Abstract
The aim of this study is to investigate the potential benefits of 2 and 4 weeks of virtual reality (VR) exercise program with and without intermittent Nordic walking (INW) on VO2max and body composition markers including: body mass index (BMI), waist-to-hip ratio (WHR). , waist to height ratio (WHtR), body adiposity index (BAI), abdominal volume index (AVI), cone index (CI) and body shape index (ABSI) in adolescent girls. A randomized controlled trial on 80 adolescent girls (age 14 years old and 159 cm tall and 64.50 kg weight and 33.7656 ml/kg/min VO2max were randomly divided into VR, INW, VR+INW and control groups They did the VR intervention session with and without INW training for 2 or 4 weeks.Measurements were done at the beginning and in the follow-up phase (2 and 4 weeks after the intervention). parameters. Two weeks of INW or VR interventions had no significant effect on the cardiorespiratory fitness index and body composition. After INW training, a significant increase in VO2max values was observed compared to the control group (CI parameters = 0.046). and ABSI showed a significant improvement especially in the VR+INW group after 4 weeks of intervention (p value equal to 0.001 and 0.003, respectively). The 4-week intervention of VR with INW is associated with health status and can A non-pharmacological strategy to prevent physical inactivity and maintain health status in adolescent girls.
