This study explored the effects of concurrent-training (CT), resistance-only (R) and endurance-only (E) training on back squat one-repetition maximum (1RM), load-velocity profile (LVP) parameters and countermovement jump (CMJ). Thirty trained males were randomised into three groups (E, R, CT) and trained thrice-weekly for 11-weeks. R and CT groups completed a two-phase resistance training programme: maximal-strength (weeks 1-5) and explosive-strength (weeks 6-11). E and CT groups performed 30-minutes of running within the moderate-to-heavy-intensity domains. CT involved resistance followed by endurance training. LVP parameters (L, V, Slope and A), 1RM and CMJ height were assessed at baseline, mid-training and post-training. Back squat 1RM increased similarly in R and CT groups during the first phase but only in R during the second phase. CMJ height increased throughout both phases for R but only during the second for CT. R increased V and decreased Slope in both phases, while CT exhibited similar changes only during the second phase. A increased in R and CT during the first phase but improved only in R during the second. No significant changes occurred in the E group. CT impaired maximal and explosive strength adaptations compared to R, highlighting the need for tailored programmes to reduce interference effects.
本研究探讨了同时进行训练（CT）、仅进行阻力训练（R）和仅进行耐力训练（E）对后深蹲一次重复最大值（1RM）、负荷-速度曲线（LVP）参数和纵跳（CMJ）的影响。30名受过训练的男性被随机分为三组（E组、R组、CT组），每周训练三次，共训练11周。R组和CT组完成了一个两阶段的阻力训练计划：最大力量阶段（第1 - 5周）和爆发力阶段（第6 - 11周）。E组和CT组在中等到高强度范围内进行30分钟的跑步训练。CT组的训练包括先进行阻力训练，然后进行耐力训练。在基线、训练中期和训练后评估LVP参数（L、V、斜率和A）、1RM和CMJ高度。在第一阶段，R组和CT组的后深蹲1RM同样增加，但在第二阶段只有R组增加。R组在两个阶段中CMJ高度均增加，而CT组仅在第二阶段增加。R组在两个阶段中V增加，斜率降低，而CT组仅在第二阶段呈现类似变化。在第一阶段，R组和CT组的A增加，但在第二阶段只有R组得到改善。E组没有显著变化。与R组相比，CT组损害了最大力量和爆发力的适应性，这突出了需要制定针对性计划以减少干扰效应。
