研究目的：

本研究以疲劳状态下下肢缓冲性能的动态变化为切入点，比较低功率自行车骑行、泡沫轴滚压和静息休息三种常见恢复方式的干预效果。通过在疲劳后不同时间点连续跟踪下肢缓冲动作的技术特征与冲击调节模式，系统分析各恢复策略在缓冲动作质量维持、冲击负荷控制及恢复进程加速等方面的差异，探讨不同恢复方式对下肢缓冲机制重建的作用特点与调节路径，旨在阐明恢复方式与落地缓冲功能之间的关系，为疲劳管理和下肢损伤预防策略的制定提供可操作的参考依据。  

Objectives of Study：

This study focuses on the dynamic changes in lower-limb cushioning performance under fatigue and compares the effects of three common recovery methods: low-intensity cycling, foam rolling, and passive rest. By continuously tracking the technical characteristics and impact-regulation patterns of lower-limb cushioning movements at different time points after fatigue, this study systematically analyzes the differences among these recovery strategies in maintaining cushioning movement quality, controlling impact loads, and accelerating the recovery process. It further explores the specific roles and regulatory pathways of different recovery methods in reconstructing lower-limb cushioning mechanisms. The aim is to clarify the relationship between recovery methods and landing-cushioning function, and to provide practical evidence for the development of fatigue management and lower-limb injury prevention strategies.

药物成份或治疗方案详述：

本实验所有流程均在广州体育学院体能中心完成。每名受试者在不同恢复条件下共进行3次运动生物力学测试，每次测试间隔至少48 h，并要求在每次实验前24 h内避免剧烈运动。 具体流程如下：受试者到达实验室后填写基本信息表，由研究助理说明实验流程及注意事项，自愿参加者签署知情同意书。随后静坐5 min并采集静息心率，以确认实验前未进行高强度体力活动。之后，受试者更换统一运动鞋和实验服装，佩戴心率带并贴附反光标记点（见表1），完成自主拉伸及3 min跑台热身（12 km/h），同时进行数据预采集与设备同步。 热身结束后拍摄静态模型，随后进行前测。受试者从距测力台20 cm处放置的30 cm跳箱上自然下落，完成标准化落地缓冲任务。动作要求为：受试者站立于跳箱上，主导腿向前迈出并带动身体自然下落，支撑腿随后离台；落地时双脚同时着地，分别落于对应测力板；随后双膝屈曲完成自然缓冲，下蹲至舒适最低点后缓慢恢复至接近直立，并稳定站立3 s。每名受试者每个动作采集3次有效数据，有效测试定义为动作按要求完成且数据采集完整。 前测结束后立即实施递增疲劳诱导方案，达到疲劳标准后即刻进行后测。后测动作与前测一致，测试时间点为恢复后即刻、15 min和30 min。确认数据采集无误后结束本次实验。至少间隔48 h后进行下一次测试，并更换不同恢复手段。所有受试者完成3种恢复条件下的全部测试后，实验结束 

Description for medicine or protocol of treatment in detail：

All experimental procedures were conducted at the Strength and Conditioning Center of Guangzhou Sport University. Each participant completed three biomechanical testing sessions under three different recovery conditions. The interval between sessions was at least 48 h, and participants were instructed to avoid strenuous exercise within 24 h before each trial. The experimental procedure was as follows. Upon arrival at the laboratory, participants completed a basic information form. A research assistant then explained the experimental procedures and precautions, after which all volunteers signed an informed consent form. Participants subsequently remained seated for 5 min, during which resting heart rate was recorded to confirm that no high-intensity physical activity had been performed before testing. Participants then changed into standardized athletic shoes and experimental clothing, wore a heart rate monitor, and had reflective markers attached (Table 1). This was followed by self-directed stretching and a 3 min treadmill warm-up at 12 km/h, during which preliminary data acquisition and equipment synchronization were completed. After the warm-up, a static model was captured, followed by the pre-test. Participants performed a standardized landing-cushioning task by stepping off a 30 cm box placed 20 cm from the force platforms. Specifically, participants stood steadily on the box, stepped forward with the dominant leg to initiate a natural descent, and then brought the support leg off the box. Upon landing, both feet contacted the ground simultaneously, with each foot landing on its designated force plate. Participants then flexed both knees to perform natural cushioning, squatted to a self-selected lowest comfortable position, and gradually returned to a near-upright posture, maintaining a stable standing position on the force plates for 3 s. Three valid trials were collected for each movement. A valid trial was defined as one in which the participant completed the movement as instructed and the data were fully recorded. Immediately after the pre-test, an incremental fatigue-induction protocol was implemented. Once the fatigue criterion was reached, the post-test was conducted immediately. The post-test movement was identical to that of the pre-test, and measurements were obtained at three time points: immediately after recovery, 15 min after recovery, and 30 min after recovery. After confirming that the data had been collected correctly, the session ended. The next testing session was conducted at least 48 h later under a different recovery condition. The experiment concluded after all participants completed testing under all three recovery conditions.

干预措施：

为了在每名受试者内比较不同恢复方式的效果，每名受试者将进行三次独立的疲劳诱导与恢复干预（恢复方式不同），两次测试间至少间隔48小时，测试顺序随机分配且不同受试者间平衡各恢复条件。受试者在每次测试中随机接受其中一种疲劳恢复条件（A：静息休息；B：低功率骑行；C：泡沫轴滚压放松）。

干预措施代码：

Intervention：

To compare the effects of different recovery methods within each participant, each participant completed three independent fatigue-induction and recovery-intervention sessions, each involving a different recovery condition. A minimum interval of 48 h was maintained between any two sessions. The testing order was randomly assigned, and the recovery conditions were counterbalanced across participants. In each session, participants were randomly assigned to one of the following recovery conditions: (A) passive rest; (B) low-intensity cycling; or (C) foam rolling.

随机方法（请说明由何人用什么方法产生随机序列）：

本研究采用三处理、三周期随机交叉设计。为控制顺序效应及首阶携带效应，采用 Williams 设计平衡处理顺序，受试者随机分配至 6 个序列：ABC、ACB、BAC、BCA、CAB、CBA（A = 静息休息，B = 低功率骑行，C = 泡沫轴滚压）。每名受试者在 3 次独立测试中依次接受 3 种恢复干预，各测试间隔至少 48 h 作为洗脱期。随机序列由独立统计人员采用 R 软件预先生成，并由非研究实施人员加密保存，以保证分配隐藏。

Randomization Procedure (please state who generates the random number sequence and by what method)：

This study adopted a three-treatment, three-period randomized crossover design. To control for order effects and first-order carryover effects, a Williams design was used to balance the treatment sequences. Participants were randomly assigned to one of six sequences: ABC, ACB, BAC, BCA, CAB, and CBA (A = passive rest, B = low-intensity cycling, C = foam rolling). Each participant completed three independent testing sessions and received all three recovery interventions in sequence, with an interval of at least 48 h between sessions as the washout period. The randomization sequence was generated in advance by an independent statistician using R software and securely stored by personnel not involved in the study implementation to ensure allocation concealment.
