摘要:The purpose of this study was to compare the effectiveness of high-intensity interval training such as Billat 30s-30s training (HIIT) vs moderate intensity endurance training (CT+HIIT) on aerobic parameters in young adults men. The study involved 40 young adults men (20,15±0,56 years) who were randomly divided into the two training groups: Billat 30s working at 100% of vVO 2 max and 30s recovery of 50% of vVO 2 max (HIIT; N=20); and the moderate intensity endurance training (CT+HIIT; N=20). The training programs have lasted 4 weeks, three times per week. The measurement was carried out at two time points at Cosmed treadmill (model T 150) gas analysers (Quark b2) breath-by-breath method. Participants were tested for each of the following parameters: relative maximum oxygen consumption (rVO 2max ); absolute maximum oxygen consumption (aVO 2max ); minimum speed that athletes run when they reach VO 2max (vVO 2 ) and maximum heart rate (HR max ). To determine difference between effect of trainings, we used a Mixed factorial analysis of variance. Results indicated there was effect from time in rVO 2max , aVO 2max and vVO 2max (p<0,05) and effect from group in variable vVO 2max (p<0,05). There was a significant effect interaction group x time in rVO 2max and vVO 2max . In conclusion HIIT and CT+HIIT both elicit significant improvements in the aerobic parameters after 4 weeks. However, HIIT was more effective for improving rVO 2max and vVO 2max than CT+HIIT in healthy, young adults.
