Charles Linden and TRT™ Therapy have been the subject of sustained mainstream media coverage for over two decades — recognised globally as the authority on permanent anxiety disorder recovery.

The Scale of the Crisis

Anxiety in elite sport. The numbers are stark.

Anxiety disorders are the single largest unaddressed performance variable in professional sport — and the only one with a permanent, proven solution.

The Science

Why standard interventions fail. Why TRT™ doesn't.

Every conventional anxiety intervention — including CBT, medication, mindfulness, and counselling — has the same fundamental flaw: it treats the symptoms, not the cause. Anxiety disorders are caused by a chronically over-sensitised amygdala. Until that is recalibrated, the disorder persists.

What athletes are offered — and why it doesn't work

CBT (Cognitive Behavioural Therapy)Manages — never resolves

Rewires thought patterns around anxiety but leaves the amygdala's threat baseline completely untouched. The disorder returns the moment an athlete stops applying the techniques — which is precisely when they are under competitive pressure.

SSRI / Antidepressant MedicationDependent and performance-impacting

Suppresses emotional responsiveness system-wide. No neurological resolution. Athletes face blunted reaction time, impaired competitive edge, and full withdrawal effects on cessation. Not a performance-compatible solution.

Mindfulness & Sports PsychologySurface-level — no mechanism

Reduces perceived stress temporarily but provides no physiological pathway to recalibrate the amygdala. Optimising performance on an anxious nervous system is like upgrading the tyres on a car with a broken engine.

Counselling & Talking TherapyUnderstanding without neurological change

Helps athletes process and understand the origin of their anxiety. Does not rewire the amygdala. Athletes finish therapy with better insight into a disorder they still have.

The TRT™ approach — science into practice

Fear learning, threat appraisal and persistent avoidance are central to the anxiety cycle. TRT™ Therapy turns that science into structured psychoeducation and practical recovery work for athletes.

Fear-response science in practice

TRT™ Therapy works with learned threat responses, attention and avoidance through structured behavioural guidance and participant practice.

A practical recovery programme

Athletes learn to recognise the patterns sustaining fear and put recovery practices into their training, competition and everyday lives.

Measured programme outcomes

An NHS Shropshire-partnered evaluation of 61 participants recorded mean GAD-7 scores falling from 18.28 to 2.84 — an 84.5% mean reduction. The researcher was affiliated with Kingston University and the University of Copenhagen.

Organisational business case

The Institute's institutional record also includes a 2015 CAPITA business case examining NHS-scale delivery and potential system savings. That organisational work is distinct from the participant outcomes evaluation.

TRT™ is the only approach that treats the cause. Every other intervention treats the symptoms.

What Elite Athletes Say

Recovery in their own words.

"

This method is the way forward. Science-based, factual, and it just works.

"I had really bad health anxiety for a year, but the program showed me how to heal quickly. This process leads to a genuine recovery — you will 100% and quickly get fully over what's holding you down."

Rory Gibbs

2024 Olympic Gold Medalist — TRT™ Graduate
