We are proud to partner with performance biomechanics and have Biostrain part-funded by Innovate UK competition awards.

The task:

To design and develop a connected device with app and web portal integration for measuring hamstring strength and muscle imbalances.

The USP is analysis
in the DFTZ…But
what does that mean?

The DFTZ specifically focuses on a unique element within a stride cycle, which is the period when both feet are off the ground, also known as the double float transition zone. The stride cycle is a sequence of movements that occur during one complete stride of running, starting from when one foot makes contact with the ground until the same foot makes contact again.

During the DFTZ, the body is in a state of flight, where neither foot is in contact with the ground. This phase occurs twice in each stride cycle, once when the trailing foot leaves the ground (push-off) and again when the leading foot is about to make contact with the ground (pre-landing). Analysing this transition zone can provide valuable information about an athlete’s running mechanics and overall performance.

Identifying the

Before Biostrain, there was a lack of products on the market that effectively target and engage multiple muscle groups with the correct and appropriate posture. Existing options predominantly focused on isolating the hamstrings, placing users in awkward and unnatural positions.

Early human factors considerations

By focusing on human factors from the outset, we were able to prioritise needs, preferences, and limitations of the end-users. We were also able to mitigate potential risks and ensure compliance with relevant regulations and standards.

But, why is it Important to analyse performance?


Muscle imbalances and asymmetries can potentially increase the risk of injury. Football players rely heavily on their hamstrings during running, sprinting, and changing direction, and any imbalance or weakness in the muscle could put them at a higher risk of strain or tear.

It can also serve as a valuable tool in identifying potential weaknesses and injury risks by comparing a player’s performance over time to their baseline. This analysis enables the detection of any deviations or declining trends, allowing players and coaches to address and mitigate these issues.

Behind the scenes we…

…Did healthy volunteer

We got feedback from ex pro investors and also partnered with a UK university to do an impartial study. The aim of this study is to correlate metrics identified as reliable and valid from Biostrain with sprint performance to determine the relationship between the force production characteristics and sprint performance. It was crucial to choose participants who are enrolled in a sports science program or a related course that actively engage in structured strength and conditioning training, and possess some level of experience in competitive sports.

…Designed for manufacture

Our industrial design team had to consider material selection, manufacturing techniques, and assembly methods. By collaborating closely with engineers and production experts, we strive to create designs that are easy to manufacture without compromising on functionality or quality. Our extensive knowledge of manufacturing techniques and technologies allows us to incorporate design elements that simplify production, reduce costs, and minimise waste.

Built data sharing platforms

Designing a data sharing platform involves striking a balance between security, functionality, and ease of use. A user-centered approach and iterative design process are essential to create a platform that meets user expectations and fosters seamless data sharing experiences.

… Demystified Complex Data: Simplifying Interpretation

By continuously analysing the users experience we were able to improve user understanding, enhanced decision-making, time and resource efficiency, increased accessibility, identification of key insights with effective communication and collaboration between players and coaches.

Designed and developed instructions for use

We designed and developed a comprehensive instructions for use. These instructions were crucial in ensuring user safety, promoting proper product usage, complying with regulations, minimising potential liabilities and presented well for better user engagement and understanding.


UI style guides

UI style guides are crucial for maintaining consistency, reflecting brand identity, improving collaboration and efficiency, and ultimately delivering a superior user experience. They play a pivotal role in the success of digital products and websites.
