"Most high school running backs should be able to run close to an 11 second flat" You deal in too many top notch athletes to realize what an average starter is like. That's true at the top high schools. I would say average starting running backs in high school run a 11.6-11.75 at best. I ran an 11.50 w a 4.68 40 and could out run and catch most highschoolers when I played. A friends son ran 11.0 with a 4.55 40 and looked like a gazelle compared to 90% of the kids he went against. Then they played Aliquippa with multiple kids as fast or faster.
Was about to comment the same thing. There is absolutely no way that “most high school running backs should be able to run close to 11” - at least not if one means real, FAT times. (Sure - if you let some random parent of a friend hand-time them, maybe they can run 11.0… but it doesn’t mean much…) I would guess that the vast majority of NFL players cannot run sub-11 FAT.
Remember that talking about 100m times usually comes with the huge caveat that many times from HS are hand times, not FAT. You can easily give a kid (who is capable of 12.00 FAT) a “PR” of 11.1 if the race was hand-timed by parents. This is the same reason that 40 times don’t really mean that much, since they’re always at least partially hand-timed and you have no idea how diligent the timer was. Honestly the only 40 times that actually mean anything are the ones from the NFL combine, where at least there is a professional timer with no conflict of interest.
@@jameshegeman5660 yep also 100 yards not meters. But the hand timing was done at the bel air relays in 1979. Granted electronic timing is far superior. Many high schoolers are running mid to low 10s in the 100m. My time in the 100 yards (9.8) would have been about a 10.8 in the 100m..fast but not fast enough to compete with serious sprinters. However at 62 I am investing in electronic timing equipment and I’m pretty sure I can consistently run sub 5s in the 40 and sum 13 in the 100 meters. I’ll be posting vids soon.
@@duffyandrokane1125 I’m sure you are fast. Now - it is NOT true that “many high schoolers are running mid to low 10s in the 100m”. Every hand time, especially at the high school level, is automatically going to be about 300 milliseconds faster than the real time, due to the reaction of the timer. Additionally, there is a statistical issue: The high variance of hand timing means that when one runs a PR, that time is very likely to have benefitted from this variance. As an example, if a HS runner claims a PR of 11.00 by a hand time, but only ran it once, then it is very likely that the actual time was no lower than 11.50, and easily could have been as high as 11.80-11.90. (I know this news may be disappointing to many…) In order to be confident in a hand time, one would need to run very close to it repeatedly. For instance, if an athlete ran 11.2, 11.1, 11.3, 11.2 (all hand times by different timers) in 4 consecutive races (with no intervening slower times), then it is reasonable to conclude that the athlete is capable of 11.2 + 300ms = 11.50. (Again, you always need to add an adjustment for the reaction of the timer to the starter.)
I think semitendinousis is just the most linear muscle to cary the force to ground and more speed more linear. But the muscle size is just aid and obvoiously stronger can be more elastic, but not the source of the speed. I mean that it will trengthen anyways with speed training as the forces increase. I think this is more like slow down muscle that will allways becomeme strong enaugh but obviously plays major deal if U do too much speed training in too short time and it brakes. Tose other hamstring muscles obviously takes more weight in less linear acceleration? But interesting topic. 👌
And glutes to move the upper leg too(moves upper leg back). Lower abs also get worked(lifting upper leg), quads(lift lower leg). Hamstrings( moves lower leg backwards, like a curl)
This applies to sprinters. I’m interested in a fencing lunge. What principles can I derive from this? It wouldn’t be maximum velocity so much as sudden starting speed, as I would only be moving center of mass a few feet forward or back in a snappy burst. I’d like to cover 2 feet in 300 MS
@@robertvondarth1730 Unlike maximal velocity (which is limited by tendon & connective tissue stiffness), acceleration is usually limited by muscle fiber contractile speed/power. Therefore you would want to look into the work of Andy Galpin and other muscle physiologists, and learn about how to promote Type I -> Type IIa/x fiber conversions. (Contrary to popular belief, maximal velocity is mostly dependent on tendon & fascia properties, and NOT on muscle fiber types.)
thank you for putting respect on badminton. them dudes are athletes
62 years old 4.9 40yard dash. I’m training daily. This is great stuff. I need all the help I can get.
I hope I still have it.going like that at 62. I'm 38 and I can till dunk, so imho my body is handling aging well so far at keast

Aliquippa? you from hopewell or something?
@youngsuit no. My friends son played them a couple years ago.

BOM DIA PROFESSOR
So hamstrings??
And glutes to move the upper leg too(moves upper leg back). Lower abs also get worked(lifting upper leg), quads(lift lower leg). Hamstrings( moves lower leg backwards, like a curl)
Calves press onto the ground so that hamstrings can curl more harder to propel
Glutes ?

Did anyone get the answer ? Too much talking I just want to know which muscle and what exercises to do …
Hamstrings. Deadlifts ftw. I instinctively knew this from cycling.
