Cyclists wanted for TT research - Andy Brooke of Leisure Lakes , Breaston


16:04 Mon, 18 Sep 2017

Thanks for showing an interest in my research. Attached is a documents that outlines things in a little more detail but if you have any questions then please don't hesitate to ask.

Essentially, the study requires 4 visits, which will take just over 2 hours each. Each visit will follow the same protocol as outlined below.

Calf muscle strength test on the right calf
60 minute TT on your own bike
Calf muscle strength test on the right calf

Visits 1 and 2 will be 2-3 days apart, then there'll be a 4 week adaptation period to the new cleat position, with visits 3 and 4 then being 2-3 days apart as well.

I need 10-15 participants so please feel free to forward this email on to anyone that you think might be interested. The only criteria is that they're male, able to achieve around a 55-minute 25m TT and don't do any other sports that involve running.

Participant Information Sheet
Cleat position and joint kinematic changes during a 60 minute cycling time trial
• Brief Introduction:
Cleat fore-aft position is a key area of interest for both professional cyclists and amateurs looking to optimise their cycling position. The ankle plantarflexors provide little to no contribution to the forces required to turn the pedals, simply acting to stabilise the ankle to help transmit the forces being produced at the knee and hip. Shifting the cleat to a more rearward position may reduce the amount of calf muscles activation, reducing fatigue and potentially impacting how joint kinematics change over time. This study looks to explore those changes across two different cleat positions.
• Study Requirements:
You will be required to attend four different data collection sessions where you will be required to perform a strength test of your calf muscles (triceps surae) on an isokinetic dynamometer before, and after, completing a 60 minute time trial on a turbo trainer, using your own bike. This will occur whilst reflective markers and sensors are placed upon you and your movement and the associated muscle activation patterns are recorded. You will also have electrical sensors attached to key muscles to assess activation patterns during your cycling. It is estimated that you will be required to commit to a maximum of 12 hours of data collection over a maximum period of six weeks, although this will hopefully only be 4 visits at a little over 2 hours per visit.
• Location:
The Lee Westwood Sports Centre and the Biomechanics Laboratory, Clifton Campus, Clifton Lane, Nottingham, NG11 8NS.
• Restrictions During Testing:
You will be asked to refrain from strenuous physical activity for a 24 hour period prior to data collection sessions, and asked to train as normal over the 4-6 week period to ensure no significant drops in fitness.
• Testing Protocol:
Typically, you will attend a data collection session wearing tight fitting cycling clothing (e.g. lycra shorts and vest) and your cycling shoes. You will then be familiarised with the task of performing a strength test on the dynamometer before being asked to complete a 60 minute cycling time trial. We will attach 14mm passive reflective markers to specific anatomical locations on both your upper and lower limbs using double sided sticky tape. Skin preparation for the placement of electrodes will also be conducted which involves shaving the area of interest, lightly abrading the surface and then wiping clean with alcohol. This will be conducted at a maximum of 16 sites on the lower limbs. Finally, we will collect data every 5 minutes during your 60 minute time trial. This will be repeated over 4 visits. As you will be partially clothed, you will be offered changing facilities in order to prepare for marker placement and data collection.
• Potential Benefits to You:
You will gain a better understanding of both your ideal cleat position and your fatigue profile during a time trial, which could help identify areas to help you improve in the future.
• Potential Risks to You:
You may experience fatigue or tiredness associated with performing the activities of a 60 minute time trial. You are advised to bring along food and drink, and will be afforded generous rest periods (a few days) between tests in order to recuperate.
There is a small risk of a bad skin reaction to the double sided sticky tape and/or the EMG skin preparation. This will be tested on a small area and reviewed for a reaction. Participants will also be asked if they are allergic to plasters and must seek further clarification with regards to their participation with their GP if this is the case.
Although it is extremely unlikely, high intensity exercise has been known to reveal unsuspected heart or circulation problems and very rarely these have had serious or fatal consequences.
If at any point you decide to withdraw from the study your data will be destroyed.
