Abstract

Currently, there are no validated field-based measures of bat speed in cricket. This study sought to validate a baseball bat-mounted sensor for use in cricketers. Nine professional female cricketers (19.9 ± 2.8 years, 166.6 ± 4.8 cm, 68.7 ± 8.6 kg) performed 40 swings across four shot types (Cut, Drive, Pull, Slog-Sweep). Bat speed from a bat-mounted sensor was compared to optical motion capture (MoCap). Bat speed differed between shot types and ranged from 52.8 to 87.9 km/h. Device accuracy was determined by Bland-Altman bias and precision. The Drive shot had the smallest bias (-1.0 km/h; 1.4%), followed by the Slog-Sweep (2.0 km/h; 2.7%), Pull (2.0 km/h; 2.8%) then Cut shot, (2.5 km/h; 3.9%). The Cut shot had the greatest precision (2.7 km/h; 4.1%), followed by Pull (3.4 km/h; 4.7%), Slog-Sweep (4.0 km/h; 5.3%) and Drive (4.4 km/h; 6.3%). Kendall's tau analysis showed that proportional errors increased with higher bat speeds for all shots except Pull, (p < 0.05). The evidence supports use of the sensor for bat speed among female cricket players for all shots between speeds of 52.8-87.9 km/h. Caution is warranted for additional shot types, and speeds outside the explored range.

用于测量优秀女板球运动员球拍速度的蝙蝠安装传感器的准确性。

目前，在板球中还没有有效的基于场地的击球速度测量方法。这项研究试图验证一种安装在棒球棒上的传感器在板球运动员身上的应用。9名职业女板球运动员（年龄19.9±2.8岁，身高166.6±4.8厘米，体重68.7±8.6公斤）在四种击球类型（切球、扣球、拉球、扫球）中进行了40次击球。将安装在蝙蝠传感器上的蝙蝠速度与光学运动捕捉（MoCap）进行了比较。不同类型的击球速度不同，范围从52.8到87.9公里/小时。装置精度由Bland-Altman偏差和精密度决定。Drive射击的偏差最小（-1.0 km/h, 1.4%），其次是slogan - sweep射击（2.0 km/h, 2.7%）、Pull射击（2.0 km/h, 2.8%），然后是Cut射击（2.5 km/h, 3.9%）。Cut shot的精度最高（2.7 km/h, 4.1%），其次是Pull (3.4 km/h, 4.7%), logg - sweep （4.0 km/h, 5.3%）和Drive （4.4 km/h, 6.3%）。肯德尔的tau分析表明，除了拉球外，所有击球的比例误差都随着击球速度的增加而增加

期刊介绍： Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic). Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly. Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
