Because it is running by analysis

Most of you know it because you would have tried it in a running store, administered by a well-meaning shop representative who would then match the results to a pair of shoes presumably perfect for you that will help keep you injury free.

Gait analysis provides runners with essential information about their running style. This is important however long they have been running, as only through knowing their running style will they be able to select the right shoes.

The right running shoes are important as they can maximise both running performance and potential, as well as minimising the risk of injury, such as painful shins and joints. The major focus of gait analysis is to measure the degree of pronation. Pronation is the natural inward roll of the foot as the outside part of the heel strikes the ground.

This roll acts as a shock absorber for the leg and body, Video gait analysis is simple. The first assumption being that your foot strike is somehow a natural unchangeable phenomenon that can be fixed by applying the correct shoe.

This assumption is wrong: Can shoes fix it? Sadly, gait analysis cannot measure the natural roll of the feet because a it is usually not conducted barefoot and b the majority of runners tested are not adopting a natural running gait anyway.

Gait analysis only video records your feet not the entire body. This is similar to recording a bowling ball striking the pins but not stance, steps and throw leading into that result.

Would you feel confident telling someone how their throw is from just a recording of the end-result how the ball hits the pins?

We also need to accept the raw reality of the current injury crisis: Yet the crisis remains and statistics continue to be depressing to read. No matter what your reasons, if you are doing something and it is not effective, it is time to consider a new approach: Gait analysis out, running technique analysis in So what to do?

The real solution is very simple, and anyone with a portable camera supporting 60 frame per second slow-motion playback can execute the first part of it.

You film someone outdoors or on a treadmill, from the side, and you film them both in their regular pair of shoes and barefoot. Because the second part of the solution is harder — interpreting what you see on the video and prescribing the right corrective actions.

CE Squad runner Amidou filmed on the uphill. Now cut away all but the feet and draw your conclusions. This cannot be done in ten or twenty minutes, nor can it be done beyond the very basic intervention in an hour. It requires great skill and experience on part of the person looking at the video which includes a full understanding of biomechanics, the laws of motion and human movement.

But this is the direction the running store industry needs to move towards. Traditional gait analysis has to disappear from running shops everywhere and be replaced by a full video assessment, a basic introductory session to get the runner on the right track straight out of the shop or as close to it as possible and then recommendation for follow-up work.

Some people will require significant work, four hours or more, before they are technically at the level they need to be at to run enjoyably and injury free in their new footwear or barefoot if they prefer.Correct and effective video analysis of running technique requires the right setup, and a clear concept.

After an ANOVA has been run in factors with more than two levels we cannot fully understand where the differences lie without post hoc tests.

Reliability Analysis It is very common in psychological research to collect multiple measures of the same construct. For example, in a questionnaire designed to measure optimism, there are typically many items that collectively measure the construct of optimism.
