To determine magnitudes of difference, and degree of variability, in standard anthropometric and fitness characteristics of national level men and women Rugby Sevens players. National Sevens squad players (males n=32, age 22 + or - 3 years; height 1.82 + or - 0.06 m; mass 90 + or - 8 kg; females n=32, age 25 + or - 6 years, height 1.68 + or - 0.06 m; mass 70 + or - 9 kg; mean + or - SD) age were tested during routine training camps. All testing was conducted indoors on a synthetic running track after instruction, warm-up and familiarization with each test protocol. Male players had ~40% more lean mass and 40% lower skinfolds than the women. Speed (40 m sprint time and maximal running velocity Vmax) was only ~10-20% faster for the Men, while lower body power and momentum (mass x Vmax) were 40-50% higher in Men. The Women were more than twice as variable (ratio of CV <0.4) in endurance fitness than the Men.
