Relaciones entre diversas manifestaciones de la fuerza en diferentes grupos musculares en adultos jóvenes
Fernández Ortega, Jairo Alejandro | 2017-01
Strength and muscular power have been evaluated in the sports or health context to determine their degree of development, however evidence of the relationship between these two muscular manifestations is limited and contradictory. The aim of the study was to identify the relationship between different manifestations of strength and muscular power. Thirty-seven men and thirteen women aged between19 and 23 years participated in this study. We assessed the power and the isometric and dynamic strengthin upper and lower limbs; and size, weight and body mass index (BMI) were measured. No significant differences were identified between prehensile force (PF) values of left and right hand (p-value<0.414). The maximum power of upper limbs (PMMS) was obtained with a4.0% load. Good correlations were observed (0.608**-0.869**) between: PF and maximum power of upper limbs and lower limbs (PMMI); the maximum isometric force of the lower train (FMII) and the mean power propulsive phase in chest press (PMPP); the maximum force in half squat (1RMS) with maximum force in chest press (RMP), the mean power propulsive in half-squat (PMPS) and the mean propulsive velocity in the chest press (VMPP); the RMP with PMPP, PMMS, PMMI and PMPS; the PMMS with PMMI, PMPS and PMPP; the PMMI with PMPS and the VMP in half squat (VMPS); the counter movement jump (CMJ) with squat jump (SJ); the VMPS with PMPS; the PMPSP with PMPP; the PMMS with CMJ; the VMPP with PMMS; and finally, the PMPP with CMJ.
