    Being physically active is often suggested to be important in the prevention and management of low back pain. This simple view does not take into account that the relation between the level of activity and back pain may be a U-shaped curve - i.e. both inactivity and excessive activities (back-unhealthy activity) present an increased risk for back pain. We explored the U-shaped association between physical activity and chronic low back pain (3 months duration) by analyzing cross-sectional data from the Dutch population-based Musculoskeletal Complaints and Consequences Cohort study (DMC(3), 1998) of a sex-age stratified sample of 25 years and older (n=3364). Type of activity (daily routine, leisure time and sport activity), intensity of and time spent on these activities, and back exertion of sport activities were taken into account. Physical activity was not associated with chronic low back pain (CLBP) when studied by the dimension of activity, by the intensity or by the duration of physical activity. Only engaging in sport activity was associated with less CLBP (OR 0.78: 95% CI 0.66-0.93). The extremes of the total physical activity pattern were associated with CLBP. A moderate increased risk for CLBP was found for both participants with a sedentary lifestyle (OR 1.31: 95% CI 1.08-1.58) and for those being involved in physical strenuous activities (OR 1.22: 95% CI 1.00-1.49). This was especially true for women (sedentary: OR 1.44: 95% CI 1.10-1.83; physically active: OR 1.36: 95% CI 1.04-1.78). This study provides some evidence that the relation between physical activity and CLBP is U-shaped.

    体力活动与腰痛的关系(转)
    体力活动和腰痛是处于什么样的关系呢?体力活动会增加腰痛,还是会预防腰痛呢?下面报道一篇来自荷兰的文章,他给出的建议是活动太少与太多都会导致腰痛。
    一些研究已经显示大强度的活动会导致腰痛,例如:腰部的旋转、弯曲、举重和极限的运动。也有一些研究指出活动太少会导致腰痛。那问题就出现了:那么多大强度的活动才能预防腰痛呢?
    我们并不能很容易回答这个问题,因为有太多因素需要考虑。例如:个体从事的职业,是否参加业余活动,举重和搬东西的活动都是导致腰痛的潜在因素。
    1998年,有报道称体力活动的强度与腰痛呈U形的关系。U形中间的底部为适度的体力活动,远离适度体力活动的强度会导致腰痛。
    该作者目的是测试这个理论。他们对8000人发送问卷调查,关于健康、体力活动的强度、腰痛的流行病学、发生腰痛看医生的次数。病人的基本资料包括年龄、性别、职业、教育背景、健康的感觉。
    并不是所有的研究采用同样的标准。根据强度主要分为三组:低、适中、强。每个类别都基于受试者的年龄与代谢当量(MET
    代谢当量是测试体力活动强度的指标。对于年轻受试者来说:低强度为2-4MET、适中强度为4-6.5MET、大强度为>6.5MET。对于老年人来说:低强度为<3MET、适中强度为3-5MET、大强度为>5MET
    根据锻炼的时间划分为:适中强度为每周至少练习五天,每天锻炼半小时;低强度定义为少于适中强度的时间;高强度为每天锻炼数小时。
     
    结果显示体力活动强度确实与慢性腰痛是U形的关系。有11%的受试者是低强度锻炼,并且他们比适中强度锻炼的受试者更容易发生腰痛。
    然而,30%高强度锻炼的受试者也发生腰痛。女性与男性相比,更接近U形关系,目前原因还不明。
    体力活动的种类也存在不同的关系,参加体育活动的受试者发生腰痛的几率比较低。
    结论:不同强度的体力活动发生腰痛的也是不同的,低强度与高强度是导致腰痛高风险因素,正如U形结构的两侧。

不知道这篇文章有没有研究运动后放松的情况。高强度运动之后一定要做到放松肌肉和腰部,比如反方向压一压,在活动的关节和背部捶一捶,这些都太重要了,必要的话,洗个热水澡并按摩一下。

我想文章还是侧重不同的运动强度和疼痛之间做了关联分析,是做单因素分析的,如果要考虑运动后放松,是多因素分析了,会提高研究的复杂性。当然了,也是可靠性。
不过,从这个U形曲线来说,这个曲线是可预测和可理解的
