A bioenergetical analysis of manoeuvrability and agility performance for wheelchair players is inexistent. It was aimed at comparing the physiological responses and performance obtained from the octagon multistage field test (MFT) and the modified condition in "8 form" (MFT-8). Sixteen trained wheelchair basketball players performed both tests in randomized condition. The levels performed (end-test score), peak values of oxygen uptake (VO2peak), minute ventilation (VEpeak), heart rate (HRpeak), peak and relative blood lactate (Δ[Lact(-)] = peak--rest values), and the perceived rating exertion (RPE) were measured. MFT-8 induced higher VO2peak and VEpeak values compared to MFT (VO2peak: 2.5 ± 0.6 versus 2.3 ± 0.6 L · min(-1) and VEpeak: 96.3 ± 29.1 versus 86.6 ± 23.4 L · min(-1); P < 0.05) with no difference in other parameters. Significant relations between VEpeak and end-test score were correlated for both field tests (P < 0.05). At exhaustion, MFT attained incompletely VO2peak and VEpeak. Among experienced wheelchair players, MFT-8 had no effect on test performance but generates higher physiological responses than MFT. It could be explained by demands of wheelchair skills occurring in 8 form during the modified condition.
目前尚无针对轮椅运动员机动性和敏捷性表现的生物能量学分析。本研究旨在比较八边形多级场地测试(MFT)和“8字”改良测试(MFT-8)所获得的生理反应和表现。16名经过训练的轮椅篮球运动员在随机条件下完成了这两项测试。测量了完成测试的水平(测试结束时的分数)、摄氧量峰值(VO2peak)、分钟通气量(VEpeak)、心率(HRpeak)、峰值和相对血乳酸(Δ[Lact(-)] = 峰值 - 静息值)以及主观用力程度分级(RPE)。与MFT相比,MFT-8诱导出更高的VO2peak和VEpeak值(VO2peak:2.5±0.6对2.3±0.6 L·min(-1),VEpeak:96.3±29.1对86.6±23.4 L·min(-1);P<0.05),其他参数无差异。两项场地测试中,VEpeak与测试结束时的分数之间均存在显著相关性(P<0.05)。在力竭时,MFT未完全达到VO2peak和VEpeak。在有经验的轮椅运动员中,MFT-8对测试表现没有影响,但比MFT产生更高的生理反应。这可以通过改良条件下“8字”动作中轮椅技能的要求来解释。
