Abstract Research with cyclists suggests a decreased load on the lower limbs by placing the shoe cleat more posteriorly, which may benefit subsequent running in a triathlon. This study investigated the effect of shoe cleat position during cycling on subsequent running. Following bike-run training sessions with both aft and traditional cleat positions, 13 well-trained triathletes completed a 30?min simulated draft-legal triathlon cycling leg, followed by a maximal 5?km run on two occasions, once with aft-placed and once with traditionally placed cleats. Oxygen consumption, breath frequency, heart rate, cadence and power output were measured during cycling, while heart rate, contact time, 200?m lap time and total time were measured during running. Cardiovascular measures did not differ between aft and traditional cleat placement during the cycling protocol. The 5?km run time was similar for aft and traditional cleat placement, at 1084?±?80?s and 1072?±?64?s, respectively, as was contact time during km 1 and 5, and heart rate and running speed for km 5 for the two cleat positions. Running speed during km 1 was 2.1%?±?1.8 faster (P?<?0.05) for the traditional cleat placement. There are no beneficial effects of an aft cleat position on subsequent running in a short distance triathlon. 相似文献

蒙古族传统体育的演进与思考 总被引：4，自引：1，他引：3
内蒙古自治区成立后,蒙古族传统体育从“那达慕”的整体演进到各项目的具体发展都为我们提供了丰富的成功经验,当然,也存在一些值得思考的问题。“外之既不后于世界之思潮,内之仍弗失固有之血脉”是我们发展民族文化（包括民族体育）应遵循的原则 相似文献

本研究借鉴运动训练领域的经典理论“项群训练理论”对校园铁人三项运动的专项特征与实践训练进行深入探讨,为进一步发展校园铁人三项的科学训练提供理论依据。研究表明:校园铁三运动在竞技能力的长期训练导向上需实现“子项能力为基础,综合实力为导向,系统整合为目标”的整合化培育标准;在竞技能力发展内容上应遵循“体能为主导,技能是关键,心智作保障”的发展原则;在运动训练的组织方法上应满足“以有序的分项交替训练防疲劳,以科学的多项组合训练促提升”的可持续化发展要求。 相似文献

Various publications discuss the discrepancies of running in triathlons and stand-alone runs. However, those methods, such as analysing step-characteristics or ground-contact time, lack the ability to quantitatively discriminate between subtle running differences. The attractor method can be applied to overcome those shortcomings. The purpose was to detect differences in athletes’ running patterns (δM) and movement precision (δD) by comparing a 5,000 m run after a prior cycling session (TRun) with an isolated run over the same distance (IRun). Participants completed the conditions on a track and a stationary trainer, allowing the use of their personal bike to simulate an Olympic triathlon. During each run, three-dimensional acceleration data, using sensors attached to the ankles, were collected. Results showed that both conditions lead to elevated attractor parameters (δM and δD) over the initial five minutes before the athletes found their rhythm. This generates a new perspective because independent of running after a bike session or without preload, an athlete needs certain time to adjust to the running movement. Coaches must consider this factor as another tool to fine-tune pacing and performance. Moreover, the attractor method is a novel approach to gain deeper insight into human cyclic motions in athletic contexts. 相似文献

方法:运用文献资料法、数理统计法、实验法等,以我国女子铁人三项运动员为研究对象,对高原训练期间的训练负荷进行研究。结果:训练负荷量与训练周期成反比,铁人三项中各单项训练量从大到小的顺序依次为自行车、跑步和游泳;在训练强度上,是有氧训练为主,混氧训练为辅;高原训练的效果与训练负荷、训练周期相关,但是与训练周期不完全相关。结论:1)适当缩短高原训练周期,提高有效负荷训练;2)根据运动员的具体情况,合理安排铁人三项中各单项的训练负荷;3)在训练负荷量较小的前提下,加大重点课次的训练负荷强度,加深对机体的刺激深度,从而提高训练效果。 相似文献

In this study, we examined the consequences of a global alteration in running technique on running kinematics and running economy in triathletes. Sixteen sub-elite triathletes were pre and post tested for running economy and running kinematics at 215 and 250?m?·?min?1. The members of the treatment group (n = 8) were exposed to 12 weeks of instruction in the “pose method” of running, while the members of the control group (n = 8) maintained their usual running technique. After the treatment period, the experimental group demonstrated a significant decrease in mean stride length (from 137.25?±?7.63?cm to 129.19?±?7.43?cm; P <?0.05), a post-treatment difference in vertical oscillation compared with the control group (6.92?±?1.00 vs. 8.44?±?1.00?cm; P <?0.05) and a mean increase in submaximal absolute oxygen cost (from 3.28?±?0.36?l?·?min?1 to 3.53?±?0.43?l?·?min?1; P <?0.01). The control group exhibited no significant changes in either running kinematics or oxygen cost. The global change in running mechanics associated with 12 weeks of instruction in the pose method resulted in a decrease in stride length, a reduced vertical oscillation in comparison with the control group and a decrease of running economy in triathletes. 相似文献
