Variable identified in intermittent gradual tests
Abstract
This research has the aim of determining the objectiveness of PDFCv, obtain evidences of validation of the test proposed by Carminatti et al. (2004) and verify if the maximum and sub maximum variations identified in both tests are dependent-protocols. The tests used were the Shuttle run of 20m TLe (1984) and a test proposed by Carminatti et al.- TCar(2004). Twenty-six regional level male athletes (futsal and volleyball), (21.7 ± 3.0 years, 76.7 ± 14.6 kg, 179.3 ± 7.2 cm, 14.2 ± 5.9 % of body fat), were subdued to the test 1: TCar and Test 2: TLe. The rhythm in both tests was determined according to resonant signals. The determined variations were: corrected velocity peak (PS) and HR (Polar®-model S610i™) in each speed and deflection point of heart frequency by mathematical and visual methods. The determination of the HRPDv was carried out by 3 experienced evaluators, assuming the moda and in the lack of that, the average of the values of HRPDv from the 3 evaluators. Significant values of CCI were found to DPS-VDM and HRPDv on the TCar tests (0.91 e 0.90) and TLe (0.90 e 0.95), respectively, and that shows its objectiveness. The results suggested that the HRPD identified by visual or mathematical is not a dependent protocol, which does not occur for the speed variations (maximum or sub maximum). Evidences of application validity were found on the proposed test.
