The muscle mass of lower limbs not a good predictor of performance in the vertical jump

Abstract

Currently there are few studies that relate the muscle mass of lower limbs (MMLL) and vertical jump (VJ). Therefore, the aim of this study was the association between the MMLL and VJ in individuals who practice bodybuilding. Ten men (age 17,40±2,32 years old, size 172,10±5,76 cm and a body weight of 79,13±19,54 kg) practitioners of bodybuilding participated voluntarily. To estimate the MMLL was used a validated equation and applied the jump CMJ and SJ. The statistical analysis was carried out in PSPP for Windows 7 to apply the test of Shapiro-Wilk normality and Pearson correlation coefficient. The data obtained showed normal distribution (p>0,05), likewise the MMLL evidence a negative and significant relationship with CMJ (r = -0,73; p = 0,02), and also with SJ (r = -0,73; p = 0,02). In conclusion, the MMLL is not a good predictor of performance in the VJ.
