Eccentric Training in Tulsa, OK
Supramaximal eccentric overload training for athletes, coaches, trainers, and fitness enthusiasts across the Tulsa metropolitan area.
Oil Country Has Always Had a Specific Kind of Physical Toughness
Tulsa's identity is shaped by the energy industry and by a physical culture that comes with it. The oilfield services and manufacturing workforce here has a work ethic and physical seriousness that runs through the athletic culture of the city. The University of Tulsa competes at the American Athletic Conference level across football, basketball, and soccer. The Drillers minor league baseball affiliate competes professionally. And Tulsa's recreational running and cycling communities train seriously year-round.
For TU athletes and Tulsa's football and field sport community, the eccentric demands of their sports are specific. Research documents that during rapid deceleration events, peak muscle activation can reach 161 percent of maximal voluntary isometric contraction. For TU Golden Hurricane football skill players and basketball guards stopping at the perimeter, those demands determine performance across a full AAC season.
For Tulsa's endurance running community, research documents eccentric exercise programs are well-supported in the literature for addressing the neuromuscular demands that most frequently interrupt consistent training. The eccentric loading research in these areas is peer-reviewed and substantial. CCR Specialist course graduates working with Tulsa's running community are trained to apply these protocols within their scope of practice. The eccentric phase generates 1.3 to 1.75 times the concentric force. The Eccentric Training Video Series explains the full science.

Tulsa's Athletic Landscape
The University of Tulsa competes in the American Athletic Conference and consistently produces NFL draft picks from its football program. The Roughnecks XFL team brings professional football to the city. The Drillers Double-A affiliate plays professional baseball. The BOK Center hosts concerts and events that bring national attention to the city. And the physical culture of the oil and gas workforce, which values practical strength and durability, creates a training market that evaluates tools on what they actually deliver.
For Tulsa's sprint and field sport athletes, hamstring strains are the most prevalent soft tissue injury in sprinting sports, with recurrence rates reaching 31 percent. Strength and conditioning professionals working across Tulsa's athletic community who complete the CCR Specialist course are trained to apply calibrated eccentric overload methodology to address that root neuromuscular mechanism specifically.
Our Custom Calibrated Resistance system has been trusted by athletes across the MLB, NFL, NBA, ATP, WTA, LIV Golf, and Olympic programs. Tulsa coaches and athletes who want access to that same technology now have it.


A Session
Connect the Force Board dynamometer, select your exercise, and begin. The device tracks force output from the first rep. The Synapse CCR continuously and precisely calibrates the resistance to match your strength throughout the full range of motion, training the concentric, isometric, and eccentric phases of movement to their maximum potential. A feat that simply cannot be accomplished with conventional equipment.
One set lasts approximately 90 seconds and exhausts all muscle fiber types.

The Mechanism
The Synapse CCR uses a patented pulley mechanism to continuously calibrate resistance to actual force potential throughout the full range of motion. Both phases trained to their true maximum. Conventional equipment cannot go beyond the concentric ceiling.
The efficiency that results is documented in the research: high mechanical loads at substantially lower metabolic cost than concentric exercise.

The Comparison
Every training tool that builds strength deserves respect. The Synapse CCR provides one specific capability that does not exist in conventional tools: independent calibration of the eccentric phase to actual eccentric capacity.
-
Weights cap at the concentric maximum. The eccentric phase receives that same load, far below actual capacity.
-
Bands drop through the eccentric return, under-loading the most productive phase.
-
Flywheel devices tie eccentric load to concentric effort rather than calibrating it independently.
For Tulsa's practically-minded training community, which values what actually works over methodology marketing, the Synapse CCR's independent eccentric calibration is the distinction that produces genuinely different outcomes.
The Inventor
Raj Chaudhuri spent over two decades coaching professional tennis at the highest level, including WTA champions, Grand Slam players, and Olympic and Fed Cup teams. He could not deliver eccentric overload to his athletes with anything that existed. He built a patented solution using the physics of mechanical advantage. The science led the engineering.

The Design
The Synapse design addresses the failure of conventional equipment: fixed loads cannot respond to the athlete's eccentric capacity at each point in the movement. Custom Calibrated Resistance responds at every instant.
For Tulsa coaches and trainers working across the TU athletic pipeline, the oil industry workforce, and the endurance community, the device's adaptability makes it practical across all three.
Who the Synapse Is For in Tulsa
The device scales from beginner fitness populations through elite competitive preparation. Anyone from 9 to 90 can use it.
In Tulsa specifically:
-
TU Golden Hurricane athletes and coaches — AAC football, basketball, soccer, and program athletes who need training beyond conventional equipment
-
Energy sector and industrial workforce — Tulsa's oil and gas and manufacturing workforce whose occupational demands benefit from eccentric strength building
-
Endurance runners and cyclists — Tulsa's serious running community where eccentric loading demands are significant and the research literature is well-established

The Research
The scientific foundation behind eccentric overload is substantial. Twenty-six published studies are cited on the Synapse CCR website. Hedayatpour and Falla's 2015 review in BioMed Research International documents that eccentric loading produces muscle hypertrophy, increased cortical activity, and motor unit behavior changes that contribute to improved muscle function. Hoppeler's 2016 review in Frontiers in Physiology establishes that eccentric exercise achieves high mechanical loads at substantially lower metabolic cost than concentric exercise.
