Given the intermittent nature of basketball and the different demands that occur during playing time that are specific to every level of competition, the ratio of accelerations/decelerations and the intensity level across quarters were evaluated in female elite junior basketball players (n = 48; age: 16.8 ± 0.7 years; height: 1.76 ± 0.07 cm; body mass: 67.2 ± 6.2 kg). The following variables were analyzed to determine physical persistency across game quarters:(a) total distance covered (m), (b) high-intensity running (HIR) (14-21 km·h) distance covered (m), (c) sprint (21-30 km·h) distance covered (m), (d) total accelerations (n), (e) total decelerations (n), (f) relative accelerations (n·min), (g) relative decelerations (n·min), (h) ratio of acceleration/deceleration (A/D), (i) total jumps (j) relative jumps (n·min) (k) player load (AU). using the WIMU PRO system. Higher but shorter acceleration intensity occurred during the last quarters due to the tight results of the matches. The results suggest that high-intensity efforts such as sprints and HIR seem to increase the A/D ratio (guard and forward positions). Therefore, specific conditioning, as well as eccentric strength training, could be included by practitioners in training programs to improve the performance of these positions during competition, especially as a prior preparation to a game-congested event. Centers seem to have a more variable performance through quarters than do other positions, perhaps highlighting the need for specific conditioning strategies.
鉴于篮球运动的间歇性特点,以及在不同比赛级别中特定于每个比赛阶段的不同运动需求,本研究评估了女性精英青少年篮球运动员(n = 48;年龄:16.8 ± 0.7 岁;身高:1.76 ± 0.07 cm;体重:67.2 ± 6.2 kg)的加速/减速比和各节比赛的强度水平。为了确定各节比赛中球员的身体持续性,分析了以下变量:(a)总跑动距离(m),(b)高强度跑动(HIR)(14-21 km·h)跑动距离(m),(c)冲刺(21-30 km·h)跑动距离(m),(d)总加速次数(n),(e)总减速次数(n),(f)相对加速次数(n·min),(g)相对减速次数(n·min),(h)加速/减速比(A/D),(i)总跳跃次数(j)相对跳跃次数(n·min)(k)球员负荷(AU)。使用 WIMU PRO 系统进行测量。由于比赛结果紧张,最后几节的加速强度更高,但持续时间更短。结果表明,高强度的努力,如冲刺和 HIR,似乎会增加 A/D 比(后卫和前锋位置)。因此,教练可以在训练计划中纳入特定的体能训练和离心力量训练,以提高这些位置在比赛中的表现,尤其是作为比赛密集期的赛前准备。与其他位置相比,中锋在各节比赛中的表现似乎更为多变,这或许突出了特定体能训练策略的必要性。
