REDUCING THE SPORTS INJURY THROUGH FUNCTION MOVEMENT BIOLOGICAL IMAGE DATA SCREENING

ABSTRACT Introduction Among the many cases of sports injuries, the incidence of musculoskeletal injuries remains high. After a musculoskeletal injury occurs, athletes often need to suspend training and undergo rehabilitation. A suitable sport mode requires athletes to have sufficient joint range of motion, core stability, and balance ability in different positions to complete various complex movements in training and competition. Objective The paper analyzes the impact of warm-up exercises before the test on the test results of functional sports biological image data screening ( FMS TM ) and provides references for unifying test conditions, checking the reliability of FMS TM repeated tests, and discussing the comparability of the research results. Methods The paper used the same password and process to test 12 young male volleyball professional athletes without warm-up and warm-up. The two-dimensional motion analysis system Dartfish Pursuit 8.0 was used to analyze the video data recorded by the two cameras simultaneously. Results In the two tests before and after, the hurdle step score (1.75±0.62 vs. 2.42±0.52) and the total score (13.50±2.20 vs. 16.42±2.15) were significantly higher than those without the warm-up test (P<0.01). Besides, in squats (1.58±0.67 vs. 1.92±0.67), straight lunges (2.00±0.43 vs. 2.50±0.52), active straight leg lifts (1.50±0.67 vs. 2.00±0.60), rotation stability (1.42) ±0.52 vs. 1.92±0.29) showed a significant increase in the score (P<0.05). Conclusions Warm-up exercises before the test can improve the test results. This abnormal movement pattern observed only by visual inspection may not truly reflect the “dysfunction” of the movement. In the case of ignoring the pre-test warm-up factors, feedback on sports performance and formulating training strategies, this conclusion of predicting injury risk and evaluating training effects may have specific limitations in its reference value.

摘要
引言：在各类运动损伤案例中，肌肉骨骼损伤的发生率始终居高不下。运动员发生肌肉骨骼损伤后，通常需暂停训练并接受康复治疗。高质量的运动表现要求运动员在不同体位下具备充足的关节活动度、核心稳定性与平衡能力，方能完成训练及赛事中的各类复杂动作。
研究目的：本研究旨在探讨测试前热身运动对功能性动作筛查（Functional Movement Screen, FMS™）测试结果的影响，为统一测试条件、验证FMS™重复测试信度以及探讨研究结果的可比性提供参考依据。
研究方法：本研究采用统一的测试流程与设置，对12名青年男子职业排球运动员分别开展无热身及有热身状态下的测试。采用二维运动分析系统Dartfish Pursuit 8.0，对两台同步摄像机录制的视频数据进行分析处理。
研究结果：相较于无热身测试的结果，热身状态下的跨栏步得分（1.75±0.62 vs. 2.42±0.52）与总得分（13.50±2.20 vs. 16.42±2.15）均显著升高，差异具有统计学意义（P<0.01）。此外，深蹲（1.58±0.67 vs. 1.92±0.67）、直线箭步蹲（2.00±0.43 vs. 2.50±0.52）、主动直腿抬高（1.50±0.67 vs. 2.00±0.60）及旋转稳定性（1.42±0.52 vs. 1.92±0.29）四项测试的得分均显著提升，差异具有统计学意义（P<0.05）。
研究结论：测试前进行热身运动可有效提升FMS™测试得分。仅通过目视观察发现的异常动作模式，或许无法真实反映动作的功能障碍状态。若在运动表现反馈与训练策略制定过程中忽略测试前热身因素，那么基于该结论开展损伤风险预测与训练效果评估，其参考价值将存在一定局限性。
