PURPOSE
To evaluate the utility of an incremental swimming test for monitoring seasonal changes in performance of elite swimmers.
METHODS
Olympic representative 100- to 400-m swimmers (10 males, 9 females) performed a 7 × 200-m incremental swimming step test several times throughout each 6-month season during 1998–2002. Each season concluded with a national or international competition. Log transformation and repeated measures mixed linear modeling were used to derive estimates of percent change in the mean and within-swimmer coefficient of variation (CV) for swim times between seasons and for the following test measures between phases and seasons: speed, stroke rate, stroke count and heart rate at lactate threshold; speed for the maximal (last) 200-m step; and maximal lactate. Change in competition time was modeled as a linear function of change in each of the step-test measures between season. We also determined the 3-day retest typical error for the test measures in a reliability study of 12 of the swimmers.
RESULTS
Test measures directly related to swimming performance showed cyclical improvement (mean ~2%) from early through to taper phases within each season, and within-swimmer variation was of similar magnitude. These changes can be monitored confidently in individuals, because the typical error of the test measures was substantially smaller (e.g. lactate-threshold speed, 0.7%; maximal speed 0.6%). Competition times improved slightly each season (0.2%) against a within-swimmer variation of 1.0% between competitions, but typical (1 × CV) changes in test measures between seasons predicted worthwhile changes in competition time (> 0.4%) only for tests in the taper and only for speed (0.8%) and stroke rate (0.6%) at lactate threshold and for maximum lactate (0.5%).
CONCLUSION
The step test can track changes in a swimmer's performance during a season, but it appears to be useful for predicting competitive performance only during the taper.
