Mixed Training Programs Applied to Young Soccer Players: Effects on Speed-Power Abilities

Area of Science:

• Sports Science
• Exercise Physiology
• Soccer Performance

Background:

• Young soccer players require optimized training for physical performance.
• Strength-power-speed protocols are crucial for developing athletic capabilities in soccer.
• Comparing training methodologies is essential for evidence-based practice.

Purpose of the Study:

• To compare the effects of traditional and multidirectional training protocols on soccer players' physical performance.
• To evaluate adaptations in strength, power, linear speed, and change-of-direction (COD) ability.
• To identify which protocol yields superior results for specific physical attributes.

Main Methods:

• Twenty-three under-20 soccer players participated in a 4-week training intervention.
• Two groups were formed: traditional (TRAD) focusing on vertical power and linear sprints, and multidirectional (MULTI) including horizontal power and COD drills.
• Physical performance was assessed pre- and post-training using jump, sprint, and COD tests.

Main Results:

• Both TRAD and MULTI protocols significantly improved sprint velocity and specific power outputs (jump-squat, hip-thrust).
• The TRAD group showed greater improvements in squat jump height.
• The MULTI group demonstrated more meaningful improvements in zig-zag (COD) velocity.

Conclusions:

• Both training protocols induce similar overall physical adaptations in young soccer players.
• The MULTI protocol appears more effective for enhancing COD ability.
• The TRAD protocol may be preferable for maximizing vertical jumping performance within short pre-season periods.
