I used to be decent to good at numerous sports back in CT. Moved to a new city, started a business, got fat and didn't "compete" in anything that involved a ball or teams for almost 20 years, with the exception of an evening 9-hole golf league for couple of years.
At 62 I finally dropped some pounds this year, got to biking regularly and found an over-55 softball league so I'd have something where I could release pent up competitive juices.
Slowpitch is a sport I used to rule. I was told that "newbies" who hadn't played in a decade or two typically got injured right away and it was mostly hammies. I figured my hammies would be OK from the biking, but I made sure they were stretched out well before playing my first game.
Hammies were fine. Between fielding errant throws and trying to accelerate out of the batter's box I did pull both groins and twisted a knee first game. Took the next one off, wrapped up my legs like Mickey Mantle for the one after that, then pulled a quad and a calf. All the while I went a whopping 2-for-16 as I was hitting flatfooted and required a runner.
I went out an purchased an impressive collection of compression sleeves for various body parts. I healed with the help of some PT, came back, hit .700 in final three games while running for myself but now have a stress fracture in my outer ankle which I believe is from running bases.
Based on the amount and types of yardwork I do, I was not expecting a complete physical breakdown from frigging slowpitch softball. But damn. Every throw feels like I'm ripping years of scar tissue. God forbid I decide to dive for a ball... who knows what will break?
I've received from other players advice ranging from, "I do tai chi every morning" to "The secret is to never stretch a damned thing!" when asking about how they keep their atrophied muscles and arthritic joints limber and their brittle bones from breaking.
So what's you're secret for limbering up to play competitive sports at at least a competent level once you're past 60? What should I be doing this offseason to prepare for next year?
