The purpose of this study was to examine performance advantages associated with batting stance, in the form of left- vs. right-handed dominant stance, and orthodox vs. reverse stance, of talented junior cricket batters within age-restricted competitions. Data were sourced from the national male younger age competition (YAC; Under-17; = 237) and older age competition (OAC; Under-19; = 302), as well as female YAC (Under-15; = 234) and OAC (Under-18; = 260) over a 4-year period. Left-hand dominant (LHD) batters were consistently overrepresented in the male YAC (Right: 69.2%; Left: 30.8%) and OAC (Right: 68.2%; Left: 31.8%) compared with the expected general population distribution. Male LHD batters exhibited a significantly ( < 0.05) higher batting aggregate (YAC: 116.82 ± 84.75 vs. 137.84 ± 89.74; OAC: 117.07 ± 89.00 vs. 146.28 ± 95.99), scored more runs (YAC: 19.65 ± 12.32 vs. 23.96 ± 14.71; OAC: 19.27 ± 12.61 vs. 23.98 ± 14.15), spent more time batting (YAC: 45.33 ± 25.89 min vs. 54.59 ± 28.62 min; OAC: 39.80 ± 21.79 min vs. 49.33 ± 27.41 min), and scored more boundary-4s per game (YAC: 1.83 ± 1.40 vs. 2.44 ± 1.87; OAC: 1.76 ± 1.32 vs. 2.19 ± 1.83), across both YAC and OAC groups with small effect sizes. No overrepresentation was present for either female group (YAC, Right: 88.5%/Left: 11.5%; OAC, Right: 90.0%/Left: 10.0%). Female LHD batters exhibited significantly higher batting aggregate (68.97 ± 53.17 vs. 102.96 ± 73.48), batting average (13.24 ± 10.88 vs. 17.75 ± 12.28), and spent more time batting per game (25.52 ± 15.08 vs. 37.75 ± 26.76 min), but only at the OAC level with small-moderate effects sizes. Finally, there were few performance advantages identified to batting with a reverse stance, with further work needed to clarify any potential biomechanical benefits. Team selection practices may exploit the left-handed advantage by over-selecting talented left-handed junior cricketers. Practical implications for coaches include creating practice environments that negate the negative frequency-dependent selection, such as providing more practice opportunities for their players against left-handed opponents.
本研究的目的是考察在年龄受限的比赛中，有天赋的青少年板球击球手的击球姿势（以左手与右手主导姿势、正统姿势与反向姿势的形式）所带来的表现优势。数据来源于全国男子青年年龄组比赛（YAC；17岁以下；n = 237）和老年年龄组比赛（OAC；19岁以下；n = 302），以及女子YAC（15岁以下；n = 234）和OAC（18岁以下；n = 260），为期4年。与预期的总体人群分布相比，左手主导（LHD）击球手在男子YAC（右手：69.2%；左手：30.8%）和OAC（右手：68.2%；左手：31.8%）中一直占比过高。在YAC和OAC两个组中，男子LHD击球手的击球总成绩显著更高（YAC：116.82±84.75对137.84±89.74；OAC：117.07±89.00对146.28±95.99），得分更多（YAC：19.65±12.32对23.96±14.71；OAC：19.27±12.61对23.98±14.15），击球时间更长（YAC：45.33±25.89分钟对54.59±28.62分钟；OAC：39.80±21.79分钟对49.33±27.41分钟），且每场比赛的四分边界得分更多（YAC：1.83±1.40对2.44±1.87；OAC：1.76±1.32对2.19±1.83），效应量较小。两个女子组均未出现占比过高的情况（YAC，右手：88.5%/左手：11.5%；OAC，右手：90.0%/左手：10.0%）。女子LHD击球手的击球总成绩显著更高（68.97±53.17对102.96±73.48），击球平均得分更高（13.24±10.88对17.75±12.28），且每场比赛的击球时间更长（25.52±15.08对37.75±26.76分钟），但仅在OAC水平上有小到中等的效应量。最后，几乎没有发现反向姿势击球的表现优势，需要进一步开展工作来阐明任何潜在的生物力学益处。球队选拔做法可能会通过过度选拔有天赋的左手青少年板球运动员来利用左手优势。对教练的实际启示包括营造能够消除负频率依赖选拔的训练环境，比如为球员提供更多与左手对手比赛的训练机会。
