Lifting the lead leg aggressively to the chest (Photos 1-2) with as little change as possible in the sprinting posture will be sufficient enough to clear the hurdle.
The action of the hurdler over the hurdle (in the air) is indigenous to the sprinting off the hurdle that begins the sprint between hurdles.
A precise arm action is also critical in maintaining balance, control, rhythm, and speed in sprinting the hurdles.
Although the outer lane should give runners a biomechanical advantage when sprinting the curve portion of the track, the results are not apparent.
It would thus appear that further investigation is needed in determining the psychological effect of positioning (lane selection) in sprinting the curve portion of the track.
Dynamic, as opposed to static, stretching that simulates sprinting (skipping, high knees, rapid fire feet, etc.) will create a well-trained efficient neural pathway from the brain to the muscle.
Three types of energy conversions are important in sprinting, with each requiring a different approach to training (see box below).
As you can see, many training items can be used in achieving "sprinting shape." Coaches and athletes would do well to use them all, alternating "hard days" of all-out sprinting with "easy days" of drills, stretching, mechanics, non-speed training, weight training, etc.
