Like Youngy has said, there is no point in saying that Bradley/Youngy can’t produce sub 10.2x sprinters like S Franics/Mills/Smith, because we all know that genetics play a role in who gets to the start line in the Oly/WC Finals (The last Caucasian runner to make the Olympic Final was Wells 1980 (Bradley Trained), WC Final – Finnish runner Matic Osovnikar in 2005). There’s only a handful of Aussie runners who have run inside 10.20 and as Youngy has suggested, these runners often get pawned off to the institute coaches for ‘expert’ training.
It would be interesting to say the least if the current crop of elite Aussie sprinters took on JB methodology of training!
This history of the Bradley program suggests they completed this type of training since the poor weather conditions outside prevented them from training (rain/snow in the Scottish winter) and therefore JB devised a methodology which would strengthen and condition his athletes to be physically superior to other squads once the track preparation begun. The training is systematic and demanding and many on the ‘outside’ see it as a foolish method of training, however like Youngy says, those who knock the program have generally not participated in it or not followed it correctly, and therefore have not received the rewards on the track.
I don’t think it’s that established runners flock to JB or Youngy due to the success they have had or having, i think it’s more that runners on the outside look at the success these programs have, and the lack of success THEY are currently experiencing, and make a choice to move to one of these squads to learn another training method. Usually, these athletes have been under-achieving with their current coach or training group for several seasons on end, and then once put into a training environment which is systematic, brutal and physically demanding, they tend to fulfil some or if not all of their potential once the season starts.
Many ‘knockers’ choose not to embrace the JB program due the fact that science hasn’t endorsed ‘hitting a speedball’ and doing ‘bodyweight circuits’, but i would suspect if someone did conduct a study some of the findings which would result would include:
Increased Anaerobic Threshold
Increased VO2 Max
Increased Capillarisation
Fibre Type Transition
Increased Power Output
Increased Lean Muscle Mass
Decreased BF %
Increased RFD
Now, none of these are training adaptations which cannot be achieved through other training means, however i have seen them occur through the JB method and just because they haven’t been measured doesn’t mean they don’t occur.
Youngy’s results in South Australia speak for themselves!
and running slow so they score a better mark.
