I love tennis; it’s a great sport. But studies like the above should be used as a prime example of why correlation is not causation. The most obvious explanation for the result is that the analysis does not control for income: richer people are more likely to play tennis and have better health care. This does not mean that tennis CAUSES the longevity.
The study did control for socio economic status and also it is a study from Denmark, which generally has less inequality than the US. Obviously no observational study is conclusive and I definitely would not recommend taking up tennis solely based on this study. But given all the other research about social ties being important as people age, there is certainly a plausible causal pathway that a sport that is both social and gives you a cardio workout would be better than a sport that is a cardio workout and can easily be done alone.
