8月6日，《内科学文献》(<em>Arch Intern Med</em>)发表的一项新的研究表明，不只是有氧运动，负重训练也可以降低糖尿病的风险。
波士顿哈佛大学公共卫生学院弗兰克·胡博士说：“我们都知道，有氧运动对糖尿病是有益的，这已经得到了很多研究的检验，但是，还没有研究来验证负重训练对于糖尿病的作用”。 “研究表明，负重训练对糖尿病是非常重要的，可能起到与有氧运动有相同的功效。”他告诉路透社健康栏目的记者。

胡博士和他的同事们使用了超过32，000多名男性健康专业人士的数据，这些人士从1998年到2008年，每两年都要接受问卷调查。 研究人员发现，平均来看，每年每1000人中会有4个人发展成2型糖尿病。
有氧运动的男士，发生血糖紊乱的风险只有不进行有氧运动人的一半，这里的有氧运动是指每周至少进行150分钟以上快走，慢跑或打网球等运动。相比那些从未进行过负重训练的人来说，每周进行150分钟以上或更长时间负重训练的男士发展成糖尿病的风险降低了三分之一，与他们是否做有氧运动无关。
胡博士表示，负重训练能够增加肌肉质量，并能降低腹部肥胖，它往往不是减少整体的体重。结果并没有证明锻炼身体可以避开糖尿病，因为很多保持身材的男人在其他方面也很健康。但研究人员尽最大努力去解释这种潜在的差异，包括年龄，吸烟，饮食 胡博士说:”我认为负重训练的好处是真的，任何类型的运动对于预防糖尿病都是有益的，但可以将负重训练纳入到有氧运动中，以获得最佳效果。“
他补充说，运动和适当的饮食一起能够帮助控制高血糖，对糖尿病患者非常重要。

<br/><strong>A Prospective Study of Weight Training and Risk of Type 2 Diabetes Mellitus in Men.</strong><br/>

Abstract
BACKGROUND The role of weight training in the primary prevention of type 2 diabetes mellitus (T2DM) is largely unknown. METHODS To examine the association of weight training with risk of T2DM in US men and to assess the influence of combining weight training and aerobic exercise, we performed a prospective cohort study of 32 002 men from the Health Professionals Follow-up Study observed from 1990 to 2008. Weekly time spent on weight training and aerobic exercise (including brisk walking, jogging, running, bicycling, swimming, tennis, squash, and calisthenics/rowing) was obtained from questionnaires at baseline and biennially during follow-up. RESULTS During 508 332 person-years of follow-up (18 years), we documented 2278 new cases of T2DM. In multivariable-adjusted models, we observed a dose-response relationship between an increasing amount of time spent on weight training or aerobic exercise and lower risk of T2DM (P &lt; .001 for trend). Engaging in weight training or aerobic exercise for at least 150 minutes per week was independently associated with a lower risk of T2DM of 34% (95% CI, 7%-54%) and 52% (95% CI, 45%-58%), respectively. Men who engaged in aerobic exercise and weight training for at least 150 minutes per week had the greatest reduction in T2DM risk (59%; 95% CI, 39%-73%). CONCLUSIONS Weight training was associated with a significantly lower risk of T2DM, independent of aerobic exercise. Combined weight training and aerobic exercise conferred a greater benefit.
