Complex network model indicates a positive effect of inspiratory muscles pre-activation on performance parameters in a judo match

Abstract This study investigated the effects of inspiratory muscle pre-activation (IMPA) on the interactions among the technical-tactical, physical, physiological, and psychophysiological parameters in a simulated judo match, based on the centrality metrics by complex network model. Ten male athlete...
