Sažetak

Kardio-respiratorna izdržljivost predstavlja jednu od najvažnijih determinanti uspešnosti u sportskim aktivnostima. Kako bi se sportista što bolje pripremio za sportske izazove mora da bude izložen odgovarajućem treningu koji treba da bude baziran na individualnim fiziološkim pokazateljima opterećenja tokom aktivnosti. Iako se trenažno opterećenje može odrediti na više načina, intenzitet treninga se najčešće određuje preko laktatnog praga uzimanjem uzoraka krvi, ili preko ventilatornog praga praćenjem razmene gasova. Takvi podaci, ipak, predstavljaju zakasnele indirektne pokazatelje povećane anaerobne resinteze ATP-a. Mišićna oksimetrija, zasnovana na blisko-infracrvenoj spektroskopiji (NIRS), predstavlja neinvazivnu metodu koja obezbeđuje informacije o promenama stanja kiseonika u hemoglobinu i potencijalno predstavlja pogodnu tehniku prepoznavanja nivoa opterećenja direktno u radnoj muskulaturi.
