AI written summary

Horizontal deceleration is a crucial locomotor skill in multi-directional sports, enabling athletes to reduce speed rapidly, change direction efficiently, and gain tactical advantages. Research shows that strong braking ability is linked to better offensive and defensive performance, higher-quality decision-making, and reduced injury risk. Despite its importance, few evidence-based guidelines exist for developing this quality.

The authors introduce the Braking Performance Framework, which offers practitioners a structured approach to enhance deceleration ability by targeting both braking force control and braking force attenuation.

Braking Force Control

This refers to an athlete’s ability to position the body effectively (e.g., centre of mass behind the lead foot, negative shin angle) and coordinate limbs to generate high horizontal braking forces. It also includes perceptual–cognitive components: the ability to brake in response to game cues and changing environments.

Braking Force Attenuation

Deceleration exposes athletes to extremely high impact forces—often greater than sprinting or jumping. Tendons and muscle–tendon units must handle and distribute these loads to minimise tissue damage. Improving a player’s “damage-resistance” is crucial for preventing ACL injuries, hamstring strains, and overuse issues.

The Braking Performance Framework

The framework progresses from local structural loading to global sport-specific braking actions, organised into three exercise categories:

a. Braking Elementary Exercises

Focus: strengthening tissue capacity and neuromuscular control
Methods include:

• High eccentric loading
• Pre-planned decelerations (no COD)
• Assisted braking steps
• Eccentric yielding isometrics
• Eccentric landing control

These target eccentric strength, tendon stiffness, shock absorption and dynamic stability.

b. Braking Developmental Exercises

Focus: increasing braking force in less time (“tall-thin braking impulse”)
Methods include:

• Fast eccentric loading (plyometrics, drop jumps, eccentrically-focused lifting)
• Pre-planned decelerations with COD
• Assisted horizontal decelerations
• Fast concentric loading (“overspeed” work)
• Overcoming isometrics
• Oscillatory isometrics

These improve rate of force development, joint angular velocities and coordination.

c. Braking Performance Exercises

Focus: integrating braking skills into fully sport-specific contexts
Examples:

• Unanticipated decelerations
• COD under pressure
• Game-based stimuli (SSG, MSG, LSG)

These link the physical qualities to tactical and perceptual decision-making.

Key Takeaways

• Horizontal deceleration ability directly impacts performance, tactical effectiveness, and injury risk.
• Training should address both force production (braking force control) and shock absorption (braking force attenuation).
• A mixed-methods approach combining eccentric strength, plyometrics, technical braking drills, COD work, and game-like scenarios is optimal.
• Progression should move from isolated tissue-focused exercises → to fast/reactive neuromuscular training → to sport-specific perceptual–cognitive drills.
