HIIT With an Eccentric Hamstring Exercise Program in Futsal Players

The training program in the HIIT+NC group was divided into the following parts: i) warm-up (10 minutes); ii) HIIT (25 minutes) consisting of a circuit of eight exercises; iii) Nordic curl exercise (10 mintues); and iv) stretching.

The HIIT group performed the same exercises in the warm-up, HIIT and stretching sections as the HIIT+NC group, however, they did not perform the NC eccentric exercises.
