This study aimed to verify the time course recovery of muscle edema within the quadriceps femoris and functional performance after lower-body single- and multi-joint exercises. For this within-participant unilateral and contralateral experimental design, fourteen untrained young males performed a unilateral knee extension exercise (KE), and a unilateral leg press (LP) exercise in a counterbalanced order. At pre-, post-, 24 h, 48 h, 72 h, and 96 h after exercise, the peak torque (PT), unilateral countermovement jump (uCMJ) performance, and rectus femoris (RF) and vastus lateralis (VL) muscle thicknesses were recorded in both legs. The PT decreased immediately after (p = 0.01) both exercises (KE and LP) and was fully recovered 24 h after KE (p = 0.38) and 48 h after LP (p = 0.68). Jump height and power, in the uCMJ, followed the same PT recovery pattern after both exercises. However, vertical stiffness (Kvert) was not affected at any time point after both protocols. The RF thickness increased after both exercises (p = 0.01) and was fully restored 48 h after KE (p = 0.86) and 96 h after LP (p = 1.00). The VL thickness increased after both exercises (p = 0.01) and was fully restored 24 h after LP (p = 1.00) and 48 h after KE (p = 1.00). The LP exercise, compared to KE, induced more prolonged impairment of functional performance and delayed recovery of RF muscle edema. However, the VL edema-induced muscle swelling recovery was delayed after the KE exercise. The different recovery kinetics between functional performance and muscle damage should be taken into consideration depending on the objectives of the next training sessions.
本研究旨在验证股四头肌内肌肉水肿的时间进程恢复情况以及下肢单关节和多关节运动后功能表现。对于这种受试者内单侧和对侧实验设计，14名未经训练的年轻男性以平衡顺序进行了单侧膝关节伸展运动（KE）和单侧腿举运动（LP）。在运动前、运动后、24小时、48小时、72小时和96小时，记录双腿的峰值扭矩（PT）、单侧反向移动跳跃（uCMJ）表现以及股直肌（RF）和股外侧肌（VL）的肌肉厚度。两种运动（KE和LP）后PT立即下降（p = 0.01），KE运动后24小时（p = 0.38）和LP运动后48小时（p = 0.68）完全恢复。两种运动后，uCMJ中的跳跃高度和功率遵循相同的PT恢复模式。然而，两种运动方案后的任何时间点垂直刚度（Kvert）均未受到影响。两种运动后RF厚度均增加（p = 0.01），KE运动后48小时（p = 0.86）和LP运动后96小时（p = 1.00）完全恢复。两种运动后VL厚度均增加（p = 0.01），LP运动后24小时（p = 1.00）和KE运动后48小时（p = 1.00）完全恢复。与KE相比，LP运动导致功能表现的损害更持久，RF肌肉水肿的恢复延迟。然而，KE运动后VL水肿引起的肌肉肿胀恢复延迟。根据下一次训练课程的目标，应考虑功能表现和肌肉损伤之间不同的恢复动力学。
