The study examined how different exercise-to-rest ratios impact repeated sprint ability (RSA) training in female soccer players, comparing three types of sprints: straight, shuttle, and those with directional changes.
Fifteen trained female soccer players participated, with their fatigue levels measured using an index of fatigue (IF%) and blood lactate concentrations analyzed post-exercise.
Results showed a 5% decrease in performance over time but no significant differences in fatigue levels across the sprinting types with the ratios tested; however, blood lactate levels varied significantly, suggesting the ratios could be effective for RSA training in women.
