Biomehanika in fiziologija kolesarjenja v klanec


clanek-revija-bicikel

 

V aktualni številki revije Bicikel.com (9-10 2016) je izšel obsežnejši članek na temo kolesarjenja v klanec. Temo sem skušal zajeti kar se da široko, a hkrati dovolj podrobno in bralcu razumljivo. Strokovnjaki naj zato ne zamerijo, če se mestoma pojavljajo prekomerne poenostavitve. Vendarle gre za poljudno revijo in ne znanstveno publikacijo. Vabim vas k ogledu članka v reviji, spodaj pa prilagam seznam gradiva, ki zaradi prostorske omejitve ni bil vključen v tiskano objavo.

Slika 1. Različne pozicije pri vožnji navkreber predstavljajo različne obremenitve telesa. Aerodinamičen položaj, za katerega je značilen majhen kot v kolku, je z vidika aerobne zmogljivosti manj učinkovit in manj udoben. Pri vzponih nad 7% naklona je optimalneje voziti v pokončni drži, saj tedaj zračni upor ne predstavlja bistvenih izgub. Vir: lasten
