Maciejewski, H, Rahmani, A, Chorin, F, Lardy, J, Samozino, P, and Ratel, S. Methodological considerations on the relationship between the 1,500-m rowing ergometer performance and vertical jump in national-level adolescent rowers. J Strength Cond Res 33(11): 3000-3007, 2019-The purpose of this study was to investigate whether 3 different approaches for evaluating squat jump performance were correlated with rowing ergometer performance in elite adolescent rowers. Fourteen young male competitive rowers (15.3 ± 0.6 years), who took part in the French rowing national championships, performed a 1,500-m all-out rowing ergometer performance (P1500) and a squat jump (SJ) test. The performance in SJ was determined by calculating the jump height (HSJ in cm), a jump index (ISJ = HSJ·body mass·gravity, in J), and the mean power output (PSJ in W) from the Samozino et al.'s method. Furthermore, allometric modeling procedures were used to consider the importance of body mass (BM) in the relationships between P1500 and jump scores. P1500 was significantly correlated with HSJ (r = 0.29, p ≤ 0.05), ISJ (r = 0.72, p < 0.0001), and PSJ (r = 0.86, p < 0.0001). Furthermore, BM explained at least 96% of the relationships between SJ and rowing performances. However, the similarity between both allometric exponents for PSJ and P1500 (1.15 and 1.04, respectively) indicates that BM could influence jump and rowing ergometer performances at the same rate, and that PSJ could be the best correlate of P1500. Therefore, the calculation of power seems to be more relevant than HSJ and ISJ to (a) evaluate jump performance and (b) infer the capacity of adolescent rowers to perform 1,500-m all-out rowing ergometer performance, irrespective of their body mass. This could help coaches to improve their training program and potentially identify talented young rowers.
马切伊耶夫斯基、拉赫曼尼、乔林、拉迪、萨莫津诺和拉特尔研究了国家级青少年赛艇运动员的 1500 米测功仪成绩与垂直跳跃之间的关系，提出了一些方法学上的考虑。研究目的是探讨 3 种不同的深蹲跳表现评估方法与精英青少年赛艇运动员的测功仪表现是否相关。14 名参加法国赛艇全国锦标赛的年轻男性竞技赛艇运动员（15.3±0.6 岁）进行了 1500 米全力测功仪表现（P1500）和深蹲跳（SJ）测试。SJ 的表现通过计算跳高技术（HSJ 以厘米为单位）、跳高技术指数（ISJ=HSJ·体重·重力，以焦耳为单位）和 Samozino 等人的方法计算的平均功率输出（PSJ 以瓦特为单位）来确定。此外，还使用了同态建模程序来考虑体重（BM）在 P1500 和跳跃得分之间关系中的重要性。P1500 与 HSJ（r=0.29，p≤0.05）、ISJ（r=0.72，p＜0.0001）和 PSJ（r=0.86，p＜0.0001）显著相关。此外，BM 至少解释了 SJ 和赛艇表现之间 96%的关系。然而，PSJ 和 P1500 的同态指数（1.15 和 1.04）之间的相似性表明，BM 可能以相同的速度影响跳跃和测功仪表现，而 PSJ 可能是 P1500 的最佳相关指标。因此，与 HSJ 和 ISJ 相比，计算功率似乎更能（a）评估跳跃表现，（b）推断青少年赛艇运动员进行 1500 米全力测功仪表现的能力，而与他们的体重无关。这有助于教练改善他们的训练计划，并有可能识别有天赋的年轻赛艇运动员。
