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

Abstract

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.

Effects of Black Maca supplement on isokinetics muscular performance of elite women’s handball players: placebo-controlled, crossover study

“…This study shows that the 20 m-shuttle run was significantly higher in the BM group than the baseline and placebo group. The 20 m-shuttle run is typically used to measure cardiopulmonary endurance, which can be replaced by VO2max as a field test (23). Maca administration also increased the relative proportion of contraction and relaxation before ischemia/recurrent, suggesting that the heart was better prepared for ischemia challenges with higher energy storage and muscle economy (24).…”
