Primary Outcome Measures

Name	Time	Method
Improvement of Cardiorespiratory Fitness verified by Ergospirometry.

Secondary Outcome Measures

Name	Time	Method
Improved Running Economy verified through oxygen consumption and speed (80% of respiratory compensation point). Oxygen consumption will be considered as the average of the final 30 seconds of the ten minute effort verified by ergospirometry.;Change in ventilatory threshold verified by the first increase in ventilation vs. incremental test speed and / or nonlinear increase in oxygen equivalent (Ve • VO2-1) vs. incremental test speed (BINDER et al., 2008). The respiratory compensation point will be determined by the second increase in ventilation (Ve) vs. incremental test speed and / or nonlinear increase in carbon dioxide equivalent (Ve • VCO2-1) vs. incremental test speed (BINDER et al., 2008).;Improvement in performance time of 5km by hand timer performed by experienced appraiser.
