Sebastian Korda posted a recovery score of 84% with a strain of 16.8 and a resting heart rate of 37 bpm following his match at the Oracle Challenger Series (OCR) today.
The data, shared via social media, offers a glimpse into the physiological demands placed on professional tennis players. Korda’s resting heart rate, notably low, is consistent with the exceptional cardiovascular conditioning often found in elite athletes. A study by Whoop, highlighted in Australian Golf Digest, found that golfers with lower resting heart rates performed better on the course, suggesting a correlation between cardiovascular health and athletic performance.
The Whoop data also indicates a high recovery score, suggesting Korda’s body is efficiently rebounding from the physical stress of competition. According to Whoop’s research, a 10-point increase in recovery score correlates to saving half a stroke per round in golf, demonstrating the impact of recovery on performance. While the study focused on golfers, the principle of improved performance through recovery likely extends to other sports, including tennis.
Sebastian Korda’s father, Petr Korda, was a professional tennis player, and his mother, Regina Rajchrtova, was a professional tennis player as well. His brother also plays professional tennis. A recent article in Tennis.com noted Korda following a win at Delray Beach. Stefanos Tsitsipas has also emphasized the importance of breathing techniques for athletic performance, according to a Tennis.com report from May 2021.
Alexandra Eala achieved a new career-high ranking of No. 31, and Janice Tjen became the first Indonesian woman to be ranked in the Top 40 since Basuki in 1998, according to rankings released today.
