实验的结论是：一个针对颈部屈肌群的耐力力量运动方法能够有效的减少颈浅屈肌疲劳的肌电表现并增加有慢性非重度颈痛的一组受试者的颈椎曲屈强度。

那么下面则是这个实验的论文，喜欢干货的朋友们快来围观！！！

An endurance~strength training regime is effective in reducing myoelectric manifestations of cervical flexor muscle fatigue in females with chronic neck pain

耐力力量训练法能有效减轻女性慢性颈痛患者颈屈肌疲劳的肌电表现

OBJECTIVEThe purpose of this study was to investigate whether an endurance~strength training program is effective in reducing myoelectric manifestations of sternocleidomastoid (SCM) and anterior scalene (AS) muscle fatigue which have been found to be greater in people with chronic neck pain.

目标：这项研究的目的是耐力力量训练计划是否能够有效的减少颈部疼痛患者所具有的胸锁乳突肌的肌电表现（SCM）和前斜角肌肉疲劳。

METHODS:Fifty~eight female patients with chronic non~severe neck pain were randomized into one of two 6~week exercise intervention groups: an endurance~strength training regime for the cervical flexor muscles or a referent exercise intervention involving low load retraining of the cranio~cervical flexor muscles. The primary outcomes were a change in maximum voluntary contraction (MVC) force and change of the initial value and rate of change of the mean frequency, average rectified value and conduction velocity detected from the SCM and AS muscles during sub~maximal isometric cervical flexion contractions at 50, 25 and 10% MVC.

方法：58 位无特异性颈部疼痛的女性受试者被随机分配到两组为期 6 周的训练干预组：一组进行针对屈颈肌的耐力力量训练方法。另一组进行运动干预包括颅颈屈肌的低负荷训练。主要成果是最大随意收缩（MVC）力量的一个改变，初值改变和平均平率变化率，平均整流值以及 SCM 和 AS 肌肉在 50，25 和 10% MVC 次极等长颈椎屈曲收缩的传导速度检测

RESULTS: At the 7th week follow~up assessment, the endurance~strength training group revealed a significant increase in MVC force and a reduction in the estimates of the initial value and rate of change of the mean frequency for both the SCM and AS muscles (p < 0.05). Both exercise groups reported a reduced average intensity of neck pain and reduced neck disability index score (p < 0.05).

结果：在第七周随访时，耐力力量组在 MVC 力量显露出明显的增长，并在 SCM 和 AS 肌肉（p<0,05) 平均值的估计和平均频率变化率表现出减少。这两个运动组均呈现颈部疼痛平均强度的减少以及颈部伤残指数评分降低（p＜0.05）。

CONCLUSIONS:An endurance~strength exercise regime for the cervical flexor muscles is effective in reducing myoelectric manifestations of superficial cervical flexor muscle fatigue as well as increasing cervical flexion strength in a group of patients with chronic non~severe neck pain.

结论：一个针对颈部屈肌群的耐力力量运动方法能够有效的减少颈浅屈肌疲劳的肌电表现并增加有慢性非重度颈痛的一组受试者的颈椎曲屈强度。

SIGNIFICANCE: Provision of load to challenge the neck flexor muscles is required to reduce the fatigability of the SCM and AS muscles in people with neck pain. Improvements in cervical muscle strength and reduced fatigability may be responsible for the report of efficacy with this type of exercise program.

意义：减少颈部疼痛人们的 SCM 和 AS 肌肉的疲劳需要提供负载去挑战曲颈肌。这次报告表示该类型的运动方案能够提高颈部肌肉力量，减少颈部疲劳。
