Abstract

Introduction: Due to the lack of studies describing and analysing the isometric force profile in Trampoline and its relationship to athletic performance, it was decided to conduct a cross-sectional, comparative and correlational study of this kind with Spanish trampolinists. Method: Sample composed of 60 national elite trampolinists, grouped by competitive category into 4 groups: 1) under-15 boys (n=23; 11.95 ± 1.79 years), 2) under-15 girls (n=9; 11.44 ± 1.23 years), 3) men (n=18; 20.72 ± 4.66 years), 4) women (n=10; 16.1 ± 2.02 years). Measurement by isometric dynamometry using load cells (Faculty of Physical Activity and Sports Sciences Strength Monitoring system), obtaining absolute and relative isometric strength in flexion and extension of knees, trunk, elbows, shoulders and hand grip. Comparisons between groups and correlations of strength with degree of difficulty score. Results: Numerous significant correlations between absolute strength and difficulty; shoulder extensor strength correlates significantly with difficulty in all groups; significant increase in absolute strength with age but not in relative strength. Conclusions: Higher isometric strength values in the adult groups compared to under-15s justify their separation in competition; the results obtained could be used in the design of a test for the selection of talent in diving.
