The aim of this study was to identify the key aspects of technique that characterize the fastest bowlers. Kinematic data were collected for 20 elite male fast.
Here, as coaches we will be able to observe a bowler who has mastered the skill. When they go through the kinetic chain sequence, they can do it without thinking. They trust us to help them. They need to re-visit the kinetic chain sequence progression on a weekly basis. If each stage is mastered, the bowler moves on quickly. From experience, as a coach and as a player, coaches need to be aware that between stage 3 and 4 the bowler will get very frustrated.
They start thinking too much.
External factors interfere with their thinking. Loss of Rhythm and Confidence However, things can change very quickly in cricket.
They start doubting themselves and begin over-thinking their bowling action. External factors, like pressure or bowling at a certain batter starts to get them thinking too much and the results are so sad to see.
After this happens, the bowler would then unfortunately return to stage 1 or 2 and the long process begins again. They can then picture what they need to do without having to over-think the technical reasoning for it. Currently, our girls predominantly start at this stage. We only spend a year on this abbreviated drill before moving onto the progressive model as seen on the video clip. Within the initial drill, we are still mindful of the key points, such as feet alignment under hips, ball delivered above hip, chest lead, braced front leg and heel contact.
We have found this model effective. I fully appreciate technically drilling a bowling action is both tedious and a long-winded process, both for the player and the coach.
Technical reinforcement work has to be done. There is a need to understand how the individual processes the information and learns. Constraints During Skill Acquisition Coaches also need to be aware of the constraints that occur during skill acquisition.
The challenge for the coach is how to integrate the vast amounts of sport science information, difference of opinion and methods into their training and competition programmes. Constraints are not always limiting or negative factors. They are all the factors that influence learning and performance at any moment in time.
Constraints can refer to the organismic [individual], the environment and ultimately the task. The individual, environmental and task constraints all interact in order to determine the way that a performer completes a goal related task. Each influences how fast bowlers learn and acquire new skills. If the bowler has poor general strength levels, adding special strength training and weighted ball bowling to a bowlers program will serve no purpose.
Environmental constraints include both physical and social environmental factors. Physical factors include gravity, ambient temperature, natural light, terrain, auditory feedback or other environmental features that are not usually adaptations of the task.
These constraints could include cultural norms e. India produces great spin bowlers , as well as family support networks, peer groups, societal expectation e. For fast bowlers to develop in the UK and the county game, the wickets need to be improved. Currently, there are two types of wickets in the county game. There are either flat, unresponsive wickets or green top wickets.
One is too hard; the other takes little effort to be effective. This would be seen as environmental constraints. Skill acquisition is influenced by the environment our young bowlers learn in. Why bend your back and have a large flexion at the waist when actually you just have to put the ball in the right area? This is obviously a negative constraint in this instance. Finally, task constraints are factors that are usually more closely related to performance and include the rules of the sport, the coach themself, equipment used, pitch sizes and player numbers.
For example, is the limit on bowling one bouncer per over for our young quicks conducive to developing fast bowlers? Is T20 itself putting young quicks off from trying to bowl fast? All these are great examples of task constraints. We need to avoid bowlers fearing conceding runs or bowling wides because they might be dropped. I don't think you can teach it easily, because it's very precise.
There is no margin for error. They try to teach you growing up but most fast bowlers don't use their wrist, for instance, when throwing the ball.
They generate that whippy power mainly from their elbow. So it's hard to add the wrist to the bowling action as well. They haven't come up with a satisfactory technique yet to teach bowlers to use their wrist properly.
There are methods to strengthen the wrist, using weights, and that can help a little. Really, though, it's something you're born with. When I take off at the crease, leaving the ground, my wrist is cocked. When I get my arm back and it comes through nice and high, with my wrist in the perfect position to snap through the ball, that's when it feels right, when it really goes.
The accuracy comes with doing it day in and day out. It becomes second nature. When I'm bowling, I don't think about it. If you have to think about it, you'll struggle. If you get that part right subconsciously, you can concentrate then on different grips and angles, to put work on the ball, and make the ball work for you at the other end, cutting or swinging.
As for the bouncer, the fast bowler's ultimate weapon in many ways, you generally keep a little bit in reserve. You don't want to show the batsman too much. It's impossible to bowl at per cent effort all the time anyway. Jason [Gillespie], Glenn [McGrath] and myself, we probably bowl at or around the 90 per cent mark most of the time. You keep the other 10 per cent for the yorker or the really fast bouncer. It was at a stage when I felt really fit.
It was just one of those days, it was on a fast track, at the WACA, and everything clicked. My captain that day was Steve Waugh, who was also the Test captain obviously, so I was conscious of that too.
I just ran in all day and it felt good. Things really happened, all on one day. Unfortunately there was no speed camera there, but Steve and Mark Waugh and a few others all said they'd never seen anything quicker than that on that day.
The fastest I've been clocked at is That was in South Africa last year see table.
The second fastest was kph, which was over there again in It might be something in the air, and South Africa has been a pretty happy hunting ground for me. There's a lot of media hype about these speed-gun tests, which is fair enough and it's great for the kids, a bit of a show. But the more important thing is to get one type of speed-gun used across the board in match conditions.
It shouldn't matter if you're playing in South Africa or Sri Lanka, the measuring device should be the same - and that's not the case at the moment. In New Zealand, for instance, the speed gun is heaps slower. You feel like you're bowling at kph, and you look up at the board and it says you're bowling at kph.
You know it can't be right. I'll tell you this: Devon Malcolm is remarkable.
To be bowling consistently at more than 90 mph at 40 years if age is something else. If I'm still bowling at 40 it certainly won't be at 90 mph - and it will be a miracle if I'm bowling at all. Nearly all the Australian batsmen will tell you that the fastest bowling they have faced has been against Devon.
He was a bit of an idol of mine, and he's a real gentleman too. Not that you need to be to bowl fast.
But he is. As for the fastest I've seen, I never watched a lot of cricket growing up. It's only been in the past 10 years I suppose that I've gone back over the video-tapes to have a look at the likes of Lillee and Jeff Thomson. The first senior match I ever went to I was playing in. I was 12th man. Some people imagine that most Test players spent their childhood watching Test cricket, going to the grounds and getting autographs, but I have to tell you that wasn't the case with me.
I was born about an hour-and-a-half south of Sydney so I didn't get the opportunities to go to those matches anyway. We were always out playing in the back yard, me and my two brothers. So I never saw Thommo bowl live, for instance. I've watched a lot of footage of him, though, and I reckon he had the perfect action. Yet oddly enough, there's not a coach out there who has tried to get kids to bowl like Thommo did.
It's like an unwound coil, spitting the ball out from behind his back almost. But the most important thing about Thommo's action was that his shoulders and hips were virtually in the same line.
At some point in his action, his knuckles were all but touching the ground, because he's a very flexible athlete. I was talking to Allan Border about Thommo recently and he said that Jeff could probably still put his legs over the back of his head.
As for fast bowlers going easy on each other, as they reckon used to be the case some time, I don't think that's the case now. I hope not. That might sound stupid but I'd rather be taken seriously as a cricketer, even down the order. Over the past 10 to 15 years there has been this notion of a fast bowlers' union, with our lot agreeing not to bounce each other etc, but I like to play my cricket very hard.
If I've got a bat in my hand, they should treat me like a batsman, even if it's at 8, 9 or If that means copping a few bouncers, that's the way it is.
This is Test cricket, after all and you're playing for your country. I expect to get bounced - and I hope they expect to get bounced when they face me. They say fast bowlers aren't too bright. Well I always reply: who's the brightest, the guy bowling kph, or the guy facing him? Every Test-level fast bowler reaches speeds above 80mph so, no matter who you're facing, the ball is moving so fast that there's no time to think about what you're doing - you've just got to react to it.
Facing fast bowling is mentally demanding so a good temperament is vital. You can't fear the pace but you must respect it. Be prepared to take a few hits but don't let them ruffle you. It hurts when you get hit so get ready to wear a few bruises. You must stay positive, though.
I always think you should treat fast bowling as an opportunity to score runs by using the bowlers' pace to your own advantage. The quicker the ball comes onto the bat the quicker it will go off. Runs can come quickly, too, especially if the ball is new and there are gaps in the field. At the same time you need to be patient. Not every ball can be hit to the boundary. You have to accept that in almost every innings there will be periods where the bowlers will be on top.
When they are it's a matter of getting through the spell and staying calm. I keep my stance simple, standing on the line of the crease with my feet a comfortable width apart. My trigger movement is an initial small step forwards then, as the ball is released, a second small foot movement, only this time backwards towards my wicket. This provides a solid base from which I can react to the ball. The faster the ball, the more exaggerated my second backward movement becomes. It's an instinctive thing.
By getting onto my back foot I'm giving myself as much time as possible to react. It's only a fraction of a second extra but any time you can create helps.
