Written by Gabe Derman | August 10, 2024
Want to help your athletes jump higher and sprint faster? You can unlock their potential for explosive movement with plyometrics training.
 
In this episode of the Keiser Education Series (KES), renowned strength and conditioning experts Dan Ridenour, Assistant of Player Performance and Sports Science Coordinator for the Minnesota Vikings, and Dr. Ramsey Nijem, Director of Performance, University of Kansas Men's Basketball, explore the fundamentals of plyometrics. Drawing from their wealth of experience, they'll provide programming considerations and practical tips for coaches of all levels.
 

Understanding Plyometrics: The Science Behind Explosive Movement

Plyometrics centers around the principle of the stretch-shortening cycle (SSC). The SSC is a rapid muscle lengthening (eccentric phase) followed immediately by a shortening (concentric phase). This quick transition, like stretching a rubber band and releasing it, generates powerful, explosive movements.
 
Some of the benefits of plyometric training include:
  • Increased Rate of Force Development: Enhances the ability to generate force quickly, crucial for explosive movements like jumps and sprints.
  • Neuromuscular Coordination: Improves the synchronization between the nervous system and muscles, leading to more precise and efficient movement patterns.
  • Increased Strength: Builds muscular strength by engaging and challenging fast-twitch muscle fibers through explosive exercises.
  • Increase in Performance-Related Movements: Enhances skills in activities like jumping, sprinting, throwing, and quick changes of direction, improving overall athletic performance.
 

Individualized Plyometric Programs for Peak Performance

Individualization is key for any training program. A basketball player’s plyometric program can differ significantly from a football lineman’s, reflecting the unique demands of their respective sports. Factors such as training age, injury history, and individual biomechanics further shape the ideal program.
 

Building a Plyometric Foundation: Essential Insights for Coaches

Creating a safe and effective plyometric program requires a structured approach. As a coach, it is critical to emphasize proper technique and utilize a gradual progression. Programming should account for the athlete's training age, physical abilities, preparedness and readiness. 
 

Classifying Plyometrics:

  • Key Factors: Amplitude (height/depth), distance, velocity, and plane of motion (sagittal, frontal, transverse) are key variables to manipulate.
  • Progression: Start with simple, low-impact exercises and gradually progress to more complex and demanding movements.
 

Prioritizing Eccentric Control:

  • Brakes Before Gas: Athletes must master the ability to absorb force (eccentrically) before they can effectively produce it (concentrically).
  • Snapdowns: Snapdowns are an excellent example of a safer, low-impact starting point for plyometrics. To execute these movements, athletes are asked to begin in a tall posture and rapidly transition into a more athletic landing position. Coach athletes to “slam on the brakes” upon landing, mimicking an “e-break” system.
 
The following video provides a guide on plyometric exercises designed to enhance an athlete's ability to absorb force eccentrically before progressing to concentric movements. It emphasizes the importance of building a strong foundation in force absorption to help prevent injuries and maximize power output.
 

 

Key points from the video:
  • Fundamental Plyometric Exercises: The video covers essential exercises like pogos, snapdowns, and depth drops (both double and single leg) that help athletes develop the necessary skills to absorb force efficiently.
  • Advanced Movements: It progresses to more advanced exercises such as single leg hops and fast-paced movements with reactive and hard decelerations.
  • Technique Focus: The video emphasizes maintaining proper form, such as keeping knees over toes and shoulders over knees, and actively pulling oneself down to achieve a stable landing position.

Sagittal, Frontal, and Transverse Plane Progression:

  • Mastering the Basics: Begin with sagittal plane movements (forward and backward) before progressing to frontal (side-to-side) and transverse (rotational) planes.
  • Progressive Overload: Gradually increase the complexity within each plane. For example, progress from bilateral snapdowns to unilateral snapdowns
While this video doesn't cover all three planes extensively, it provides a solid framework for understanding plyometric progressions. You can use this as a starting point and supplement with information about sagittal and transverse plane exercises. 
 
 
 

Control Before Chaos:

  • Technical Proficiency: Emphasize proper landing mechanics, core stability, and controlled movements, especially early in the training process.
  • Introducing Unpredictability: As athletes develop competency, gradually introduce elements of chaos and unpredictability to mimic game situations.

The following video covers the essential aspects of mastering control before progressing to more chaotic and unpredictable exercises. 

 
 
Key points from the video: 
  1. Technical Proficiency:
    • Proper Landing Mechanics: The video emphasizes the importance of proper landing mechanics, ensuring athletes land softly with knees tracking over toes and avoiding valgus knee collapse. This foundational skill is crucial for preventing injuries and building a strong base for more advanced movements.
    • Core Stability: Exercises like snapdowns and drop freezes are highlighted, which focus on teaching athletes to absorb force through triple flexion and maintain core stability. These exercises are fundamental to developing the control needed for more complex plyometric drills.
  2. Introducing Unpredictability:
    • Progression to Chaos: Once athletes have mastered the basics, the video introduces more advanced plyometric exercises that incorporate elements of unpredictability, such as depth jumps and single-leg variations. These exercises mimic game situations where athletes must react to unexpected stimuli and maintain control under dynamic conditions.

Effective Cueing Techniques:

  • Internal and External Cues: Utilize both types of cues to enhance learning.
    • Internal Cue Example: "Land with your hips back, full foot, and engage the core."
    • External Cue Example: "Pretend the floor is lava on each consecutive jump."
  • Clear and Concise Communication: Use language that athletes understand and provide specific, actionable feedback.

 

Athlete Education and Buy-In:

  • The “Why” Behind Training: Explain the rationale behind training decisions to athletes. This fosters understanding, trust, and motivation.
  • Open Communication: Encourage athletes to ask questions and provide feedback on their training experience. As athletes mature physically and with training age, empowering them to be a part of the decision-making process can help increase buy-in.

Plyometrics and Technology: Tools to Optimize Performance

Technology can provide valuable insights to inform plyometric training. However, as a coach, you shouldn't rely on it exclusively.
 

Force Plate Analysis:

  • Objective Measurement: Force plates quantify key metrics like reactive strength index (RSI), peak power, time to stabilization, and eccentric utilization ratio (EUR). This data can help you assess asymmetries, monitor progress, and guide programming decisions.
  • Data-Driven Insights: For example, a low RSI might indicate a need for increased stiffness and reactivity, while a high asymmetry score could highlight a potential injury risk.

Accessible Alternatives for Coaches:

  • Budget-Friendly Options: Jump mats, Vertec units, and smartphone apps like MyJump 2 offer affordable alternatives for tracking jump height, contact time, and other relevant metrics.
  • Practical Application: Use these tools to set training goals, monitor progress, and keep athletes engaged.

The Power of Video Analysis:

  • Visual Feedback: Video analysis provides immediate visual feedback, allowing athletes to see and understand their movement patterns.
  • Practical Tips: Film from various angles (side, front, rear) and use slow-motion playback to analyze technique in detail.

Integrating Plyometrics with Strength Training: A Holistic Approach

You should integrate plyometrics with strength training and other modalities to create a well-rounded program for your athletes.
 

The Importance of a Well-Rounded Program:

  • Synergy of Training: Strength training builds the foundational strength necessary for effective plyometric execution. Plyometrics enhance the rate at which athletes can express this strength.

Periodization Strategies:

  • Off-Season vs. In-Season: During the off-season, prioritize building a base of strength and power. As the season approaches, shift the focus to maintaining these qualities while minimizing fatigue.
  • Training Cycles: Integrate plyometrics strategically within micro, meso, and macro cycles, aligning with the overall training goals and the athlete’s recovery needs.

Vertical Integration and Complex Training:

  • Vertical Integration: Different training elements complement and enhance each other. For example, heavy strength training might precede a plyometric session, capitalizing on the potentiation effect.
  • Complex Training: Pairing a strength exercise with a biomechanically similar plyometric exercise can enhance both strength and power. A classic example is pairing squats with jumps.

Plyometrics In-Season: Maintaining Power When it Matters Most

In-season plyometrics require a delicate balance between maintaining explosiveness and managing fatigue.

 

A Cautious Approach:

  • Reduced Volume and Intensity: Significantly reduce the volume and intensity of plyometric drills compared to the off-season to avoid overtaxing athletes. A general guideline is to aim for 10-25 jumps per session, adjusting based on individual needs and recovery.
  • Exercise Selection: Prioritize exercises that closely mimic game-day demands and focus on maintaining, rather than maximizing, power output.

Monitoring Athletes:

  • Communication is Key: Maintain open communication with athletes, asking about their recovery, soreness, and overall well-being.
  • Objective Monitoring: Track jump height, contact time, and other relevant metrics to monitor for signs of fatigue or overtraining.

Maintaining, Not Gaining:

  • Shift in Focus: The primary goal during the season is to maintain the power and explosiveness developed in the off-season, not necessarily to make significant gains.
  • Strategic Implementation: Use plyometrics strategically, perhaps once or twice a week, to reinforce proper movement patterns and maintain explosiveness.

Return to Play and Plyometrics: A Gradual and Strategic Comeback

Reintroducing plyometrics after an injury necessitates a cautious and individualized approach.

 

Collaboration with Medical Professionals:

  • Teamwork: Work closely with athletic trainers, physical therapists, and other medical professionals to develop a safe and effective return-to-play plan.

Gradual Progression and Monitoring:

  • Step-by-Step: Start with basic, low-impact exercises and gradually progress to more demanding movements as the athlete tolerates.
  • Careful Observation: Monitor for any signs of pain, discomfort, or altered movement patterns. Adjust the program as needed.

Individualized Plans:

  • Unique Needs: Each athlete’s return-to-play plan should be tailored to their specific injury, medical history, and individual needs.
  • Communication and Collaboration: Maintain open communication with the athlete throughout the process, addressing their concerns and adjusting the plan as needed.
