I'm Devvratt. DevPerformanceLab is my personal portfolio — a place to gather my work, study, and ideas at the intersection of sports science, strength & conditioning, and applied research.

Before the lab coat, I was on the mat. I competed in judo and wrestling for ten years — earning a national gold in judo and several medals in wrestling. That decade of training, cutting weight, getting injured, and coming back is the foundation everything I think about in sport science is built on. I know what it feels like from inside the sport.

The work that interests me most starts with objective data — force-time analysis, movement screens, training load — and ends with athletes who can train, compete, and return from setbacks with structure rather than guesswork.

02 / Areas of Expertise

What I'm trained in.

— 01

Strength & Conditioning

Periodized programming for sport-specific demands, training age, and physiological profile.

— 02

Rehab to Performance

Studying the measured pathway from injury back to peak — bridging clinical and competitive demands.

— 03

Return to Sport

Criteria-based progressions where readiness, not timelines, drives the return.

— 04

Athletic Performance Testing

App-based force-time analysis, jump profiling, and movement diagnostics.

— 05

Conditioning & Energy Systems

Sport-specific energy system development for repeated efforts and competition durability.

— 06

Body Recomposition

Sustainable fat loss principles that protect muscle, manage fatigue, and fit a real life.

— 07

Hypertrophy & Muscle Building

Structured progression for size and strength — built on principles that drive elite performance.

— 08

Data Visualization & Monitoring

Turning training data into clear dashboards and reports that can drive decisions.

— 09

Neuromuscular Fatigue

Force- and time-based metrics applied to combat athletes — the focus of my master's research.

— 10

Movement & Screening

Visual and video-based assessment as the foundation for safer, smarter programming.

03 / Rehab → Performance

The seven-stage pathway.

Most rehab ends where performance begins. It shouldn't. The transition from clinical recovery back to competition is a structured progression — each stage built on objective criteria from the one before it. This is the framework I find most useful for thinking about return-to-performance work.

04 / Performance Testing

If we don't measure it,
we're just guessing.

Performance testing has been at the center of my study and applied work — and the field has changed. Validated mobile applications can now capture force-time data, jump metrics, and movement quality from a phone, without requiring a sport science lab.

From a baseline, training load can be monitored, fatigue tracked, and progress verified. The result is a transparent, data-driven picture — accessible far beyond institutional labs.

Featured Work

Investigating neuromuscular fatigue trends across four successive fights in elite Greco-Roman wrestlers using force- and time-based performance metrics.

A study examining how repeated high-intensity bouts affect force production, contraction quality, and recovery profiles in elite combat athletes — using force-plate and time-domain metrics to map fatigue accumulation across competition. The findings directly inform how I structure intra-tournament conditioning, monitoring, and recovery for combat sport athletes.

A note on this site

A personal portfolio.

This website is a personal showcase of my professional journey — academic study, applied work, and the questions I find most interesting in sport science. It is not a commercial service offering.

If you'd like to talk, the best way is a direct email. I read everything that comes in.
