Za praćenje fiziološkog odgovora, sa ciljem utvrđivanja udjela energetskih procesa tijekom aktivnosti, najčešće se koriste frekvencija srca, primitak kisika, koncentracija laktata u krvi i subjektivna procjena opterećenja. Cilj ovog rada je usporediti akutne učinke specifične kombinacije intervalnog trčanja na dvije različite trake za trčanje. Takav tip treninga programira se po postotcima od maksimalne brzine sprinta ispitanika (MSS- maximal sprint speed). Jedna minuta intervalnog trčanja sastoji se od: 20 sekundi hodanja na 6km/h, 20 sekundi trčanja na 40% od MSS, 15 sekundi trčanja na 60% od MSS, 5 sekundi trčanja na 85% od MSS (motorizirani pokretni sag) ili maksimalni sprint (nemotorizirani pokretni sag). Trening se sastojao od 6x1 minute rada u kojem je interval odmora na početku svake minute novog intervala (aktivni odmor) a sastoji se od 20 sekundi hodanja na 6km/h. Jednu minutu i tri minute nakon treninga mjerila se koncentracija laktata u krvi, a ispitanici su nakon svake minute treninga izražavali svoju subjektivnu procjenu opterećenja. Frekvencija srca mjerila se tijekom cijelog treninga. Ispitanici u ovom istraživanju bili su studenti Kineziološkog fakulteta Sveučilišta u Zagrebu (n=15, dobi od 22,87±1.68 godina, visine tijela 179,44±6,32cm i mase tijela 74,95±6,38kg). U akutnim efektima između dvije različite trake istog protokola nema statistički značajne razlike u aritmetičkim sredinama akutnih varijabli dobivenih metodom Studentovog t-testa za zavisne uzorke. Koncentracija laktata u krvi na motorizanom pokretnom sagu nakon minute odmora je 13,30±2,28 mmol/L i nakon tri minute odmora je12,87±2,25 mmol/L. Koncentracija laktata u krvi na nemotoriziranom pokretnom sagu nakon minute odmora je 12,85±1,73 mmol/L i nakon tri minute odmora je 13,52±1,92 mmol/L. Maksimalna frekvencija srca tijekom treninga iznosi 197±5,26 otk/min na motoriziranom pokretnom sagu i 190, 38±5,12 otk/min na nemotoriziranom pokretnom sagu. Subjektivna procjena opterećenja nakon treninga na motoriziranom pokretnom sagu iznosila je 9,09±0,94, a na nemotoriziranom pokretnom sagu 9,75±0,45.
Abstract (english) Acute reaction represents the immediate response of the athlete's organic systems to a training program, and it is important to control it by monitoring various physiological indicators of the work of different organic systems. To monitor the physiological response, with the aim of determining the share of energy processes during activity, heart rate, oxygen uptake, blood lactate concentration and rating of perceived exertion are most often used. The aim of this work is to find out and compare the acute reaction of a specific combination of interval running on two different treadmills. This type of training depends on the maximal sprinting speed (MSS; maximal sprinting speed), by which this training is programmed. One minute of running interval is consisted of: a) 20 seconds of walking at speed 6 km/h, b) 20 seconds of running at speed 40% of MSS, c) 15 seconds of running at speed 60% of MSS, d) 5 second of running at speed 85% of MSS (motorized treadmill) or maximal sprint (non-motorized treadmill). The training is consisted of 6 minutes of running. The participants for this study were students of Faculty of Kinesiology University of Zagreb (n=15, age 22,87±1,68, body height 179,44±6,32 centimetres and body weight 74,95±6,38 kilograms). In the acute reaction between two different treadmills of same protocol there is no statistically significant difference in the statistical method of Student t-test. Lactates are measured before and at the end of the training 1 and 3 minutes after (LA: 13.09±2.28 mmol/L on the motorized treadmill and 13.24±1.83 mmol/L on non-motorized treadmill). Heart rate was measured during the entire training and at rest for 3 minutes while lactates were measured (197±5.26 bpm/min on motorized treadmill and 190.38±5.12 bpm/min on non-motorized treadmill). The rating of perceived exertion ranged up from very hard to maximal (9.09±0.94). Oxygen uptake was not measured in this study due to financial reasons.
