Males lose the EXPLOSIVE first step in their late 20's. It may not mean much in rec play but it makes a signficant difference at ATP level as shown by Fed, Nadal, Sampras, etc.
Correct. Research shows males gain speed until about 20, then stay steady, and start a gradual decline by late 20s. Of course if you did not train at age 20, then start, you may be faster later 20s. But a male who trains regularly is usually slower at 29 than he was at 20.
Females are even more drastic. If they train regularly from a young age they only increase in speed until about age 13-14, then flat line. They actually will gradually slow starting at age 19. Most parents of girls have no idea their girl at 14 may be no faster at 19, and then begin declining gradually over time. it blows their mind a bit.
The following book has detailed line graphs from years of tracking athletes.
when I was 40, I noticed, I couldn't change direction as fast, meaning when opponent hit in behind me when I was in full speed, I had hard time stopping and changing direction. that is probably biggest difference. and also the part about getting injured a lot more easily than when I was young. and I pretty much can't play without stretching out first.When I was 25-35 I was always faster than my opponents and could run everything down.
When I hit 39 I noticed I lost a first step and cannot cover the court like I used too. My speed is only above average right now.
Oh well, this was last year and I hope I dont get any slower for awhile.
