Abstract：
The current UK physical activity guidelines recommend that adults aged 19 to 65 years perform activity to strengthen muscle and bone a minimum of twice weekly. The number of adults meeting strengthening activity guidelines is lower than for aerobic activity, but estimates vary between studies partly due to differences in how muscle-strengthening activity is defined. We aimed to provide estimates for strengthening activity prevalence in English adults based on a nationally representative sample of n = 253,423 18-65-year-olds. We attempted to quantify the variation in estimates attributable to differences in the way strengthening activity is defined. Finally, we aim to provide a brief descriptive epidemiology of the factors associated with strengthening activity. Adults met guidelines for aerobic activity if they reported the activity equivalent to >150 min/week moderate-intensity exercise. Respondents met strengthening guidelines if they reported at least two bouts per week of strengthening activity. We defined strengthening activity, first, according to criteria used in the Health Survey for England (HSE). Second, we counted bouts of strengthening activities for which we could find evidence of health-related benefits (Evidence). Third, we included bouts of strengthening activity as defined in current UK physical activity guidelines (Guideline). Two-thirds (67%) of adults met guidelines for aerobic activity (69% of men, 65% of women). Less than one-third (29% of men and 24% of women) met guidelines for the HSE definition of strengthening activity. Under the Evidence definition, 16% of men and 9% of women met strengthening guidelines. Using the most-stringent definition (Guideline) just 7.3% of men and 4.1% of women achieved the recommendations for strengthening activity. We found females and older adults (50-65 years) were less likely to meet guidelines for aerobic, strengthening, and combined aerobic plus strengthening activity. The prevalence of meeting activity guidelines was lower in adults from more deprived areas (compared with the least deprived); Adults with lower academic qualifications (Level 1) were less likely to meet activity guidelines than those educated to Level 4 (Degree Level) or higher. Having a limiting disability was associated with a lower prevalence of meeting activity guidelines. Associations between socio-demographic measures and the prevalence of adults meeting activity guidelines were stronger for strengthening activity than for aerobic 51(or combined aerobic plus strengthening) activity Compared with aerobic activity, fewer adults engage in strengthening activity regardless of how it is defined. The range in estimates for how many adults meet strengthening activity guidelines can be explained by variations in the definition of \'strengthening\' that are used and the specific sports or activities identified as strengthening exercise. When strengthening activity is included, the proportion of English adults meeting current physical activity guidelines could be as high as 1 in 3 but possibly as low as just 1 in 20. A harmonized definition of strengthening activity, that is aligned with physical activity guidelines, is required to provide realistic and comparable prevalence estimates.
摘要：
目前的英国体育活动指南建议19至65岁的成年人每周至少两次进行活动以增强肌肉和骨骼。符合强化活动指引的成人人数低于有氧活动,但不同研究之间的估计有所不同，部分原因是肌肉强化活动的定义不同。我们旨在根据n=253,42318-65岁的全国代表性样本，为加强英国成年人的活动患病率提供估计值。我们试图量化归因于强化活动定义方式差异的估计值差异。最后,我们的目的是提供与强化活动相关因素的简要描述流行病学.如果成年人报告的有氧活动相当于>150分钟/周的中等强度运动，则符合有氧活动指南。如果受访者报告每周至少有两次加强活动，则符合加强准则。我们定义了加强活动，首先,根据英国健康调查(HSE)中使用的标准。第二,我们计算了加强活动的回合，我们可以找到与健康相关的益处的证据（证据）。第三，我们纳入了当前英国体力活动指南(Guideline)中定义的强化活动。三分之二（67％）的成年人符合有氧活动指南（69％的男性，65%的妇女）。不到三分之一(29%的男性和24%的女性)符合HSE强化活动定义的指导方针。根据证据定义,16%的男性和9%的女性符合强化指南。使用最严格的定义（准则），只有7.3％的男性和4.1％的女性达到了加强活动的建议。我们发现女性和老年人（50-65岁）不太可能符合有氧运动指南，加强,有氧运动和强化运动相结合。在更贫困地区的成年人中（与最不贫困的地区相比），满足活动准则的患病率较低；学历较低（1级）的成年人与受过4级（学位）或更高教育的成年人相比，满足活动准则的可能性较小。患有限制性残疾与满足活动指南的患病率较低有关。与有氧活动相比，社会人口统计学指标与满足活动指南的成年人的患病率之间的关联比有氧51（或有氧加加强的组合）活动更强。较少的成年人从事加强活动，无论它是如何定义。估计有多少成年人符合加强活动指南的范围可以通过使用的“加强”定义的变化以及被确定为加强运动的特定运动或活动来解释。当包括加强活动时，符合现行体育活动指南的英国成年人比例可能高达1/3，但可能低至1/20。加强活动的统一定义，与身体活动指南一致，需要提供现实和可比的流行率估计。
