Comparison of lower limb power tests by two indirect methods in volleyball players under-18 category/Comparación de pruebas de potencia de miembros inferiores por dos métodos indirectos en voleibolistas categoría sub-18

Abstract

The vertical jump test is very interesting as a test physical in modern volleyball to assess the power of the legs, since in this way the physical trainer can plan a strength-speed program with the intention of improving their physical performance on the game field. Volleyball is a sport that is characterized by short duration and high intensity game actions, alternated by short periods of rest. This suggests the need to develop great power in volleyball female players, fundamentally in the lower limbs, aspects that were evaluated on ten volleyball athletes in the sub-18 category of the National Volleyball School by indirect methods Lewis and Harman, to whom a cross-sectional study was carried out in the stage of general physical preparation. The objective of this work was to compare the power levels of the lower limbs by both tests in a period of six weeks. As empirical methods, measurement and indirect tests were used to evaluate jumping power. Satisfactory results are obtained in both tests, fundamentally after subjecting the athletes to a system of exercises that show the Harman power values with a higher level of information for the coach, since in this it takes into account the action of the gravitational acceleration that must be overcome in the take-off phase. Based on the results, individual suggestions for the training of these athletes were provided.
