BACKGROUND: Several methods of aerobic capacity evaluation have been applied to assess and prescribe the training sessions in swimming. However, most protocols either show exhaustive characteristics, triggering transitory stress period or several visits, influencing the session’s organization. Thus, the purpose was to validate a double-bout exercise protocol for non-exhaustive aerobic capacity determination of swimmers.
METHODS: Twelve swimmers were submitted to non-exhaustive and Maximal Lactate Steady State (MLSS) protocols. Non-exhaustive tests (NET) were performed into 4 sessions with randomized intensities 60–80 s/100m. Sessions were divided in two bouts with same intensity, duration (180 s) and interval (90 s). Linear interpolation of Δ Heart Rate (HR) and Δ Lactate (Lac) enabled determination of a "null" Δ. NET and MLSS were performed for determination of reproducibility and validity respectively.
RESULTS: The velocity (s/100m) measured by Δ HR (test=75.16±0.84; retest=74.81± 0.75) and Δ Lac (test=75.08± 0.87; retest=75.14± 0.81) did not differ from MLSS (74.00± 1.20). Significant correlation was found between test and retest for HR (p=0.001), Lac concentration (p=0.001) and MLSS (HR test p=0.0001; HR retest p=0.0001; Lac test p=0.002; Lac retest p=0.0001).
CONCLUSION: In conclusion, non- exhaustive test evaluated by Δ HR and Δ Lac was reproducible and valid to determine the aerobic capacity in swimming.
