The main purpose of this study was to assess relationships between absolute and relative handgrip strength (HGS) versus other markers of health (body composition) and physical fitness (VO max, vertical jump) in 220 (112 male) healthy young adults (25±10 years). HGS was measured using a hand dynamometer. Absolute HGS represented the highest grip strength measurement (kg) of the right and left hand combined, while relative HGS represented the absolute HGS divided by body weight (kg/kg). Body composition (lean and fat mass) was measured using dual energy x-ray absorptiometry. VO max was measured using a treadmill peak speed protocol (ml/kg/min), while vertical jump was assessed using a countermovement jump (cm). Absolute HGS (mean=86±22 kg) was positively related with lean mass (r=0.82, p<0.001) and vertical jump (r=0.63, p<0.001), while relative HGS (mean=1.2±0.2 kg/kg) was negatively related with body fat (r=-0.69, p<0.001), but positively correlated with VO max (r=0.47, p<0.001), and vertical jump (r=0.45, p<0.001). Linear models suggest that lean mass, body fat, and vertical jump predicted 69% of variance for absolute HGS (adjusted R =0.71, p<0.001), while lean mass and body fat predicted 49% of variance for relative HGS (adjusted R =0.49, p<0.001). Lower relative HGS scores (<1.0 kg/kg) were associated with higher body fat levels and may represent a quick, simple, marker of health.
本研究的主要目的是评估220名（112名男性）健康年轻成年人（25±10岁）的绝对和相对握力（HGS）与其他健康指标（身体成分）和体能指标（最大摄氧量、垂直跳）之间的关系。使用握力计测量握力。绝对握力代表左右手握力测量值（千克）的最高值，而相对握力代表绝对握力除以体重（千克/千克）。使用双能X线吸收法测量身体成分（瘦体重和脂肪量）。使用跑步机峰值速度方案（毫升/千克/分钟）测量最大摄氧量，而使用反向纵跳（厘米）评估垂直跳。绝对握力（平均值 = 86±22千克）与瘦体重（r = 0.82，p<0.001）和垂直跳（r = 0.63，p<0.001）呈正相关，而相对握力（平均值 = 1.2±0.2千克/千克）与体脂呈负相关（r = -0.69，p<0.001），但与最大摄氧量呈正相关（r = 0.47，p<0.001），与垂直跳呈正相关（r = 0.45，p<0.001）。线性模型表明，瘦体重、体脂和垂直跳可预测绝对握力69%的方差（调整后R² = 0.71，p<0.001），而瘦体重和体脂可预测相对握力49%的方差（调整后R² = 0.49，p<0.001）。较低的相对握力分数（<1.0千克/千克）与较高的体脂水平相关，可能是一个快速、简单的健康指标。
