EFECTOS AGUDOS DEL ESTIRAMIENTO ESTÁTICO Y DE LA FACILITACIÓN NEUROMUSCULAR PROPIOCEPTIVA EN EL DESEMPEÑO DEL SALTO VERTICAL DE TENISTAS ADOLESCENTES

Introduction: Traditionally the flexibility exercises have been enclosed as part of the warm-up that precedes a tennis match. However, a controversy exists if the intensity of execution of flexibility would have influence on the athletic performance. The objective of the present study was to verify the acute effect of the static stretching and the proprioceptive neuromuscular facilitation (PNF) on the performance of jump in adolescent tennis players. Materials and Methods: To participate on the experiment it was chosen nine young tennis players, being four of feminine sex and five of the masculine sex, with average age of 14.4 years-old, participants of a tennis school. The group had a warm-up participating of the activities of the tennis lesson and then they executed the jumps. After that a session of trainings of flexibility was carried through immediately after performing new jump. Results: After statistical treatment, the results did not present significant change in the height of jump (p=0.66>0.05) between the tests and post test and static and PNF stretching. Discussion: Athletes, who directly need the muscular strength for power generation as the tennis players, seem to not being benefited with exercises of passive stretching or PNF preceding the specific exercise.
