Abstract: The objective was to analyze the changes in the horizontal force-velocity profile (HFVP) during the execution of repeated sprinting. Methods: Seventeen first-division Chilean soccer players completed a repeated sprint protocol consisting of eight sprints of 30 m with 25-s pauses between repetitions. The behavior of HFVP variables in each attempt was recorded from video recordings and analysis in the MySprint ® application. Results: Differences ( p < 0.05) were found between sprints in the following: time (T), starting from sprint 5 (F = 35.6; η 2 p = 0.69); theoretical maximum speed (V0), starting from sprint 4 (F = 29.3; η 2 p = 0.51); maximum power (PM), starting from sprint 5 (F = 17; η 2 p = 0.52); rate of decrease in force index produced at each step (DRF), starting from sprint 1 (F = 3.20; η 2 p = 0.17); and RF10, starting from sprint 1 (F = 15.5; η 2 p = 0.49). In comparison, F0 and RFpeak did not present any differences ( p > 0.05). Conclusion: The HFVP variables more sensitive to the effects of fatigue induced by an RSA protocol are those associated with the production of force at high speeds, being V0, DRF, and Pmax, while those that contribute to the generation of force at the beginning of the sprint, F0 and RFpeak, do not present essential variations.
