VALORACIÓN DE LAS ALETAS EN FUNCIÓN DEL TIEMPO EMPLEADO EN PRUEBAS DE NADO Y REMOLQUE DE MANIQUÍ

Abstract

The objective of the present paper was to evaluate the effect of different swim fins in trials of free swimming and manikin carry. The sample consisted of 13 subjects (all males, average age of 22.9 ± 0.8 years, average weight of 74.5 ± 8.7 kg, and average height of 175.7 ± 6.8 cm). The subjects swam under two situations, both a distance of 50m, one free swimming and the other swimming while carrying a manikin. These situations were done under each of the following conditions: without fins, with soft fins, with short fins, with hard fins, and with fibre fins. The order of the trials was random and the subjects had at least 30 minutes of recovery between trials. Results show no significant differences between using swim fins or not in the 50m free swim, though there are significant differences in the manikin carry. It was also observed that the hard swim fins contributed to faster times in free swimming and manikin carry. In every case, fatigue had an effect on the second part of the trial, and it was significant in the 50m manikin carry.
