Starting Strength: Training Log
Addresses distance running and the brother-in-law but what about sprinting? I would guess that sprinting increases strength but caps out at "X". Along those lines would lifting improve sprinting? A lot of it just seems to be a genetic gift, you are either fast in short distances or you are not. Just my guess, but don't know of any studies one way or the other.
Haven't heard this old chestnut in a while!
Rip looked pretty lean in the picture, though. Pre-SS I take it?
Generally, lifting will improve sprinting. There are many cases of young football players doing the linear progression, adding 100 lbs to their squat but not running, and then setting a personal record in the 40 yard dash afterwards.
As for why sprinting alone is not enough for building leg strength, there are several reasons, depending on how much detail you want to get in.
SHORT ANSWER FOR BROTHER IN LAW: The leg drive in a sprint or a jump doesn’t last long enough for full recruitment of the involved muscle mass, and it doesn’t keep that muscle under full load for a full range of motion, which is necessary for effective long term progress.
If the brother in law actually wants to learn things you could go into more detail on that and touch on other factors that make sprinting and jumping poor for strength gains such as:
1) Inability to carefully control the load as with a barbell
2) Difficulty getting enough effective volume since explosiveness drops off more quickly with fatigue than the ability to grind out reps.
3) Lack of eccentric loading which will limit strength gains
4) Higher impact on the joints due to ballistic components
I’m sure there is more, but that’s what I have off the top of my head.
Shouldn't that be 360 lb?Quote:
