: The purpose of this study was to compare the effects of resistance training on stable versus unstable surfaces on strength performance in young judokas. : The study included 18 young judokas (age: 13.2 ± 1.2 years) with 4.7 years of training experience assigned to either the URT (unstable resistance training) group or the STG (stable resistance training) group. Both groups performed the bench press and squat exercise for 12 weeks (3 sessions/week, 30-40 min each), with one group performing on the stable surface and the other on the unstable surface. The tests included the 1RM bench press and squat, maximal power output during bench press and squat (Pmax), abdominal strength test (AB60), and the standing long jump (SLJ). : Statistical analyses revealed a group × time interaction for AB60 ( < 0.02) in favor of the URT group. Significant main effects of time ( < 0.01) for the 1RM bench press, 1RM squat, bench press power, AB60, and SLJ were found. There were no significant effects for squat maximal power in both groups ( ˃ 0.05). : Both unstable and stable resistance training effectively improved maximal strength and performance in adolescent judokas, with unstable training offering additional benefits in abdominal strength.
本研究的目的是比较在稳定表面与不稳定表面上进行阻力训练对年轻柔道运动员力量表现的影响。本研究纳入了18名年轻柔道运动员（年龄：13.2±1.2岁，训练经验4.7年），他们被分配到URT（不稳定阻力训练）组或STG（稳定阻力训练）组。两组均进行卧推和深蹲练习，为期12周（每周3次，每次30 - 40分钟），一组在稳定表面进行训练，另一组在不稳定表面进行训练。测试包括1RM卧推和深蹲、卧推和深蹲过程中的最大功率输出（Pmax）、腹部力量测试（AB60）以及立定跳远（SLJ）。统计分析显示，AB60存在组×时间交互作用（<0.02），有利于URT组。在1RM卧推、1RM深蹲、卧推功率、AB60和SLJ方面发现了显著的时间主效应（<0.01）。两组深蹲最大功率均无显著影响（>0.05）。不稳定和稳定阻力训练均能有效提高青少年柔道运动员的最大力量和表现，不稳定训练在腹部力量方面具有额外益处。
