Jackanory,
Maybe I'm unusual, but I often get the impression that a lot of people are just arguing different things.
I think HRE is saying something different. Of course training has evolved. Even Lydiard training has evolved from the pure linear periodization that gets so heavily criticized. As we mentioned before, Lydiard himself proposed other alternatives to maintain the aerobic/anaerobic balance and still peak when desired.
But guess what, many other things have evolved in parallel:
- Knowledge of physiology has evolved
- Technology of running accessories, e.g. clothes, shoes, gadgets, drinks, gels, etc.
- Diet and nutrition have evolved
- The sport has evolved from amateurism towards professionalism
- The profile of the top athletes has evolved from Western to Eastern African (Kenyans tend to be smaller and lighter in spite of generations getting larger)
- The mentality of athletes has evolved
- Running surfaces have evolved
- Times have evolved, making the impossible seem possible
- Unfortunately drugs have evolved (e.g. blood doping -> EPO -> CERA -> microdosing EPO), and fortunately drug testing has evolved
- Incentives for racing events has evolved
- Marathon racing has evolved recently due to the lack of 10K races
- ...
Just as training hasn't stopped evolving, so the rest of the world evolves as it revolves. To claim that changes in training methodology are the absolute unique sole cause of the improvements in times, is to deny the evolution of the many other facets related to racing as possibly also contributing to the improvements. HRE isn't so much denying evolution of training, as saying that it's not the only thing, and it's hard to quantify the effect of each individual contribution. Some may be zero (e.g. both Lydiard and Canova don't dope) or even negative, but there is always the chance that one or more of these alternatives have contributed positively. Training may be the biggest contribution, but it also may not be possible to apply this training to the Western athletes of today.
I suggested one way to help eliminate many of these variables, short of proving anything with a complete battery of large scale long term controlled studies, is for Renato to train an Italian (or Antonio to train a Portuguese) to hang with Moses, or alternative, have Nobby or Lorraine Mollar, or HRE, or Ken Livingstone train a Kenyan (or Japanese or American) to hang with Moses, or maybe we will have to wait for gypsy to Soviet train 56 Juniors to a long term career that rivals Carlos Lopes or Haile Gebresselassie.
I don't think HRE meant to accuse or insult Renato, but that seems to have backfired in a big way. gypsy was certainly more direct with his comments, while HRE was just saying there are still many other possibilities which can not be ruled out or ignored.
You mention slow twitch and fast twitch fibers requiring different training, but this was not a distinction lost on Lydiard. He recognized that there were speed types and endurance types. But an important part of training is observing the athletes response to training, and adapting the plan. In this way, there is little risk under Lydiard of giving athletes the same training, especially in the later "less generic" phases, even if the plans are initially the same.
