“The science behind the champions”

< BACK

Barin Sports has officially partnered with Gabriela and Stefani Stoeva, the most successful badminton players in Bulgarian history and one of Europe’s most accomplished doubles teams. Known worldwide as the Stoevi Sisters, the pair has spent more than a decade competing at the highest level of international badminton.

The collaboration brings together elite athletes and a company dedicated to advancing sports performance through science and analytics; in other words, a natural partnership where champions recognize champions.

In the modern competitive landscape of professional badminton, the one factor that separates the good teams from the best is combining tactical analysis with specialized sport science research, assuring long and sustained success for athletes. The long and successful career of the Stoevi sisters only shows their determination to stand next to the best, which is exactly why this partnership with Barin is a match made in heaven.

The Stoeva sisters’ professional journey began at the Haskovo School Club, a foundational support system they still credit today. What started as a hobby transitioned into a serious career in 2006 following their first major victory at the Bulgarian Under-13 national doubles championship. This early success propelled them onto the national team by 2009, the same year they made their international debut at the Turkey International in Antalya.

To reach an elite level, the sisters moved to Sofia at age 15 before making a life-changing move to France in 2014. Under the guidance of coach Mihail Popov at the IMBC92 club, they transformed from regional talents into world-class competitors. This transition provided the tactical discipline and financial support they previously lacked. Popov refined their synergy, positioning Gabriela as a power hitter and Stefani as a defensive wall. By adopting a smarter, more confident playing style and embracing Paris as a second home, the sisters gained the endurance and mental toughness needed to finally challenge the world’s top-ranked pairs.

Facing stronger international opponents forced them to analyze their game more closely and move away from relying purely on power. Instead, they began focusing on strategy, discipline, and long-term consistency. This analytical mindset is exactly what connects with our approach here at Barin Sports, using data, technology, and sports science to help athletes train smarter and perform at their highest level.

Here is where the goals of the Stoevi sisters and Barin sports reach a meeting point. With the efficient tactical and biomedical analysis of the Barin Sports Pro, the pair is positioned to maintain and even surpass the technical level needed to beat the other competitors and reach the poll positions of the rankings.

In the modern sports landscape, fast sports analysis is as crucial as ever. That’s why this strategic partnership opens the door for more efficient training and ultimately reaching the top of the world standings once again: “Through Barin Sports we will have accurate data about our physical performance, and this will help make our training more targeted. In modern sports, the scientific approach and data analysis are very important because they help athletes develop more effectively and reach a higher level”.

The year 2018 marked the sisters’ transition into the global elite as their "Paris polish" finally yielded major breakthroughs. They shattered psychological barriers by defeating the world’s top Asian pairs, starting with a stunning quarterfinal victory over China’s former World No. 1s at the China Open. This proved their defensive resilience could overcome aggressive powerhouses on their own turf. Shortly after, they delighted their "second home" crowd at the French Open by toppling the reigning Olympic Gold Medalists from Japan. These milestone wins secured their first Super 750 silver medal and cemented their status as world-class competitors.

One of the clearest demonstrations of the Stoevi sisters’ resilience came during the 2022 German Open, in a match against the Chinese pair Chen Qingchen and Jia Yifan. Although the Bulgarian duo ultimately lost, the encounter became legendary in badminton circles for its intensity. The second game finished 30-29, which is the maximum possible score under BWF rules. This highlighted just how evenly matched the two pairs were. Many rallies stretched to 60-80 shots, turning the match into a true test of endurance, focus, and tactical discipline.

Matches like this highlight how important endurance and performance monitoring are in modern sports/badminton. Through Barin Sports 360, athletes gain access to detailed data about their physical condition and workload, helping them prepare more efficiently and maintain the level required to compete in the most demanding matches.

Today, the Stoevi sisters remain among the world’s leading women’s doubles teams. Entering the 2026 season ranked in the Top 10 globally and No.1 in Europe, they continue to represent Bulgaria at the highest level, by pushing the boundaries of European badminton and proving that resilience, discipline and teamwork can challenge the sport’s global elite.

Maintaining this level for more than a decade has required not only talent and determination, but also the ability to continuously adapt their training and preparation. In modern elite sport, athletes increasingly rely on scientific methods, performance monitoring and data analysis to stay competitive and extend their careers at the highest level.

The career longevity of the pair is outstanding and with one of the objectives of Barin Sports being prolonging the careers of professional athletes, this makes the collaboration a natural fit. Champions recognize champions, and Barin Sports will ensure the Stoevi sisters possess the data needed to become the best.
