There is quite a bit of dissent in the ranks regarding Loughborough, in particular from Ian Pont. Pont believes you can get extra speed out of analysing an action and using physics. He also believes, in stark contrast to the Loughborough approach, that strength and conditioning training is damaging to a fast bowler, that the thing you need to do to get fit to bowl is to bowl. I'm totally with him on this second bit - unnecessary muscle mass just slows you down and makes you more prone to injury - look at someone like Shane Watson. Fitness is activity-specific. Malcolm Marshall used to prepare for the new season by running to get his cardiovascular fitness up. Then he'd bowl. And, um, that's it.
I'm also not convinced that investing in dedicated elite institutions is the best way to produce top players. The most important thing in producing top players is having as many youngsters as possible playing the game for fun.
