Thanks for this lecture.. I am very much intrested in this subject.. Can you explain me which factor of our body decide our bowling action, specifically our backfoot landing.
Hi Stuart, I saw the video repeatedly to understand the concepts as I have limited knowledge of science, especially physics. My question is, given the objective of scoring runs preferably clearing the ropes (six), given the angle, location, x factor at play and other factors like the speed of the bat etc, can we work backwards to figure out what is the correct body movement to get the optimum results. That is - for a given ball - what should be the size of the stride, what should be the x factor, elbow extension, wrist extension etc? Once we have it, we can actually map the movement of a player to see the variance between the two. Possible? Or is it already being done?
15:13 can’t wrap my head around this. Is the line coming perpendicular to both thorax and pelvis?. For practical purposes, how is this angle created? By moving your hips and shoulders in opposite direction?. For example, if a batter before ball is delivered stands in a way that his hips are somewhat horizontal (ie in the direction of the cricket stumps, while his shoulders are in one line facing the bowler, ie side on. This would result a slight twist in back but is this what you are referring to the X factor?” Theoretically, would changing the batting stance in a way that hips are facing the leg side boundary and shoulders facing the bowler before ball is delivered generate more power?. Thank you for the informative content you produce.
Hi. If standing upright, shoulders are likely over hips and so very little separation. Rotating torso but 'leaving hips behind' would cause an X or separation. You're right that stance may affect the starting separation but remember that is is the separation at the top of the backswing or how much of a stretch we create during the backswing that is important.
The Optimum launch angle says only the ball angle w.r.t its own plane (above the ground),not the bat angle ? When bat angle is said how we measure that? If it is a straight bat hit
The bat angle is also measured relative to the pitch. In that specific case, we would have been looking at the angle of the bat face about the global medio-lateral axis (i.e. bat pointing down at the ground, pointing back behind, pointing forwards, or what angle in-between) so that this could then be related to the launch angle you mention. Full details of all methods are in the published journal articles, all of which should be free to access in some format. I believe there are links somewhere in the video description.
29:55 Is there an explanation for why highly skilled players (HS) had a higher accuracy with occlusion pre-bounce than without occlusion? Does it have anything to do with heightened attentiveness of players? Or is it due to the way occlusion is implemented in this experiment?
Yeah, unfortunately a product of a poor WiFi connection during a live stream during COVID lockdown. Paul Felton's bowling lecture was streamed on the same day and has the same issue. Let me know if anything unclear as I have the original slides still.
I would argue that technique is more important than strength alone, but yes the same 'technique' performed with greater force-production capabilities is likely to result in grdater bat speed and so grdater ball carry distance if it can be timed effectively.
@@biomechstu sir one last question..do strong muscles help in achieving quicker bat speed? And if 2 persons have same bat speed and technique but different body strength will it effect six distance anyways?
If technique, timing, etc. are appropriate then strength is likely to positively effect bat speed. But if bat speed is the same then strength wouldn't effect the ball outcome, as strength can only have an influence through the bat
Ball distance is a result of bat speed, bat angle, and bat-ball impact location (e.g. sweet spot). Better values for one (e.g., bat speed due to strength) can compensate for suboptimal values in the others as long as the others still remain acceptable and not completely the wrong bat angle or missing the ball, etc.
Hi. I'm currently involved in editing a biomechanics book that will have a chapter on cricket, which will be available as a standalone document as well. Not published yet, though.
@@biomechstu yes sir very useful its always better to know what actually we are doing when we bowl. Your results, suggestions,techniques helps us to understand game better
