Hip and knee positions during the curling delivery

Abstract

The primary purpose of this study was to determine the relationships between trunk, thigh, hip and knee measurements from the forward slide phase of the curling delivery. The second purpose of this study was to determine the relationship between hip goniometric measurements and hip measurements from the forward slide phase of the curling delivery. The third purpose of this study was to establish normative range of motion data for the trunk, thigh, hip and knee during the forward slide phase of the curling delivery. Sixty junior-level curlers (30 females, 30 males) aged 13-21 participated in active hip extension goniometric measurements and motion analysis of hip and knee positions during the curling delivery. A strong relationship was found between absolute trunk and relative hip measurements from the curling delivery. A fair relationship was found between absolute thigh and relative hip measurements from the curling delivery, along with absolute hip and relative knee measurements from the curling delivery. Gender differences were found for the absolute trunk and relative hip measurements from the curling delivery. No relationship was found between relative hip extension goniometric measurements and hip measurements from the curling delivery. Absolute trunk extension measurements from the curling delivery were 37.2" and 27.5" for female and male subjects. Absolute thigh measurements and relative knee measurements from the curling delivery were 33" and 3 1" for both genders. Relative hip measurements from the curling delivery were -3.9? and 5.7? for female and male subjects.
