Stridalyzer Updates: Are you a “5-Star Runner”?


The “5-Star System”. Comprehensive Running Form Analysis. Simplified.

Defining a good running form is not Rocket Science, but it’s still extremely subjective. However, most experts agree that good running form is key to better performance and an injury-free running experience. And they also agree that the five fundamental vectors – Cadence, Ground Contact Time, Foot Strike, Body Balance and Impact Stress – form the key to good running form.

Stridalyzer Smart Devices, coupled with Stridalyzer Analytics and guidance solutions, is the ONLY solution that measures, analyzes and provides you an insight into all these vectors, and provides a proprietary rating system, that we call the “5-Star System“. This system was developed with feedback and guidance from veteran runners, coaches, trainers, sports physiotherapists and orthopedic doctors.

When you run with Stridalyzer Insoles or PODs, at the end of every run, Stridalyzer App works with the cloud-based Analytics system to analyze your entire run for the 5 areas, and provides a rating to each area:Activity_summary_iOS_alt

  • Cadence: Are you taking the recommended number of steps per minute – about 160-180?
  • Ground Contact Time: The lower your GCT, the better, as that means you are utilizing the knee & hip spring action optimally.
  • Foot Strike & Stance: While heel strike in itself is not a big problem, if your heel strike tends to cause you to overstride, that’s a concern.
  • Body Balance: Stridalyzer detects the load distribution on each leg, and calculates the avg. distribution throughout the run. Needless to say, a disbalanced loading will increase injury risk on the leg that’s overloaded.
  • Impact Stress: Stridalyzer senses and measures impact stress through out your run. A uniformly distributed stress pattern ensures no part of the leg is taking undue burden, as excessive loading on any one area increases injury risk significantly.

If you score a rating of 4 and above – you’re doing good! Otherwise, you might want to look into our guidance and recommendation for fixing some of the issues!

Diagnosing Running Form failures using “Action Replay” in Trainer’s Toolkit

Stridalyzer Trainer’s Toolkit enables coaches, Sports physiotherapists and doctors to help their clients in a much more intelligent way than by just using a short-duration gait-analysis in their clinic on a treadmill. Most running form problems show up much later in a person’s run when fatigue starts setting in. With Stridalyzer Smart Insoles constantly monitoring the runner’s form and uploading the data to the cloud for review, trainers and caregivers now have a much more powerful set of tools to diagnose what kind of running form issues the runner might be getting into and how it would affect the runner in the future.

Using the “Action Replay” feature on Trainer’s Toolkit (available through http://stridalyzer.retisense.com), caregivers can view down-to-the-minute stress-distribution on feet and knees, and pin-point the form-related lapses as well as when and why they occur.

This then helps the trainer recommend targeted solutions, like strengthening & flexibility exercises.

#RunBetter Tip: Why the Big Toe is such an important aspect of your running form?

“For several reasons, be it injuries or even minor running form issues, problems with the big toe can cause a chain reaction of problems on up the leg—from plantar fasciitis to Achilles problems to calf strains and more.” writes Ryan Wood of Competitor.com.
