Exertional tests have become a promising tool to assist clinicians in the management of concussions, however require expensive equipment, extensive spaces, and specialized clinician expertise. As such, we developed a test with minimal resource requirements encompassing key elements of sport and physical activity. The purpose of this study was to pilot test the Multimodal Exertional Test (MET) protocol in a sample of healthy interuniversity athletes.
The MET comprises four stages, each featuring three distinct tasks. The test begins with engaging in squats, alternating reverse lunges, and hip hinges (). The next stage progressively evolves into executing these tasks within specified time limits (). Following this, the test advances to a stage that incorporates cognitive tasks (), and the final stage demands greater levels of physical exertion, cognition, and multi-directional movements (). Heart rate (HR) was obtained during each stage of the MET and participants' symptom severity scores were recorded following each task.
Fourteen healthy interuniversity athletes ( = 8 female, = 6 male) participated in the study. HR was obtained for 10 of the 14 athletes (females: = 6, males: = 4). Increases in average and maximum HR were identified between pre-MET and Stage 1, and between Stages 3 and 4. Consistent with the tasks in each stage, there were no increases in average and maximum HR observed between MET Stages 1 to 3. Female athletes exhibited higher average and maximum HRs compared to male athletes during all four stages. All 14 athletes reported minimal changes in symptom severity following each task.
Among healthy athletes, the MET elicits an increase in average and maximum HR throughout the protocol without symptom provocation. Female athletes exhibit higher HRs during all four stages in comparison to male athletes.
运动测试已成为协助临床医生管理脑震荡的一种有前景的工具，然而该测试需要昂贵的设备、宽敞的空间以及专业的临床医生专业知识。因此，我们开发了一种资源需求最少的测试，该测试涵盖了运动和体育活动的关键要素。本研究的目的是在一组健康的校际运动员样本中对多模式运动测试（MET）方案进行初步测试。
MET包括四个阶段，每个阶段有三个不同的任务。测试开始时进行深蹲、交替反向弓步和臀部铰链动作（）。下一阶段逐渐发展为在规定时间内执行这些任务（）。在此之后，测试进入包含认知任务的阶段（），最后阶段需要更高水平的体力消耗、认知和多方向运动（）。在MET的每个阶段获取心率（HR），并在每个任务后记录参与者的症状严重程度评分。
14名健康的校际运动员（8名女性 = ，6名男性 = ）参与了该研究。14名运动员中有10名获得了心率数据（女性：6名 = ，男性：4名 = ）。在MET前和第1阶段之间，以及第3阶段和第4阶段之间，平均心率和最大心率有所增加。与每个阶段的任务一致，在MET第1阶段到第3阶段之间，平均心率和最大心率没有增加。在所有四个阶段中，女性运动员的平均心率和最大心率均高于男性运动员。所有14名运动员在每个任务后报告症状严重程度变化极小。
在健康运动员中，MET在整个测试过程中会引起平均心率和最大心率增加，且不会引发症状。与男性运动员相比，女性运动员在所有四个阶段的心率都更高。
