Evaluation of Force Production and Fatigue using an Anaerobic Test Performed by Differently Matured Swimmers.

The purpose of this research was to characterize fatigue determining thresholds in force-to-time curves produced during 30 second tethered swimming efforts. Ninety swimmers of three maturational groups took part in the study. Values of maximal, mean, and minimum force were determined, as well as the variation coefficient of the mean force. The anaerobic fatigue thresholds were determined on the individual force-totime curves, and typical stroke cycles were determined before and after the fatigue occurrence. Typical force cycles were quantitatively analysed. It was possible to conclude that force tends to increase with maturation in males. In females, tethered force seems to stabilize after puberty.
