United States Under-19 Rugby-7s: Incidence and Nature of Match Injuries During a 5-year Epidemiological Study.

Background: There is a lack of injury data for the new Olympic sport of Rugby-7s, particularly for involved youth.

Objective: To determine injury rates and characteristics for players participating in U.S.

Injury Profile of American Women's Rugby-7s.

Purpose: The objective of this study is to determine incidence (injuries/1000 playing hours (ph)), severity (days of absence), and cause of match injuries in US women's Rugby-7s.

Methods: We performed a prospective epidemiological study (2010-2013) of injury of 3876 under-19 to elite/national female Rugby-7s players (nonelite = 3324, elite = 552) on 323 teams (nonelite = 277, elite = 46), applying methodology and injury definitions compliant with the international consensus statement on rugby research. Injuries occurred in USA Rugby-sanctioned tournament series: USA Rugby Local Area (2010), Territorial Union (2011-2013), National and All-Star Sevens Series, and USA Sevens Invitational (2011-2012) and Collegiate Rugby Championships (2012).
