Armstrong, N., Welsman, J. R., Kirby, B. J., & Williams, C. A. (1998). Longitudinal changes in Wingate Anaerobic Test performance. Medicine and Science in Sports and Exercise, 30(5), Supplement abstract 1729.
Boys (N = 70) and girls (N = 62) were assessed at ages 12.2 and then 13.2 years on a braked cycle-ergometer anaerobic test for 1-sec peak power and mean power over 30 seconds.
Peak power was significantly greater after one year of growth. Both groups improved in mean power but a significantly greater improvement was recorded for boys. Post-exercise blood lactates were similar for the genders.
Implication. Mean power increases significantly more for boys than girls between 12 and 13 years of age.
