Running Anaerobic Sprint Test (RAST) as a hyperlactatemia inductor, short distances (specific distance, 20 m) during progressive intensity and mathematical analysis to interpret aerobic and anaerobic variables. The basketball players were assigned to four groups: All positions (n=26), Guard (n= 7), Forward (n=11) and Center (n=8). The hyperlactatemia elevation (RAST) method consisted of 6 maximum sprints over 35 m separated by 10 s of recovery. The progressive phase of the lactate minimum test consisted of 5 stages controlled by an electronic metronome (8.0, 9.0, 10.0, 11.0 and 12.0 km/h) over a 20 m distance. The RAST variables and the lactate values were analyzed using visual and mathematical models. The intensity of the lactate minimum test, determined by a visual method, reduced in relation to polynomial fits (2nd degree) for the Small Forward positions and General groups. The Power and Fatigue Index values, determined by both methods, visual and 3rd degree polynomial, were not significantly different between the groups. In conclusion, the RAST is an excellent hyperlactatemia inductor and the progressive intensity of lactate minimum test using short distances (20 m) can be specifically used to evaluate the aerobic capacity of basketball players. In addition, no differences were observed between the visual and polynomial methods for RAST variables, but lactate minimum intensity was influenced by the method of analysis.
本研究的目的是为精英篮球运动员提出一项特定的乳酸最低测试,该测试考虑以下因素:将跑步无氧冲刺测试(RAST)作为高乳酸血症诱导剂,在递增强度下设置短距离(特定距离为20米),并进行数学分析以解释有氧和无氧变量。篮球运动员被分为四组:所有位置(n = 26)、后卫(n = 7)、前锋(n = 11)和中锋(n = 8)。高乳酸血症升高(RAST)方法包括在35米距离内进行6次最大冲刺,每次冲刺间隔10秒恢复时间。乳酸最低测试的递增阶段包括在20米距离内由电子节拍器控制的5个阶段(8.0、9.0、10.0、11.0和12.0公里/小时)。使用视觉和数学模型分析RAST变量和乳酸值。通过视觉方法确定的乳酸最低测试强度,相对于小前锋位置和一般组的二次多项式拟合有所降低。通过视觉和三次多项式两种方法确定的功率和疲劳指数值在各组之间没有显著差异。总之,RAST是一种出色的高乳酸血症诱导剂,使用短距离(20米)的乳酸最低测试的递增强度可专门用于评估篮球运动员的有氧能力。此外,对于RAST变量,视觉方法和多项式方法之间未观察到差异,但乳酸最低强度受分析方法的影响。
