Aerial and Terrestrial Patterns: A Novel Approach to Analyzing Human Running

Biomechanical parameters are often analyzed independently, although running gait is a dynamic system wherein changes in one parameter are likely to affect another. Accordingly, the Volodalen((R)) method provides a model for classifying running patterns into 2 categories, aerial and terrestrial, using a global subjective rating scoring system. We aimed to validate the Volodalen ((R)) method by verifying whether the aerial and terrestrial patterns, defined subjectively by a running coach, were associated with distinct objectively- measured biomechanical parameters. The running patterns of 91 individuals were assessed subjectively using the Volodalen ((R)) method by an expert running coach during a 10-min running warm-up. Biomechanical parameters were measured objectively using the OptojumpNext ((R)) during a 50-m run performed at 3.3, 4.2, and 5 m center dot s(-1) and were compared between aerial- and terrestrial- classified subjects. Longer contact times and greater leg compression were observed in the terrestrial compared to the aerial runners. The aerial runners exhibited longer flight time, greater center of mass displacement, maximum vertical force and leg stiffness than the terrestrial ones. The subjective categorization of running patterns was associated with distinct objectively- quantified biomechanical parameters. Our results suggest that a subjective holistic assessment of running patterns provides insight into the biomechanics of running gaits of individuals.
