This study shows that physically less active children are shorter and have shorter feet. In analogy to the "muscle bone unit", we propose a "muscle epiphyseal unit" which regulates local bone growth as long as epiphyseal plates are still open.
Analysis of three-way interactions provided new theoretical insights into the protective effects of mutuality and preparedness and demonstrated conditions under which caregivers are at increased risk for negative outcomes.
