COACHING : Basic Bowling #1

Building an action
First, the player must grip the ball in the correct fashion, index and middle finger on top of the ball, lightly resting the thumb underneath. The seam should be pointed straight down the wicket.
Second, is to get the player to stand with feet firmly planted on the ground. Thirdly, tuck the front elbow in beside the front hip and leave it there. Fourthly, with a straight arm above the head and with a flick of the wrist get the bowler to pass it 5meters on the full to their partner without bending their arm during delivery.
Following the development of a straight-arm and strong wrist flick, the next step is the gather and explode. From a standing start have the players, raise their front arm, lift the front leg and as they step forward with momentum using that momentum to deliver the ball.
Get your young bowlers to run through a passage of markers about 1.5m apart.

Here you may have to correct some players in correct running techniques, ensuring that they keep their elbows close to the body, pump the arms and have the legs pumping in the same target direction. Get your athletes to do this first with eyes open, then eyes closed, then with a cricket ball in their hands.
The aim of this exercise is to get all the bowler’s energy and momentum traveling through the target channel everything working together for the same goal. A straight run-up increases maximum energy transfer (speed) onto the ball. Bowlers should gradually build up to their maximum running speed as they are entering the delivery stride. Force = Mass x Acceleration. Therefore a pace bowlers force (or speed) imparted to the ball is directly equal to the amount of Mass (weight with momentum towards target channel) multiplied by the Acceleration (timing of run-up to maximum speed at delivery stride).
Suggested progression building a bowling action.
1. Stationary bowling
2. Walk up and bowl
3. Target Channel running.
4. Jog up and bowl
5. ½ run up and bowl
6. Full run up and bowl
7. Line and Length practice (good areas)
8. Competitive situation against batsman

13 4. Basic Bowling
Technique specific
Feet Alignment – all steps have to land close to one line parallel to the target channel
• Use channels to dictate where the feet should initially land (markers, tape, chalk)
• Use channels for drill work until feet alignment competent
• Progress to using less visual aids

Front Arm Pathway
• Thumb up past nose
• Thumb brushing peak of cap
• One eyed view at the target (looking through the front arm)

Gather & Explode
• Raise front arm up
• Place ball under chin, or out in front but always high.
• Land on front braced leg
• Pull down elbow of front arm into the hip (shaking hands)
• Follow through hard with full rotation of shoulders
• Bring back hip over front leg
• Bowling arm should be a vertical pathway

Pace bowling
True fast bowlers are an important asset for any cricket team. If a player shows an ability to bowl the ball quickly, he is strong and has a correct technique, that player should be encouraged to bowl in short, fast spells. Do not forsake pace for line and length, the players should be encouraged to bowl `good areas’ at top pace.
Fast bowling is a demanding exercise and bowlers should be encouraged to warm up for at least 10 minutes and to stretch whenever possible, especially at the beginning and end of activity. Coaches should be aware of the value of a true fast bowler and look after them accordingly.
Coaches must be able to distinguish bowling from throwing, `chucking’ motion. If identified as a problem in a player, coaches should take steps to change this. This is set out in ICC Law 24.3 – No ball.
LAW 24.3 No ball
3. Definition of fair delivery – the arm A ball is fairly delivered in respect of the arm if, once the bowler's arm has reached the level of the shoulder in the delivery swing, the elbow joint is not straightened partially or completely from that point until the ball has left the hand. This definition shall not debar a bowler from flexing or rotating the wrist in the delivery swing.
Spin bowling
14 4. Basic Bowling
When looking to bowl spin two things are paramount. That the ball is `spun hard’ (i.e. maximum revolutions imparted on the ball) and the ball is looped (Thrown above the batsman’s eyes and landing in front of the batsman).
A young spin bowler needs more encouragement than most. With small hands, accuracy is always going to be a problem for the young bowler. He should be encouraged to spin the ball as hard as he can and flight (`loop’) the ball above the batsman’s eyes. To help achieve maximum spin it is important that the bowler has great body rotation. So he uses his body in this order to achieve maximum revolutions on the ball, body side-on pivoting on the toes of his front foot so that his waist then shoulders, then wrist then fingers all rotate to apply maximum force to the ball.
