Description Sprinting with resistance (RSS) appears to be a suitable method for improving sprinting performance in the acceleration and maximum speed phases. The research focused on testing speed-strength capabilities, sprinting performance over 20 m at different resistance sizes, by finding the decrease in velocity (Vdec), maximum (Fmax) and average (Favg) horizontal force production (Progressor 300, Tindeq, NOR) at specific resistance. Subjects (n=10; adult males with previous resistance sprint experience) completed an isometric deadlift from mid-thigh (IMTP) and a countermovement vertical jump (CMJ) on day 1. After 48 hours, a no-resistance sprint (URS) and resistance sprints of 8 oz (~0.2 kg), 12 oz (~0.34 kg), and 2 lb (~0.91 kg) were performed using the Speed Trainer (Exergenie, USA). A correlation between CMJ and speed tests was found. Similarly, IMTP was correlated with speed tests, along with RSS 2 lb (r = -0.58; p = 0.077). Tracking the Vdec relationship showed the highest correlation between Vdec 8 oz and URS 20 m (r = -0.57; p = 0.084). Vdec 2 lb was the only one correlated with IMTP (r = -0.26; p = 0.470). IMTP values showed a strong relationship with Fmax at 2 lb resistance (r = 0.45; p = 0.191). The results demonstrate the relationship of strength abilities with speed parameters and horizontal force in sprinting.
