摘要
运动员在体力消耗时能快速准确地解读动态视觉场景。了解运动相关脑震荡(SRC)后体力消耗的增加会如何影响视力和认知能力非常重要。目的 研究跑步机跑步研究方案对近期有和没有 SRC 史的运动员的动态视敏度(DVA)和平衡评估的影响。方法 将近期有 SRC 史的校队运动员(CONC=12)与没有 SRC 史的运动员(ATHLETE=19)进行比较。DVA任务以30°/s的速度在随机行走(RW)或水平(H)运动过程中以四种可能的方向呈现翻滚 "E "目标。参与者在四个时间点站在力板上(1000Hz)进行 DVA 试验:1)运动前(PRE-EX);2)运动后立即(POST1);3)运动后 10 分钟(POST10);4)运动后 20 分钟(POST20)。成绩以 DVA 分数与 PRE-EX 相比的变化和中位反应时间(RT,毫秒)计算。结果 两组均保持了两种运动类型的 DVA 分值,并在 RT 上表现出运动引起的立竿见影的效果。两组在跑步机运动后的平衡控制策略变化相似。剧烈运动后的重复测量评估可为脑震荡后恢复运动的运动员提供有关视觉和神经认知功能的有意义的见解。
A treadmill running research protocol to assess dynamic visual acuity and balance for athletes with and without recent concussion history.
Athletes interpret dynamic visual scenes quickly and accurately during physical exertion. It is important to understand how increased exertion may impact vision and cognition following sport-related concussion (SRC).Purpose To examine the effect of a treadmill running research protocol on the assessment of dynamic visual acuity (DVA) and balance for athletes with and without recent history of SRC.Methods Varsity athletes following recent SRC (CONC=12) were compared to athletes without SRC (ATHLETE=19). The DVA task presented a Tumbling 'E' target in four possible orientations during random walk (RW) or horizontal (H) motion at a speed of 30°/s. Participants performed DVA trials standing on a force plate (1000Hz) at four time points: 1) pre-exercise (PRE-EX), 2) immediately (POST1), 3) 10-minutes (POST10), and 4) 20-minutes post- exercise (POST20). Performance was calculated as a change in DVA score from PRE-EX and median response time (RT, ms). Balance control was analyzed using the root mean square of centre of pressure displacement (dCOP).Results Both groups maintained DVA scores for both motion types and exhibited immediate exercise-induced benefits on RT. Both groups had similar change in balance control strategy following treadmill exercise.Conclusion Both groups elicited similar exercise-induced benefits on DVA following exercise. A repeated measures assessment following vigorous exercise may provide meaningful insights about visual and neurocognitive functions for athletes returning to sport following concussion.
