The fatigue is not simple to be evaluated and it is most commonly referred to a reduced capacity for maximal performance. It is a parameter that constantly affects the performance of runners and there are no wearable devices on the market enable to calculate it. The purpose of the study is to find a correlation between the parameters of the gait cycle and fatigue. An inertial sensor had been placed on the dorsum of the right foot during two 5-minute running trials in an high-intensity intermittent exercise (HIIE) protocol. The parameters of the gait analysis have been calculated and studied according to the heart rate in order to define a fatigue index. A linear regression algorithm was used to establish this relationship. The mid-high$R^{2}$indicates a good regression. Therefore it suggests us that it is possible to compute the FI using the only gait parameters without the use of an HR band.
