是否感到有些抑郁,？試試散步吧,。這是許多醫(yī)學(xué)專家推薦的治療輕度抑郁的方法。英國一項最新研究再次支持了散步在緩解抑郁方面的有效性。相關(guān)論文發(fā)表在《精神健康與身體運(yùn)動》（Mental Health and Physical Activity ）雜志上,。
英國斯特林大學(xué)等機(jī)構(gòu)的研究人員報告說,，他們對過去有關(guān)抑郁和散步的大量研究進(jìn)行綜合整理和分析，從中挑選出300多名適合對比分析的抑郁患者的數(shù)據(jù),，最終得出的結(jié)論是散步在幫助治療抑郁方面的確有效,。
據(jù)介紹，醫(yī)學(xué)界早就知道運(yùn)動有助于治療抑郁,，對一些輕度抑郁患者來說,，常見的醫(yī)療建議不是服用抗抑郁藥，而是試試運(yùn)動的效果,。但是散步這種強(qiáng)度不大的運(yùn)動是否也有類似的效果,，過去相關(guān)研究的結(jié)果不完全一致。本次綜合性文獻(xiàn)回顧的結(jié)果支持了散步的有效性,。不過研究人員也表示,，對散步功效的一些細(xì)節(jié)還需要深入研究，比如對某種程度的抑郁患者來說,，要通過散步達(dá)到較好的效果,，需要每天散步多長時間、最佳的步伐速率是多少等,，這些問題都還尚待解答,。（生物谷Bioon.com）

Walking for depression or depressive symptoms: a systematic review and meta-analysis

Problem
Depression is a common disorder worldwide. Most patients are treated within primary care and antidepressant treatment is not recommended for people with mild depression. Physical activity has been shown to alleviate depression but it is not known whether the less vigorous activity of walking – a potentially widely acceptable and safe intervention - confers such benefit.
Method
Eleven databases were systematically searched for randomised controlled trials of walking as a treatment intervention for depression, from database inception until January 2012. Meta-analyses were carried out on all trials eligible for inclusion and on sub-groups of outdoor, indoor and group walking.
Results
Of the 14,672 articles retrieved, eight trials met the inclusion criteria. The pooled standardised mean difference (effect size) was -0.86 [-1.12, -0.61] showing that walking has a statistically significant, large effect on symptoms of depression. However, there was considerable heterogeneity amongst the interventions and research populations and it is uncertain whether the results can be generalised to specific populations such as primary care patients.
Conclusions
Walking has a statistically significant, large effect on the symptoms of depression in some populations, but the current evidence base from randomised, controlled trials is limited. Thus, while walking is a promising treatment for depression or depressive symptoms with few, if any, contraindications, further investigations to establish the frequency, intensity, duration and type(s) of effective walking interventions particularly in primary care populations would be beneficial for providing further recommendations to clinical practitioners.
