Over-training explained
Norwegian Ola Rønsen writes in his doctor's degree dissertation that training twice a day leads to stress for the athlete. He has studied the bodily reactions after two sets of hard training on the same day. The result of the study is that the second effort wears the body more than the first, even if the intensity had been the same.
"One hour in the morning and one in the afternoon is not the same as two hours in a row, and there is no 1+1=3 effect as sometimes believed", the Norwegian told his local paper, Romerikes Blad.
The tests were done by the national teams in speed skating and biathlon. They show that hormone and energy balance are more stressed by the second training of the day. The results are related to the variations in restitution time between the efforts.
"It's all logical, but hasn't been proved before. For these athletes a second training in the afternoon is necessary but it is important to find the right the right balance of restitution and training intensity. The classic case of over training is suddenly easy to explain."
R¿nsen was team physician for the Norwegian national cross country ski team some years ago and it was then he noticed the effect of hard training at altitude with a short restitution, due to short days in the winter. "Some participants hit the wall and I started to wonder why", says R¿nsen who now is in charge of the health of the Norwegian national alpine ski team for the winter Olympics in Salt Lake City.
