Fast-bowling knowledge lab
Evidence-aware guides to filming, measuring and interpreting a fast-bowling action with an ordinary phone camera.
Published · Updated
Start with the question you have
Filming
How to film your fast-bowling action
Where to put the phone, which camera settings to use and why 120 frames per second matters, for a clip a coach or an analysis app can review frame by frame.
Pace
How to bowl faster: what the research says
What studies of fast bowlers have and have not linked to ball speed, from run-up and front leg to strength, and how to use that without chasing one number.
Limitations
Can a phone measure your bowling speed?
How to time a delivery from slow-motion video, why the answer is lower and less precise than a speed gun's, and when a phone estimate is still useful.
Biomechanics
Front-knee brace in fast bowling
What front-knee brace means, when it is measured and why a single knee-angle number never tells the whole story.
Biomechanics
Trunk lean at release
How forward and lateral trunk position are described at release, and what a side-on phone camera can measure responsibly.
Consistency
Release-point consistency
A guide to comparing release positions across deliveries without mistaking camera movement for a change in technique.
Limitations
Can a phone check whether a bowling action is legal?
Why an ordinary phone video can support coaching but cannot replace an official three-dimensional bowling-action assessment.
