A few days ago I talked about the challenge of Nike for get two hours in the marathon, lowering the current record of 02:02:57 in almost three minutes Kimetto: something that would undoubtedly be one of the greatest sporting achievements of our time. For this purpose have already chosen the place (car circuit of Monza in Milan) and their weapons: sneakers with a new technology that promise a higher return on energy.
The slippers have a sheet of carbon fibre that minimizes the loss of power of the corridor in each stride, doing so efficiently and delaying the onset of muscle fatigue. However, some voices have risen as wondering If these new shoes could cross the border of what is considered technological doping.
Shoes aerodynamic shape and the carbon fiber contained in the midsole plate, together with adjusted weight (less than 200 grams) are the big bets of Nike to get the challenge of lowering of two hours in the marathon. Also the clothing designed exclusively for the event (t-shirts with micro-perforations, meshes, sleeves and Socks) are specifically designed to facilitate the achievement of the record.
Is not the first time that Nike gets into a laboratory for designing equipment that improves the options of athletes: We could see the Nike Swift technology, which could be lowered two hundredths of a second for each 100 meters race at the Beijing 2008 Olympic Games.
Nike is not the only brand, nor much less, that develops this type of technology in footwear that allows you to save energy and run faster: the boost of Adidas sneakers or the Saucony Everun also refer to different combinations of foam in the midsole you improve the efficiency of the corridor.
Where it begins and where it ends the technological doping?
The difficulty here is the hour of decide what is and what is not technological doping. A shoe designed to improve the activity of a corridor can be considered doping? You can really improve the performance of the athlete or just not impede it?
Perhaps the much-talked-about case in recent years was the LZR swimsuits from Speedo, used by Michel Phelps and produced in collaboration with NASA. In 2010 he ended the controversy over whether bathing suits could be considered technological doping, removing them from the competition, Since it was considered that they increased both the speed and the buoyancy of the swimmers.
In the case of the world record of marathon that Nike wants to beat, it will have to be it International Federation of athletics (IAAF) which need to pronounce on the matter, saying if effectively adopts the materials used during the test.
What do you think? Could these new shoes are considered technological doping for athletes?
