Understanding Deceleration and Acceleration
- Deceleration is crucial for effective change of direction in athletic movements.
- High correlation between fast eccentric force (deceleration) and greater concentric force (acceleration).
- Training to stop quickly in one direction aids in moving efficiently in another.
Key Attributes for Agility and Directional Change
- Single-leg Strength: Essential for stabilizing during directional changes.
- Ability to land, decelerate, and maintain balance on one leg is crucial.
- Stability: Must minimize joint sway and maintain proper alignment.
- Focus on knee (valgus and varus) and hip alignment.
- Deceleration Training: Conducted through various drills focusing on reducing speed efficiently before changing direction.
- Single-leg Strength: Essential for stabilizing during directional changes.
Training Methods for Deceleration
- Eccentric Training: Focus on high rates of force production through eccentric movements.
- Iso Holds: Control force output at specific joint angles.
- Speed Drills:
- Start at 50% max velocity, stop within 3-4 steps, and progress to faster speeds and fewer stopping steps (e.g., stopping at 3/4 speed in 5 steps).
- Progress to full speed while maintaining stability during deceleration and directional changes.
Mechanics of Change of Direction
- Appropriate body position (e.g., lowering center of mass) is essential for force generation.
- Feet must be positioned correctly to leverage ground reaction forces.
- Kinetic chain efficiency impacts acceleration and deceleration capabilities.
- Appropriate body position (e.g., lowering center of mass) is essential for force generation.
Role of Visual Focus and Arm Movement
- Arm movement assists in directional changes and can influence effective stopping mechanisms.
- Visual focus directs the body’s movement and stability during rapid changes in direction.
Drill Classification in Agility Training
- General vs. Special Drills:
- General drills focus on single plane movements and mechanics; special drills are sport-specific and incorporate multiple movements.
- Open vs. Closed Drills:
- Closed drills are predictable and help in understanding distance for deceleration.
- Open drills require reactive abilities and are more sport-specific, simulating game situations.
- Continuous vs. Discrete Drills:
- Continuous drills have no clear endpoint and may involve varied movement patterns.
- Discrete drills have a defined end and specific tasks (e.g., sprints followed by stops).
- General vs. Special Drills:
Importance of Mobility in Agility Training
- Mobility allows proper positioning and mechanics during movement.
- It is crucial for handling forces during athletic performance (e.g., how much force can be applied through a given range of motion).
- Consider how tight hips and ankles can impact overall movement quality and injury risk.
- Mobility allows proper positioning and mechanics during movement.
Practical Application and Progression
- Start simple before advancing to complex drills. Assess mechanics to identify skill gaps before introducing advanced movements.
- Monitor force applications and ensure reliability across different training methods (e.g., sled push mechanics).
Equipment and Training Devices
- Use of assistive devices (e.g., sleds) can enhance force outputs but must align with specific training goals.
- Important to understand the purpose and adjust resistance based on the goal (max strength vs. rate of force development).
Recap of Technical Concepts and Terminology
- Be familiar with stress-shortening cycles, force velocity relationships, and planning rep schemes based on training ages.
- Anticipate discussions on various drill classifications and their applications in programming for athletes.
- Expect to calculate load volume and understand the general adaptation syndrome, which outlines the body’s response to stressors.
