The significance of isometric muscle strength for rowing performance was studied. The questions investigated were: A) Is the isometric rowing strength (IRS) of oarsmen which is two to three times the dynamic force applied on the oar at maximal power rowing, a ratio which is equivalent to the maximal efficiency of Hill's force/velocity relationship? B) Is IRS higher among successful oarsmen that among those less so? C) Is isometric strength of individual muscle groups correlated to IRS? From measurments on 40 oarsmen the results showed: a) IRS among the most successful oarsmen was 2.6 times the dynamic force indicated in literature; b) IRS was 21 kp higher in the 7 international competitive oarsmen than in 22 national oarsmen, and 42 kp higher than IRS of 11 club oarsmen; and c) of eight other strength determinations only hand grip strength was correlated to IRS. It is suggested that IRS, but not isometric strength of individual muscle groups limits rowing performance.
研究了等长肌肉力量对划船成绩的重要性。所调查的问题如下：A）桨手的等长划船力量（IRS）是最大功率划船时施加在桨上的动力的两到三倍，这一比例是否等同于希尔力/速度关系的最大效率？B）成功的桨手的IRS是否高于不太成功的桨手？C）各个肌肉群的等长力量与IRS是否相关？对40名桨手的测量结果表明：a）最成功的桨手中的IRS是文献中所指出的动力的2.6倍；b）7名国际比赛桨手的IRS比22名国家桨手高21kp，比11名俱乐部桨手的IRS高42kp；c）在其他八项力量测定中，只有握力与IRS相关。研究表明，限制划船成绩的是IRS，而不是各个肌肉群的等长力量。
