Nz under 19

The under 19 team did it again last night, beating Japan 90 - 10, with the CBHS boys well to the fore. The big one is against Australia on Friday. That will be on TV3 in NZ though at 2am.
I have been working on calculating on working out the power of the jumpers and lifters in the line out using the data I got from the U19 practices. The general figure appears to be a steady 2500W during lifting though a jumper can achieve this by himself in the short duration of take-off. The lifters together then maintain this power until the jumper reaches the peak of the jump. The timing of the lift is critical since the lift must be applied near the end of the jumper's take-off when the speed is maximum. Any later and the force needed to reaccelerate the jumper is substantially increased. Since the time spent at the top of the jump is relatively long and easy to maintain, an early jump is not as critical as a late jump. The throw is more critical as even a small error in speed or angle will cause the catch to be missed or the opposition to be able to intercept.Even if an early jump makes catching easier it allows the opposition to compete more successfully.
