ABSTRACT

A total of 36 elite rugby players with a mean of age, height, weight, body mass index and fat percentage: 26 ± 2.8 years, 180.9 ± 7.8 cm, 98.3 ± 15.6 kg, BMI 28.6 ± 4, and 14.21 ± 3.02 for % of fat respectively, tested at ½ peak power squat (AP), speed at 10 and 40 m (T10, T40), repeated sprint ability (RSA), test jumps (SJ & CMJ), and incremental test on a treadmill, with the following results: AP (1223.69 ± 161.29 watts), T10m (1.71 ± 0.12 s), T40 (5.42 ± 0.29 s), RSA best (7.51 ± 0.35 s) RSA mean (7.81 ± 0.37 s), SJ (33.30 ± 4.94 cm) CMJ (43.70 ± 5.38 cm), and VO2max (45.6 ± 5.1 ml · kg-1 · min-1). Significant differences were found between the forwards and backs for the AP, 40 m, RSA mean, RSA best and VO2max. There is a significant correlation between the RSA mean vs. VO2max test (r = -0.822, p <0.01); RSA best vs. T10 and T40 (r = 0.623 and 0.810, p <0.01 respectively); T10 and T40 (r = 0.876, p <0.01); SJ vs. T10, T40 m and RSA best (r = -0.584, -0.691 and -0.570, p <0.05, p <0.01 and p <0.05 respectively) and CMJ vs. T10, T40 m and RSA best (r = -0.575, -0.702 and -0.630, p <0.05, p <0.01 and p <0.05 respectively). Only backs had a significant correlation between SJ vs. AP (r = 0.93, p <0.01), and CMJ vs. AP (r = 0.85, p <0.01), but there are significant correlations between power output relative to body weight (POWREL) and SJ & CMJ (r = 0.689 and 0.758, p <0.01), among the whole group. There are also correlations between POWREL and T10, T40, RSA best and RSA mean (r = -0.628, -0.758, -0.72 and -0.74, p <0.01). In conclusion, through the RSA test proposed, we have collected data that could allow us to estimate the conditional profile of an elite rugby Spanish player. The ½ squat exercise is a possible predictor of performance in sprint and RSA.
