• Resumen

  • This study compared 2-interval swimming training programs of different work interval durations, matched for total distance and exercise intensity, on swimming performance, aerobic adaptations, and technical parameters. Twenty-four former swimmers were equally divided to short-interval training group (INT50, 12�16 × 50 m with 15 seconds rest), long-interval training group (INT100, 6�8 × 100 m with 30 seconds rest), and a control group (CON). The 2 experimental groups followed the specified swimming training program for 8 weeks. Before and after training, swimming performance, technical parameters, and indices of aerobic adaptations were assessed. [IOTA][NU][TAU]50 and [IOTA][NU][TAU]100 improved swimming performance in 100 and 400-m tests and the maximal aerobic speed (p <= 0.05); the performance in the 50-m swim did not change. Posttraining V[Combining Dot Above]O2max values were higher compared with pretraining values in both training groups (p <= 0.05), whereas peak aerobic power output increased only in INT100 (p <= 0.05). The 1-minute heart rate and blood lactate recovery values decreased after training in both groups (p < 0.01). Stroke length increased in 100 and 400-m swimming tests after training in both groups (p <= 0.05); no changes were observed in stroke rate after training. Comparisons between groups on posttraining mean values, after adjusting for pretraining values, revealed no significant differences between [IOTA][NU][TAU]50 and [IOTA][NU][TAU]100 for all variables; however, all measures were improved vs. the respective values in the CON (p < 0.001�0.05). In conclusion, when matched for distance and exercise intensity, the short-interval (50 m) and long-interval (100 m) protocols confer analogous improvements in swimming performance, in stroke cycle parameters, and in indices of aerobic adaptations after 8 weeks of training.
