The Differential Effects of Two Complementary Sprint-Based Training Programs on Sprint Performance in Professional Female Soccer Players

This research investigated the effects of two 12-week sprint training programs, traditional sprint training (TST) and modified integrated sprint training (MIST), on the sprint performance and match running performance of professional female soccer players. Forty-five players from two professional teams were assigned to either the TST group or the MIST group based on availability. Each group participated in two sprint sessions weekly, supplementing their regular in-season schedule. Physical performance was measured using 30-m sprint tests, including 5-, 10-, and 30-m splits, and the Yo-Yo Intermittent Recovery Test Level 2. Match demands were assessed using GPS technology during four official matches, concentrating on very high-speed running distances (>23 km/h) and the number of sprints. Both groups demonstrated significant improvements in most metrics ( p ≤ .05), except for maximal oxygen uptake in the TST group ( p = .328, effect size = 0.09). Comparative analysis revealed that the TST group achieved significantly greater improvements in sprint times ( p = .017–.000, effect size = 0.77–1.74), while the MIST group showed superior enhancements in match sprint metrics ( p = .016–.000, effect size = 0.66–1.89). No significant differences in maximal oxygen uptake were observed between groups. These findings indicate that both training methods are effective, with TST being more advantageous for linear sprint development while MIST is more effective for improving on-field sprint performance. Coaches should consider the specific needs and performance objectives of each player when selecting training strategies.
