Title Usporedba različitih metoda programiranja VIIT-a kratkog formata Title (english) Comparison of different methods to prescribe HIIT Author Tin Juričić Mentor Jere Gulin (mentor)Committee member Jere Gulin (predsjednik povjerenstva)Committee member Vlatko Vučetić (član povjerenstva)Committee member Daniel Bok (član povjerenstva)Granter University of Zagreb Defense date and country 2024-09-27, Croatia Scientific / art field, SOCIAL SCIENCES Abstract Intenzitet aktivnosti najvažnija je akutna varijabla koju treba odrediti za izazivanje željene fiziološke adaptacije tijekom treninga izdržljivosti. Intenzitet VIIT-a najčešće se određuje kroz postotak MAB-a. Međutim nogometaši tijekom utakmice provode značajan dio vremena na intenzitetima iznad vVO2max, odnosno MAB-a. VIIT kratkog formata se također provodi intenzitetom koji prelazi MAB, stoga metoda koja koristi postotak MAB-a možda i nije najbolji izbor za programiranje individualiziranog VIIT-a. Metode programiranja koje koriste postotke vIFT-a i kombinaciju postotka ASR-a uzimaju u obzir i intenzitete iznad MAB-a, te kao takve imaju veći potencijal za programiranje individualiziranog VIIT-a kratkog formata. Cilj ovog istraživanja je utvrditi postoji li razlika u akutnoj reakciji nogometaša između vremenski definiranog VIIT-a programiranog koristeći postotak vIFT-a i treninga koji koristi postotak ASR-a. Pored toga, utvrditi koja će metoda programiranja VIIT-a biti superiornija u akumulaciji veće količine vremena u zoni ≥90% FSmax, uz što manji metabolički i percepcijski stres. Petnaest visoko treniranih nogometaša (dobi 20,33 ± 2,23 godina, visine 184,43 ± 5,88 cm i težine 76,63 ± 5,07 kg) odradili su dva VIIT-a u trajanju od 10 minuta koji su uključivali interval rada u trajanju od 15 sekundi na intenzitetima od 95% vIFT-a i 20%ASR-a (MAB + 20% ASR), te interval pasivnog odmora istog trajanja. Oba treninga rezultirala su visokim postotkom akumulacije vremena u zoni ≥90% FSmax. Međutim bez statistički značajne razlike između metoda programiranja VIIT-a u kardiorespiratornim p = 0,46 (t@90%FSmax), metaboličkim p = 0,58 (La) i percepcijskim p = 0,07 (SPOt) parametrima akutne reakcije.
Abstract (english) Exercise intensity is the most important acute variable that needs to be determined for inducing the desired physiological adaptation during endurance training. HIIT intensity is most commonly prescribed using percentage of MAS. However, soccer players spend a significant portion of their time during a match at intensities above vVO2max, or MAS. Short format HIIT is also performed at an intensity that exceeds MAS, so a method based on a percentage of MAS might not be the best choice for designing individualized HIIT. Methods that use percentages of vIFT and a combination of ASR percentage take into account intensities above MAS and, as such, have greater potential for designing individualized short format HIIT. The aim of this research is to determine if there is a difference in the acute response of soccer players between time - defined HIIT designed using a percentage of vIFT and training that uses a percentage of ASR. In addition, the study aims to determine which method will be superior in accumulating a greater amount of time in the ≥90% HRmax zone with minimal metabolic and perceptual stress. Fifteen highly trained soccer players (age 20.33 ± 2.23 years, height 184.43 ± 5.88 cm, and weight 76.63 ± 5.07 kg) completed two 10-minute HIIT sessions, each consisting of 15-second work intervals at intensities of 95% vIFT and 20% ASR (MAS + 20% ASR), followed by 15-second passive recovery. Both methods resulted in a high percentage of time accumulated in the ≥90% HRmax zone. However, there was no statistically significant difference between the methods in terms of cardiorespiratory p = 0.46 (t@90%HRmax), metabolic p = 0.58 (La), and perceptual p = 0.07 (RPE) acute response.
