Spencer, KN, Paget, N, Farley, ORL, and Kilding, AE. Activity profile of elite netball umpires during match play. J Strength Cond Res 34(10): 2832-2839, 2020-The study aimed to determine activity profiles of officials in elite netball. Physical demands of Load·min (au) representing accumulated accelerations by triaxial accelerometers during matches and exercise-to-rest ratio were measured using global positioning systems (Catapult, MinimaxX S4). Physiological demands were quantified by estimated equivalent distance and heart rate (HR) (MeanHR, percentage HRpeak, and HRzones) and movement variables (frequency, mean time, and percentage of total time) were coded using Sportscode Elite (Version 10, Hudl, Lincoln, Nebraska). Differences were analyzed by periods (Q1-Q4). Load·min (au) (M = 407 ± 66) significantly varied with time (F [3, 55] = 3.42, p = 0.02) and the highest percentage of exercise-to-rest performed in Q1 (21 ± 5%). Estimated equivalent distance (3,839 ± 614 m) varied significantly with time (F [3, 56] = 3.18, p = 0.03), the umpires spent longest duration of time (35%) in HRzone 3 (75-85% of HRpeak). Mean HR significantly decreased with time (p < 0.01; Q1 [157 ± 13], quarter 2 [156 ± 12], and Q4 [153 ± 14]). Umpires spent 77% in rest-recovery ratio movements and 23% of time exercise-to-rest ratio. In summary, netball umpiring is characterized by intermittent, short, high-intensity activity (sprinting, sidestepping, and turn to change direction), with increasing periods of rest-recovery (walking and standing).
斯宾塞、KN、佩奇、N、法利、ORL 和基尔丁，AE。精英无挡板篮球裁判员在比赛中的活动特征。J 力量与调理研究 34（10）：2832-2839，2020-本研究旨在确定精英无挡板篮球裁判员的活动特征。使用全球定位系统（Catapult，MinimaxX S4）测量了负载·min（au）（代表三轴加速度计在比赛中积累的加速度）和运动与休息的比值。生理需求通过估计等效距离和心率（HR）（MeanHR、HRpeak 的百分比和 HRzones）进行量化，运动变量（频率、平均时间和总时间的百分比）使用 Sportscode Elite（版本 10，Hudl，Lincoln，Nebraska）进行编码。通过时期（Q1-Q4）进行分析差异。负载·min（au）（M=407±66）随时间显著变化（F[3，55]=3.42，p=0.02），运动与休息的最高百分比在 Q1 中进行（21±5%）。估计的等效距离（3839±614 m）随时间显著变化（F[3，56]=3.18，p=0.03），裁判员在 HRzone 3（HRpeak 的 75-85%）中花费最长的时间（35%）。Mean HR 随时间显著降低（p<0.01；Q1[157±13]，第 2 季度[156±12]，第 4 季度[153±14]）。裁判员的休息-恢复比运动占 77%，运动-休息比运动占 23%。总之，无挡板篮球裁判的特点是间歇性、短时间、高强度的活动（短跑、侧身、转身改变方向），休息-恢复的时间增加（步行和站立）。
