How to calculate a curved 8 stride high jump run-up for the flop technique.
1 Curve length
2 Take-off position
3 Take-off angle
Are all important in a good run-up. This video shows how to measure the average curve thength. Then using the calculation programme the correct dimensions can be measure and marked out.
Using the Excel file change the numbers in the red boxes. Use the technique in the video to measure straight and curve length. A good take-off angle is 30 – 35 degrees, below 30 increases the risk of medial ankle injury. The take-off position depends on run-up speed and the bar height. Higher speeds (7.5 m/s +) and bars (2.20m +) require a take-off position over 1m out from the bar (position ‘y’)and less than 30cm from the end of the bar (position ‘x’). Junior jumpers should practice jumping from approx. x = 0,35m y = 0, 70m. This position should be decided by a high jump coach or using video analysis.
The resulting figures are the measurement where the run-up markers should be placed to visually guide the athlete through the predetermined and practiced run-up.
