This past month, the Coaching Association of British Columbia (also known as CoachesBC) has published a revised copy of a guide to coaching female athletes that was first published in 2001:
[This guide] is designed as a reference for coaches of female athletes. The publication provides information about the needs, interests and experiences of female athletes to support coaches in fostering their physical, mental, emotional and social potential. Regardless of the gender of the coach, he or she must recognize the specific needs of their athletes and understand the unique characteristics of female athletes.
This 16-page guide, available as both a PDF file and in hard copy, outlines the many differences between boys and girls in their emotional, physiological, and cognitive development. In addition to the wealth of material presented on coaching girls and the need for gender-specific activities, an important point for curling is the increased risk of significant ACL (Anterior Cruciate Ligament) injuries to girls, which can be mitigated through warmup and stretching activities before taking to the ice.
I have placed a permanent link to this guide on the Resources page.
