Physical and phisiological profile of rugby juvenile athletes
Abstract
Rugby is an intermittent sport with high demands on power, strength and speed capabilities. These specific requirements demonstrate the importance of respecting the functional demands and physical characteristics between backs and forwards athletes. The objectives of the study were 1) to describe the physical performance, structure and body composition characteristics of youth Rugby athletes and 2) to compare the athletes according to their tactical positions. Eight athletes (16 to 18 years old) from Guarapuava-Paraná-Brasil participated, grouped according to game positions, four in the forwards position and four in the backs position. Athletes were submitted to anthropometric measurements to estimate the percentage of fat, somatotype and motor tests to determine physiological parameters. The analysis was performed using the Shapiro-Wilk test and the Mann-Whitney U test. The results revealed significant differences for body mass and fat percentage of forwards compared to backs (88.5±15.7kg and 67.2±10.1kg; 22.5±5.3% and 16.4±1, 0%, respectively). While the athletes' physical profile showed a predominance of muscle mass (endomesomorph), no differences were found between the positions for the physiological variables. We conclude that the athletes of the present study have similar characteristics between the tactical positions described in other studies, however they demonstrate marked disadvantages in the fat content that could interfere in a better motor performance.
