Racquet sports may add years
New reporting on a 25‑year study suggests racquet sports like tennis and badminton are linked to the biggest longevity gains — in some analyses as much as a decade longer life — likely because they combine cardio, coordination, and social play. The coverage also notes that exercise timing matters for blood‑sugar control in people with diabetes, and that vigorous activity has been associated with lower risk of eight diseases over the following seven years, so the takeaways are: pick sustainable, social cardio and be intentional about when and how hard you train.

A 25‑year follow‑up of people in Copenhagen turned a casual conversation starter—“does tennis keep you young?”—into a striking headline: adults who reported playing racquet sports lived substantially longer than those who said they did no exercise, with tennis associated with an estimated 9.7 extra years of life compared with inactivity. (doi.org) That result comes from the Copenhagen City Heart Study, which enrolled about 8,500 people in the early 1990s, asked them which leisure sports they did, and then tracked deaths for up to 25 years while adjusting for age, smoking, and other background differences. (sciencedirect.com) Why would racquet sports stand out? The paper’s simple answer is that they bundle several beneficial things in one activity: steady aerobic effort punctuated by short bursts of high intensity, continuous demands on balance and hand‑eye coordination, and frequent social interaction when games are played with partners or teams. (doi.org) Those features map onto biological effects we can picture: aerobic work strengthens the heart and lowers blood pressure; bursts of intense movement train muscles to clear sugar and lipids more efficiently; coordination and balance stimulate brain regions that preserve cognition; and social play reduces loneliness, a known risk factor for early death. (europepmc.org) The study is observational, not a randomized trial, so it cannot prove that picking up a racket will literally add a decade to your life. The authors adjusted for many confounders, but people who choose tennis may also have unmeasured advantages—income, access to courts, or healthier diets—that help them live longer. (doi.org) Still, the pattern that social, skillful, partly high‑intensity activities show larger associations with survival recurs in other datasets, which makes the explanation plausible even if not definitive. (sciencedirect.com) Two other lines of recent research fit this picture by unpacking how timing and intensity of activity affect health. Analysts of a diabetes trial and observational cohorts found that people with type 2 diabetes had better day‑to‑day glucose control if their moderate‑to‑vigorous exercise happened in the afternoon rather than the early morning. (diabetesjournals.org) That finding echoes laboratory work on circadian biology: our muscles and hormones respond to insulin and fuel differently across the day, so the same workout can move glucose in opposite directions depending on timing. (diabetesjournals.org) Separately, a large study using wrist accelerometers and self‑reports in the UK Biobank found that the share of one’s activity that is vigorous—short, breath‑stealing bursts—predicts a lower risk of developing eight major conditions over the next seven years, from heart disease to dementia. (doi.org) The practical translation is concrete: a few minutes per day of harder effort appears to buy more protection than the same minutes spent at a gentler pace. Put together, these results suggest a commonsense prescription: choose activities you can do regularly that combine cardio, quick intense efforts, and social engagement. (doi.org) If you have type 2 diabetes, consider scheduling some of your exercise after lunch or in the afternoon to improve glucose control. (diabetesjournals.org) If you want maximal return for limited time, include short bouts that raise your breathing rate. (doi.org) The Copenhagen study’s most concrete number—the 9.7‑year estimate for tennis versus inactivity—remains a headline because it compresses many moving pieces into one vivid image: a sport that asks the body to run, jump, aim, think, and talk at once.
