The aim of the present study was to compare the load-power curve expressed at bench press (PR) and prone bench pull (PU) between elite swimmers and kayakers. Another aim was to calculate the strength and power PR/PU ratio in the same populations. Fifteen elite swimmers (SW: age = 23.8 ± 2.9 y; body mass = 82.8 ± 5.6 kg; body height = 184.1 ± 4.6 cm) and 13 elite kayakers (KA: age = 23.8 ± 2.9 y; body mass = 91.0 ± 3.5 kg; body height = 180.1 ± 5.4 cm) were assessed for PR 1RM and PU 1RM. They were then assessed for power produced at 40, 60 and 80% of 1RM in both PR and PU. The area under the load-power curve (AUC) and PR/PU ratios were calculated for both the SW and KA groups. The KA group showed significantly higher PR1RM (+18.2%; = 0.002) and PU1RM (+25.7%; < 0.001) compared to the SW group. Significant group differences were also detected for PUAUC ( < 0.001) and for the PR/PU power ratio ( < 0.001). No significant group differences were detected for PRAUC ( = 0.605) and for the PR/PU strength ratio ( = 0.065; 0.87 and 0.82 in SW and KA, respectively). The present findings indicate that elite KA were stronger and more powerful than elite SW in the upper body. Not consistently with other athletic populations, both KA and SW athletes were stronger and more powerful in upper body pull compared to push moves.
本研究的目的是比较优秀游泳运动员和皮划艇运动员在卧推（PR）和俯姿卧拉（PU）中的负荷-功率曲线。另一个目的是计算同一人群中 PR 和 PU 的力量和功率比。15 名优秀游泳运动员（SW：年龄=23.8±2.9 岁；体重=82.8±5.6 公斤；身高=184.1±4.6 厘米）和 13 名优秀皮划艇运动员（KA：年龄=23.8±2.9 岁；体重=91.0±3.5 公斤；身高=180.1±5.4 厘米）评估了 PR1RM 和 PU1RM。然后，他们在 PR 和 PU 中以 1RM 的 40%、60%和 80%评估了产生的功率。为 SW 和 KA 组计算了负荷-功率曲线下面积（AUC）和 PR/PU 比值。与 SW 组相比，KA 组的 PR1RM（+18.2%；=0.002）和 PU1RM（+25.7%；<0.001）显著更高。还检测到了 PUAUC（<0.001）和 PR/PU 功率比（<0.001）的显著组间差异。没有检测到 PRAUC（=0.605）和 PR/PU 力量比（=0.065；SW 和 KA 分别为 0.87 和 0.82）的显著组间差异。本研究结果表明，与优秀游泳运动员相比，优秀皮划艇运动员在上半身更强壮、更有力。与其他运动人群不一致的是，与推类动作相比，皮划艇和游泳运动员在上半身拉类动作中更强壮、更有力。
