角特征当短跑运动员行进间起跑超过20米时,我们录制了每名运动员冲刺跑的一个单步技术,随后采用“Computrainer 2000”系统对运动员身体各环节通过该单步不同阶段(着地,缓冲,蹬伸,腾空)的角位移进行了计算。通过比较速度较快与速度较慢的短跑运动员的技术细节,我们发现了在跑步动作过程中腿和臂环节角位移的一些差异。我们在四个阶段对跑步动作进行了研
When the sprinter started to run more than 20 meters, we recorded a single-step technique for each athlete sprinting and then adopted the “Computrainer 2000” system for each step of the athlete’s body through different stages of the single step (landing, cushioning, Kicking, vacating) the angular displacement of the calculated. By comparing the technical details of the faster and slower sprinters, we found some differences in the angular displacement of the leg and arm joints during the running maneuver. We studied running in four stages
