摘要:


文题释义:

全身振动:是一种利用振动平台(即振动装置)使人体全身暴露于振动中的方法。这种方法可以在改善身体功能、增强肌肉力量、预防跌倒、增加骨密度和肌肉耐力等方面发挥积极作用。
延迟性肌肉酸痛:是指在进行大强度或者采用一种新的运动形式运动后,导致的一种超微结构的肌肉损伤,继而引发疼痛、肌肉僵硬与肿胀以及功能下降等症状,这些症状在运动后的24 h内逐渐增加,在24-72 h之间达到顶峰,在5-7 d后逐渐消失。

背景:运动前使用全身振动能够减轻延迟性肌肉酸痛的程度,然而缺少何种振动频率效果更佳的文献报道。
目的:探讨在运动前使用50 Hz或35 Hz的全身振动对于普通男大学生运动后下肢股四头肌延迟性肌肉酸痛的影响。
方法:选择31名健康非体育专业男大学生,年龄(22.7±1.6)岁,随机分成50 Hz全身振动组(n=10)、35 Hz全身振动组(n=11)和对照组(n=10)。采用行进间全蹲跳和负重半蹲跳的方式诱导股四头肌延迟性肌肉酸痛,在运动前1 d、运动后即刻及运动后1,2,3,7 d测试肌肉疼痛目测类比评分和伸膝关节的等长峰值力矩;运动前1 d、运动后1,2,7 d测定血清肌酸激酶、白细胞介素6和前列腺素E2的表达水平。

结果与结论:①在运动后1,2,3 d,50 Hz全身振动组和35 Hz全身振动组的目测类比评分和等长峰值力矩下降值均低于对照组(P < 0.05);在运动后2 d,50 Hz全身振动组的目测类比评分低于35 Hz全身振动组(P < 0.05);在运动后2,3 d,50 Hz全身振动组的等长峰值力矩下降值低于35 Hz全身振动组(P < 0.05);②50 Hz全身振动组肌酸激酶水平在运动后1,2 d低于对照组(P < 0.05),35 Hz全身振动组在运动后2 d低于对照组(P < 0.05);③与运动前1 d相比,50 Hz全身振动组白细胞介素6水平各时间点无显著变化(P > 0.05);35 Hz全身振动组在运动后1 d显著增高(P < 0.05),对照组在运动后1,2 d显著增高(P < 0.05);④3组的前列腺素E2水平在运动后1 d均较运动前1 d显著增高(P < 0.05);⑤结果表明,运动前使用全身振动能够减轻运动后出现的延迟性肌肉酸痛和力量损失,同时对相关血液指标有一定的改善作用,使用50 Hz的全身振动比使用35 Hz效果更佳。

Abstract: BACKGROUND: Whole-body vibration may be used as a pre-exercise intervention to alleviate symptoms of delayed-onset muscular soreness. However, there is no report on which vibration frequency is more effective
OBJECTIVE: To investigate the effect of whole-body vibration at 50 Hz or 35 Hz before exercise on delayed-onset muscular soreness of the quadriceps muscle after exercise in general male college students.
METHODS: Thirty-one healthy non-athletic male college students, aged (22.7±1.6) years, were randomly divided into a 50 Hz whole-body vibration group (50 Hz-WBV group; n=10), a 35 Hz whole-body vibration group (35 Hz-WBV group; n=11), and a control group (n=10). Delayed-onset muscular soreness of the quadriceps muscle was induced by full squat jumps and weighted half squat jumps. Visual analogue scale score for muscle soreness and maximum voluntary isometric contraction muscle strength were measured 1 day before exercise, immediately after exercise, and 1, 2, 3 and 7 days after exercise. Serum creatine kinase, interleukin-6 and prostaglandin E2 levels were measured at all time points except immediately after exercise and 3 days after exercise.
RESULTS AND CONCLUSION: At 1, 2, and 3 days after exercise, visual analogue scale scores and peak torque values were lower in the 50 Hz-WBV group and 35 Hz-WBV group than the control group (P < 0.05). At 2 days after exercise, visual analogue scale scores were lower in the 50 Hz-WBV group than the 35 Hz-WBV group (P < 0.05); at 2 and 3 days after exercise, the reduction in peak torque values was lower in the 50 Hz-WBV group than the 35 Hz-WBV group (P < 
0.05). Serum creatine kinase levels were lower in the 50 Hz-WBV group than the control group at 1 and 2 days after exercise (P < 0.05), and the serum creatine kinase level in the 35 Hz- WBV group were lower than that in the control group at 2 days after exercise (P < 0.05). Interleukin-6 levels, compared with the baseline, were not statistically different at any time point in the 50 Hz-WBV group (P > 0.05), but were significantly higher in the 35 Hz-WBV group at 1 day after exercise (P < 0.05) as well as in the control group at 1 and 2 days after exercise (P < 0.05). Prostaglandin E2 levels were significantly higher in all the three groups at 1 day after exercise compared with the baseline (P < 0.05). These results suggest that the pre-exercise whole-body vibration alleviates delayed-onset muscular soreness and reduces strength loss that occur after exercise, as well as has a beneficial effect on related blood indicators. Moreover, whole-body vibration at 50 Hz is more effective than that at 35 Hz.

Key words: delayed-onset muscle soreness, whole-body vibration, frequency, pain, muscle strength, creatine kinase, serum interleukin-6, prostaglandin E2
