| Abstract | Cilj istraživanja: Utvrditi utjecaj hlađenja središnje tjelesne temperature korištenjem rukavica za hlađenje na mišićnu izdržljivost u profesionalnih džudaša.
Ispitanici i postupci: U istraživanje je ukupno uključeno 7 profesionalnih džudaša. Istraživanje je provedeno kao randomizirano, križno ispitivanje koje se sastojalo od dva treninga na zračnom biciklu. Svaki trening sastojao se od četiri serije s trominutnim periodom odmora. U periodima odmora u jednom od treninga ispitanici su koristili CoolMitt® rukavicu za hlađenje, a u drugom za vrijeme odmora nije korištena nikakva tehnologija. Glavni ishod istraživanja bio je ukupni volumen treninga.
Rezultati: Prosječna dob sedam profesionalnih džudaša (2 žene i 5 muškaraca) bila je 23,0 ± 4,7 godina, a prosječno vrijeme treniranja džuda bilo je 16,6 ± 3,9 godina. Profesionalni džudaši ostvarili su ukupno veći volumen treninga ako su u pauzama koristili rukavice za hlađenje, nego ako iste nisu koristili (37,2 (28,6 – 50,4) kJ vs. 35,1 (27,0 – 41,6) kJ, p = 0,016). Profesionalni džudaši u prosjeku nisu dulje vremena održali intenzitet vježbe na barem 85% RM1 u niti jednoj od serija ako su u pauzama koristili rukavice za hlađenje, nego ako iste nisu koristili (p = 0,652). Nadalje ispitanici su percipirali svaku seriju tjelovježbe kao podjednako umarajuću neovisno o tome jesu li trening radili s ili bez rukavice za hlađenje (p = 0,422). U džudaša koji imaju bolje sportske uspjehe nije uočena razlika u volumenu treninga uslijed korištenja rukavice u odnosu na džudaše s lošijim sportskim uspjesima (34,0 (25,1 – 48,7) kJ vs. 36,9 (35,1 – 40,1) kJ, p = 0,949).
Zaključak: Korištenje rukavica za hlađenje povećalo je ukupni volumen treninga na zračnom biciklu u profesionalnih džudaša, a percipirani umor nije pokazao ovisnost o primjeni rukavice za hlađenje. |
| Abstract (english) | Objectives: To determine the effect of cooling on the core body temperature using cooling gloves on muscular endurance in professional judo athletes.
Subjects and methods: A total of 7 professional judo athletes were included in the research. The research was conducted as a randomized, crossover trial consisting of two training sessions on an air bike. Each workout consisted of four sets with a three-minute rest period. During the rest periods in one of the training sessions, the test subjects used a CoolMitt® glove for cooling, and in the other during the rest period, no technology was used. The main outcome of the study was the total training volume.
Results: The average age of seven professional judo athletes (2 women and 5 men) was 23.0 ± 4.7 years, and the average time of judo training was 16.6 ± 3.9 years. Professional judo athletes achieved a higher overall training volume if they used cooling gloves during breaks than if they did not (37.2 (28.6 – 50.4) kJ vs. 35.1 (27.0 – 41.6) kJ, p = 0.016). Professional judo athletes did not maintain the exercise intensity at least 85% of RM1 for a longer time in any of the sets if they used cooling gloves during the breaks than if they did not use them (p = 0.652). Furthermore, the subjects perceived each exercise series as equally tiring, regardless of whether they did the training with or without a cooling glove (p = 0.422). In judo athletes who have better sports success, no difference in training volume due to the use of gloves was observed in comparison to judo athletes with worse sports success (34.0 (25.1 - 48.7) kJ vs. 36.9 (35.1 - 40, 1) kJ, p = 0.949).
Conclusions: The use of cooling gloves increased the total training volume on the air bike in professional judo athletes, and perceived fatigue did not show dependence on glove use. |
