Assessment of inspiratory muscle reserve capacity by the tension-time index method

Objective. Effects of exhaustive exercise on functional outcomes of inspiratory muscles were investigated in this study. Materials and Methods. Power and timing parameters of muscle contraction as well as the tension-time index (TTI) were calculated. A specially designed experimental device model which assessed the respiratory muscles functional state was used during the trial. Results. It was shown that exhaustive exercise resulted in the decrease of functional reserve of inspiratory muscles. After exhaustive exercise maximal inspiratory pressure decreased by 9 % (p
