Rate of Force Development: The Missing Link in Explosiveness
When athletes think about becoming more explosive, they often focus on getting stronger.
And while strength is certainly important, it is only part of the equation.
Many athletes spend months increasing their squat, deadlift, or bench press, yet see little improvement in their sprint speed, vertical jump, or change-of-direction ability.
Why?
Because explosive performance is not just about how much force you can produce.
It’s about how quickly you can produce it.
This quality is known as Rate of Force Development (RFD), and it may be one of the most important—and most overlooked—components of athletic performance.
What Is Rate of Force Development?
Rate of Force Development refers to the speed at which an athlete can generate force.
In simple terms:
Strength = How much force you can produce
RFD = How fast you can produce that force
Imagine two athletes who can both produce 1,000 pounds of force.
If Athlete A reaches that force in 0.15 seconds and Athlete B reaches it in 0.40 seconds, Athlete A will almost always be more explosive.
The reason is simple:
Sport happens fast.
Most athletic movements occur in fractions of a second.
Athletes rarely have enough time to express their maximum strength.
Instead, they must generate force rapidly.
Why RFD Matters in Sport
Virtually every explosive athletic movement relies on rapid force production.
This includes:
- Sprinting
- Jumping
- Cutting
- Accelerating
- Decelerating
- Throwing
- Hitting
- Tackling
The athlete who can create force faster generally has a performance advantage.
Sprinting
During sprinting, athletes have only milliseconds to apply force into the ground.
The fastest athletes aren’t necessarily the strongest.
They’re often the athletes who can apply large amounts of force in the shortest amount of time.
This is one reason elite sprinters demonstrate exceptional power and explosiveness despite varying body types.
Jumping
Vertical jump performance depends heavily on RFD.
Athletes who rapidly generate force can:
- Leave the ground faster
- Reach greater heights
- Produce more explosive takeoffs
Two athletes may have identical squat strength, yet the athlete with superior RFD often jumps higher.
Change of Direction
Athletes must rapidly:
- Absorb force
- Control force
- Reproduce force
This is especially important in sports like:
- Soccer
- Football
- Basketball
- Lacrosse
- Volleyball
The ability to quickly transition from braking to propulsion is a major separator among elite athletes.
Strength Is the Foundation
Before athletes can develop high levels of RFD, they need sufficient strength.
Think of strength as the size of the engine.
RFD is how quickly that engine can accelerate.
A larger engine creates more potential force.
But if an athlete cannot access that force quickly, performance may still be limited.
This is why effective performance programs typically progress from:
- Strength Development
- Power Development
- High-Speed Force Production
Each phase builds upon the previous one.
How We Train Rate of Force Development
Improving RFD requires specific training methods.
Simply lifting heavier weights is not enough.
Athletes must learn to produce force rapidly.
Plyometrics
Plyometric exercises are among the most effective tools for developing RFD.
Examples include:
- Vertical jumps
- Broad jumps
- Bounds
- Hops
- Drop jumps
These movements train the nervous system to generate force quickly while improving the efficiency of the stretch-shortening cycle.
Olympic Lift Variations
Exercises such as:
- Hang cleans
- Power cleans
- High pulls
Require athletes to generate force rapidly through triple extension.
These movements are excellent for bridging the gap between strength and explosive performance.
Velocity-Based Training
At SPECTRUM, we utilize Velocity-Based Training (VBT) through OVR Performance.
VBT measures bar speed during lifts and helps ensure athletes are training for the desired adaptation.
Instead of simply moving heavy weights, athletes learn to move loads with intent and velocity.
This creates a direct transfer to explosive athletic performance.
Sprint Training
Sprint training itself is one of the most specific methods of developing RFD.
Acceleration training teaches athletes to:
- Apply force rapidly
- Improve ground contact efficiency
- Generate explosive propulsion
Simply put, if you want to become faster, you must train speed.
French Contrast Training
French Contrast Training combines:
- Heavy strength work
- Plyometrics
- Speed-strength exercises
- Assisted explosive movements
This method targets multiple aspects of force production simultaneously and is one of our favorite approaches for developing power and RFD in advanced athletes.

The Nervous System Connection
One of the reasons RFD is so important is because it is heavily influenced by the nervous system.
Explosive athletes aren’t just stronger.
Their nervous systems are more efficient at:
- Recruiting muscle fibers
- Coordinating movement
- Producing force rapidly
This is why explosive training requires:
- High quality
- Full recovery
- Maximum intent
Fatigued athletes cannot produce force at high rates.
Quality matters more than quantity.
Measuring Explosiveness
Today, technology allows us to objectively evaluate explosive qualities.
At SPECTRUM, we utilize tools such as:
- VALD ForceDecks
- Just Jump
- OVR Velocity-Based Training
- Brower Timing Systems
These systems help us assess:
- Jump performance
- Reactive Strength Index (RSI)
- Power output
- Sprint speed
- Force production characteristics
By measuring performance, we can better individualize training and monitor progress.

Common Mistakes Athletes Make
Only Focusing on Strength
Strength is important, but strength alone does not guarantee explosiveness.
Ignoring Speed Training
Athletes cannot become explosive without moving explosively.
Excessive Conditioning
Too much conditioning can reduce power output and compromise explosive adaptations.
Training Without Intent
Explosive training requires maximal effort and intent on every repetition.
Moving slowly produces slow adaptations.
Final Thoughts
Strength matters.
Power matters.
But the ability to express force quickly may be the true difference-maker in athletic performance.
Rate of Force Development is the bridge between strength and explosiveness.
It’s what allows athletes to:
- Accelerate faster
- Jump higher
- Change direction more effectively
- Perform at a higher level in competition
The strongest athlete is not always the most explosive.
The athlete who can generate force the fastest often is.
That’s why at SPECTRUM, we don’t just train athletes to be stronger.
We train them to be explosive.
