采用文献资料、专家访谈,针对刘翔受伤及术后复出进行训练学分析。110 m栏项目技术特点和频繁的带伤参赛以及缺乏主动的恢复与调整是刘翔受伤的主要因素。跟腱伤术后积极主动恢复调整与科学训练让刘翔再次回到比赛跑道,并以"七步上栏"技术跑出12.87 s的2012年迄今世界最好成绩。从运动训练学视角对刘翔受伤、术后主动恢复调整与革命性的技术改进进行训练学分析,以期为我国这一运动项目更科学的训练提供参考。 相似文献

刘翔110 m栏第五栏中腾空过栏技术的运动学分析 总被引：6，自引：0，他引：6
对我国优秀男子110m栏运动员刘翔等人第五栏腾空过栏的技术动作分三次进行定点、定焦距、高速拍摄,采用影片数字化、数据平滑处理和运动生物力学计算机辅助解析和辅助教学系统软件解析以及体育统计等方法,通过分析刘翔等人第五栏腾空过栏技术的两维图像,运用生物力学理论将解析出的刘翔两次比赛的阶段性参数相比较,并与三次拍摄的其他可解析运动员的技术参数对比。解析结果表明:(1)刘翔两次比赛第五栏中腾空过栏时的躯干前倾性大,两腿最大夹角大,腾空时间短,腾空过栏的速度快。(2)刘翔两次比赛第五栏的跨栏步步长小,起跨攻栏距离与下栏着地距离之比非常接近理论上的最理想比例。 相似文献

对国家帆船队男子激光级两名重点运动员的研究发现,施某主要存在核心力量及高强度运动下腿部肌肉耐力不足,而乔某主要是由于腰肌劳损导致在进行高强度运动时出现腰部酸痛、僵硬、腰椎活动度减弱等问题。根据两者的不同状况,针对性的制定各自的训练方案,通过3~4周的训练后,运动员的运动能力及损伤恢复情况均有所改善。通过高水平运动员体能训练计划制定、实施,改善运动员的运动能力,完善有效提高帆船运动员专项体能训练的手段与方法。同时,通过对重点运动员损伤后的康复训练,汲取康复体能训练有效手段,探索运动损伤机制并在训练中积极预防损伤。 相似文献

AbstractThe purpose of this study was to examine the changes in the metabolic state of quadriceps femoris muscles using transverse relaxation time (T2), measured by muscle functional magnetic resonance (MR) imaging, after inactive or active recovery exercises with different intensities following high-intensity knee-extension exercise. Eight healthy men performed recovery sessions with four different conditions for 20 min after high-intensity knee-extension exercise on separate days. During the recovery session, the participants conducted a light cycle exercise for 20 min using a cycle (50%, 70% and 100% of the lactate threshold (LT), respectively: active recovery), and inactive recovery. The MR images of quadriceps femoris muscles were taken before the trial and after the recovery session every 30 min for 120 min. The percentage changes in T2 for the rectus femoris and vastus medialis muscles after the recovery session in 50%LT and 70%LT were significantly lower than those in either inactive recovery or 100%LT. There were no significant differences in those for vastus lateralis and vastus intermedius muscles among the four trials. The percentage changes in T2 of rectus femoris and vastus medialis muscles after the recovery session in 50%LT and 70%LT decreased to the values before the trial faster than those in either inactive recovery or 100%LT. Those of vastus lateralis and vastus intermedius muscles after the recovery session in 50%LT and 70%LT decreased to the values before the trial faster than those in 100%LT. Although the changes in T2 after active recovery exercises were not uniform in exercised muscles, the results of this study suggest that active recovery exercise with the intensities below LT are more effective to recover the metabolic state of quadriceps femoris muscles after intense exercise than with either intensity at LT or inactive recovery. 相似文献

Abstract Athletes often use contrast-water therapy as a recovery modality to reduce training fatigue. However, there is debate regarding the effectiveness of this practice, particularly when active and passive recovery regimens are more readily accessible. Fourteen male state-level hockey players participated in three experimental sessions involving two 30-s maximal-intensity Wingate ergometer tests interspersed by a 12-min recovery period. Three different recovery protocols were assessed. Passive recovery involved sitting while active recovery comprised low-intensity cycling. Contrast-water therapy recovery involved three cycles of alternate immersion in heated (38°C) and cool (15°C) water for 3.5 min and 30 s respectively. Heart rate, blood lactate concentration, and ratings of fatigue were assessed immediately before (baseline) and after the first Wingate test, 3 min and 7 min into and at the end of the recovery period, and immediately after the second Wingate test. Blood pressure was assessed at baseline, immediately before recovery, and immediately after recovery. Heart rate remained elevated 3 min and 7 min into as well as after active recovery compared with both contrast-water therapy (P<0.001) and passive recovery (P<0.001), and was elevated 3 min into and after contrast-water therapy recovery compared with passive recovery (P<0.001). Blood lactate concentration was significantly lowered 7 min into and after active recovery (P<0.001) and contrast-water therapy (P<0.001) compared with passive recovery, but no significant difference was observed between active recovery and contrast-water therapy. Rating of fatigue was significantly lower for contrast-water therapy (P<0.001) compared with passive recovery and active recovery, the latter two being similar. However, no significant differences were found between the recovery modalities for any of the test or retest Wingate performance indices. Although contrast-water therapy offered similar benefits to well-established active recovery protocols, it also resulted in reduced ratings of fatigue and a faster return to baseline for some variables. Although restricted to a limited time frame, these findings reflect that the subtle effects from contrast-water therapy may translate to important practical differences that can influence the recovery choices of athletes, particularly when engaged in intense events/training where the recovery period is limited. 相似文献

本文旨在为摸索髌骨骨折保守治疗的康复训练提供思维方法和实践体会。郑裕蒿在髌骨骨折后,通过10周的康复训练,恢复后1个月获得全国第十届运动会武术男子散打77.5kg级别的决赛权并在随后的决赛中荣获冠军。10周康复训练中主要采用肌力练习、关节活动度练习、耐力训练、神经肌肉本体感觉训练等一系列运动疗法,阶段性进行运动功能评定,制定一系列康复训练阶段性目标及预案。结果认为,骨折的康复训练计划以医学检查(临床表现、影像学诊断)、物理及传统治疗方法为前提,依据运动专项特点,制定阶段性个体化运动处方,会有效缩短伤病恢复时间。 相似文献

Abstract Six female collegiate swimmers were used to evaluate the hypothesis that the recovery procedure after exercise will not only affect subsequent performance, but will also affect the recovery process after the subsequent performance. Each swimmer exercised for two minutes at 90% [Vdot]O2 max on a swimming ergometer, recovered for 15 minutes by walking on land or swimming, then swam 200 yds. for time. Oxygen uptake was measured for 15 minutes after the 200 yd. swim. Venous blood, obtained after the ergometry swim, and before and after the 200 yd. swim, was analyzed for lactate. Two hundred yard swim times were not significantly affected by either the walking or swimming recovery procedures. Blood lactate after the ergometry swim averaged 96.7 ± 18 mg/100 ml. The swimming recovery reduced the lactate levels by 53.3% compared to a 38.5% reduction during the walking recovery. Significant differences in blood lactate were also noted after the 200 yd. swim, with the trials in which swimming recovery protocol was used yielding less than the trials involving the walking recovery (99 ± 8 mg/100 ml compared to 113 ± 8 mg/100 ml, respectively). The post 200 yd. swim oxygen uptakes averaged 7.74 ± 1.51 liters and were not affected by protocol. It was concluded that a 15 minute recovery period may be sufficient for repeated bouts of high intensity work lasting less than three minutes. It was also concluded that self-selection of the mode of recovery is not always the most effective for removal of blood lactate. 相似文献

Malcohn Tozer was appointed the founding headmaster of Northamptonshire Grammar School in 1989 after a 23 year career at Uppingham School. There his one claim to cricketing fame was to run tlie rival sport of atliletics, thus provoking his house regularly to win cricket competitions and to produce the school's two most recent Test players. One of his recreations is research in the overlapping histories of education, sport and imperialism for the Victonan and Edwardian eras, and he has published his findings in a series of papers and essays. 相似文献
