[Geometric and dynamic characteristics of hockey sticks in regard to their performance]

The hockey stick can be used for numerous tasks such as shooting, dribbling, receiving and executing passes, stick handling, etc. The purpose of this study was to evaluate the geometrical and dynamic characteristics of hockey sticks in order to identify those which contribute most significantly to its longevity and durability. The characteristics of 14 models of hockey sticks were measured according to the procedure describes by Roy and Doré (1975). To evaluate the longevity of the stick, 45 Midget AA were selected. Each one was given two sample sticks selected randomly. They were to use those sticks in practices and in game situations. Fifteen adult players were selected to evaluate the durability of the stick. Each one received four sample sticks. They had to execute as many slap shots as they could until the stick broke. This work confirmed a previous study of Roy and Doré 1975) which demonstrated a high level of homogeneity in the geometrical characteristics, but a high heterogeneity in their dynamic characteristics. This study revealed also that the longevity and durability measures showed a high level of variability. Through a multiple regression analysis, it was shown that the width and thickness of the handle as well as the rupture coefficient and the module of rigidity of the handle (in a plane parallel to the blade) were four variables contributing significantly to the longevity of the stick.
