Testmetodens betydelse för VO2peak och testtid: en jämförelse mellan två kombinationstest

Tests aimed to verify VO2max should consist of incremental loading during 8 to 12 minutes with 3 to 6 minutes at each load. Time at each load during incremental lactate threshold tests should be 3 to 8 minutes. A combination between a VO2max test and a lactate threshold test is time-saving for both athletes and test laboratory. This study compared two types of combined tests with the hypothesis that lower and more frequent increment loading, near/after OBLA 4 mM, results in shorter test duration and that the subjects´ results for VO2peak will be higher. Method: 10 women (age 27.7 ± 6.2) performed two combination tests (A and B). The workload during A was initially 40 W whereupon the workload subsequently increased by 40 W every third minute until exhaustion. B was initially designed as A until the subject was close to OBLA 4 mM, where the subject completed the ongoing interval on which the load increased every 30 seconds with 20 W until exhaustion. No significant difference between A and B for the value of VO2peak (l/min) (p = 0.664), VO2peak (ml/kg/min) (p = 0.578) or for the total testing time (p = 0.300). The results from test A and B performed on trained women reject the tested hypothesis. However, the number of subjects and the fact that the test has not yet been performed in specific sports should be taken into consideration before the hypothesis is completely rejected. The major problem of test B is to decide when to make the change in the test procedure (faster and smaller increments).
