Rowing races require developing high level of force and power output at high contraction velocity. This study determined the force-velocity and power-velocity (F-P-V) profiles of lower and upper limbs of adolescent rowers and their relationships with a 1,500-m rowing ergometer performance. The power developed during the 1,500-m (P) was evaluated in fourteen national-level male rowers (age: 15.3±0.6 yrs). F-P-V profiles were assessed during bench pull (BP) and squat jump (SJ) exercises. The theoretical maximal values of force (F), velocity (V), power output (P) and the F-V relationship slope (S ) were determined. The body mass (BM) influence on these relationships was considered using an allometric approach. F was 720±144 and 2146±405 N, V was 1.8±0.1 and 1.8±0.3 m·s, P was 333±83 and 968±204 W and S was -391±54 and -1,200±260 N·s·m for BP and SJ, respectively. Upper and lower limb F and P were significantly related. P was significantly (<0.05) correlated to V, F, S, P, F and P (r²=0.29 to 0.79). BM accounted for more than 90% of these relationships. Rowers' F-P-V profiles reflect adaptations to chronic rowing practice. F-P-V profiles and rowing performance correlations suggest that BP and SJ exercises are relevant to evaluate young rowers' explosive abilities.
赛艇比赛需要在高收缩速度下发展高水平的力量和功率输出。本研究确定了青少年赛艇运动员上下肢的力量-速度和功率-速度（F-P-V）曲线，并研究了它们与 1500 米划船测功仪表现之间的关系。在 14 名国家级男性赛艇运动员（年龄：15.3±0.6 岁）中评估了 1500 米（P）期间的功率。使用 bench pull (BP) 和 squat jump (SJ) 评估 F-P-V 曲线。确定了理论上的最大力量（F）、速度（V）、功率输出（P）和 F-V 关系斜率（S ）值。使用一种比例关系方法考虑了体重（BM）对这些关系的影响。BP 和 SJ 的 F 分别为 720±144 和 2146±405 N，V 分别为 1.8±0.1 和 1.8±0.3 m·s，P 分别为 333±83 和 968±204 W，S 分别为-391±54 和-1,200±260 N·s·m。上下肢的 F 和 P 呈显著相关。P 与 V、F、S、P、F 和 P（r²=0.29 至 0.79）显著相关。BM 占这些关系的 90%以上。赛艇运动员的 F-P-V 曲线反映了对慢性划船训练的适应。F-P-V 曲线和划船表现的相关性表明，BP 和 SJ 练习可用于评估年轻赛艇运动员的爆发力。
