Sažetak
The purpose of this study was to assess the reliability and the validity of a modified version of the Multi-stage Shuttle-Run Aerobic Test 20m. The proposed version is a hexagon with 10m side distances each named Hexagon Multi-Level Running Aerobic Test 10m. The same parameters (ending level, maximum speed and heart rate at the finish) were measured and the VO2max was estimated in both tests using the Multistage Shuttle-Run Aerobic Test 20m protocol and tables. For the proposed test the reliability evaluation was applied on a sample of 18 students (age 20.8±0.9yrs) twice with a 48h time interval, giving high correlations in maximum speed and VO2max (r=0.99) and ending level (r=0.98). For the Hexagon Multi-Level Running Aerobic Test 10m the validity assessment of the measured variables of this test were compared with the same variables of the Multistage Shuttle-Run Aerobic Test 20m in 62 trained adolescents (age 13.7±0.7yrs). The validity coefficients for all the variables between the two tests were r=0.86 (p<0.01). Furthermore, the participants’ performance profile was significantly higher in the proposed version, (p<0.05) while the mean VO2max of adolescents was significantly higher in this test than in the prototype Multistage Shuttle-Run Aerobic Test 20m (46±6.2 vs 40.8±4.9ml/kg • min), (p<0.05). Conclusively, it can be inferred that the Hexagon Multi-Level Running Aerobic Test 10m is not only a reliable and easy to use test but also, compared to the valid Multistage Shuttle-Run Aerobic Test 20m, it can be an objective test for the evaluation of aerobic performance in adolescents.
