For readers who enjoy a weekend match or a quick rally after work, new research from Oura’s data‑science team offers reassuring news. By examining anonymized data from adult members in eleven global markets over a one‑month period (July 17 – August 17, 2026), the study measured heart‑rate intensity, long‑term Cardiovascular Age (CVA) and overnight recovery indicators such as Heart‑Rate Variability (HRV) and Resting Heart Rate (RHR).
Most recreational players stay in aerobic zones
While tennis feels like high‑intensity interval training because of short bursts of rallying followed by brief rests, the heart‑rate time‑series tells a slightly different story. The Oura data showed little evidence that the average recreational player spends meaningful time in high‑intensity zones (Zone 4 or Zone 5). Short spikes do occur, but overall workout intensity remains predominantly aerobic.
Regular play narrows the cardiovascular‑age gap
Despite the modest intensity, the cumulative effect of playing tennis regularly appears beneficial. Across every market examined, tennis players exhibited a larger positive gap between their chronological age and their Cardiovascular Age compared with non‑tennis‑playing members during the same period. In other words, regular court time helped participants look younger from a cardiovascular standpoint.
Improved overnight recovery after matches
To gauge post‑match recovery, Oura compared each member’s sleep metrics after a tennis session with their personal 14‑day pre‑workout baseline. The findings indicated improvements in both HRV and RHR, suggesting that the body rebounds more effectively after a match. Better HRV reflects a more adaptable autonomic nervous system, while a lower RHR during sleep signals reduced strain on the heart.
What this means for everyday athletes
For community members who view tennis as a fun way to stay active, the data supports the sport’s reputation as a heart‑healthy activity. Even without reaching high‑intensity zones, the combination of aerobic exercise, quick directional changes and the social enjoyment of the game contributes to long‑term cardiovascular benefits and faster recovery.
The study was produced by Oura and reviewed and distributed by Stacker. While the analysis is based on aggregate, de‑identified data, it underscores how everyday fitness tools can illuminate the health impacts of popular recreational activities.
