3D ANALYSIS OF THE BODY CENTRE OF MASS IN ROCK CLIMBING

The purposes of this study were: to test an experimental protocol for the analysis of basic rock climbing movements; to find whether it is possible to identify a golden standard strategy for the proposed movements. 12 recreational climbers were involved in the study. Each subject climbed a 3m horizontal shift followed by a 3m ascent. Climbers could choose their own style, their preferred speed and holds. Acquisition were performed using an optoelectronic system with reflective passive markers, attached to the subjects' joints. Results show that two main climbing strategies can be identified: the first preferring agility over force and the second preferring force over agility; we also found out that, good climbers try to minimize power, during the whole trial. These results would be our starting point for new experimental sessions

QUANTITATIVE ANALYSIS OF HIGH JUMP STYLES

The purpose of this study is to investigate the relationship between the kinematics and the dynamics in the elite high jumpers. The analysis was based on an accurate anthropometrical model of the body and on the kinematics data obtained through optical motion capture in an indoor training session. The measure of the angular momentum has given suggestions on how to improve the efficiency of the gesture. The analysis of the kinematics coordination and of the inter-trial variability suggest that athletes should focus more either on the kinematics or on the dynamics. From these data, the angular momentum and the kinematics variability do not appear to be correlated
