Abstract

Background and Purpose: In 1998, curling was awarded medal status in Olympic competition, and since then, the popularity of the sport has dramatically increased. This has led to increased skill level and competition among curlers. However, there is currently limited research analyzing the curling delivery. The purpose of this study is to provide scientific information explaining delivery characteristics of curlers while executing draw and take-out shots. This study concentrated on the force generators within the delivery and the mechanisms used to control and determine weight.

Methods: Three healthy subjects participated in this motion analysis study. Subjects were video taped completing three successful draw and three successful take-out shots using there normal curling delivery. Eighteen successful deliveries \\'ere analyzed in this study. An independent t-test was used for analyzing the means of rock height, subject COG linear velocity, and rock linear velocity. In addition, a visual comparison of angular velocities occurring at the hip, knee and ankle was made between draw and take-out deliveries.

Results: When comparing the two deliveries, two of the three subjects showed significant increases in rock height and rock linear velocity. No subjects showed significant increases in COG linear velocity. Two subjects seemed to show large increases in angular velocities when comparing the deliveries.

Conclusion: No one consistent method of weight control \vas used by the three subjects, and weight control seems to be due to individual preference.
