Abstract

The use of a protocol capable to evaluate both aerobic and anaerobic parameters of capacity and power in one single test session could be interesting in order to enhance practical applicability of metabolic energy production evaluation. Before using such protocol parameters, it is mandatory to study their validity. This thesis aims to check applicability, reliability and validity of a tethered running 3-minute all-out test (AO3¿) to evaluate aerobic and anaerobic capacity and power parameters in laboratory and field track. Experimental designs were adopted to verify test-retest reliability, comparison between the 3-minute test and other well stablished protocols, and tests of metabolic consistency based on physiologic data. Overall, experimental design was divided in five experiments. First, the existence of an individual resistance to manifest maximal mechanical power in all-out efforts was investigated, as well as its test-retest reliability. Results proved not only this resistance magnitude around 16% body mass, as a high test-retest reliability. The second experiment intend to verify test-retest reliability of anaerobic capacity (ATA), anaerobic power (Pmax) and aerobic capacity (Pfinal) obtained by the 3-minute all-out, as well as Pmax validity. Results proved these parameters to be reliable, and no statistical difference between Pmax measured in a 3-minute and a 30-second test. Third experiment investigated aerobic capacity, anaerobic capacity and aerobic power validity (VO2pico). Results showed aerobic power validity, an overestimation of aerobic capacity and a tendency to correlation between several anaerobic capacity parameters and ATA. Fourth and fifth experiments were performed in the track field, and verified the 3-minute all-out test parameters reliability, compared it to a 30-second test results and verified the applicability of the optimum resistance to generate mechanical power to efforts longer than 6-seconds. Results showed ideal resistance to produce mechanical power in field running to be around 20.5% body mass, with good reliability. Further, the 3-minute test parameters had good test-retest reliability as in laboratory, and concordance between 3-minute and 30-second power development. However, the ideal resistance to develop mechanical power in 6-second efforts may not be the same to 30-second efforts. The 3-minute all-out test seems to exert valid parameters of aerobic and anaerobic power, but underestimate anaerobic capacity and overestimate aerobic capacity (AU)
