研究背景有氧和肌肉强化活动与疾病的发病率和死亡率有关。阻力锻炼/力量训练项目被纳入国家调查，但这些调查对肌肉强化活动的质疑方式各不相同。目的本研究的目的是使用不同的自我报告措施来检查女性在肌肉强化活动方面符合2008年美国身体活动指南的普遍性。方法我们调查了606个社区-居住的妇女在4个时间点在1.5至3年的时间内，以确定是否符合受访者进行肌肉强化活动每周≥ 2天的国家体育活动指南。如果被要求反映过去一个月的情况或关于参与的典型天数的一般性问题，大约40%的女性报告每周参与≥ 2天的抗阻运动/力量训练。然而，当每周获得的报告为13周，只有约18%的受访者符合guidelines.ConclusionResults表明，提问的时间和性质可以大大影响自我报告的流行肌肉加强身体活动的社区居住的妇女。
BackgroundAerobic and muscle-strengthening activities are related to morbidities and mortality. Resistance exercise/strength training items are included in national surveys, but the manner in which muscle-strengthening activity is queried varies among these surveys.PurposeThe purpose of this study was to use different self-report measures to examine the prevalence of meeting the2008 Physical Activity Guidelines for Americansregarding muscle-strengthening activities among women.MethodsWe surveyed 606 community-dwelling women at 4 points in time across a 1.5- to 3-year time period to determine whether the respondents met the national physical activity guidelines for performing muscle-strengthening activities ≥ 2 days per week.ResultsResults were consistent across time but depended on the manner in which the question was asked. If asked to reflect over the past month or a general question about the typical number of days engaged, approximately 40% of women reported engaging in ≥ 2 days per week of resistance exercise/strength training. However, when reports were obtained weekly for 13 weeks, only approximately 18% of respondents met the guidelines.ConclusionResults indicate that the timing and nature of questioning can substantially influence the self-reported prevalence of muscle-strengthening physical activities for community-dwelling women.
