The purpose of this study was to investigate an effective recovery method on muscle function and blood of lactate level after maximal isotonic exercise. This study was conducted in 36 adult males. The group was divided into three groups. Sling therapy group (SG, n=12), sling therapy group with whole body vibration continuous (SAVG, n=12) and sling therapy group with whole body vibration in intermittent (SIVG, n=12) were randomly composed. Sling exercise therapy using supine position and whole-body vibration of 10Hz, 5mm were performed. Lactate level and muscle function during the rest, fatigue and recovery period were measured and then maximal exercise using back extension was performed to induce fatigue. After 15min, sling with whole body vibration was conducted in two groups, respectively. Blood lactate was measured a few hours before and after of vibration. Also, muscle function between only sling exercise therapy condition, sling with whole body vibration condition in all time and sling with whole body vibration condition in intermittent time were analyzed. Lactate level was recorded by lactate measurement device. Isokinetic of lumber joint extension and flexion Peak torque/body weight, total work (J), average power (W) and acceleration time (m/s²) were measured using isokinetic dynamometer. The recovery method of sling with whole body vibration showed positive changes in physical characteristics. Isokinetic contraction of peak torque/body weight (N⋅m), average power (Watts) and total work (J) were significantly increased in the recovery step for SIVG. Lactate level was significantly decreased for SIVG as compared with SG and SAVG. This study demonstrated that sling exercise therapy with intermittent time whole body vibration could provide a positive effect on the efficient recovery of muscle function and higher reduction of lactate after maximal isotonic exercise.

全身振动静息肌肉功能和乳酸血对吊带运动恢复的急性影响

本研究的目的是探讨最大等张运动后肌肉功能和血乳酸水平的有效恢复方法。这项研究是在 36 名成年男性中进行的。该组被分为三组。吊索治疗组（SG，n=12), 全身振动连续吊带治疗组 (SAVG,n=12) 和间歇性全身振动悬吊疗法组 (SIVG,n=12) 是随机组成的。吊带运动疗法采用仰卧位和全身振动10赫兹，5毫米进行了。测量休息、疲劳和恢复期间的乳酸水平和肌肉功能，然后使用背部伸展进行最大运动以诱导疲劳。15岁以后min，两组分别进行全身振动吊索。在振动前后数小时测量血乳酸。此外，还分析了单纯吊索运动治疗条件、全程全身振动条件吊索和间歇时间全身振动条件吊索之间的肌肉功能。乳酸水平由乳酸测量装置记录。腰关节伸展和屈曲的等速 峰值扭矩/体重、总功 (J)、平均功率 (W) 和加速时间 (m/s ² ) 使用等速测力计测量。全身振动吊索的恢复方法在物理特性上表现出积极的变化。峰值扭矩/体重的等速收缩（N⋅m)、平均功率 (Watts) 和总功 (J) 在 SIVG 的恢复步骤中显着增加。与 SG 和 SAVG 相比，SIVG 的乳酸水平显着降低。这项研究表明，间歇性全身振动的吊带运动疗法可以对肌肉功能的有效恢复和最大等张运动后乳酸的更高降低产生积极影响。
