How long we live is influenced by many factors, and one of the most powerful among them is physical activity. But not all exercise is created equal. New research from a long-term observational study sheds light on how various leisure-time sports can dramatically affect life expectancy — with some activities adding nearly a decade to your life.
Published in British Journal of Sports Medicine, the study offers fresh insight into the link between sport, social interaction, and longevity. It comes from the Copenhagen City Heart Study (CCHS), a comprehensive investigation into health behaviours and outcomes among thousands of Danish adults.
The Study at a Glance: What They Did and Found
The CCHS followed 8,577 participants over a period of up to 25 years, starting in the early 1990s. These individuals completed detailed questionnaires about their participation in different sports and leisure-time physical activities. Researchers then tracked all-cause mortality to see who lived longer.
By applying sophisticated statistical models that accounted for confounding factors such as age, sex, smoking status, and other health variables, the team calculated the impact of various sports on life expectancy compared to a sedentary lifestyle.
The results were striking:
- Tennis players gained an average of 9.7 extra years of life
- Badminton players saw a 6.2-year increase
- Soccer participants lived 4.7 years longer
- Cyclists enjoyed 3.7 additional years
- Swimmers gained 3.4 years
- Joggers lived 3.2 years longer
- Calisthenics practitioners had 3.1 years added
- Health club attendees saw a modest 1.5-year gain
These figures show that engaging in certain sports can lead to widely divergent benefits when it comes to lifespan.
Why Some Sports Outperform Others
One of the most fascinating aspects of this study is the observation that sports involving more social interaction tend to correspond with the greatest longevity gains. Tennis and badminton, both inherently social and often played in pairs or groups, topped the list.
Experts suggest that this social element might contribute significantly to wellbeing and longevity. Human beings are social creatures, and activities that foster connection could help reduce stress, improve mental health, and encourage continued participation — all factors linked to longer life.
Conversely, activities like health club workouts, which may be more solitary or less socially engaging, showed smaller benefits despite offering physical exercise.
What Makes This Research Important?
This study stands out because it focuses specifically on the type of leisure-time physical activity rather than just measuring exercise volume or intensity. It helps answer questions that many people ask: “Is one sport better than another for my health?” or “Should I try to play tennis instead of just going to the gym?”
Knowing that some sports offer greater life expectancy benefits may motivate individuals to choose activities they enjoy and that also foster social bonds — potentially making fitness more sustainable and rewarding.
Moreover, these findings can influence public health policies by highlighting the value of community-driven sports programmes and encouraging environments where people can engage in group activities.
Observational Nature Means Caution Is Needed
While the findings are compelling, it’s important to remember this was an observational study, meaning it can show associations but cannot prove cause and effect.
Participants who chose certain sports might differ in other ways from those who did not — such as having better overall health, higher socioeconomic status, or healthier lifestyles beyond exercise habits. Although researchers adjusted for many confounding factors, some unmeasured differences may remain.
Also, the study population was Danish adults, so results might not generalise perfectly to other regions or ethnic groups.
Practical Takeaways for Readers
- Choose sports you enjoy and that involve social interaction: Whether it’s tennis, badminton, or a local soccer league, playing with others can boost both your physical and mental wellbeing.
- Consistency matters: Regular participation in these activities over time is key for reaping longevity benefits.
- Don’t be discouraged by your current fitness level: Many sports offer beginner-friendly options and opportunities to improve gradually.
- Remember any physical activity beats none: Even health club workouts add years to your life, though combining exercise with social engagement seems optimal.
- Consider your own preferences and circumstances: The best sport is one you are motivated to continue playing long term.
Beyond Just Exercise
The Copenhagen City Heart Study enriches our understanding of how not just moving more, but how we move, can influence our lifespan. It reminds us that human connection remains a vital part of health — even when it comes to longevity.
If you’re looking to add some years to your life while enjoying yourself along the way, perhaps it’s time to pick up a racket, join a team, or find a friend for your next game of badminton or tennis. Your heart — and your calendar — may thank you.
