Reactive Agility Performance in Handball ; Development and Evaluation of a Sport-Specific Measurement Protocol

There is no current study that examined sport- specific tests of reactive-agility and change-of- direction-speed (CODS) to replicate real-sport environment in handball (team-handball). This investigation evaluated the reliability and validity of two novel tests designed to assess reactive-agility and CODS of handball players. Participants were female (25.14 +/- 3.71 years of age ; 1.77 +/- 0.09 m and 74.1 +/- 6.1 kg) and male handball players (26.9 +/- 4.1 years of age ; 1.90 +/- 0.09 m and 93.90 +/- 4.6 kg). Variables included body height, body mass, body mass index, broad jump, 5-m sprint, CODS and reactive-agility tests. Results showed satisfactory reliability for reactive-agility-test and CODS-test (ICC of 0.85- 0.93, and CV of 2.4-4.8%). The reactive-agility and CODS shared less than 20% of the common variance. The calculated index of perceptual and reactive capacity (P & RC ; ratio between reactive- agility- and CODS-performance) is found to be valid measure in defining true-game reactive- agility performance in handball in both genders. Therefore, the handball athletes' P&RC should be used in the evaluation of real-game reactive- agility performance. Future studies should explore other sport-specific reactive-agility tests and factors associated to such performance in sports involving agile maneuvers.
