I am studying a Masters Research in Exercise Science at Northumbria University in Newcastle Upon Tyne. I am looking for all of you endurance runners out there who would to participate in a study that could be potentially beneficial to the runner.

Purpose of Study

The bio mechanics of the lower extremity plays a role in overuse injuries. More recently gait retraining has become popular for the endurance runner, increasing stride frequency whilst decreasing stride length generally has shown to reduce impairment in runners and generally improve running efficiency. Running Economy defined as steady state oxygen consumption given at a running velocity is highly known as a predictor of running performance. The aim of the study is to analyse the acute effects of increasing stride frequency on running economy and predicted race time of a 10k event of middle and long distance runners.


First Visit

First test is a steady state incremental running test which entails three minute bouts of running with a rest period in between for a number of five to nine stages. Followed by a break of a minimum of 15 minutes. The second test is a maximum oxygen consumption test to measure your level of endurance performance. This test requires you to run on the treadmill at the speed dictated by the first test the gradient of the treadmill will be increased by 1% each minute remaining at the same speed until you reach exhaustion.

Second Visit

Steady-state treadmill running for assessment of running economy. Running at a self-selected stride rate and also an imposed stride rate of 180 steps per min. Which will be dictated by a metronome and will be videoed to determine the ability to remain with the pace.

For each of these assessments you are required to wear a heart rate monitor, nose clip, and a mouth facemask mouthpiece to measure running economy, oxygen and carbon dioxide levels.

Inclusion Criteria:

· Middle to Long distance runner

· A recent personal best time for a 10k.

· Male and female

· Age 18+

Exclusion Criteria:

· Specific injuries over the last twelve months

· Elite runners are not required for this study, however experienced runners is expectable.

· If you have been advised not to partake in exercise.

· Not able to run for a continuous period of 30 minutes.

· Runners with a stride frequency of 90 strides per minute (180 steps). (Your stride frequency will be tested).

The research will be performed at Northumbria University. The testing will take 1-2 hours on the first visit and approximately one hour on the second visit. I intend to schedule the bookings for the assessments around your lifestyle to the best of my ability.

If you are interested in participating in this study or have further questions please contact Tracy Macfarlane at

(I'm excluded; my 10k PB is 12 years old and at 10k race pace my stride frequency is bang on 180 steps per minute.)

Also excluded - 10k PB is quite a few years old and my running isn’t great at the moment. I’m very local to you though (am studying a masters in sport and exercise psychology at Northumbria!)

Have you posted on some of the local club Facebook pages? (Eg Tyne bridge harriers etc)

In a 10km my stride frequency is more like 200 :-)

I'm out

When are you looking to do the trials? A family member is at Uni at Newcastle and he might fit the bill for you, but obviously is only there in term time.

Got something to say?
