Performance in wheelchair basketball is determined by capabilities, such as strength and power. The study has two aims: first, to analyze the association between speed and acceleration variables (collected in the bench press (BP) exercise) and the distinct percentages of one-repetition maximum (1RM); second, to analyze the effect of a strength training protocol on wheelchair basketball (WB) players according to their functional impairments. Ten Spanish male WB players volunteered to participate in the study. The players did a pretest and posttest (1RM in bench press) with 6-week muscle strength intervention program. The results showed a high association between the %1RM and the mean propulsive velocity (MPV) and the maximum velocity (V), both in the total of the participants, and in each separate group of athletes. After implementing the strength training program, both the players of the IWBF (International Wheelchair Basketball Federation) < 2.5 group and those of IWBF > 2.5 group improved their 1RM ( < 0.01, ES = 0.20 to 0.23). However, the program produced positive effects at submaximal intensities in the MPV reached with 30, 40, 70, and 80 kg and in time to maximum velocity (TV) with 30, 40, and 70 kg (ES = -3.24 to 1.32) only in players with greater functional impairments. The high association between %1RM and MPV and V can allow for determination the %1RM of the WB players in the BP using the MPV and the V. The training program was effective in improving 1RM in both groups, while improvements in submaximal values only occurred in the IWBF < 2.5 group.
轮椅篮球运动表现取决于力量和爆发力等能力。本研究有两个目的：第一，分析速度和加速度变量（在卧推练习中收集）与不同百分比的一次重复最大值（1RM）之间的关联；第二，根据功能损伤情况分析力量训练方案对轮椅篮球（WB）运动员的影响。十名西班牙男性WB运动员自愿参与本研究。这些运动员在进行为期6周的肌肉力量干预计划前后分别进行了预测试和后测试（卧推的1RM）。结果显示，无论是在所有参与者中，还是在每个单独的运动员组中，1RM百分比与平均推进速度（MPV）和最大速度（V）之间都存在高度关联。实施力量训练计划后，国际轮椅篮球联合会（IWBF）<2.5组和IWBF>2.5组的运动员1RM均有所提高（<0.01，效应量=0.20至0.23）。然而，该计划仅对功能损伤较大的运动员在30、40、70和80千克负荷下达到的MPV以及30、40和70千克负荷下的最大速度时间（TV）的次最大强度产生了积极影响（效应量=-3.24至1.32）。1RM百分比与MPV和V之间的高度关联使得可以通过MPV和V来确定WB运动员在卧推中的1RM百分比。训练计划对两组运动员的1RM提高均有效，而次最大值的改善仅发生在IWBF<2.5组。
