Motion is lotion for the joints

I just heard a marathon runner, age 69, who started running because his father died at 55, say that on the radio show, "Doctor, doctor" EWTN. We know that obesity is a big factor in Covid deaths. What about sports? Are marathon runners doing better than joggers? Hockey better than tennis? Swimmers better than bikers? I did find research comparing athletes with couch potatoes in the Covid survival race. I get about 30 minutes a day.

 
Also, I learned that knee injuries are the most common for runners, but runners that land on the mid-foot have half the injuries.

 
Kaiser Permanente (California) did a study including 48,000 of its clients, not by type of sport, but by level of activity. "Even after correcting for all of those characteristics (age, sex, race, smoker, etc) , people who were consistently inactive had a significantly higher risk of hospitalization, ICU admission, and death after getting COVID-19 than those who were active for at least 150 minutes per week. Additionally, those who were active for over 10 minutes per week had some protection against severe illness or death from COVID-19 — though not as much as those who got the full 150 minutes. The highest rates of COVID-19 were among those who were Latinx: 65% compared to 18% (whites), 7% (Blacks), and 6% (Asian or Pacific Islander). It’s worth noting that people who were white were somewhat more likely to meet physical activity guidelines — a discrepancy that should be acknowledged and addressed."

So my friends (on Medicare), time to check to see if your insurance plan includes Silver Sneakers.
