Muscle strength is recognized as a key indicator of overall health and can help identify the risk of cardiometabolic disease. This study explores the relationship between low muscle strength, central obesity, and physical function among young adults.
We conducted a cross-sectional study from a convenience sample of 513 adults aged 18-25. Participants' anthropometric measures such as height, weight, and circumferences of both waist and hip were measured, and body mass index (BMI) was calculated. Subjects were tested for hand grip strength (HGS) using hand dynamometry. Relative hand grip strength (RHGS) was derived by dividing maximum HGS by BMI. Physical function was assessed using a six-minute walk test. The International Physical Activity Questionnaire (IPAQ) was administered.
Overweight and obesity were present in 313 (61%) of the study population. Central obesity was observed in 194 (37.8%) of the population. RHGS showed a positive association with physical function and physical activity, and a negative association was observed with BMI and waist circumference. Low RHGS was categorized as < 25th percentile by gender. The non-dynapenic non-central obese group had higher physical function (644± 124.2) than others. There was no difference in the dynapenic and central obese groups. The dynapenic central obese group had significantly lesser physical function (424.9±69.1) than all other groups in both genders.
Our study supports the importance of early investigation of dynapenia, which can increase the risk of chronic disease and accelerate the development of physical limitations. Understanding how dynapenia and central obesity relate to low physical function is of growing importance in young adults, and it can play an important role in overall health.
肌肉力量被认为是整体健康的关键指标，有助于识别心血管代谢疾病的风险。本研究探讨了年轻成年人中低肌肉力量、中心性肥胖与身体功能之间的关系。
我们对513名年龄在18至25岁的成年人进行了一项横断面研究，样本为便利抽样。测量了参与者的身高、体重、腰围和臀围等人体测量指标，并计算了体重指数（BMI）。使用握力计测试受试者的握力（HGS）。相对握力（RHGS）通过将最大握力除以BMI得出。使用六分钟步行测试评估身体功能。发放了国际体力活动问卷（IPAQ）。
研究人群中有313人（61%）超重和肥胖。194人（37.8%）存在中心性肥胖。相对握力与身体功能和体力活动呈正相关，与BMI和腰围呈负相关。根据性别，低相对握力被分类为低于第25百分位数。非肌肉减少性非中心性肥胖组的身体功能（644±124.2）高于其他组。肌肉减少性和中心性肥胖组之间没有差异。在男女两性中，肌肉减少性中心性肥胖组的身体功能（424.9±69.1）明显低于所有其他组。
我们的研究支持早期调查肌肉减少症的重要性，肌肉减少症会增加慢性病风险并加速身体功能受限的发展。了解肌肉减少症和中心性肥胖与低身体功能之间的关系在年轻成年人中日益重要，并且对整体健康可发挥重要作用。
