The aim of this paper was to investigate the effect of short-term period, moderate intensity and high volume endurance training on physiological variables in elite wheelchair basketball players.
Eight wheelchair basketball players were examined. The subjects participated in a two-week intervention program of mainly two training types: wheelchair basketball and wheelchair driving endurance training. The subjects performed the continuously increasing cycling exercise (CCE) at the constant 60 rpm arm cranking speed at the beginning of the program and after two weeks of the program. The initial workload was 20 W, then the workload was increased by 2 W every 5 seconds until fatigue.
The post training of the wheelchair basketball group in the study showed a significant improvement in the peak oxygen uptake (VO2peak) and the peak power output (POpeak). VO2peak increased by 9% from 2.32±0.16 L/min to 2.53±0.2 L/min (P<0.05). POpeak increased by 28% from 141.75±14.23 W, to 181.63±26.3 W (P<0.05). The pre-training and post training test power output (PO [w]), relative power output (PO [w/kg]) increased significantly in all zones of energy production.
In conclusion, this study indicated that the wheelchair basketball squad had relatively high levels of aerobic fitness prior to participating in the endurance training program. Nevertheless, the high-volume, moderate-intensity, short-term training program, which evolved over the two-weeks period, resulted in the improvement of the athlete's aerobic endurance. The ventilatory threshold (VT) and the second ventilatory threshold (VT2) are good markers for aerobic capacity of wheelchair athletes.
本文旨在研究短期、中等强度和高运动量耐力训练对精英轮椅篮球运动员生理变量的影响。
对8名轮椅篮球运动员进行了检查。受试者参加了为期两周的干预计划,主要包括两种训练类型:轮椅篮球和轮椅驾驶耐力训练。在计划开始时和计划进行两周后,受试者以每分钟60转的恒定手臂曲柄速度进行持续递增的循环运动(CCE)。初始工作量为20瓦,然后每5秒工作量增加2瓦,直至疲劳。
研究中轮椅篮球组的训练后,峰值摄氧量(VO2peak)和峰值功率输出(POpeak)有显著改善。VO2peak从2.32±0.16升/分钟增加到2.53±0.2升/分钟,增幅为9%(P<0.05)。POpeak从141.75±14.23瓦增加到181.63±26.3瓦,增幅为28%(P<0.05)。在所有能量产生区域,训练前和训练后的测试功率输出(PO[瓦])、相对功率输出(PO[瓦/千克])均显著增加。
总之,本研究表明,轮椅篮球运动员在参加耐力训练计划之前具有较高水平的有氧适能。然而,在两周时间内进行的高运动量、中等强度的短期训练计划,使运动员的有氧耐力得到了提高。通气阈值(VT)和第二通气阈值(VT2)是轮椅运动员有氧能力的良好指标。
