ABSTRACT
Researchers have extensively studied the biomechanics and anthropometrics of fast bowling in men's cricket, but there is still limited research in women's cricket. This study describes and compares the anthropometric qualities and bowling biomechanics between elite male and female fast bowlers. An inertial measurement system was used to collect three-dimensional biomechanical data for 20 elite fast bowlers (13 males and seven females). Kinematic data was captured at one step before back foot contact, back foot contact, front foot contact, ball release to one step after ball release. Anthropometric measurements included body segment lengths, mass, body fat (BF%) and muscle mass (MM%). The student t-test and Mann-Whitney U test were used for analyses. Hotelling's T2 statistic was calculated to control Type I error during multiple comparisons (p = 0.045). Males and females differed in overall height, limb length, BF% and MM%. Females presented with slower ball release speeds (p = 0.001). Biomechanically, the females were more front-on when approaching the delivery stride and then initiated pelvis and trunk rotation during the delivery stride, not seen in the males. Females and males have a similar magnitude of trunk side-flexion, but females present with a different strategy than males (p = 0.038). Females presented with increased front knee extension at ball release (p = 0.05). The findings from this study emphasise the differences between male and female fast bowlers and suggest that the coaching principles used in male fast bowling may not be relevant to female fast bowlers.
