Neck and shoulder complaints are common among employees in sedentary occupations characterized by intensive computer use. Specific strength training is a promising type of physical exercise for relieving neck and shoulder pain in office workers. However, the optimal combination of frequency and exercise duration, as well as the importance of exercise supervision, is unknown. The VIMS study investigates in a cluster randomized controlled design the effectiveness of different time wise combinations of specific strength training with identical accumulated volume, and the relevance of training supervision for safe and effective training.
METHODS/DESIGN: A cluster randomized controlled trial of 20 weeks duration where employed office workers are randomized to 1 x 60 min, 3 x 20 min, 9 x 7 min per week of specific strength training with training supervision, to 3 x 20 min per week of specific strength training with a minimal amount of training supervision, or to a reference group without training. A questionnaire will be sent to 2000 employees in jobs characterized by intensive computer work. Employees with cardiovascular disease, trauma, hypertension, or serious chronic disease will be excluded. The main outcome measure is pain in the neck and shoulders at week 20.
The trial is registered at ClinicalTrials.gov, number NCT01027390.
在以密集使用计算机为特点的久坐职业中，颈部和肩部的不适是常见的。特定的力量训练是一种很有前途的体育锻炼方式，可以缓解上班族的颈部和肩部疼痛。然而，频率和运动持续时间的最佳组合，以及运动监督的重要性，尚不清楚。VIMS 研究采用集群随机对照设计，调查特定力量训练的不同时间组合与相同累积量的效果，以及训练监督对安全有效训练的相关性。
方法/设计：一项为期 20 周的集群随机对照试验，其中上班族被随机分为 1 组，每周 60 分钟；3 组，每周 20 分钟，共 3 次；9 组，每周 7 分钟，均接受特定力量训练和监督；每周 3 次 20 分钟的特定力量训练，监督最少；或参考组，不进行训练。将向 2000 名从事密集计算机工作的员工发送一份问卷。患有心血管疾病、创伤、高血压或严重慢性疾病的员工将被排除在外。主要结局指标是第 20 周时颈部和肩部的疼痛。
该试验在 ClinicalTrials.gov 注册，编号为 NCT01027390。
