Eccentric Training Certification | Custom Calibrated Resistance Specialist
The Official Synapse CCR Certification Program for coaches, trainers, and physical therapists.
What This Certification Is
The Custom Calibrated Resistance Specialist 1.0 is the official two-day certification course for the Synapse CCR system. It is designed for coaches, personal trainers, strength and conditioning professionals, and physical therapists who want to understand and apply supramaximal eccentric and isokinetic training with their clients.
The course covers the science, the device, and the application. You leave with the knowledge to program eccentric overload training across populations from elite athletes to post-operative rehabilitation patients, and the credentials to demonstrate that competency to clients and employers.
Synapse CCR is an Approved Provider for continuing education. The Custom Calibrated Resistance Specialist 1.0 course awards NASM 0.8 CEU and AAFA 0.8 CEU upon successful completion.
What You Learn
The course is structured across two days combining classroom science instruction with hands-on lab application.
-
The science of Custom Calibrated Resistance. How CCR eliminates the constraints of conventional training methods by precisely calibrating to the user's force at all times. Why this produces a training stimulus that conventional equipment cannot replicate.
-
Supramaximal Eccentric Training. The physiology of the eccentric phase, why it generates significantly greater force than the concentric phase, and how eccentric overload produces adaptations that conventional training cannot access.
-
Maximal Isokinetic Training. The science and application of isokinetic loading, which the Synapse CCR enables across the full range of motion in a way no conventional tool can deliver.
-
Lab application. Hands-on movements that engage entire kinetic chains and demand increased neural drive. You will apply these concepts to real training scenarios under direct instruction.
-
Population-specific programming. Applications across all demographics, from elite athletes preparing for competition to post-operative patients working through rehabilitation progressions.
-
Device operation and programming. How to set up the Synapse CCR, operate the Force Board dynamometer, interpret real-time force data, and build sessions for different client goals.
Who This Is For
The certification is designed for professionals who work directly with athletes, clients, or patients in a training or rehabilitation context.
-
Personal trainers and private coaches who want to offer clients a training stimulus that genuinely exceeds what conventional gym equipment can provide.
-
Strength and conditioning coaches working with teams or individual athletes who need measurable, calibrated eccentric overload in their programming.
-
Physical therapists and sports medicine professionals whose clinical work involves eccentric loading protocols for tendinopathy treatment, ACL rehabilitation, and return-to-sport progressions.
-
Athletic trainers working at the collegiate or professional level who want to add the Synapse CCR to their athlete development toolkit.
-
Coaches and trainers in any sport or fitness context where performance, durability, and efficient training stimulus matter.
