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, [Formula: see text]), sling therapy group with whole body vibration continuous (SAVG, [Formula: see text]) and sling therapy group with whole body vibration in intermittent (SIVG, [Formula: see text]) were randomly composed. Sling exercise therapy using supine position and whole-body vibration of 10[Formula: see text]Hz, 5[Formula: see text]mm 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 15[Formula: see text]min, 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/s 2 ) 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[Formula: see text]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.
