aimed to describe first-rib stress fractures as a potential cause for non-specific atraumatic chronic shoulder pain in adolescent swimmers and to discuss the different presentations, unique risk factors, treatment, and potential injury prevention strategies of such fractures. We discussed two such cases which were successfully treated with activity modification with restriction of all overhead activity, gradually progressive physical therapy and a return to swimming protocol. First-rib stress fractures can vary in presentation and should be in the differential diagnosis in adolescent swimmers with chronic shoulder pain. These injuries can be successfully managed with rest from overhead activities and physical therapy. Gradual return to competitive swimming can be achieved even with non-union of a first-rib stress fracture. Emphasis on balanced strength training in different muscle groups and proper swimming technique is essential to prevent these injuries.  相似文献   

The History of the South East Asian Peninsular Games,1959–1975     

Peng Han Lim  Mohd Salleh Aman 《国际体育史杂志》2016,33(5):545-568

After the Second World War the Southeast Asian countries of Burma (1948), Laos (1954), Cambodia (1955), South Vietnam (1955), Malaya (1957), and Singapore (1959) sought independence from the British, French and Japanese colonialists. The first post Second World War and post-colonial biannual multisport Southeast Asian Games was held in Bangkok in 1959 among these countries (and Thailand) although they were relatively poor developing countries. Referring to official reports of the eight bi-annual SEAP Games and other sources of information this research studies how the organization of the eight SEAP Games since 1959 contributed to the nation building process of each country and shaped the political landscape. This was carried out by creating a national identity through sports in each country as well as creating a sense of regional cooperation during periods of war, shifting boundaries and identities. This was done through rituals to legitimize newly ascended constitutional monarchies and heads of states, national flags and athletes' national identity during competition. The SEAP Games also gradually opened avenues for women's participation similar to female athletes in the Olympic Games. It also provided opportunities for promising athletes to shine, improve and compete at higher levels at the Asian and Olympic Games.  相似文献
