Running Gait Analysis Is Not Running Retraining
Measurements produce data. Analysis and retraining require a defined model.
The clinical value of gait data depends on the framework used to interpret it. Before any measurement can support technique analysis or running retraining, there must be a defined model of the running movement itself.
Measurements Produce Data
Running can be measured in many ways: cadence, stride length, joint kinematics, foot-strike pattern, vertical oscillation, ground contact time, ground reaction forces, loading rates, and other variables.
These measurements can identify differences and changes in the variables being examined.
A measured value can show that something differs, increases, decreases, or changes under a particular condition. But the measurement itself does not establish what that finding means within the running movement.
That requires analysis.
Analysis Requires a Model of Running
Analysis begins when measured or observed information is interpreted against a defined model of running movement.
Without that model, it is possible to document differences, compare conditions, identify correlations, or establish that a variable has changed. It is not yet possible to determine whether the observed movement represents correct execution, a technical error, a compensation, or a consequence of another error.
A model provides the reference required to ask:
- What should the runner be doing?
- What should occur during support?
- In what sequence should the movement occur?
- Where does the observed movement depart from the model?
- Which deviation is primary?
- Which observed changes are consequences of that deviation?
Only then does collected information become technique analysis.
The model is therefore not an optional layer added after measurement. It is the framework that gives the measurements technical meaning.
RETRAINING REQUIRES THE SAME MODEL
Running retraining begins from the same model used for analysis.
Once a deviation from the defined running movement has been identified, retraining is the process of correcting that deviation and teaching the runner to reproduce the movement more accurately.
The same model must guide both analysis and retraining.
CHANGING VARIABLES IS NOT THE SAME AS CORRECTING TECHNIQUE
Running research often examines what happens when one or more measurable variables are deliberately changed. Step rate may be increased. Foot-strike pattern may be altered. Trunk position may be adjusted. Several variables may be manipulated at the same time.
The resulting changes can then be measured.
This is useful for understanding how selected variables interact and how their manipulation affects loading, joint motion, stride parameters, or other biomechanical outcomes.
But successfully changing one or more variables is not the same as correcting running technique.
A variable-based intervention and a model-based correction follow different logic:
Variable-based:
Select a variable → prescribe a change → measure the result
Model-based:
Define the running movement → analyze the runner against the model → identify the technical error → correct the movement → reassess the movement → measure the resulting changes
Measured variables in running are interdependent because they arise from the same movement. Changing one measured variable may alter several others, including changes that were not targeted, expected, or desirable.
| Variable-Based Approach | Model-Based Approach |
|---|---|
| 1. Starts with selected variables | 1. Starts with a defined model of running movement |
| 2. Focuses on changing selected measured variables | 2. Focuses on changing the running movement |
| 3. Uses individual variables as intervention targets | 3. Uses the model to determine what should change and why |
| 4. Determines whether the targeted variable changed | 4. Determines whether the running movement changed in the intended way |
| 5. A targeted change may alter other variables in unexpected and not necessarily desirable ways. | 5. Correcting the running movement will produce corresponding changes across multiple variables without prescribing them individually. |
Running movement improves when the identified technical error is corrected and the resulting movement changes in the way predicted by the underlying mechanical model. Measured variables may change as consequences of that correction.
Changing a targeted variable alone establishes only that the variable changed.
What Constitutes a Model of Running?
A model of running is more than a collection of measurements, preferred ranges, biomechanical targets, or corrective cues.
It must define the running movement itself and explain how its essential elements relate to one another.
A complete model should provide:
- a definition of the running movement;
- the essential elements of that movement;
- the relationships among those elements;
- the sequence in which the movement occurs;
- a standard against which execution can be analyzed;
- criteria for identifying technical errors;
- a basis for distinguishing primary errors from their consequences;
- a method for correcting and reassessing the movement.
Cadence, foot-strike pattern, joint angles, vertical oscillation, loading rates, and similar variables can provide information about running. They describe measurable aspects of the movement.
Combining several variables does not turn them into a model.
A model must explain how the movement is organized, why particular deviations occur, and what must change to correct them.
A MODEL-BASED APPROACH TO RUNNING
Pose Method® of Running is a defined mechanical model of running movement.
The model explains what occurs during running: how the runner interacts with support as gravity acts on the body, how the runner moves from one support to the next, and how the repeated sequence of the Running Pose, Falling forward, and Pulling the support foot back into the Running Pose produces continuous running movement.
That same model provides the reference for analyzing movement, identifying technical errors, correcting those errors, and reassessing the runner.
This creates a continuous process from observation to correction rather than treating individual gait variables as independent targets.
Measurements remain useful for documenting what changes. The model determines what those changes mean.
WHY THIS MATTERS CLINICALLY
Technical errors in running movement affect how support and loading are organized repeatedly with every step. Understanding the relationship between technical errors and common running-related injuries is therefore an important part of clinical running analysis.

Learn to Apply the Model
Understanding a model is different from being able to apply it.
Clinical application requires learning how to observe running movement, identify technical errors, distinguish primary errors from their consequences, select appropriate corrections, and reassess the runner using the same framework.
