Volume

Volume measures the size of your overall Force Portrait. Experienced runners often have lower volume levels because their technique is fine-tuned, so they don't use excessive forces in the three directions. As you improve your running technique, you'll notice your volume will become smaller while running at the same pace.

A smaller volume is related to better running efficiency.

Running Direction Symmetry

The Running Direction Symmetry measures the difference in the Running Direction Magnitude for the left and right gait cycles.

Increasing this score indicates that your left and right sides are evenly balanced, leading to more efficient running.

Vertical Symmetry

The Vertical Symmetry measures the difference in the Vertical Magnitude for the left and right gait cycles.

If you score lower, it may indicate that one side is absorbing more shock than the other.

Lateral Symmetry

The Lateral Symmetry measures the difference in the Lateral Magnitude for the left and right gait cycles.

An increasing score reflects better balance between your left and right strides.

Injury Diagnostics

Prevent injuries before they happen with in-depth diagnostics that highlight potential risk factors and guide corrective actions.
Hip stability icon.

Hip Stability

Hip stability evaluates the control and strength of your hips to maintain proper alignment.
Hip mobility icon.

Hip Mobility

Hip mobility measures the range of motion in your hips to ensure fluid and efficient running.
Braking icon.

Braking

Braking analyzes the deceleration forces experienced with each step to minimize impact.

Hip stability icon.

Hip Stability

Hip stability evaluates the control and strength of your hips to maintain proper alignment. Enhanced hip stability helps prevent injuries and improves overall running form.
Strength and control to keep pelvis steady during side-to-side movement.
Reduces risk of injuries like low back pain and IT band syndrome.
Low hip stability scale is good; yellow or red suggests the need for strength exercises.
Hip mobility icon.

Hip Mobility

Hip mobility measures the range of motion in your hips to ensure fluid and efficient running. Improving hip mobility can enhance your stride length and running efficiency, reducing the risk of injury.
Measures hip's backward movement (hip extension).
Limited hip extension can cause low back and hamstring injuries.
Keep the hip mobility scale low; yellow or red means more hip stretches and exercises are needed.

Braking icon.

Braking

Braking analyzes the deceleration forces experienced with each step to minimize impact. Reducing braking forces can lead to smoother runs and less strain on joints and muscles.
Backward force applied when running, like braking a car.
High braking forces strain body and waste energy.
Keep Braking gauge in the green range; yellow or red needs attention.
