A study was conducted to analyze the jump capacity jump in Spanish trampoline gymnasts and compare different categories with each other, through a descriptive cross-sectional design. The sample consisted of 60 trampoline gymnasts belonging to the national elite, grouped by age and sex in different competitive categories, differentiating finally 4 groups: age group male Under-15 (GM1 n = 23; 11,95 ± 1,79 years) and female (GF1 n = 9; 11,44 ± 1,23 years); age group male Absolute (GM2 n = 18; 20,72 ± 4,66 years) and female (GF2 n = 10; 16,1 ± 2,02 years). To assess the jump capacity was measured height in the SJ and CMJ, through contact platform; additionally mechanical power was estimated according to the formula of Sayers et al. (1991). Significant differences were found (p<0,05): GM1-GM2, higher results in GM2 in CMJ height, power of SJ and CMJ; GF1-GF2, higher values in GF2 in power of SJ and CMJ; GM1-GF1, higher values in GM1 in height and relative power of SJ; GM2-GF2, higher results in GM2 in all variables. These results are consistent with the characteristics of sex and maturational development, supporting separation for competition in male and female categories and age groups Under-15 and Absolute; suggest further a different jump capacity in trampoline gymnasts compared with gymnasts of another specialties
