“…To our knowledge, however, information about inertial parameters of segments is not available for toddlers between 15 and 36 months, which is the critical age for the development of important motor skills such as walking and running. Several researchers emphasized the potential importance of anthropometric characteristics for the development of locomotion (Shirley, 1931;Garn, 1966;Erbaugh, 1984;Thelen et al 1989). Therefore, systematic analyses of the relationship between motor development and specific measures of size, body proportions, and body composition during early childhood are needed (Malina, 2004).…”
