The Run Lab

POWERED BY PROMPT PHYSICAL THERAPY

real Run lab results

Stronger runners start with better data

Generic plans miss your limiter

Most strength plans for runners treat everyone the same. Your weak link is specific to you.

Small gaps add up

A 10% difference side to side repeats on every stride, for thousands of strides a week.

Feel only tells you so much

Force plates show how you actually produce and absorb force, so training targets what matters.

You deserve a plan built on your data, not a template.

Sample reports

See exactly what is holding you back

Pro and Elite runners get a color-coded profile. Each test is scored against endurance-athlete norms, both legs are checked for imbalances, and your top priorities are named in plain language. Below are three real runners.

The read

A strong, well-built runner. Six of seven force measures sit at or above target, and her jump and reactive numbers climbed double digits since the last test. The right hamstring is the one exception. It is the lone deficit, the lone red flag, and the only measure that went backward.

Top priorities

  1. 1Right hamstring strength. At 85% of target, and down slightly since the last test while the left side gained.
  2. 2Close the side-to-side gap. A 15.6% hamstring difference is the only imbalance over the line.
  3. 3Keep building power. Jump height is up 23.5%. The plan protects that momentum.

The read

A powerful athlete. Jump power sits near the 87th percentile, and she produces force fast. Maximal strength is the gap. Hip, knee, and ankle force in run-specific positions falls below college and elite track standards. The left hamstring is the clearest issue, and limited left hip extension adds to it.

Top priorities

  1. 1Left hip extension and spinal rotation. The left hip does not extend past neutral, and limited right spinal rotation restricts the end of each left stride.
  2. 2Hamstring strength and balance. Low overall hamstring force, with the left side 31% behind the right.
  3. 3Maximal strength. Raising force at the hip, knee, and ankle should lift her power and the spring she gets from her tendons.

The read

A solid strength base. Power and reactive numbers read low against a young endurance pool, but for his age they land around the 72nd percentile. The findings that matter most are a large single-leg gap and a weaker right hamstring. Gait video showed a stiff stride with limited hip extension. Closing these gives him the capacity to build mileage safely.

Top priorities

  1. 1Single-leg control. A 31% single-leg jump gap is the clearest deficit to close.
  2. 2Right hamstring strength. At 84% of target and 20% behind the left.
  3. 3Power and spring. Low-level plyos build reactive strength with no fall risk.
  4. 4Open the hip. Tight hip flexors limit hip extension. Mobility work restores a longer, smoother stride.
  5. 5A safe mileage build. Re-testing shows when his body is ready for the next step up in weekly miles.

How Run Lab works

Three phases. The same process we use with every runner, from first-time racers to state champions.

  1. 01

    Consult and assess

    We film your stride in slow motion, test force and strength on VALD force plates and dynamometers, and run a running-specific mobility and stability exam.

  2. 02

    Design

    We turn the results into a detailed strength, plyometric, and mobility plan built around your limiter and your race goals.

  3. 03

    Execute and perform

    You train through the Bridge Athletic app. We re-test and adjust so the gains keep coming.

Built for runners, not copied from a magazine

No pages of leg lifts. Every session follows the order we use with our competitive runners, so the hard work lands when you are fresh.

We work with your coach

Our focus is strength, mobility, and plyometrics. We also help adjust your mileage when your testing or an injury calls for it. Your coach keeps ownership of your running plan, and we coordinate with them so everything points toward your race.

  1. 01

    Dynamic warm-up

    Lunges, skips, and drills to get ready to run.

  2. 02

    Plyometrics

    Hops and bounds for stiffness and spring.

  3. 03

    Key strength

    The big lifts, trained heavy while you are fresh.

  4. 04

    Isolated strength

    Calves, hamstrings, and hips, the runner-specific work.

  5. 05

    Mobility cool-down

    Static mobility at the end, where it belongs.

Your plan, on your phone

Pro and Elite programs live in the Bridge Athletic app. Every session is laid out, every exercise has a demo video, and Elite runners message their PT right in the app.

Running is what we do

You want to race faster and stay healthy through a full season. We get it. Runners are the heart of what we do.

Run Lab questions

What is Run Lab?

Run Lab is the running assessment and training service at PROMPT Physical Therapy & Performance in Knoxville, TN. We combine slow-motion gait analysis, VALD force plate testing, and hand-held dynamometry, then build a strength, plyometric, and mobility program for your running.

Who is Run Lab for?

Competitive runners from the 5K to the marathon, including masters runners. It also fits runners coming back from injury who want to return stronger than before.

What happens during a running assessment?

We film your stride in slow motion, test how you produce and absorb force on VALD force plates, measure hip, knee, ankle, and hamstring strength, and run a running-specific mobility and stability exam.

How much does Run Lab cost?

Baseline is $150 for a 40-minute visit. Pro is $250 for an 80-minute visit with full testing, a results report, and a program. Elite is $695 for a 16-week program with a re-test and unlimited messaging with your PT.

Do you help with my running plan?

Yes. Our focus is strength, mobility, and plyometrics, and we help adjust your mileage when your testing or an injury calls for it. If you have a coach, we work with them and support their program rather than replacing it.

How is my program delivered?

Pro and Elite programs are delivered in the Bridge Athletic app, with a demo video for every exercise. Elite runners message their PT directly in the app.

Is the assessment done in person?

Yes. Force plate and strength testing happen in person at our Knoxville clinic.
