The Nervous System Behind the Athlete

Built for Performance

A complete system for the care of the athlete, from the nervous system that produces the edge to the rehabilitation that restores it. Sixty-four lessons on how performance is built, protected, and brought back, written for the athletes who can choose anyone and the people who vet their care.

This section is organized in five parts: the athlete's nervous system, assessment and movement, injury and return, recovery and fueling, and the whole athlete and the team. The sixty-four lessons sit inside those five parts, from the foundation up.

Part One · 8 lessons

The Athlete's Nervous System

The athletic edge is neurological before it is muscular. Clinical reaction time across 2,584 collegiate athletes averaged 202 milliseconds, and the vestibulo-ocular reflex begins correcting the eyes 8.6 milliseconds after the head moves. The cerebellar cortex unfolds to 78 percent of the surface of the neocortex. A single session of spinal manipulation raised maximum motor evoked potential in a hand muscle by 54.5 percent, with a spread wider than the average. Eight lessons on proprioception, cerebellar timing, sport vision, and autonomic control.

Assessment and Movement

Eighty five percent of athletes pass a pre-participation exam, and 58 percent of the denials rest on the history alone rather than on the hands. Imaging is the blunter tool, and findings turn up often enough in athletes without symptoms that a picture rarely settles a question by itself. Mechanics carry the rest: about 86 percent of the energy crossing a thrower's elbow arrives from the motion of the trunk. Fourteen lessons on screening and on how force is produced.

Assessment and the Pre-Participation ExamReading the Athlete

Before performance is built it is measured. The examination that maps an athlete's structure, movement, and nervous system, and decides what is ready and what is not.

Movement and MechanicsProducing Force

How force is generated and transferred through the body. Gait, the kinetic chain, and the spine as the axis every powerful movement is organized around.

Injury, Rehab and Return

Every athlete gets hurt, and the pattern is readable. Ankle ligament sprains are the most common injury in collegiate sport at 15 percent of the total. Noncontact mechanisms account for 55 percent of anterior cruciate ligament tears, and 9 percent of concussions involve loss of consciousness. Return to play is a decision about a nervous system: six months after reconstruction, 57 percent of athletes cleared a 90 percent symmetry index but only 29 percent matched their own preinjury capacity. Sixteen lessons from mechanism to comeback.

Injury by RegionThe Body, Mapped

Region by region, how the athletic body is hurt and how it is read. From concussion to the ankle, the mechanism, the assessment, and the path back.

Rehab, Prevention and Return to PlayThe Comeback

Rehabilitation is a science with stages, criteria, and a finish line. How tissue is rebuilt, load is managed, and an athlete is cleared to compete again.

Part Four · 12 lessons

Recovery and Fueling

Training is the stimulus and recovery is where the adaptation happens. Guidance holds fluid loss under 2 percent of body mass, though the measured performance cost at that level is smaller than the rule implies. Muscle protein synthesis rises 76 percent in the day after a hard bout, and satellite cells are still climbing at day 8. Heart rate variability is the instrument that reads the recovery underneath all of it. Twelve lessons on recovery, sleep, and fuel.

Recovery and ResilienceBetween Efforts

Adaptation happens in recovery, not in the session. Heart rate variability, vagal tone, sleep, and the stress response that decide whether training builds or breaks an athlete.

Physiology and FuelingThe Engine

The energy systems that power sport and the fuel that feeds them. Physiology, nutrition, hydration, and the systemic conditions that quietly limit output.

The Whole Athlete and the Team

Athletes are not interchangeable. Women tear the anterior cruciate ligament at 1.7 times the male rate overall, and the gap runs from parity in alpine skiing to 5.5 in sports built on fixed-object landings. Peak VO2 falls 3 to 6 percent per decade in the twenties and above 20 percent per decade from the seventies, and training sets the height of that curve rather than its slope. The only peer-reviewed audit of chiropractic on National Football League medical staffs found 31 percent of teams. Fourteen lessons on the whole athlete, field care, and the standard the highest level expects.

The Whole AthleteEvery Athlete

Performance is personal. The female athlete, the youth and masters athlete, the para-athlete, and the mind, body, and environment each athlete competes within.

On the Field and at the Highest LevelThe Standard

What care looks like when it operates at the level of professional sport. Field emergencies, brain-based training, the performance team, and the standard elite athletes expect.

Questions Athletes Ask

Is chiropractic good for athletes?

Yes. Athletes ask more of their bodies than anyone, and chiropractic care is built around the system that coordinates every movement, the nervous system. An adjustment is an input to joint motion and to the mechanoreceptors that report it, and that afferent stream is what the brain uses to organize the next movement. This section states what is measured, what each measurement means, and where the model's own reading begins.

Can chiropractic care improve athletic performance?

Performance is a neurological event before it is a muscular one, and this practice works at that level rather than promising a result. Joint position sense in degrees, reaction time and its variability, and cortical drive are all measurable, and these lessons report what the trials found, including the trials that found nothing.

What is a chiropractic neurologist?

A chiropractic neurologist is a chiropractor with advanced board certification in functional neurology, a credential held by a small fraction of the profession. Dr. Jason Dulberg is a board-certified chiropractic neurologist (DACNB, FACFN), which means an athlete is assessed and cared for through the lens of the brain and nervous system, not the joints alone.

Do professional athletes use chiropractors?

Chiropractors work alongside athletic trainers, strength coaches and team physicians across professional and collegiate sport. The measured proportions are more modest than the figures that circulate: the only peer-reviewed audit of National Football League medical staffs found 31 percent of teams, and it is more than twenty years old. This section is written to the standard those athletes expect.

Can chiropractic help with concussion recovery?

Concussion is a brain injury and is treated as one, with graded return-to-play and a team around the athlete. Functional neurology examines the systems a concussion disrupts, including the vestibular system, eye movements and autonomic regulation. The concussion lesson covers recognition, assessment, and recovery in depth.

What is heart rate variability and why do athletes track it?

Heart rate variability is the small beat-to-beat variation in heart rhythm, and it is one of the clearest windows into the autonomic nervous system. Higher variability generally reflects a body that is recovered and ready, while a sustained drop signals accumulated stress, which is why HRV has become a standard readiness metric in elite sport.

How is this sports section organized?

In five parts. Part one covers the athlete's nervous system, the foundation everything else rests on. Part two covers assessment and movement. Part three covers injury by region, rehabilitation, and return to play. Part four covers recovery, heart rate variability, and fueling. Part five covers the whole athlete, field care, and the standard of care at the highest level.

Where should an athlete or trainer start?

Start with part one to understand why the nervous system sets the performance ceiling. Start with part three if you are dealing with a current injury or a return-to-play decision. Coaches and trainers building a season usually want part two for screening and part four for load and recovery.
