What Runeasi measures

Run assessments

How well you control unwanted side to side motion at the pelvis while running. Better stability means less wasted energy and a lower injury risk.

Compares the load on your left and right legs to reveal imbalances that can lead to overuse injuries or hold back performance.

The size and speed of the impact forces that travel through your body every time your foot hits the ground.

Jump assessments

Reactive strength index. How quickly and explosively you turn a landing into your next jump.

Your jump height combined with the time it takes to produce it, for a complete picture of explosive power.

How well your legs store and reuse elastic energy during ground contact, working like a spring.

Run Assesments:

  • Impact loading: Measures how much load your body experiences (impact magnitude) and how efficiently it absorbs it (impact duration).
  • Dynamic stability: Measures the side-to-side movement of the hips and provides insight into your ability to stabilize them.
  • Symmetry: Indicates how evenly the left and right legs perform across key biomechanical metrics.

Jump assesments:

  • Jump RSI: Measures reactive and explosive power, and is a key indicator for performance and return to sport.
  • Height and contraction time: Measures power output and how quickly you jump.
  • Spring efficiency: Indicates how effectively energy is transferred from braking to propulsion, reflecting your use of elastic energy.

Looking at how the runeasi sensor presents data

COMBINED RUN & JUMP TESTING FOR IN-DEPTH INSIGHTS

Runeasi combines running gait and jump testing in one tool for full-spectrum assessment.  This provides a holistic view, allowing professionals to identify strengths and deficits at every level. 

Running mechanics in a single, easy‑to-explain report.

TEST

Use live treadmill feedback, outdoor runs, and increasing speed tests to capture running mechanics

ANALYZE

Identify loading patterns, stability, asymmetries, and how fatigue or speed changes affect gait quality over time. Also ideal to track progress in return-to-sport.

PRESCRIBE

Strength training, (rehab) exercises, gait drills, (live) gait retraining feedback, as well as running volume, intensity, and pace zones can all be adjusted based on objective thresholds, ensuring safer progression and more efficient running.

Explosivity assesses your client's neuromuscular capabilities. How quickly can they generate force? This is a key quality for athletic performance and successful return to sport.

TEST

Perform a Squat Jump and Countermovement Jump in just 2 minutes.

ANALYZE

Measure power, rate of force development, and elastic performance.

PRESCRIBE

Optimize training by identifying the key physical qualities that need improvement for a safe and successful return to sport and performance training.

Reactivity assesses your client's ability to rapidly absorb and reproduce force through the stretch-shortening cycle, one of the most important qualities in sports performance.

TEST

Perform Repeated Jumps and Single-Leg Repeated Jumps in just 2 minutes.

ANALYZE

Measure reactive strength, elasticity, reactive stability, and inter-limb asymmetries.

PRESCRIBE

Tailor plyometric training based on key insights to support an optimal return to sport and maximize athletic performance.

A full library of exercises

Runeasi has built an extensive exercise database, ranging from stability work, to strength, and to plyometric training. These exercises are designed to support clients from beginners to high-level athletes and are fully integrated into our training recommendations contained in the reports.

NO COMPLEXITY. JUST CLARITY.

Runeasi is an advanced running gait and jump analysis software that uses a high-end IMU sensor worn at the body’s center of mass (lower back). The technology measures impact forces and the response from the musculoskeletal system to these forces. Data is processed in real-time, providing objective insights to make better clinical decisions and enhance your services. Results are presented in client-friendly reports, enabling more individualized care.
