Determination of the maximal oxygen uptake through the new basketball spesific field test

ABSTRACT DETERMINATION OF THE MAXIMAL OXYGEN UPTAKE THROUGH THE NEW BASKETBALL SPESIFIC FIELD TEST The aim of this study was to develop a new basketball court based test that measures indirectly the maximal oxygen uptake and to determine the reliability and validity of this test to measure aerobic power. A total of 1.5 miles (2414 m)-an aerobic endurance test including the side steps for the high defense and attack on the three-point line and running on the sideline was designed intended to be completed as soon as possible. Healthy, 15 years old, 11 male basketball players' (training background 5.18 years, mass 84.4 kg, height 190.3 cm) VO2max levels measured directly in the laboratory test (gold standard) showed a significant negative correlation with the duration of basketball-specific field test (r= -0.705, p= 0.015). The regression analysis with Basketball-Specific Field Test was demonstrated in moderate validity (R² = 0.390), then regression formula was developed to estimate VO2max level: VO2max = 122.617 – 5.461 x [basketball-specific field test duration (min)]. Reliability was evaluated by test-retest method, there was no difference between the periodically repeated duration of Basketball Specific Field Test (p > 0.05) and it showed high reliability (%CV: 8.81 and ICC: 0.90). "Basketball Specific Field Test" which was proved reliability and validity for the measure of aerobic power is thought to help to coaches and athletes by means of its properties which ensure the easy and practical application, not to require expensive equipment, specialist staff, not to have any health risk and by using basketball-specific movements in basketball courts.
