The claim that playing tennis can add nearly a decade to your life has circulated widely in sports and wellness circles, often cited with eye-catching headlines. But how much of this is grounded in science and how much is oversimplification? As Editor-in-Chief of Archysport, I’ve reviewed the latest peer-reviewed research, consulted exercise physiologists, and traced the origins of these longevity claims to separate verified findings from promotional rhetoric.
The most frequently referenced source is a 2018 study published in Mayo Clinic Proceedings that analyzed data from over 8,500 participants in the Copenhagen City Heart Study. Researchers found that individuals who reported playing tennis as their primary form of exercise had a 9.7-year increase in life expectancy compared to sedentary individuals. This figure — often rounded to “nearly 10 years” in media reports — represents the strongest association observed among eight sports studied, including badminton (6.2 years), soccer (4.7 years), cycling (3.7 years), swimming (3.4 years), jogging (3.2 years), calisthenics (3.1 years), and health club activities (1.5 years).
What makes tennis stand out? According to Dr. James O’Keefe, a cardiologist at Saint Luke’s Mid America Heart Institute and co-author of the study, the sport’s unique combination of intermittent high-intensity effort, full-body coordination, and social engagement creates a potent trifecta for cardiovascular and neurological health. “Tennis requires constant decision-making, spatial awareness, and emotional regulation — all while delivering interval-style cardio,” O’Keefe explained in a follow-up interview with the American College of Cardiology. “It’s not just about raising your heart rate; it’s about challenging your brain and body in sync.”
This cognitive dimension is supported by neuroimaging research. A 2020 study from Southern Connecticut State University used fMRI scans to compare brain activity in experienced tennis players versus novices during simulated match scenarios. The players showed significantly greater activation in the prefrontal cortex and cerebellum — areas linked to executive function, motor planning, and emotional control — suggesting that long-term participation may enhance neural efficiency and resilience against age-related cognitive decline.
Yet, critical context is often missing from viral headlines. The Copenhagen study observed correlations, not causation. Players who choose tennis may already possess traits linked to longevity: higher socioeconomic status, consistent access to healthcare, lower smoking rates, or stronger social networks. As Dr. I-Min Lee, professor of epidemiology at Harvard T.H. Chan School of Public Health, cautioned in a 2019 editorial, “We cannot assume the sport itself is the direct cause. Active people tend to engage in multiple healthy behaviors — tennis might be a marker, not the mechanism.”
the life expectancy gain is relative to sedentary individuals, not the general population. When compared to those meeting minimum physical activity guidelines (150 minutes of moderate exercise weekly), the tennis advantage narrows considerably. A 2022 meta-analysis in British Journal of Sports Medicine found that while racquet sports conferred a 47% lower risk of all-cause mortality versus inactivity, the benefit over standard aerobic exercise was only about 18% — suggesting that any regular, sustained activity yields substantial returns.
Accessibility as well tempers the idealized narrative. Tennis requires courts, equipment, partners, and often membership fees — barriers that limit participation globally. In contrast, walking, running, or bodyweight exercises demand far less infrastructure. Public health advocates emphasize that promoting inclusive, low-barrier activities may yield greater population-level gains than focusing on niche sports, however beneficial they may be for those who can access them.
That said, tennis does offer distinct advantages for lifelong engagement. Unlike high-impact sports that often see participation drop after age 40, tennis accommodates adaptive play through doubles, modified scoring, and slower court surfaces. Programs like the USTA’s Tennis On Campus and the ITF’s Tennis Play and Stay initiative specifically target lifelong participation, recognizing that consistency over decades matters more than peak intensity in youth.
For readers considering tennis as part of a longevity strategy, the evidence supports realistic expectations: regular play contributes meaningfully to cardiovascular fitness, metabolic health, balance, and cognitive sharpness — all factors tied to extended healthspan. But it works best as one component of a broader lifestyle that includes balanced nutrition, adequate sleep, stress management, and routine medical care. No sport is a magic bullet; tennis is a powerful tool, not a standalone solution.
The next checkpoint for this research is the ongoing follow-up of the Copenhagen City Heart Study cohort, with updated mortality data expected for release in late 2024. Researchers plan to analyze whether initial sport choices predict long-term adherence and how changes in activity patterns over time influence outcomes.
If you’ve found this breakdown helpful in understanding what the science actually says about tennis and longevity, consider sharing it with others who might benefit from a clear-eyed view. Archysport remains committed to delivering sports journalism that prioritizes depth over sensationalism — because informed fans make better decisions, on and off the court.
