Aim of the study: To compare if the risk factors associated with Medial Tibial Stress Syndrome (shin splints) differ between minimal footwear and conventional running shoes. Inclusion criteria: - Running in minimal footwear for more than 6 months - Running >8km a week - Injury free What will be tested? - Plantar pressure using pressure insoles during a 2min run on a treadmill. - Medial (inner) foot arch height. - Hip range of motion. When? One testing session lasting 45min in a biomechanics lab in Dublin City University beginning at the end Feb-March. Date and time can be arranged to suit (including weekends). Interested in participating? Contact firstname.lastname@example.org or message me privately here. I would greatly appreciate the support as it has been difficult to find minimal shoe runners in Ireland. I'm a final year student and this is my thesis so it is very important I get enough participants to get accurate findings. There is also a lack of research within the area of long term adaption to minimal footwear and the effects this may have on the development of medial tibial stress syndrome. If you run with others who wear minimal footwear or know anyone who does in Ireland please let them know of this study. I look forward to hearing back from anyone that is interested. Many thanks!
