Comparison of ball and foot positioning of tenpin bowlers of various skill level during delivery.
Conference Contribution ResearchOnline@JCUAbstract
In tenpin bowling, the aim of each game is to knock down all ten pins using a bowling ball. If achieved with a single delivery it is termed a strike. If not achieved, a second ball may be used to knock down the remaining pins and if successful this results in a spare. It is generally accepted the best way to achieve a strike is for the ball to contact the ten pins at an area known as the pocket. Skilled bowlers generally deliver the ball by sliding towards the foul line while swinging the ball close to the slide foot. The slide foot is typically contra-lateral to the bowling arm (left foot for right handed bowlers). During the delivery phase, the minimum distance between the ball and slide foot malleolus in the frontal plane is referred to as spread. Whilst it is generally accepted spread should be minimised, spread has not been nvestigated. In addition, no previous studies have investigated ball positioning relative to the slide foot within the sagittal plane during delivery. The aim of this investigative study was to assess spread during the delivery phase and sagittal plane ball positioning upon release, for bowlers of various skill level.
