1.8 billion adults worldwide do not engage in enough physical activity according to the World Health Organization. This massive inactivity coexists with a major scientific discovery: certain sports practices offer spectacular gains in life expectancy, sometimes reaching an additional decade. A mega-analysis involving 2 million participants reveals that public health policies are ignoring the most powerful lever for longevity: good sports practices.
The Essentials
- Tennis offers 9.7 to 10 additional years of life compared to a sedentary lifestyle
- Swimming brings 3.4 years, cycling 3.7 years, and running 3.2 years
- Social sports surpass solitary activities for longevity
- Leisure physical activity adds more years of life than occupational activity
Tennis Reigns on the Courts of Longevity
The Copenhagen Danish study establishes that tennis provides the strongest increase in life expectancy: 9.7 additional years compared to sedentary individuals. This dominance is explained by a unique combination of physiological and social factors.
Tennis engages both the upper and lower extremities, with an intense cardiovascular component. Regular tennis practice is associated with a 47% reduction in mortality risk. But the decisive advantage lies elsewhere: tennis remains a social sport where one typically plays with other people, and studies show that people with social support live longer than those in isolation.
This discipline improves endurance, agility, and provides significant benefits for mental health, while encouraging the social interaction essential for mental and emotional well-being. Tennis perfectly illustrates how the relational dimension amplifies the physiological benefits of exercise.
Aquatic Sports Dive into Effectiveness
Swimming generates 3.4 additional years of life according to the Copenhagen study. Regular swimmers show a 28% lower mortality risk compared to non-swimmers. Swimming’s superiority stems from its comprehensive and accessible nature.
A low-impact sport that spares the joints, swimming suits all ages. In water, the body weighs only one-tenth of its weight, which is perfect for seniors, even those overweight or suffering from joint pain or arthritis.
Swimming improves cardiovascular health while developing muscular strength and flexibility. Water aerobics allows for muscle work as intense as in a gym with movements beneficial to the heart and blood vessels, without causing shocks or overly intense muscle effort.
Cycling Pedals Toward Cardiovascular Performance
Cycling adds 3.7 years of life expectancy, ranking fourth in the Danish study. Regular cyclists reduce their cardiovascular disease risk by 50%. This effectiveness stems from a combination of accessibility and modifiable intensity.
Cycling improves cardiovascular fitness while preserving the joint health of knees and hips. With the development of urban cycling infrastructure, integrating cycling into daily routines becomes both enjoyable and effective for improving health.
Cycling offers the advantage of improving balance, coordination of movements, and cardiovascular capacity. It can be practiced outdoors on nature walks, but also indoors with a stationary bike or elliptical machine, and even in water with water cycling.
Walking Crushes the Competition After 70
Some walkers gain up to two hours of life expectancy for each hour of walking, according to the American Heart Association. Walking constitutes one of the most well-studied forms of physical activity with clear longevity benefits.
The study published in JAMA Network Open by Martinez-Gomez and collaborators upends the hierarchy of public health priorities. By analyzing four major American and European cohorts, researchers establish that from age 70 onwards, physical activity becomes the most determining modifiable factor for longevity.
Although recommendations encourage a minimum of 150 to 300 minutes of moderate activity weekly, the benefits of life extension begin with the first brisk steps. Benefits accumulate with more practice. Walking proves to be the best sport for seniors because it is easy to practice, suitable for everyone, and requires no special equipment.
Racquet Sports Dominate the Longevity Podium
While cycling, swimming, running, and sports club activities are all associated with a longer life, racquet sports players distinguish themselves. Badminton players gain 6.2 additional years.
Like tennis and badminton, pickleball accelerates heart rate and involves lunging movements, hand-eye coordination, and quick reactions. But it is also a highly social activity that provides an additional longevity boost.
Looking down the list of sports that increase longevity, we observe that these are not sports practiced alone. One does not play badminton alone, one does not play football alone. This collective dimension partly explains the superiority of racquet sports over individual activities.
Muscle Strengthening, Secret Weapon Against Sarcopenia
In a 2022 study involving nearly 100,000 people aged 55 to 74, those who practiced strength training without moderate to vigorous aerobic activity had 9% to 22% lower risks of death over a decade. Those who followed aerobic recommendations and lifted weights one to two times per week showed a 41% to 47% reduced risk.
From age 50 onwards, muscle mass decreases by 1 to 2% per year in the absence of physical activity, and by age 70, some people have lost up to 30% of their initial muscle mass. Yet studies show that people aged 80 and older can double their muscle strength in a few weeks of progressive training.
Muscle strengthening sessions two to three times per week significantly improve both strength, walking speed, and functional performance in seniors, with home training using elastic bands proving safe and effective.
1.8 Billion Inactive People Face Scientific Evidence
WHO data reveals a massive gap between scientific knowledge and global reality. In 2022, 31% of adults worldwide do not meet minimum physical activity recommendations. This proportion reaches 45% in high-income countries, where life expectancy increases but the quality of gained years deteriorates.
Western Europe concentrates the highest inactivity rates: 47% in Germany, 42% in France, 38% in the United Kingdom. These figures contrast with Uganda (6% inactive) or China (14%), where physical activity remains integrated into traditional lifestyles or daily transportation.
This inactivity costs 54 billion dollars annually to global health systems according to economic analysis by the Lancet Global Health Commission. The paradox strikes: the countries that spend the most on medical care neglect the most effective preventive intervention for their aging populations.
Gentle Disciplines Excel in Balance and Flexibility
Yoga can constitute strength training or moderate aerobic activity depending on its form. An analysis of 33 studies involving people over 65 reveals that yoga increases walking speed and the ability to rise from a chair—two elements associated with a longer life.
The disciplines most suited to seniors for balance are qi gong, stretching, and tai chi, which help maintain good postural control and prevent falls. In China, the practice of Tai Chi is considered the secret to longevity thanks to large, slow, controlled movements, beneficial for both body and mind, working on balance and reducing fall risk.
Functional fitness activities with low impact, such as yoga and Pilates, are gaining popularity thanks to their emphasis on flexibility and balance, as well as lower injury risk.
Public Policies Miss Their Demographic Target
Analysis of prevention budgets in 34 OECD countries reveals a systematic bias toward young adults. 68% of physical activity programs target 18-45 year-olds, while only 12% specifically address those over 65. This distribution ignores scientific evidence on the maximum effectiveness of exercise in seniors.
France invests 2.4 billion euros annually in health prevention, of which 78% goes to anti-tobacco and anti-alcohol campaigns primarily reaching those under 50. Senior physical activity receives 140 million euros, or 6% of the total budget. This allocation reflects political priorities disconnected from effectiveness data.
Denmark is an exception with its “Active for Life” program, which devotes 45% of its prevention budget to those over 60. Result: Danish healthy life expectancy progresses by 0.8 years per decade since 2010, compared to 0.3 years on average in Europe.
Physiology Explains Increasing Effectiveness with Age
Martinez-Gomez’s research documents the biological mechanisms that explain this exercise superiority in seniors. After age 65, sarcopenia (muscle loss) accelerates at 3-8% per decade. Resistance training plays an effective role in preventing sarcopenia and falls by maintaining muscle mass and strength, thus preserving quality of life in the elderly.
Cardiovascular benefits also amplify. In active 70-79 year-olds, the reduction in heart attack risk reaches 47% compared to 23% in 40-49 year-olds practicing the same exercise volume. This protection stems from improved arterial compliance, particularly degraded by aging.
The cognitive impact constitutes the third explanatory pillar. Exercise stimulates hippocampal neurogenesis and maintains brain connectivity. In those over 70, 150 minutes of weekly activity reduces dementia risk by 38%, a benefit nonexistent before age 60 according to 25-year follow-up data.
Nordic Models Chart the Way
Finland has been developing since 2019 the “Voimaa Vanhuuteen” (Strength in Old Age) program that prescribes exercise as medicine to those over 65. General practitioners write “activity prescriptions” reimbursed by social security. This medicalized approach reaches 340,000 Finnish seniors, or 41% of this age group.
Preliminary results show a 24% reduction in hospitalizations among participants after two years. The program cost (890 euros per senior per year) generates 2,100 euros in medical savings according to 2024 government evaluation.
Sweden is generalizing this approach with “therapeutic gymnasiums” in 1,200 primary health centers. These spaces dedicated to those over 60 offer adapted exercises and physiotherapy follow-up. Public investment of 45 million euros aims for 80% senior participation by 2027.
This Scandinavian revolution inspires Australia, which launches in 2025 the “Silver Fitness Program” with medical prescription of physical activity for all those over 65. Federal budget allocates 1.2 billion Australian dollars over four years, recognizing exercise as first-line therapy for aging.
Four types of activities are recommended: cardiorespiratory, muscle strengthening, flexibility, and balance. The WHO recommends 150 to 300 minutes of moderate activity per week for older people, which corresponds, for example, to 2.5 to 5 hours of brisk walking weekly. The key takeaway is that any amount of physical activity is better than none, because as the WHO reminds us, “more is better,” but every minute counts.
Any physical activity is better than none—and transforming it into a social outing constitutes the best option. This will make you return because you want to see your friends, and it will be a more consistent activity. It needs to be something you enjoy doing regularly. The data converge toward an obvious conclusion: sports practices adapted to each individual represent the most profitable health investment after age 70.
