Why Strength Is King: The Mother Quality Behind Speed, Power, and Longevity

Strength training is often presented as one of many tools in a coach’s toolbox. In reality, it is the tool that shapes almost everything else.

Modern sport science has repeatedly demonstrated that improvements in strength influence speed, power, movement efficiency, and even longevity. German sports scientist Dietmar Schmidtbleicher captured this perfectly when he said, “Strength is the mother of all qualities.”

This article breaks down why that statement holds true, what the underlying physiology tells us, and how coaches can apply these principles to build better programs.

Why Strength Is Foundational

Strength, at its simplest, is the ability to produce force. Whether an athlete is sprinting, jumping, pressing, carrying, or resisting load, force production is the common denominator.

From a physiological standpoint, improvements in strength influence three major systems:

Motor Unit Recruitment

High-threshold motor units, the fibers responsible for explosive and high-force actions, are only accessed when the nervous system is exposed to heavy loads. These motor units are mostly dormant in beginners. Strength training teaches the body to access them.

Rate Coding and Synchronization

Once motor units are recruited, the nervous system has to fire them faster and in a more coordinated manner. Heavy strength training increases firing frequency, improves the sequencing of contractions, and reduces “noise” in the movement pattern.

Tendon Stiffness and Force Transmission

Tendons adapt to load by increasing stiffness and cross-link density. Stiffer tendons transmit force more effectively, improve efficiency in explosive tasks, and reduce injury risk.

Together, these adaptations form the base from which every other physical quality develops. Without strength, the athlete is operating on a weak chassis.

How Strength Drives Power and Speed

Power is a product of force and velocity:

Power = Force × Velocity

Coaches often chase the “velocity” side of that equation with jumps, plyometrics, and sprints. But for the majority of athletes, especially novices and intermediates, force is the limiting factor.

Stronger Athletes Produce More Force in Less Time

The ability to produce high levels of force rapidly (rate of force development, or RFD) is directly influenced by maximal strength. A higher force ceiling gives the athlete more usable power at every submaximal point on the curve.

For example:

• A stronger athlete needs a smaller percentage of max strength to produce the same absolute output.

• This allows for higher-quality, lower-fatigue power training.

• It also reduces technical breakdown under speed.

Better Strength Improves Movement Mechanics

Research consistently shows that stronger individuals:

• Accelerate faster

• Jump higher

• Maintain technique under fatigue

• Have more stable joint positions during high-velocity actions

A weak athlete trying to sprint or jump is limited not by the drills themselves, but by the inability to apply force quickly enough to change the outcome. Strength raises the ceiling.

Strength Supports Hypertrophy

Hypertrophy requires mechanical tension, and mechanical tension is determined largely by the force a muscle can produce or resist. Stronger trainees can generate higher tensions, which creates a more robust environment for growth.

Stronger Athletes Create Higher Tension

This means:

• More effective reps

• Higher mechanical loading across fibers

• Greater long-term hypertrophy potential

This is why elite coaches consistently emphasize getting stronger in foundational patterns before chasing advanced bodybuilding tactics.

Strength Enhances Resilience and Longevity

Beyond performance, strength has a profound impact on joint health, aging, and long-term durability.

Stronger Tissues Are Harder to Injure

Heavy loading:

• Increases tendon stiffness

• Improves ligament integrity

• Reinforces joint stability through muscular co-contraction

• Enhances bone density

These adaptations directly correlate with lower injury rates across populations.

Strength Reduces Compensations

Weak clients don’t move poorly because they’re “unathletic.”
They move poorly because they lack the force capacity to execute efficient patterns.

Once strength improves:

• Joint loading becomes more symmetrical

• Posture and alignment under load become more consistent

• Fatigue affects movement less

Strength Slows the Aging Curve

The decline of strength and power is one of the strongest predictors of:

• Loss of independence

• Fall risk

• Mobility limitations

Strength training is the only intervention shown to reverse age-related declines in muscle mass, bone density and power output..

It is not optional; it is essential.

Where Strength Stops Helping (Diminishing Returns)

Strength is foundational, but it is not infinite in its usefulness.

Strength Is Not a Linear Predictor Forever

Early in training, strength improvements drive everything. But once a trainee has established:

• Solid relative strength

• Good intermuscular coordination

• Efficient movement patterns

The transfer to speed or power becomes less direct. Strength remains a base, but no longer the primary bottleneck.

This is why advanced athletes shift emphasis to increased Rate of Force Development through:

• Power development

• Speed work

Strength still matters, but the returns are smaller.

Practical Recommendations for Coaches

Prioritize Strength in Early Training Age

Novices respond rapidly to:

• Basic lifts

• Moderate to heavy loads (60-85 percent)

• Simple, linear progressions

Strength improvements in beginners drive progress across all other qualities.

Keep Primary Patterns Consistent

Change assistance work as needed, but keep the main lifts stable enough to track:

• Estimated 1RMs

• Rep maxes

• Volume load

Avoid the Novelty Trap

Novice clients do not need:

• Complex variation

• Novelty-for-novelty’s-sake

• Advanced methods

• High volumes of speed or plyometric work

They need strength, technique, and exposure.

Strength is not just another fitness quality, it is the foundation that shapes all others. As Dietmar Schmidtbleicher said, “Strength is the mother of all qualities.”

It drives force production, supports power and speed, expands hypertrophy potential, protects joints, improves movement efficiency, and slows the aging process. For coaches and early-stage trainees, no other quality delivers more return on investment.

Bias strength early. Use it to build capacity. Then specialize as the athlete progresses.
