From the Summit of Strength 2026 in Cesena: New Scientific Evidence Explained by Prof. Antonio Paoli
On February 1, 2026, the Summit of Strength took place in Cesena. The event was organized by StrongFirst and sponsored by SIDEA, the European benchmark for professional equipment dedicated to strength training, functional training, and athletic preparation.
Among the most highly anticipated speakers at the convention, Prof. Antonio Paoli—professor at the University of Padua and director of the Nutrition and Exercise Physiology Laboratory—addressed one of the most debated topics in the world of training:
“Hypertrophy and Strength: A Linear Relationship?”
A question of interest to:
- personal trainers
- strength coaches
- powerlifters
- athletic trainers
- bodybuilding enthusiasts
- functional training and hybrid training practitioners
- athletes wishing to increase strength and muscle mass effectively.
For years, the concept of “more muscle = more strength” was taken almost for granted.
But sports science today reveals a much more complex and interesting reality.
Muscle Strength and Hypertrophy: The Relationship Exists, but It Is Not Automatic
One of the key concepts that emerged during the Summit of Strength 2026 is that:
muscle growth contributes to strength potential, but it does not automatically guarantee a proportional increase in performance.
In other words:
- you can increase muscle mass without becoming much stronger;
- you can become much stronger even without massive increases in muscle volume.
According to Paoli, strength is a multi-factorial capacity influenced by:
- the nervous system;
- muscle quality;
- biomechanics;
- execution technique;
- muscle architecture;
- intermuscular coordination;
- nutrition and recovery.
This explains why we often observe an apparently paradoxical phenomenon in the gym:
Why do some “smaller” athletes lift more weight than highly muscular individuals?
Prof. Paoli defined this scenario as the “Gym Paradox.”
Anyone who practices:
- powerlifting,
- weightlifting,
- streetlifting,
- strength training,
- functional fitness,
has seen this dozens of times.
Two people approach the same exercise — squat, bench press, or deadlift — but one manages to move the load with apparent ease while the other struggles enormously, despite having more muscle mass.
This is because:
Strength does not depend solely on muscle size
Muscle mass represents the “engine,” but the final result also depends on:
- neurological efficiency;
- fiber recruitment;
- activation speed;
- technique;
- biomechanical levers;
- coordination skills coordination; levers;
- coordination skills.
Muscle Quality: The True Meaning of a “Strong Muscle”
During the conference, Paoli explored the concept of muscle quality—specifically, a muscle’s ability to produce force relative to its size.
Two people can have:
- the same muscle volume;
- the same circumference;
- the same lean mass;
yet express completely different levels of strength.
What determines muscle quality?
Several factors come into play:
Muscle Fiber Type
Fast-twitch fibers (Type IIx) produce more force and power compared to slow-twitch fibers.
Neural Efficiency
The nervous system determines:
- how many fibers are activated;
- how quickly they activate;
- how effectively they work together.
Molecular Properties
The behavior of contractile proteins and the actin-myosin cycle also directly influence force production.
Muscle Architecture: How the muscle is built also matters
One of the most fascinating aspects discussed during the presentation was skeletal muscle architecture.
It is not enough to simply have “more muscle”:
the way the fibers are organized is highly critical.
Pennation Angle
The pennation angle refers to the inclination of muscle fibers relative to the tendon.
An increased pennation angle allows for:
- packing more fibers into the same volume;
- increasing the muscle’s physiological cross-sectional area;
- boosting strength potential.
However, beyond certain biomechanical limits, efficiency decreases.
Fascicle Length
Muscles with longer fascicles tend to favor:
- speed;
- explosiveness;
- range of motion.
In contrast, more “compact” muscles are often better suited for maximal force production.
Strength Training: The Fundamental Role of the Nervous System
One of the most important messages from the Summit of Strength was that:
Strength is also a neurological skill
In the early stages of strength training, performance gains often occur even before any actual muscle hypertrophy is observed.
This happens because the nervous system rapidly improves its ability to:
- recruit motor units;
- activate high-threshold fibers;
- increase firing frequency;
- synchronize muscle groups;
- reduce neural inhibition.
In practice, the body becomes more efficient at utilizing the muscle that is already present.
What is the Rate of Force Development (RFD)?
Among the more technical yet highly useful topics for understanding real-world performance, Paoli spoke about the Rate of Force Development (RFD).
RFD represents:
the ability to develop force in the shortest time possible.
This parameter is essential in:
- sprinting;
- jumping;
- changes of direction;
- combat sports;
- weightlifting;
- athletic preparation;
- functional training.
According to the evidence presented during the congress, the ability to express force rapidly is often more relevant than mere absolute maximal strength.
Muscle Hypertrophy: Still fundamental, but needs context
The presentation certainly did not downplay the importance of hypertrophy.
Increasing muscle mass means increasing the potential for force production.
However:
There is no perfectly linear relationship between hypertrophy and strength
The studies presented show a high degree of individual variability:
- some people achieve massive strength gains with very little hypertrophy;
- others experience a significant increase in muscle volume but show relatively little performance improvement.
This explains why seemingly identical programs can produce completely different results.
Nutrition and Strength: How Much Does Diet Really Matter?
Another central topic addressed by Prof. Paoli concerns the role of nutrition in strength performance.
Studies were presented on:
- Time-Restricted Eating (TRE);
- intermittent fasting;
- the ketogenic diet;
- energy metabolism;
- inflammation;
- recovery;
- the balance between protein synthesis and degradation.
The evidence shows how certain nutritional strategies can:
- improve body composition;
- reduce fat mass;
- influence hormonal balance;
- modulate fatigue and inflammation;
without necessarily compromising maximal strength.
What does all of this mean for those who train?
The conclusions of Prof. Antonio Paoli’s presentation at the Summit of Strength 2026 are extremely practical.
If the goal is maximal strength:
you need to work on:
- technique;
- coordination;
- neural efficiency;
- motor recruitment;
- movement quality;
- multi-joint exercises;
- strength-specific training.
If the goal is hypertrophy:
the central elements become:
- training volume;
- mechanical tension;
- recovery;
- nutrition;
- load progression;
- fatigue management.
SIDEA and the culture of physical preparation
The Summit of Strength 2026 represented much more than a simple educational event.
It was a moment of confrontation and synergy between:
- sports science;
- strength training;
- biomechanics;
- sports nutrition;
- athletic preparation.
SIDEA has always promoted a vision of training based on:
- movement quality;
- research;
- technical updates;
- performance development;
- professional equipment for strength and conditioning.
For this reason, supporting high-profile scientific events like the Summit of Strength perfectly reflects SIDEA’s philosophy:
Train better to truly become stronger.
Conclusions: Being bigger does not automatically mean being stronger
The final message emerging from Prof. Antonio Paoli’s presentation is clear:
Strength cannot be reduced to muscle size alone.
Performance is born from the interaction between:
- the nervous system;
- muscle architecture;
- biomechanics;
- technique;
- nutrition;
- muscle quality;
- training experience.
And it is precisely this complexity that makes the world of strength training so fascinating.
For coaches, athletes, and enthusiasts, the real goal should not just be “getting bigger,” but:
building a body capable of expressing strength in an efficient, coordinated, and functional way.
