This work analyzed the changes that take place between normal freestyle normal swimming (NS) and resisted swimming in freestyle with parachute (RSWP) in the variables of average speed of I swim (S), stroke frequency (SF), stroke length (SL), distance of I swim (DS), time of the test (TT), heart rate (HR) and blood lactate concentration (LAC). They carried out two studies, the first one with 16 swimmers of national level understood among 19 and 24 years that made four tests that consisted on swimming to maximum intensity during 10 and 45 seconds, using NS and RSWP. The second study compared 18 swimmers of regional level, among the 16 and 23 years that they carried out two you prove pre-treatment and two post-treatment of 50 meters to maximum intensity, and using NS and another by means of RSWP. During eight weeks they carried out specific trainings of speed, where the group control made NS and the experimental group RSWP. In the first study a variance analysis was used for repeated measures and for the second the tests t. The results showed as RSWP, it produces significant variations with concerning NS, being observed a reduction of SF, SL, S and DS. In HR and LAC the use of RSWP, doesn't produce significant variations regarding NS, except in the LAC in the 10 seconds, where significantly bigger values are shown in RSWP. The tests of 10 seconds show a significant increase of SF and S and a decrease of SL and DS with regard to those of 45 seconds. In the tests of 45 seconds they take place a significant increase HR and LAC, with regard to that of 10 seconds. In the second study significant differences are not appreciated among the two groups after the 8 weeks of training. In the two groups a significant decrease was observed in TT, SF, LAC and a significant increase of S in all the tests, except in that of RSWP of the experimental group, the rest of the parameters didn't show significant differences between the measures pre and post-treatment.
