- Abstract
Purpose: To assess the concurrent and predictive validity of the 3-minute all-out test (3MT) against conventional methods (CM) of determining critical speed (CS) and curvature constant (D′) and to examine the test–retest reliability of the 3MT in highly trained swimmers. Methods: Thirteen highly trained swimmers (age 16 [2] y, weight 64.7 [8.5] kg, height 1.76 [0.07] m) completed 4 time trials and two 3MTs over 2 wk. The distance–time (DT) and speed–1/time (1/T) models were used to determine CS and D′ from 4 time trials. CS3MT and D 3 MT ′ were determined as the mean speed in the final 30 s of 3MT and as the speed–time integral above CS, respectively. Results: CS3MT (1.33 [0.06] m·s−1) did not differ from CSCM (1.33 [0.06] m·s−1, P >.05) and correlated nearly perfectly with CSCM (r =.95, P <.0001). D 3 MT ′ (19.50 [3.52] m) was lower than D DT ′ (23.30 [6.24] m, P <.05) and D 1 / T ′ (22.15 [5.75] m, P =.09). Correlations between D 3 MT ′ and D CM ′ were very large (r =.79, P =.002). CS and D′ between the two 3MT trials were not different (CS mean change = −0.009 m·s−1, P =.102; D′ mean change = 0.82 m, P =.221). Correlations between the two 3MT trials were nearly perfect and very large for CS (r =.97) and D′ (r =.87, P <.05), respectively, with coefficients of variation of 0.9% for CS and 9.1% for D′. Conclusion: The 3MT is a valid protocol for estimation of CS and produces high test–retest reliability for CS and D′ in highly trained swimmers.
