Abstract

García-Pinillos, F, Soto-Hermoso, VM, and Latorre-Román, PÁ. Do running kinematic characteristics change over a typical HIIT for endurance runners?. J Strength Cond Res 30(10): 2907-2917, 2016-The purpose of this study was to describe kinematic changes that occur during a common high-intensity intermittent training (HIIT) session for endurance runners. Twenty-eight male endurance runners participated in this study. A high-speed camera was used to measure sagittal-plane kinematics at the first and the last run during a HIIT (4 × 3 × 400 m). The dependent variables were spatial-temporal variables, joint angles during support and swing, and foot strike pattern. Physiological variables, rate of perceived exertion, and athletic performance were also recorded. No significant changes (p ≥ 0.05) in kinematic variables were found during the HIIT session. Two cluster analyses were performed, according to the average running pace-faster vs. slower, and according to exhaustion level reached-exhausted group vs. nonexhausted group (NEG). At first run, no significant differences were found between groups. As for the changes induced by the running protocol, significant differences (p ≤ 0.05) were found between faster and slower athletes at toe-off in θhip and θknee, whereas some changes were found in NEG in θhip during toe-off (+4.3°) and θknee at toe-off (-5.2°) during swing. The results show that a common HIIT session for endurance runners did not consistently or substantially perturb the running kinematics of trained male runners. Additionally, although some differences between groups have been found, neither athletic performance nor exhaustion level reached seems to be determinant in the kinematic response during a HIIT, at least for this group of moderately trained endurance runners.

摘要

加西亚 - 皮尼洛斯,F;索托 - 埃尔莫索,VM;拉托雷 - 罗曼,PÁ。耐力跑者在典型的高强度间歇训练中跑步运动学特征会发生变化吗?《力量与体能研究杂志》30(10): 2907 - 2917,2016年——本研究的目的是描述耐力跑者在常见的高强度间歇训练(HIIT)过程中发生的运动学变化。28名男性耐力跑者参与了本研究。使用高速摄像机在HIIT(4×3×400米)的第一次和最后一次跑步时测量矢状面运动学。因变量是时空变量、支撑期和摆动期的关节角度以及脚着地模式。还记录了生理变量、主观用力程度和运动表现。在HIIT期间,未发现运动学变量有显著变化(p≥0.05)。根据平均跑步速度(较快与较慢)以及达到的疲劳程度(疲劳组与非疲劳组,NEG)进行了两项聚类分析。在第一次跑步时,各组之间未发现显著差异。至于跑步方案引起的变化,较快和较慢的运动员在蹬离时髋关节角度(θhip)和膝关节角度(θknee)存在显著差异(p≤0.05),而在非疲劳组中,摆动期蹬离时髋关节角度(+4.3°)和膝关节角度(-5.2°)有一些变化。结果表明,耐力跑者的常见HIIT训练并未持续或显著干扰训练有素的男性跑者的跑步运动学。此外,尽管发现了组间的一些差异,但至少对于这组中等训练水平的耐力跑者来说,运动表现和达到的疲劳程度似乎都不是HIIT期间运动学反应的决定因素。
