A COMPARISON OF REPEATED WINGATE BASED OF HIGH INTENSITY INTERVAL TRAINING AND MODERATE INTENSITY CONTINUOUS TRAINING ON AEROBIC CAPACITY UNDER NORMOBARIC HYPOXIA

Abstract

Aerobic capacity is very important for all people in terms of health and performance. Therefore, important organizations such as the World Health Organization (WHO) and the American College of Sports Medicine (ACSM) generally recommend that adults should perform physical activity maintain and improve their aerobic capacity. This study aimed to compare the effects of 8-week Repeated Wingate (RW) based of high-intensity interval training (HIIT) vs. moderate-intensity continuous training (MICT) on the aerobic fitness in recreationally active young adults under hypoxic and normoxic conditions. Thirty-two recreationally active young adults (age:22,37±2,30 years) were randomly assigned to Hypoxia RW(n=8), Normoxia RW(n=8), Hypoxia MICT (n=8), Normoxia MICT (n=8) group training protocol. The HIIT groups consisted of 4-7×30-s Wingate “all-out” sprints with 4 min of passive rest. The MICT groups completed 25-40 minutes of continuous running. Before, 4-week and after the 8-week interventions the following tests were completed: maximum oxygen consumption (V̇O2max), anaerobic threshold oxygen consumption (AT VO2), time to exhaustion (TTE) be determined from the Bruce treadmill protocol and submaximal oxygen consumption (Submaximal VO2) be determined from the modified Astrand protocol. Statistical difference was found between the 4th and 8th weeks in the HIIT and MICT groups according to the pre-tests (p ≤ 0.05). However, no difference was found between the condition (Hypoxia - Normoxia) and training methods (HIIT-MICT) (p ≤ 0.05).
