Relationship between CHU-Test Results and High-intensity Running during Soccer Matches [Received August 26, 2021; Accepted March 1, 2022] The purpose of this study was to investigate relationship between the results of CHU-Test (a Test to Carry out High-intensity running with Utmost turns, repeatedly) and high-intensity running (HIR) during soccer matches. Twenty-four male soccer players (university students) aged 19.3±0.9 years were participated in the study. To assess intermittent endurance in soccer, participants performed the CHU-Test and soccer matches. They put on global positioning system (GPS) devise in soccer matches to measure total distance covered (TD), distance covered more than 18.0 km/h (HIR), ratio of HIR to TD (HIR/TD) and distance covered more than 24.0 km/h (Sprinting). CHU-Test results of participants were 17.9±2.6 times in first time and 18.0±3.1 times in second time. Between their results, there was a significant reliability coefficient of 0.95 (p < 0.05). Additionally, significant correlation coefficients (r = 0.67 to 0.76) were showed between the CHU-Test results and HIR, HIR/TD and Sprinting at full time (90-minute), peak 5-minute period and final 15-minute period (75 to 90 minute) of soccer matches (p < 0.05). From these results, it was suggested that the CHU-Test was a field test that was relevant to HIR during soccer matches. Keywords: GPS, intermittent endurance, running performance, physical fitness |
