Experts in breast and bra science

Our research helps women get the perfect bra fit and find sports bras that support their movement

 

We, the Research Group in Breast Health, use our expertise in breast biomechanics to improve scientific knowledge of breast health, inform the development of breast related products and raise awareness of this important aspect of women’s health.

Our research group is responsible for many international scientific publications in the area of breast biomechanics, bra science and breast health, and we have achieved considerable press coverage. Many of our collaborations are with the world’s major lingerie and sports apparel manufacturers. Ultimately, this helps us to achieve our overall objective of improving women’s quality of life.

Research

Our research group investigates an extensive range of topics related to breast and bra science.

Understanding appropriate breast support

Our research focuses on establishing appropriate breast support for different populations, environments and activities. Understanding how breast support preferences and requirements change over the lifecycle is crucial to offering appropriate solutions to women throughout their lives. Our research is at the forefront of methodological developments in this area.

This enables us to investigate:

  • Support provided by different bras.
  • Breast support requirements during different activities - walking, running, swimming, aqua aerobics, agility tasks, jumping, climbing stairs, lifting etc.
  • Thermal responses to wearing a bra.
  • Factors that influence support requirements throughout a woman's life.

Breast support for different occupations

Historically, high support bras have been designed for short duration, high intensity activities, such as running. Therefore, it is not known if these bras are suitable for longer duration occupational tasks; much like those carried out by females in the Military.

Through our collaboration with the HQ Army Recruiting & Initial Training Command, they have implemented a sports bra fit and issue service, a fantastic step forward for female recruit health. However, bra discomfort is still an ongoing issue for this cohort, and can affect their ability to undertake basic training.

Therefore our work with the Army is continuing. This research has the potential not only to impact the current sports bra fit and issue service, but has wider implications for all females in physically demanding occupations.

Breast anthropometry

Our research in the area of breast and body size shows that the relationship between the two isn't as clear as originally thought. Clinicians make recommendations for women to lose weight to reduce breast size, but this may not always be appropriate. Our study showed that to lose the amount of breast tissue that's removed during surgery, a woman would have to lose 51 kilograms, or 70% of her body weight.

We have 3D scanning capabilities housed within our breast mechanics laboratory. This specialist equipment enables us to measure the breasts to calculate breast volume and breast position via the high resolution 360-degree images produced. These measurements are sensitive enough to detect breast changes over time, for example, throughout the menstrual cycle.

Breast biomechanics and sport performance

We have an ongoing collaboration with the English Institute of Sport and the British Olympic Association to deliver breast and bra education, bra fittings and bespoke bra development for Britain’s top female athletes ahead of international events, such as the Olympic and Commonwealth games.

Within our research, we have explored the potential performance effects of different levels of breast support. When women run in inadequate breast support, we have recorded:

  • Increased perceived exertion - suggesting exercise feels harder when breasts are not properly supported.
  • Increased upper body muscle activity - suggesting fatigue may be reached sooner.
  • Increased ground reaction forces - which may increase the risk of injury to the lower extremities.
  • Decreased stride length (by 4cm) - suggesting the wearer is hesitant to stride out. This could mean running an extra mile over the length of a marathon.

Breast computer simulation modelling

Our computer simulation modelling research has enabled us to answer some important questions not easily addressed in a laboratory. Our computer modelling team (led by Dr Chris Mills) has created a novel model of the female torso to highlight how the breast mass, position and motion on the chest wall can affect the loading on the spine and musculoskeletal system. 

The work uses a combination of medical imaging and complex computer modelling techniques to simulate the effect on the breast during a variety of movements. Early results concluded that neglecting the breasts and their position in female computer models may cause a misrepresentation of the muscular demands, by up to 18%. These findings have multiple applications, such as:

  • Effects of breast augmentation/reduction
  • Potential injury mechanisms in a variety of physical activities for females

Sports bra performance

Our work has informed the research and development of breast support garments for over a decade. Our recent study on sports bra performance has given us further insight into how specific sports bra characteristics may affect breast movement reduction. We found that over a third of sports bra performance could be explained by five key characteristics, where the presence of each of these characteristics increased the percentage of breast support provided:

  • Encapsulation style
  • Padded cups
  • Adjustable underband
  • Nylon (principle fibre content)
  • High neckline

These findings facilitate sports bra development and inform consumer choice.

Bra fitting

Over 80% of women have been reported to be wearing the wrong size bra, so an important area of our research focuses on breast sizing and bra fitting. It is crucial that women of all breast sizes wear appropriate and correctly fitting breast support for everyday activities and when exercising, as wearing the correct bra size reduces breast pain, and improves general health and wellbeing. 

In one of our studies, we identified that the traditional bra fitting method does not give the best fit. We advocate a series of 'Best Fit' criteria. We believe it is important to educate women on best fit, rather than using a tape measure to dictate bra size. 

Breast pain

We have strong links with our local hospital and breast clinic to conduct important research in the area of breast pain. Although exercise-induced breast pain is proposed to be linked to the stretch of the breast’s anatomical structures (breast skin and fascia tissue), the exact source of breast pain is still unknown.

We have investigated the prevalence of breast pain within the general population and found that 51.5% of the 1,659 women surveyed experience breast pain. These women tended to be larger breasted and less active. We have also reported high levels of breast pain in other populations we have researched, such as marathon runners and horse riders.

Bra testing services

Welcome to the research group in breast health at the University of Portsmouth.

We are world leaders in the area of breast biomechanics. We've been working in this area, investigating the performance of bras for over 12 years now. So we've built up a real database of information in this area. And we can work with you to help develop the best products.

In order to do that we offer different bra testing services: bronze, silver and gold. We also offer bespoke research packages.

Here we have our specialist breast biomechanics laboratory and this is where we test all of the products that companies send us.

Our testing is based on research that we've published in the scientific literature over many years of research in this area. Within our bronze, silver and gold bra testing packages we aim to assess the performance and breast support of sports bras and everyday bras. And we're able to do this by using our state-of-the-art motion capture technology.

We've got 2 main systems that we use within our bra testing. The first is our camera system and that tracks reflective markers which are positioned on the body and the bra. It's also really important to understand what's happening inside the bra and we're able to measure this using our motion sensor system. The benefit of this system is that the sensors can be placed directly on the breast beneath the bra to track breast movement.

We test the performance of each bra based on different activities chosen by you, depending on the function of the bra. Normally we test sports bras during running but we can also test everyday bras during daily tasks.

Our volunteers then repeat those activities but without a bra and this bare breasted activity acts as a baseline that we can calculate the percentage of breast movement that is reduced when they are wearing a bra. So this percentage of breast movement reduction, or bounce control, tells us how supportive a bra is.

We've got to a stage now where we've tested hundreds, probably even thousands of bra,s and the benefit of that is you can compare your products to the bras that we've already tested. Although these data are anonymised it gives a good indication of how your bras are performing against those that are already in the market.

Also within our bra testing we collect subjective feedback and that's on things like bra comfort support, breast pain. And that ties in really nicely with the breast breast biomechanics data to give you an overview of how the bra meets the needs of the consumer.

Lastly what makes working with us really unique is the feedback you receive from our experts. And we will offer recommendations on how products can be improved.

All of this is delivered within a written report and so that includes the breast biomechanics data, consumer feedback and recommendations from our experts.

Our state-of-the-art kit also allows us to produce slow motion videos which give a visual representation of how your products have performed.

Additional to the bra testing the bronze, silver and gold packages also offer other benefits such as consultancy days with our world leading experts.

Breast education for teachers

Adolescent girls can go through periods of self-consciousness, negative body image and low self-esteem. This happens at the same time as their first stages of breast development – the first outward sign of puberty.

In 2015 we surveyed more than 2,000 girls between 11 and 17 years old. We found that:

  • Few girls knew what sort of bra to wear, whether their bra was a good fit or how to avoid breast pain.
  • Three-quarters of girls had at least one concern about their breasts, such as embarrassment when getting changed for sport, breast bounce or breast pain.
  • More than 70% of girls wanted to know more about how to check for signs of breast cancer.
 

50-minute breast education presentation and lesson plan

Following extensive consultation with girls, teachers and schools we have produced Treasure Your Chest, a breast education presentation and lesson plan to help you teach adolescent girls about breast health. This is free to download from our Treasure Your Chest website.

The Treasure Your Chest presentation aims to improve girls' breast knowledge, confidence and breast health habits and covers the following topics:

  • An icebreaker to tackle the embarrassment of talking about breasts
  • Understanding the anatomy of the breast
  • Why some girls may suffer breast pain and why girls need a bra
  • The bra fitting process
  • Things to look out for when buying a new bra
  • Breast sizes and shapes
  • Breast awareness
  • Looking out for breast cancer

The resources also include detailed learning outcomes and background information so teachers can answer any questions they might get on the topics.
