New School and Old School in the pros-a history
Old school: Lots of long slow miles, often for 7-8 hours almost every day and very little intensity during the winter. As racing season approaches there are still many long rides but including some more or less random periods of higher intensity, often on hills or when the person felt like it. Lots of what was called "racing into shape" where racing provided much of the intensity received during the weeks. Closer to peak there were more hard periods in training but mostly it was just more racing exposure to intensity.
New School: Started around the mid 80's. A team of neo-pros from America and Canada sponsored by 7-11 was training with an approach that included lots of specific intervals in their daily rides, not many rides beyond 6 hours, fairly strict structure for the intensity they sought during early-season races and performed during training.
Most days the team members would be divided up into small groups that would each have slightly different training objectives for the day. This was in contrast to the old school teams that would generally do one ride together for all team members or allow riders to do their own training.
Old school teams employed doctors/trainers that were usually family doctors that were so in love with cycling that they would take vacation from their practice for the opportunity to work alongside their heros for a few months or longer.
7-11, and a few new school teams in Europe employed a young group of doctors who had degrees in Sports Medicine. Among this group of doctors were Dr. Max Testa who was the team doctor for 7-11, and Dr. Michele Ferrari who was employed by an Italian team. The education and training of this group of doctors played the major role in how the new school teams planned, performed, and evaluated their training, and treated and prevented injuries. The new school teams also made use of various lab tests to measure fitness and response to some types of training and the 7-11 team was among the very first teams to use heart rate monitors.
When the 7-11 guys first went to Europe to play on the big stage they were the butt of jokes related to their tactics and training methods, and just the fact that they were an _American_ team in a European sport. It wasn't long before they won a few races here and there and more respect came when the 7-11 guys won some stages in the Tour de France with Alex Steida wearing the yellow jersey, and Jeff Pierce won the final stage into Paris with a rare solo breakaway. Full verification came when the American team, with Andy Hampsten won the Giro d' Italia.
Among the riders on the 7-11 team were, Bob Roll, Alexei Grewel, Chris Carmichael, Eric Heiden, Alex Stieda, Jeff Pierce, Raul Alcala, Davis Phinney, Doug Shapiro and Ron Kieffel.
