• Resumen

  • Introduction:the muscular response on the main muscles of the propulsive phase of the upperlimb in the crawl swimming style has been evaluated by means of tensiomyography (TMG), whichwas carried out through three parameters: activation time (Td), contraction time (Tc) and maxi-mum deformation (Dm).The aim of this study is to evaluate the hypothesis of changes produced between lactic resis-tance training with passive rest and lactic resistance training with active rest.Material and methods:experimental study with ninety swimmers in the crawl stroke, with amean age of 20 years. The session with passive recovery and the session with active recovery pre-sented results with significant changes after the development of each of them in the Tc in thethree muscles analysed, being in the Pectoralis Major (PM),p= 0.001, in the Latissimus Dorsi(LD),p= 0.01 and in the Tríceps Brachii (TB),p= 0.047.Conclusion:According to the results it can be deduced that lactic resistance training with pas-sive rest and with active rest do not influence the muscle response if we compare both trainings.Only one of the Tc values changes, while the latissimus dorsi muscle also shows changes in Td.
