Abstract: The aim of the study was to assess physical performance during competition in elite youth rugby players with respect to their specific position on the field (backs vs. forwards). Twenty two elite male under-19 rugby union players voluntary participated in the study (13 forwards and 9 backs). Players’ activity profiles were assessed using Global Positioning System technology during three rugby union friendly matches. Players’ heart rates were also recorded. No significant differences were found between forwards and backs in total distance covered, average speed, or maximum and average heart rate. Backs covered significantly greater running distance than forwards at 0 to 6 km. h-1 (35.5±4.1 vs. 28.7±4.0 m·min-1; p<0.05) and greater distance at speeds of 20 km. h-1 and greater (7.5±2.8 vs. 2.6±2.2 m·min-1; p<0.05) whereas forwards covered greater distance at 6 to 12 km. h-1 (26.6±4.8 vs 19.9±4.8 m·min-1; p<0.05) and at 12 to 14 km. h-1 (8.8±2.7 vs. 6.5±2.0 m·min-1; p<0.05). Backs performed more very high-intensity runs than did forwards (0.33±0.13 vs. 0.14±0.10 no·min-1; p<0.05). In conclusion physical demands during the match differed between backs and forwards with backs performing a greater number of high intensity efforts than did forwards.
