摘要
轮椅击剑是一项中距离格斗运动,轮椅固定在地板上。这需要最大限度的注意力和酝酿速度。精炼的技术和疲劳耐受力对取得竞技成绩至关重要。目的:本研究的主要目的是测量精英轮椅击剑运动员在有疲劳和无疲劳状态下做出直接攻击手势的速度和肌肉参与度。方法对 10 名精英直接击剑运动员的最大等长力、手势速度和手势速度阻力进行了估计。结果结果显示,坐高和翼展是获得最高速度的重要因素,尤其是女性(r = 0.9; p = 0.07)。其他因素,如肘部角度(闭合位置更好),也影响了两类运动员的肌肉收缩(p = 0.01)。B 组的疲劳开始时间早于 A 组,直接攻击动作的变化更大。这些结果凸显了分析直接攻击以最佳应用快速力量、速度和肌肉参与的重要性,以及确定技术退化开始时间以制定竞争策略的重要性。这些参数可帮助精确设计轮椅射击精英的训练课程。
Muscle Changes during Direct Attack under Different Conditions in Elite Wheelchair Fencing
Wheelchair fencing is a medium-distance combat sport in which the wheelchair is fixed to the floor. This requires a maximum concentration and gestational speed. Refined techniques and fatigue tolerance are essential to achieve competitive results. Aim: The main objective of this study was to measure the speed and muscular participation of a direct attack gesture with and without fatigue in a sample of elite wheelchair fencers. Methods: The maximal isometric force, gestural speed, and resistance to gestural velocity were estimated in 10 elite performed direct fencers. Results: The results revealed that sitting height and wingspan were important factors in achieving the highest speed, especially in women (r = 0.9; p = 0.07). Other factors, such as the elbow angle where the closed position was better, affected muscle contraction in both categories of athletes (p = 0.01). The onset of fatigue was earlier in category B than in category A, with greater variation in direct attack movement. The results highlight the importance of analyzing direct attacks for the best application of quick force, speed, and muscle participation, as well as identifying the onset of technical deterioration to devise a competitive strategy. These parameters may allow for precise design of conditioning sessions for elite wheelchair shooters.
