Batting success in cricket relates more strongly to looming-related information than ball velocity: evidence from a Bayesian hierarchical model
摘要
This study examined how two ball-related kinematic parameters—looming rate and ball velocity—relate to cricket batting performance under binocular and monocular viewing conditions, and whether their relative contributions differ across the ball’s flight. We aimed to identify which source of visual information is more strongly associated with successful interception.
MethodsTwenty-two male batsmen (median age: 20 years; training experience of 5 years[IQR 3–7]) with best-corrected visual acuity ≤ 0.00 logMAR and stereopsis ≤ 40 arcsec faced 30 balls per condition under binocular(OU), right-eye(OD), and left-eye(OS) viewing during outdoor net practice. Ball trajectories were recorded from three camera views (30 fps), and custom video analysis was used to extract ball velocity (km/h) and looming rate (cm/s). Hit probability (hit/miss) was analysed using Bayesian hierarchical logistic regression with a single-window model and a phase-specific model separating pre-bounce velocity and post-bounce looming.
ResultsBatting performance was higher under OU (median hit rate 86.88% [IQR 83.93–93.93%]) than OD (78.57% [75–82.76%]) and OS viewing (80.00% [72.86–83.47%]). In the single-window model, looming rate showed a positive association with hit probability in OU (posterior mean: 0.14) and OD (0.42), but weakly negative in OS (− 0.18), whereas velocity showed negative associations across conditions. In the phase-specific model, post-bounce looming rate (0.30) showed a stronger association with hit probability than pre-bounce velocity (− 0.09).
ConclusionThese findings indicate that looming-related information shows a stronger association with successful interception than ball velocity, with binocular viewing supporting optimal cue use and limited compensation under monocular viewing.
