Game-Based Versus Linear Sprint Training in Male Soccer Players

A 12-Week Randomized Controlled Trial Evaluating the Time-Course Effects of Once-Weekly Game-Based Versus Linear Sprint Training on Soccer Performance and Hamstring Strength in Amateur Players During the Competitive Season

This randomized controlled trial investigated the effects of two different sprint training approaches on physical performance in male amateur soccer players during the competitive season. The study aimed to determine whether once-weekly game-based sprint training or linear sprint training could improve sprint performance, change-of-direction ability, hamstring strength, and maximum running velocity achieved during official matches.

Thirty-six male amateur soccer players were randomly assigned in a 1:1:1 ratio to one of three groups: the Game-Based Sprint Group, the Linear Sprint Group, or the Control Group. Participants in both sprint training groups completed one additional sprint training session per week for 12 weeks while continuing their regular soccer training and competition schedule. The Linear Sprint Group performed maximal 40-meter linear sprints, whereas the Game-Based Sprint Group performed soccer-specific sprint activities that included running, ball involvement, and technical actions. The Control Group continued regular soccer training without an additional sprint-specific intervention.

Sprint performance, change-of-direction performance, and right and left hamstring strength were assessed at baseline, Week 6, and Week 12. Maximum running velocity was also monitored during official matches throughout the 12-week study period. The study was designed to compare how the two sprint training approaches affected performance over time and whether changes observed during standardized testing were also reflected in maximum running velocity during competitive matches.

Inclusion Criteria:

• Male amateur-licensed soccer players.
• A minimum of 5 years of regular soccer training experience.
• Participation in organized soccer training at least 5 days per week.

Exclusion Criteria:

• A serious musculoskeletal injury within the previous 6 months that could interfere with participation in the training intervention or performance assessments.
• Musculoskeletal surgery within the previous 6 months that could interfere with the study outcomes.
