Introduction: Swimming stability analysis can be conducted at all times of the athlete's career, allowing to elucidate continuous improvement or the moment a plateau is reached in the results of a race. Objective: To analyze the stability of the performance of freestyle swimmers during 4 years. Material and Methods: Quantitative study and historical survey. Data were obtained from the 50m, 100m and 200m free trials of the state federation's website. A total of 78 swimmers (50m = 52; 100m = 19; 200m = 7) participated in the sample from 2007 to 2010. The analysis was performed by means of mean stability, intraclass correlation coefficient (ICC), and normative stability, analyzed by the Pearson correlation coefficient (r), in addition to the analysis of the variation in performance, repeated measures ANOVA and the relative variation in performance (∆%) between seasons. Results: They showed an improvement in swimmers' performance over time (13,3% - 50m; 13,6% - 100m and 15,4% - 200m) and the stability during the 2007-2010 season expressed by the ICC was high: 0.90 (95% CI: 0.66-0.96) at 50m; 0.81 (95% CI: 0.34-0.94) at 100m; 0.83 (95% CI: 0.38-0.97) at 200m. Conclusion: Most athletes maintained improvement in results at all distances.
