Interdependence of Performance-Related Fitness Components: Strength, Power, Speed & More

In sports and fitness, high-level performance is never built on a single physical quality. Instead, it’s the interdependence of performance-related fitness components—like strength, power, speed, agility, flexibility, and endurance—that creates an athlete’s edge.

As emphasized in Bompa & Carrera’s sports conditioning model and supported by peer-reviewed scientific studies, optimizing one component often enhances several others. This article provides an expert overview of how these components relate and how to train them effectively.


What Are Performance-Related Fitness Components?

These are physical traits essential for sport-specific performance. Unlike health-related components (e.g., body composition, basic cardiovascular health), performance-related traits are responsible for:

  • Explosive movement
  • Sustained force output
  • Quick directional changes
  • Long-duration work capacity

They must be trained together, not in isolation.


1. Strength: The Foundation of All Physical Qualities

Definition: The ability to generate force against resistance (Force × Distance).
Why it matters: Strength is the foundation for developing power, speed, and injury prevention.

“Strength is the adaptation that leads to all other adaptations that you really care about.” – Charles Staley

Training types:

  • Isometric (static): Planks, gymnastic holds
  • Dynamic: Squats, deadlifts, bench press
  • Power-dominant: Olympic lifts

Evidence: Strength training reduces injury risk in young athletes (Faigenbaum & Schram, 2004).


2. Power: The Bridge Between Strength and Speed

Definition: Power = Force × Distance ÷ Time
Key trait: Combines strength with speed of execution.

Application examples:

  • Olympic lifts
  • Sprinting
  • Jumping
  • Throwing

Research Insight: Increased power is more related to force development than movement speed alone (Bompa, 2015).


3. Speed: Maximal Movement Velocity

sprint

Definition: Speed = Distance ÷ Time
Subcomponents:

  • Reaction time (responding to stimuli)
  • Movement time (completing a motion)
  • Sprint speed (stride length × stride frequency)

Training Dependency: Strong, powerful muscles enhance acceleration and top-end speed.

Note: Speed is limited without strength and refined with coordination.


4. Agility: Quick, Controlled Directional Changes

Zig Zag Hops Plyometric

Definition: The ability to decelerate and change direction efficiently.

Relies on:

  • Strength and power for forceful deceleration/re-acceleration
  • Motor control for coordination and body awareness

Training Tip: Avoid repeating the same drill all year. Agility training must include sport-specific variation to prevent plateaus.


5. Endurance: Sustained Output Over Time

Aerobic Endurance

  • Long, submaximal efforts (>3 minutes)
  • Example: Distance running, long sets

Anaerobic Endurance

  • Short, intense bursts (<60 seconds)
  • Example: Sprints, interval training

Muscular Endurance Types:

TypeExample
Continuous tensionPlanks, climbing
IsometricStatic holds, isometrics
Repetitive dynamicRowing, high-rep training
Short rest/high effortCircuit training, football

These types exist on a continuum and frequently overlap depending on sport demands.


6. Flexibility: Controlled Range of Motion

Dynamic Flexibility:

  • Performed before training
  • Enhances joint mobility without power loss

Static Flexibility:

  • Best after training
  • Used for areas with specific tightness (based on screening)

Scientific Caveat:
Pre-exercise static stretching may reduce strength and power for up to an hour (Evetovich et al., 2003; Young & Behm, 2003).

Context-Specific Use:

  • Gymnasts and martial artists require high ROM
  • Excessive flexibility may hinder performance in power sports (Jones, 2002)

7. Coordination and Motor Skill Development

Turkish Get-up

Coordination includes:

  • Timing
  • Rhythm
  • Spatial awareness
  • Movement sequencing

Coordination is what connects raw physical power to functional athleticism. All athletes benefit from integrating drills that enhance neuromuscular timing and control.


The Training Principles You Need to Know

1. Specificity: Train according to your sport or goal.
2. Overload: Progressively increase intensity or volume.
3. Variation: Rotate stimulus to avoid plateau.
4. Recovery: Respect residual training effects—each fitness quality decays at a different rate.

AdaptationHow Long It Lasts (Average)
Strength30+ days
Endurance15–30 days
Speed5–10 days

Conclusion: Why It All Works Together

Performance-related fitness components don’t operate in silos. Your ability to sprint, jump, change direction, or recover from fatigue is determined by how well your entire physical system works together.

Whether you’re a coach, athlete, or recreational trainee, building programs that address strength, power, speed, endurance, flexibility, and coordination in a cohesive, progressive way is the path to performance.
