: The aim of this study was to test the hypothesis that vibration treatment reduces delayed-onset muscle soreness and swelling and enhances recovery of muscle function after eccentric exercise.
: A randomized crossover design was used. Fifteen young men performed ten sets of six maximal eccentric contractions of the elbow flexors with the right arm for one occasion and the left arm for the other occasion separated by 4 wks. One arm received a 30-min vibration treatment at 30 mins after and 1, 2, 3, and 4 days after the exercise (treatment group), and the other arm did not receive any treatment (control group). The order of the treatment and control conditions and the use of the dominant and nondominant arms were counterbalanced among subjects. Changes in indirect markers of muscle damage were compared between arms by a two-way repeated-measures analysis of variance.
: Compared with the control group, the treatment group showed significantly (P < 0.05) less development and faster reduction in delayed-onset muscle soreness at 2 to 5 days after exercise. The recovery of range of motion was significantly (P < 0.05) faster for the treatment than for the control group. However, no significant effects on the recovery of muscle strength and serum creatine kinase activity were evident. Immediately after the vibration treatment, a significant (P < 0.05) decrease in the magnitude of delayed-onset muscle soreness and muscle strength and an increase in pressure pain threshold and range of motion were found.
: These results showed that the vibration treatment was effective for attenuation of delayed-onset muscle soreness and recovery of range of motion after strenuous eccentric exercise but did not affect swelling, recovery of muscle strength, and serum creatine kinase activity.
本研究旨在验证振动治疗可减轻延迟性肌肉酸痛和肿胀，促进离心运动后肌肉功能恢复的假设。
采用随机交叉设计。15 名年轻男性在一次实验中使用右臂进行 10 组 6 次最大的肘屈肌离心收缩，在另一次实验中使用左臂进行同样的收缩，两次实验间隔 4 周。一只手臂在运动后 30 分钟以及 1、2、3、4 天接受 30 分钟的振动治疗（治疗组），另一只手臂不接受任何治疗（对照组）。治疗和对照条件的顺序以及使用优势和非优势手臂在受试者之间平衡。通过双向重复测量方差分析比较手臂间间接肌肉损伤标志物的变化。
与对照组相比，治疗组在运动后 2 至 5 天延迟性肌肉酸痛的发展明显减少（P < 0.05），且缓解速度更快。治疗组的关节活动度恢复明显快于对照组（P < 0.05）。然而，在肌肉力量和血清肌酸激酶活性的恢复方面，没有明显的影响。在振动治疗后立即，延迟性肌肉酸痛和肌肉力量的幅度明显下降（P < 0.05），同时压力疼痛阈值和关节活动度增加。
这些结果表明，振动治疗对于剧烈离心运动后延迟性肌肉酸痛的缓解和关节活动度的恢复是有效的，但对肿胀、肌肉力量和血清肌酸激酶活性的恢复没有影响。
