The side-view recording provides dynamic information about stride mechanics and running efficiency.
Both analysis angles together improve recommendation accuracy by blending back-view alignment analysis with side-view movement metrics, giving a full biomechanical picture to match each runner with the right shoe.
Purpose
The side-view analysis includes:
Body Segments: Head, torso, arms, foot landing, front knee angle, back knee angle (heel kick).
Spatiotemporal Metrics: Speed, time of flight, ground contact time, duty factor, cadence, stride length, step length, running style.
Joint Angles: Knee, hip, and elbow angle graphs to assess movement and asymmetries.
Running Style: Classification into one of five styles (Bounce, Hop, Push, Stick, Sit).
Comments: Add notes to track progress and document analysis details.
Together, these parameters detect insights hidden from the back-view alone, and help identify the optimal shoe model a runner benefits from.
Key Segments and What They Mean
Metric | Description | Interpretation |
Foot Landing | Measures where the foot strikes relative to the body and how it lands. | Short stride = higher cadence and efficiency; |
long stride = more power but higher impact and potential overstriding. |
|
|
Torso Lean | Degree of forward tilt from the hips upward. | A slight forward lean is optimal for efficiency; too much lean may indicate fatigue, too little can reduce propulsion. |
Front Knee | Knee angle of the front leg at foot landing. | A moderate bend absorbs shock effectively; too straight can signal overstriding, too bent may limit stride length. |
Back Knee | Degree of knee extension during the push-off phase. | Greater extension = strong propulsion and good hip drive; |
limited extension may indicate mobility restrictions or reduced power. |
|
|
Arm Flexion | Angle of the elbow during arm swing. | Consistent flexion stabilizes rhythm and reduces trunk rotation; excessive straightening or asymmetry can signal inefficiency. |
Head Position | Alignment of the head relative to the torso and forward direction. | Stable, neutral head position improves balance; excessive tilt or bobbing indicates compensations or inefficient posture. |
Key Metrics and Their Meaning
Metric | What It Measures | What It Means for the Runner |
Running Speed | Overall pace during recording. | Indicates the runner’s natural speed and how they load forces at different speeds. |
Time of Flight | Duration both feet are off the ground. | Higher values = more bounce and elastic energy use; |
lower values = more contact-heavy style. |
|
|
Ground Contact Time | Duration each foot remains on the ground. | Shorter = efficient, quick steps; |
longer = heavier loading or stability needs. |
|
|
Duty Factor | Ratio of contact vs. flight phases (measure of “aerial” running). | High aerial percentage = more bounce; |
lower = more ground contact, potentially higher impact. |
|
|
Step Frequency (Cadence) | Number of steps per minute. | Higher cadence = smoother, efficient stride; |
lower cadence = longer strides and higher impact. |
|
|
Stride Length | Distance covered between two steps of the same foot. | Long stride = power but higher impact; |
short stride = cadence-driven efficiency. |
|
|
Step Length | Distance between alternating foot placements. | Helps identify symmetry and balance between left and right sides. |
Running Style Category | Ochy’s classification of movement pattern (Bounce, Hop, Push, Stick, Sit). | Indicates how the runner loads and propels during their stride cycle. |
Joint Angles — What They Measure & Why They Matter
Joint angle graphs show how each joint moves throughout the running cycle. Ochy calculates angles based on the geometric relationship between two body segments connected by a specific joint.
They help identify running technique, mobility limits, and left–right asymmetries.
Joint Angles Table
Joint | What It Measures | What It Means for the Runner | How It Helps With Analysis |
Knee Angle | Angle formed between the thigh and the lower leg during the running cycle. | Shows how much the runner flexes and extends the knee (loading, propulsion, shock absorption). | Identifies overstriding, low knee drive, excessive flexion, asymmetrical loading between left and right. |
Hip Angle | Angle between the torso (pelvis-to-shoulder line) and the thigh. | Reflects hip extension (power) and flexion (stride efficiency). | Reveals mobility limitations, weak glute engagement, or imbalanced hip drive between sides. |
Elbow Angle | Angle between the upper arm and forearm as the runner swings their arms. | Indicates arm swing efficiency and rhythm. | Helps detect tightness or asymmetrical arm drive affecting overall balance and gait. |
Running Style
The Running Style section classifies the runner into one of five categories (Bounce, Hop, Push, Stick, Sit).
This style is determined by a combination of side-view metrics, including:
Time of Flight (how much bounce / aerial phase the runner has)
Ground Contact Time (how long they stay on the ground)
Duty Factor (balance between aerial vs. contact phase)
Step Frequency & Step Length (rhythm and stride mechanics)
By analyzing these movement patterns, Ochy assigns the style that best reflects how the runner produces speed, absorbs impact, and moves through the gait cycle.
Comments Tab
Right next to the Style tab, the Comments section allows staff to add notes or observations about the runner’s technique or recommendations.
These comments are saved with the analysis and can be used for follow-up, improvement notes, or internal store communication.
Staff Guidance
Use the playback video to show the customer how their stride looks in motion — this increases engagement and trust.
Always explain that both back- and side-view analyses help ensure the recommendation is as objective and individualized as possible with deeper biomechanical insights.
