Flats Vs Clips: Help collect the evidence

The benefits and drawbacks of flats and clipped pedals are a much discussed issue within mountain biking. The Centre for Sports Engineering Research at Sheffield Hallam University are undertaking a research project to compare the pedalling technique and the power output of flat and clipped pedal in an attempt to bring some further evidence to the argument.

We are currently recruiting participants for the study who are regular racers at either Elite or Expert level in downhill or Enduro. The participants need to be available in Sheffield for the testing over two days on either the 25th and 27th Feb or the 4th and 6th March where they will be required to undertake a multistage sprint test on an ergometer. This will be in the form of five 5 second maximal sprints with a rest period in between each sprint. An introduction to the equipment and procedure will be given on the first day of testing.

Data will be obtained from the output of the Ergometer which gives power output and pedal force measurements for the duration of the test. A camera system will also be used to track the lower limbs throughout each rotation. To aid the tracking of the hip, knee and ankle small markers will be placed on the joints. All equipment will be provided by the University including pedals and shoes. Subjects will need to bring in their own bikes to enable setup of the ergometer.

If you are available on the dates in Sheffield and would like to be part of the study please contact Tom Duncan directly on
