Methods: Eighteen cyclists (between 15 and 20 years, n= 7 women, n= 11 men) were included in this study (age:17.50 years, height: 173.22 cm, body mass: 63.38 kg and body-mass index: 20.95 kg/m2). The cyclists were randomly divided into two groups. The training group (GHIIT, n= 9) participated in high intensity interval training two times per week for 6 weeks, while the Control Group (GCON, n= 9) completed moderate intensity continuous training (MICT). The training’ HR was conducted at 80%-95% HRmax for the first four weeks. In the last two weeks, the training’ HR was increased to %100 HRmax. The height, body mass, body fat %, aerobic and anaerobic power were measured. The maximal oxygen consumption (VO2max) was measured using a portable metabolic analyzer and, the traditional VO2max test followed a standard incremental design. Anaerobic capacity was evaluated by Wingate Anaerobic Test (WAnT) in 30sec. Results: There was no significant difference in body fat %, body mass, BMI, powerpeak, powermean, and powermin between GHIIT and GCON at the end of the training program (p>0.05). However, there was a significant difference in VO2max (p= 0.001) between GHIIT and GCON at the end of training (p<0.05). Conclusion: The high intensity interval training occurred a significant increase in VO2max. Anaerobic power improved but this result was not significant. Nevertheless, HIIT may use to improve in VO2max in young trained cyclists in short period. © JPES.en10.7752/jpes.2022.01027info:eu-repo/semantics/openAccessAerobic PowerAnaerobic powerCyclistHIITVO2 maxArticle2212102152-s2.0-85126610157Q3
