We have studied skilled human locomotions in sports gymnastics by measurement and analysis of ground reaction force and myoelectric signals. Assuming the quality of performance to be a skill level criterion acquired signals were mathematically analyzed via basic signal processing and cross-correlation methods. The study of backward somersault yielded quantitative criteria of performance, proposing an original measure-an inter-muscular cross-correlation function. Besides motor learning, the quantification of movement skill introduced here also relates to possible applications in biocybernetics, robotics and rehabilitation medicine.
