This study compared the effects of two training programs: extreme sided-games of 1v1 vs. medium-sided games of 5v5 in 20 male regional-level young soccer players during 4 weeks. Both groups improved countermovement jump (CMJ), and final velocity in the 30-15 Intermittent Fitness test (VIFT), but only the 1v1 group improved the 5-0-5 test 180 degrees change-of-direction time.

This study retrospectively evaluated injury and workload data (total distance, high-speed distance, accelerations, player load, and average velocity) for all players (n=23) of an NCAA men’s soccer team during one 18-week season. Trainings/games with injuries had higher acute (last 3 days) workloads, lower chronic (last 28 days) workloads, and higher ACWRs for all 5 workload variables. Risk factors for injury included a low chronic workload for total distance (OR 7.23) and an ACWR >1.4 for accelerations (OR 4.34). This suggests that methods of decreasing injury risk in soccer can consider maintaining a consistent chronic workload for total distance and avoiding elevations in the ACWR for accelerations.
