Abstract

Subjektivna procjena opterećenja (SPO) je subjektivna mjera često korištena za propisivanje intenziteta kontinuiranih treninga. Metoda SPO također se pokazala valjanom za propisivanje intenziteta visoko-intenzivnih intervalnih treninga (VIIT) kod različitih populacija. Ciljevi ovog istraživanja bili su istražiti konstrukciju valjanost SPO za određivanje intenziteta VIIT-a koristeći kriterij „zlatnog standarda“; odrediti optimalnu kategoriju SPO za propisivanje VIIT-a i istražiti obrazac prilagodbe intenziteta, tj. brzine trčanja, tijekom sesija VIIT-a propisanih putem SPO.
U istraživanju je sudjelovalo 17 studenata Kineziološkog fakulteta Sveučilišta u Zagrebu prosječne dobi 24,2±5 godina. Ispitanici su proveli maksimalni progresivni test opterećenja i tri sesijeVIIT-a. Sesije su se sastojale od provođenja 3 × 3 minute trčanja intenzitetom definiranim na subjektivnoj procjeni opterećenja 6, 7 i 8 prema Borgovoj kategorijsko-omjernoj skali raspona 0-10, ispresijecanih s 2 minute pasivnog oporavka. Tijekom trenažnih sesija mjerene su vrijednosti srčanodišnih parametara i brzine trčanja, a po završetku treninga izmjerena je koncentracija laktata u krvi. Univarijatna analiza varijance za ponovljena mjerenja i Tukey post hoc analiza korištene su za testiranje razlika između VIIT sesija i pojedinačnih razlika između izmjerenih parametara.
Rezultati su pokazali da se VIIT pri SPO 6 značajno razlikuje u vremenu provedenom ≥90%VO2max, vršnoj i prosječnoj brzini, vršnom i prosječnom primitku kisika, vršnoj i prosječnoj minutnoj ventilaciji te koncentraciji laktata u krvi od VIIT-a pri SPO 7 i SPO 8. Osim u prosječnoj minutnoj ventilaciji nije bilo statistički značajne razlike između treninga pri SPO 7 i SPO 8. Iako je srčanodišni odgovor bio maksimiziran pri SPO 7, zbog velikih metaboličkih i lokomotornih zahtjeva, sugerira se da VIIT pri SPO 6 pruža optimalan sveukupni fiziološki odgovor.

Abstract (english)

Rating of perceived exertion (RPE) is a subjective measure of intensity often used for prescription of continuous endurance exercise. The RPE method also appears valid for prescription of high-intensity interval training (HIIT) in various populations. The aims of the study were to investigate the prescriptive validity of the RPE for HIIT sessions using “gold standard” criterion; to determine the optimal RPE category for HIIT prescription and to investigate the pattern of intensity, i.e. running velocity, adjustments during RPE-prescribed HIIT sessions.
Seventeen students from the Faculty of Kinesiology, University of Zagreb, at the age of 24,2 ± 5 participated in this research. They performed incremental exercise test and three sessions of HIIT. The sessions consisted of 3 x 3 minute running defined at RPE intensities of 6, 7 and 8 from Borg category-ratio-10 scale interspersed with 2 minute passive rest. During sessions cardiorespiratory parameters and running speeds were monitored and after training blood lactate concentration was measured. Analysis of variance for repeated measures and Tukey post hoc test were used for testing defferences between HIIT sessions and between individual differences among measured parameteres.
Results showed that HIIT performed at RPE 6 is significantly different at the time spent at ≥90%VO2max, peak and mean speed, peak and mean heart rate, peak and mean oxygen uptake, peak and mean minute ventilation and blood lactate concentration in comparison to HIIT performed at RPE 7 and RPE 8. Althought cardiorespiratory response is maximized during HIIT at RPE 7, because of high metabolic and locomotor stress, it is suggested that HIIT at RPE 6 provides optimal overall physiologial response.
