A Comparison of Graded Exercise Test and Two Different Field Tests to Evaluate the Cardiopulmonary Function in Elite Handball Athletes

The purpose of this study is to establish a simpler way to assess cardiopulmonary function in handball athletes whose continuous aerobic ability is vital in games using field tests, as well as to provide basic data on changes in lactic acid concentration. A total of 8 youth elite male handball athletes participated in this study. Participants visited three times in total. The first was assigned to graded exercise test and body composition measurements. Participants were then randomly assigned to a 20-meter shuttle ride or Yo-Yo Intermediate Recovery. All participants measured the lactic acid concentration after each exercise test. There were no significant differences in the VO2max (ml/kg/min) results in each test. There was no significant difference immediately after exercise of each test, after 5 minutes, after 10 minutes, and after 20 minutes. Compared to the golden standard GXT, there is no difference in maximum oxygen intake and lactic acid concentration after the two field tests, so both tests are expected to be efficiently used to evaluate the aerobic ability and develop training programs in the field.
