Running a marathon is something that features on many people’s bucket lists, but if you’re a female, a marathon could be even longer than 26.2 miles.
A new study by Brooks Running and the University of Portsmouth has found that ‘excessive breast movement’ can cost women an extra mile when running.
In the study, the researchers used biomecahnical analysis to assess the effect of breast movement on a woman’s stride while running.
Their analysis revealed that this movement can shorten your stride by up to four centimetres (1.57 inches).
Over the course of a marathon, this means that women could be adding an additional mile onto their run!
Brooks Running explained: “Excessive breast motion during running can lead to discomfort during exercise and potential damage to the breast’s internal structures.”
According to the researchers, a well-fitting sports bra can help to not only lessen this movement, and reduce breast pain and sagging.
Professor Joanna Scurr, the head of the University of Portsmouth’s Research Group for Breast Health RGBH), explained: "Regardless of breast size, a well-fitted sports bra can make the world of difference to your workout, as well as your general health and wellbeing."
Despite this, research suggests that more than 70% of women wear the wrong bra size.
Dr Jenny White, from the RGBH, said: “The most common mistake is to wear the underband too loose and the cup size too small.
"It's important to advise women on the best fit, rather than using a tape measure to dictate their bra size.”
Based on the findings, Brooks has developed a new range of sports bras specifically for runners.
Brooks added: “The bras are available in various styles, with different straps and back designs. The goal is to help women completely forget about their bra and get in the zone during their run.”
