背景:上肢和下肢肌力可用于预测健康结果。然而,上肢肌肉和下肢肌肉与生理因素之间的关系尚不清楚。这项研究旨在评估生理数据和肌肉力量之间的关联,使用握力和腿部伸展强度测量,在日本成年人中。
方法:我们对居住在宫城县的2,861名男性和6,717名年龄≥20岁的女性进行了横断面研究。日本。使用测力计测量握力。使用液压等速压腿机测量腿部伸展强度。人体测量和生理数据,包括血压,跟骨超声骨状态,肺功能,颈动脉回波描记术,和血液信息,被评估。我们使用了根据年龄调整的一般线性模型,身体成分,和吸烟状况来评估肌肉力量与生理因素之间的关系。
结果:握力和腿部伸展强度与骨面积比呈正相关,肺活量,强制肺活量,一秒钟内用力呼气量,和估计的肾小球滤过率,与男女腰围和体脂百分比呈负相关。在男性中,舒张血压与性别的握力和腿部伸展力呈正相关,但不是女人。高密度脂蛋白胆固醇和红细胞计数与女性握力和腿部伸展力量呈正相关,但不是男人。在两性中,脉搏率,总胆固醇,和尿酸一直只与腿部伸展力量有关,但不是握力。在女性中,糖化血红蛋白与握力和腿部伸展力量呈负和正相关,分别。
结论:握力和腿部伸展强度与人体测量学相似,肺功能,和估计的肾小球滤过率,但与其他因素的关联并不总是一致的.
BACKGROUND: Upper and lower extremity muscle strength can be used to predict health outcomes. However, the difference between the relation of upper extremity muscle and of lower extremity muscle with physiological factors is unclear. This study aimed to evaluate the association between physiological data and muscle strength, measured using grip and leg extension strength, among Japanese adults.
METHODS: We conducted a cross-sectional study of 2,861 men and 6,717 women aged ≥ 20 years living in Miyagi Prefecture, Japan. Grip strength was measured using a dynamometer. Leg extension strength was measured using a hydraulic isokinetic leg press machine. Anthropometry and physiological data, including blood pressure, calcaneal ultrasound bone status, pulmonary function, carotid echography, and blood information, were assessed. We used a general linear model adjusted for age, body composition, and smoking status to evaluate the association between muscle strength and physiological factors.
RESULTS: Grip and leg extension strength were positively associated with bone area ratio, vital capacity, forced vital capacity, forced expiratory volume in one second, and estimated glomerular filtration rate, and negatively associated with waist circumference and percentage body fat mass in both the sexes. Diastolic blood pressure was positively associated with grip strength in both the sexes and leg extension strength in men, but not women. High-density lipoprotein cholesterol and red blood cell counts were positively associated with grip and leg extension strength in women, but not men. In both the sexes, pulse rate, total cholesterol, and uric acid were consistently associated with only leg extension strength, but not grip strength. In women, glycated hemoglobin demonstrated negative and positive associations with grip and leg extension strength, respectively.
CONCLUSIONS: Grip and leg extension strength demonstrated similar associations with anthropometry, pulmonary function, and estimated glomerular filtration rate, but the associations with the other factors were not always consistent.
