Blanco, P, Nimphius, S, Seitz, LB, Spiteri, T, and Haff, GG. Countermovement jump and drop jump performances are related to grand jeté leap performance in dancers with different skill levels. J Strength Cond Res 35(12): 3386-3393, 2021-Thirty-five classical ballet dancers were chosen to investigate relationships between the grand jeté leap, countermovement jump (CMJ), and drop jump (DJ) and establish whether the magnitude of the relationship between these tests differed across 3 skill levels. Subjects (male: n = 11 and female: n = 24) were divided into 3 groups: novice (n = 12; age: 16.6 ± 1.5 years; height: 1.7 ± 0.1 m; body mass: 58.0 ± 13.0 kg), semiprofessional (n = 13; age: 20.0 ± 1.6 years; height: 1.7 ± 0.1 m; body mass: 64.1 ± 10.5 kg), and professional (n = 10; age: 23.8 ± 3.5 years; height: 1.8 ± 1.2 m; body mass: 63.3 ± 14.7 kg). Grand jeté leap height, followed by CMJ and DJ vertical displacement, was assessed. Significant relationships were found between the grand jeté, CMJ (r = 0.77, p = 0.001) and DJ (r = 0.76, p = 0.001). After a Fisher's r-z transformation, professional dancers and novice dancers showed greater r-value differences in CMJ (r2 - r1 = 0.27) compared with novice (r2 - r1 = 0.17) and semiprofessional dancers (r2 - r1 = 0.11), indicating larger strength of CMJ to grand jeté relationship in professionals. The grand jeté leap showed large to very large correlations with CMJ and DJ within groups. These common performance tests were determined to be practical and efficient methods for assessing the jumping ability of dancers. As dance skill increased, larger correlations were observed, suggesting that dancers with superior ballet skills may be more likely to use their underpinning physical capacities to jump higher within the context of ballet-specific jumping.
布兰科、Nimphius、Seitz、斯皮特里和哈夫选取了 35 名古典芭蕾舞演员进行研究，以调查其空中劈叉跳跃、深蹲跳和俯跳下蹲跳与空中劈叉跳跃之间的关系，并确定这些测试之间的关系幅度是否因 3 个技能水平的不同而有所差异。受试者（男性：n=11，女性：n=24）被分为 3 组：新手组（n=12；年龄：16.6±1.5 岁；身高：1.7±0.1m；体重：58.0±13.0kg）、半专业组（n=13；年龄：20.0±1.6 岁；身高：1.7±0.1m；体重：64.1±10.5kg）和专业组（n=10；年龄：23.8±3.5 岁；身高：1.8±1.2m；体重：63.3±14.7kg）。评估了空中劈叉跳跃高度，其次是深蹲跳和俯跳下蹲跳的垂直位移。发现空中劈叉、深蹲跳（r=0.77，p=0.001）和俯跳下蹲跳（r=0.76，p=0.001）之间存在显著关系。经过 Fisher r-z 变换后，专业舞者和新手舞者在深蹲跳中的 r 值差异更大（r2-r1=0.27），而新手（r2-r1=0.17）和半专业舞者（r2-r1=0.11）之间的差异较小，这表明专业舞者的深蹲跳与空中劈叉跳跃之间的关系更强。在各个组内，空中劈叉跳跃与深蹲跳和俯跳下蹲跳之间都存在较大到非常大的相关性。这些共同的性能测试被确定为评估舞者跳跃能力的实用且有效的方法。随着舞蹈技能的提高，观察到更大的相关性，这表明具有较高芭蕾舞技能的舞者可能更有可能在芭蕾舞特定跳跃的背景下，利用其潜在的身体能力跳得更高。
