ABSTRACT
We search if between female groups of highly trained both walkers (W) and swimmers (S) holding different relative best sport performance (speed) could have different numeric values of Phasell V02 exponential mean response time (MRTexp) from a ramp cycle-ergo-spirometric (incremental) test (25 Watts·2min-1) until volitional fatigue. The direct measurement time course of V02 response (mL . min-1) to ergometric exercise was transformed in seconds. This time course was computer-modelled using linear least squares regression techniques on experimental V02 data from the ramp test. Vital signs were measured in our volunteers immediately after they were resting for 20m in in a seated position. Peak ergo-spirometric and physiological values were obtained at the moment of maximal effort at 2,240 m of altitude. Speed (m . s-1) was computed as distance of the competitive sport event (m) 1 total time u sed (s). In spite on speed differences observed (P ‹ 0.05) between W (3.08 ± 0.17) and S (1.36 ± 0.13) the general anthropometry, vital signs, maximal ergo-spirometry, and Phasell V02 relative to total body mass (mL. min-1 • kg-1TBM) kinetics resulted similar (P › 0.05) between groups (MRTexp, s: FWG - 14.2 ± 7.5, FSG - 24.5 ± 19.0) as wel l as did V02 peak (mL . min.-1. kg-1TBM: W = 46 ± 13, S - 44 ± 8). lt is concluded that VO2 would not solely be a determinant parameter and that other biophysical variables would also contribute to race walking and sport swimming success.
