What does the term “About 90% of body weight should be over the front foot as the bowl is delivered” mean?
To simplify an example, imagine a bowler weighs 100 kg. Imagine that the mat is actually a platform scale. As the bowler stands on the ‘mat’, the scale reads 100kg. Now imagine that the bowler begins a delivery and steps forward, not onto the rink surface, but onto the platform of another scale. At the moment of bowl release, the original scale reading should drop from 100 kg to 10 kg, and the front scale should advance from 0 kg to 90 kg. If the bowler weighed 50 kg, the weight distribution should be about 45 kg (front) and 5 kg (back). The back foot should bear only sufficient weight to help steady the delivery posture. The significance of the term and the example is that insufficient advance of body weight is a common problem that can cause leg discomfort, inconsistent delivery speed and postural instability, any of which can lead to inaccurate performance.
