This early sex difference presumably influences, and interacts with, gender-specific socialization processes to amplify sex differences as the child ages. (24, p. , differential levels of fetal activity). On this point, the published data have not provided a consistent picture. 33, which did not differ significantly from zero (43). However, this included only six studies, which was felt to be inadequate for answering the question. Almli and others found that males were more active than females when they made longitudinal observations of fetal leg movements per minute by ultrasonography at 30, 34, and 37 weeks gestation (3).

Biological maturation status was assessed by estimated age of peak height velocity. When findings were adjusted for maturation, the expected effects of age on activity levels by sex were eliminated. Other studies have consequently confirmed these findings (34). The reports supported the concept that differences in level and rate of biological maturation contribute to sex differences (by chronological age) during the growing years. In this way, sex differences in physical activity during childhood and adolescence are explained by the differential tempo of sexual maturation in males and females, pointing to a biological rather than a sociocultural influence.

Novak and others contended that “wheel-running behavior represents factors in addition to rodents’ tendency to be physically active, engaging additional neural and physiological mechanisms which can then independently alter energy balance and behavior” (107, p. 1001). How such stereotypic behavior and habitual spontaneous activities might be differentiated by biologic control is not understood. Finally, Meijer and Robbers performed an interesting experiment in which a 24 cm diameter running wheel (along with camera, motion sensor, and food tray) was placed in an outdoor environment to determine if rodents would engage in wheel running in their natural environment (102).
