The study aims to provide a morphological profile of Indian cricketers and find physiological demands and positional differences of the batsmen in T20 matches according to their batting order. Eighty-three male cricketers (age: 17.93 ± 2.23 years) participated in this study and categorized into upper-order ( = 36), middle-order ( = 35) and lower-order ( = 12) batsmen. Height, weight, body fat%, and somatotype were measured. Movement analysis and heart rate (HR) responses were recorded during batting in T20 matches using PolarV800 smart-watch and H7 HR sensor. Descriptive statistics, one-way ANOVA followed by post-hoc analysis examined group differences. Results indicated that upper-order batsmen were balanced mesomorph, middle-order batsmen were mesomorphic-endomorph, and lower-order batsmen were mesomorphic-ectomorph. Cricket-specific movement patterns showed that standing made-up the majority of time spent (54.1 - 60.9%), while maximum distance was covered by walking (68.5 - 73.3%) during batting. Lower-order batsmen spent significantly lesser time ( < 0.01; = 1.02) in the crease and covered lesser total distance ( < 0.05; = 0.85) compared to upper and middle-order batsmen, respectively. Upper-order batsmen maintained a significantly lower average HR throughout batting compared to middle ( < 0.01; = 1.07) and lower-order ( < 0.01; = 2.04) batsmen. Moreover, upper-order batsmen spent significantly more time in the low-intensity target HR (THR) zone (9.9%) compared to the middle (3.2%; < 0.01; = 0.72) and lower-order (~2.3%; < 0.05; = 0.69). Additionally, upper-order batsmen spent significantly less time (20.8%; < 0.01) in the high-intensity THR compared to the middle (55.3%) and lower-order (52.2%) batsmen. Therefore, the findings highlight distinct movement and physiological demands associated with batting at different orders during T20 matches, which conditioning coaches and cricketers can utilize to optimize training programs and enhance individual performance.
该研究旨在提供印度板球运动员的形态特征，并根据击球顺序找出20 Twenty（T20）比赛中击球手的生理需求和位置差异。83名男性板球运动员（年龄：17.93±2.23岁）参与了本研究，并被分为前场击球手（n = 36）、中场击球手（n = 35）和后场击球手（n = 12）。测量了身高、体重、体脂百分比和体型。使用PolarV800智能手表和H7心率传感器在T20比赛击球过程中记录运动分析和心率（HR）反应。采用描述性统计、单因素方差分析及事后分析来检验组间差异。结果表明，前场击球手为均衡的中胚层体型，中场击球手为中胚层-内胚层体型，后场击球手为中胚层-外胚层体型。特定于板球的运动模式表明，站立占击球过程中花费时间的大部分（54.1 - 60.9%），而击球过程中行走覆盖的距离最长（68.5 - 73.3%）。与前场和中场击球手相比，后场击球手在击球区花费的时间显著更少（p < 0.01；d = 1.02），且覆盖的总距离更少（p < 0.05；d = 0.85）。与中场（p < 0.01；d = 1.07）和后场（p < 0.01；d = 2.04）击球手相比，前场击球手在整个击球过程中保持的平均心率显著更低。此外，与中场（约3.2%；p < 0.01；d = 0.72）和后场（约2.3%；p < 0.05；d = 0.69）击球手相比，前场击球手在低强度目标心率（THR）区花费的时间显著更多（约9.9%）。此外，与中场（55.3%）和后场（52.2%）击球手相比，前场击球手在高强度THR区花费的时间显著更少（20.8%；p < 0.01）。因此，研究结果突出了T20比赛中不同击球顺序所涉及的独特运动和生理需求，体能教练和板球运动员可利用这些需求来优化训练计划并提高个人表现。
