Rugby players need muscular strength and power to meet the demands of the sport; therefore, a proper assessment of the performance in rugby players should include both variables. The purpose of this study was to examine the strength and power characteristics (SPC) during the squat (SQ) and bench press (BP) in national amateur rugby players and to analyze gender- and position-related differences. A total of 47 players (30 males and 17 females; age: 25.56 ± 1.14 and 23.16 ± 1.38 years, respectively) participated in the study. The one repetition-maximum (1-RM) and SPC in SQ and BP were obtained using a Smith Machine. Then, subjects performed one set of five repetitions on the SQ and BP against six relative loads (30-40-50-60-70-80% 1-RM) using a linear transducer. Differences between genders were found in 1-RM for maximal power, kilograms lifted at maximal power, maximal power, maximal strength and maximal speed in BP ( < 0.00) and 1-RM, kilograms lifted at maximal power, maximal power, maximal strength and maximal speed in SQ ( < 0.00). Comparisons between variables in SQ and BP present a significant relationship ( < 0.01) in SQ and BP 1-RM with kilograms lifted at maximal power = 0.86 and r = 0.84), maximal strength ( = 0.53 and = 0.92) and maximal power ( = 0.76 and = 0.93). This study confirms the importance of the SPC assessment for training prescription in rugby amateur players.
橄榄球运动员需要肌肉力量和爆发力来满足这项运动的要求；因此，对橄榄球运动员的表现进行恰当评估应包括这两个变量。本研究的目的是研究国家业余橄榄球运动员在深蹲（SQ）和卧推（BP）过程中的力量和爆发力特征（SPC），并分析性别和位置相关的差异。共有47名运动员（30名男性和17名女性；年龄分别为25.56±1.14岁和23.16±1.38岁）参与了该研究。使用史密斯机获得SQ和BP的一次重复最大值（1-RM）和SPC。然后，受试者使用线性传感器在SQ和BP上针对六个相对负荷（30%-40%-50%-60%-70%-80% 1-RM）进行一组五次重复动作。在BP中，发现性别之间在最大功率的1-RM、最大功率时举起的千克数、最大功率、最大力量和最大速度方面存在差异（<0.00），在SQ中，1-RM、最大功率时举起的千克数、最大功率、最大力量和最大速度方面也存在差异（<0.00）。SQ和BP中变量之间的比较表明，SQ和BP的1-RM与最大功率时举起的千克数（r = 0.86和r = 0.84）、最大力量（r = 0.53和r = 0.92）和最大功率（r = 0.76和r = 0.93）之间存在显著关系（<0.01）。本研究证实了SPC评估对橄榄球业余运动员训练处方的重要性。
