Title FIZIOLOŠKO I BIOMEHANIČKO OPTEREĆENJE BICIKLISTIČKE UTRKE NA 1000 KILOMETARA Title (english) PHYSIOLOGICAL AND BIOMECHANICAL LOAD OF BICYCLING RACE ON 1000 KILOMETERS Author Eugen Popović Mentor Daniel Bok (mentor)Committee member Daniel Bok (predsjednik povjerenstva)Committee member Vlatko Vučetić (član povjerenstva)Committee member Davor Šentija (član povjerenstva)Granter University of Zagreb Defense date and country 2021-09-27, Croatia Scientific / art field, SOCIAL SCIENCES Abstract Cilj istraživanja je bio utvrditi opterećenje i natjecateljske zahtjeve tijekom biciklističke utrke na 1000 kilometara podijeljene na 4 etape. 3 rekreativna biciklista dobi: 37,93±9,9 godina; visine: 182,63±6,9 centimetara i tjelesne mase: 90,44±8,8 kilograma su dobrovoljno pristali na sudjelovanje u istraživanju. Glavni parametri za praćenje i analizu podataka su snaga, frekvencija srca i subjektivna procjena opterećenja (SPO). Inicijalnim testiranjem u dijagnostičkom centru Kineziološkog fakulteta u Zagrebu su utvrđene zone intenziteta. Dobivene su vrijednosti aerobnog praga, anaerobnog praga i maksimalnog primitka kisika u varijablama snaga i frekvencija srca. Glavni događaj: biciklistička utrka na 1000 kilometara, započela je 9 dana nakon inicijalnog testiranja. Praćene varijable za vrijeme natjecanja su: snaga, frekvencija srca i SPO. Ispitanici su vozili na osobnom biciklu opremljenim s mjeračem snage i ciklokompjutorom, a oko prsnog koša je nošena traka za mjerenje frekvencije srca. SPO je prikupljan svaka 3 sata pomoću tablice i kemijske olovke od strane ispitanika. Utvrđena je razlika u provedenom vremenu po zonama intenziteta u varijablama snaga i frekvencija srca tijekom etapa. SPO je ostala bez značajnih promjena tijekom etapa. Rezultati pokazuju najviše provedenog vremena u zoni 1 u varijabli snaga, zoni 2 u varijabli frekvencija srca, te u zoni 1 u varijabli SPO. Može se zaključiti kako biciklistička utrka na 1000 kilometara dovodi do progresivnog opadanja prosječne snage i frekvencije srca te neznatnog povećanja SPO-a. S obzirom na karakteristike natjecanja i dobivene rezultate, priprema za ultra dugotrajna natjecanja zahtijeva visok ekstenzitet treninga (30-40 sati tjedno) u kombinaciji s niskim intenzitetom. Potrebno je najviše vremena provoditi u zoni 1 (70%), zoni 2 (25%) i zoni 3 (5%).
Abstract (english) The aim of this study is determine load and competitive requirements during a 1000 kilometers bike race divided into 4 stages. 3 recreational cyclists age: 37,93±9,9 year; height: 182,63±6,9 and body mass: 90,44±8,8 kilograms have voluntarily agreed to participate in the research. The main parameters for data monitoring and analysis are: power, heart rate and rate of perceived exertion (RPE). Initial testing in diagnostic center at Faculty of Kinesiology in Zagreb intensity zones have been identified. Values were obtained at aerobic threshold, anaerobic threshold and maximal oxygen uptake in the variables power and heart rate. Main event: 1000 km bicycle race, began 9 days after initial testing. The variables monitored during the competition are: power, heart rate and RPE. Participants rode a personal bicycle equipped with power meter and a cyclocomputer, and around the chest it was worn heart rate measurement tape. RPE was collected every 3 hours using a spreadsheet and a ballpoint pen by participants. A difference in time spent was found in the variables power and heart rate during the stages. RPE remained without significant changes during the stages. The results show the most time spent in zone 1 in the variable of power, zone 2 in the variable of heart rate and in zone 1 in the RPE variable. It can be concluded how cycling race at 1000 kilometers leads to a progressive decline in average power, heart rate and a slight increase in RPE. Given the characteristics and the results obtained, preparation for ultra long competitions requires high training extent (30-40 hours per week) combined with low intensity. It takes the most time to spend in zone 1 (70%), zone 2 (25%) and zone 3 (5%).
