just curious how many of you guys use overspeed training, and if you do what distance do you use also is there any benefits to doing overspeed starts vs. overspeed runs (30-60m)?

starts are about application of force and push, push, push so I don't see much benefit from overspeed starts. Only overspeed running I like is assisted or downhill on a reasonable gradient and for very short distances say 10-40m.

Participant
so theres no benefits to overspeed starts, my friend coach really like them and they seem to work for them..
-
Participant
i am really thinking about adding some overspeed stuff in as i start to taper, something like 3-6×30-50m.

Participant
They can teach the athlete to keep their lean longer due to a longer acceleration because velocity is increased. The acceleration caused by going overspeed in assisted or downhill running provide the same benefit. I just see no purpose when they can theoritically upset what you have done in regards to stride patterning and application of force in starts. Overspeed work is MaxV work not acceleration work.

I would think that assisted starts would make you stand up faster. Can you explain to me how it would help you stay down and keep the lean?
-
KeymasterIn general I'd suggest avoiding overspeed training because of the potential detrimental effects it can have on sprint mechanics. I've never used overspeed starts but I'd imagine it would have the possibility of covering up a lot of flaws that would still otherwise exist were the overspeed modality not used.

i really like overspeed work and have use both starts and full runs, but then again who am i..
-
Participant
Assisted means you are being pulled, If they are pulling they are moving your center of gravity forward, hence the lean. You can't accelerate and not have forward lean. If you are going overspeed theoretically you have greater momentum, thus you have a greater impulse with mass being a constant in both equation acceleration has to increase.

not saying ur wrong, just saying i have had great success with it.. saying that i wouldnt take a 13 yr and make them do overspeed work..
-
Participant
I just don't see the purpose of doing overspeed with starts. What you are trying to accomplish can be done without the starting part, because if you can increase maxV then acceleration should follow suit. Someone else is providing the force application which you are not and increasing the application of force aids acceleration not someone or something (gravity or treadmill) else doing it for you.

i only use the overspeed starts on meet days, but on mon i will do 4×30 overspeed/4xflys 30-30

I am not a proponent of overspeed training . . . once the bungee or tow is released stride length immediately returns to normal length. With the two components of speed being stride length and stride frequency, it has no significant affects on either.
Danimal said it already, in order to get faster, force application must be increased. Therefore heavy squats, cleans, and even resisted runs would be a more beneficial way of increasing power.

Just out of curiosity how do you do this. Do you set up a pulley system. Do you do it manually with a training partner?

What you've said is 99% correct but I think the main benefit / training stimuli to using towing devices is increasing the eccentric load at touchdown thus creating a situation where the athlete can increase their leg stiffness.
Having said that I'm no proponent of overspeed work as I think the cons outweigh the pros….I just figured I'd play devil's advocate a little.

I will take my 99% and run with it . . . not attached to any pulleys or towing systems.

i love overspeed for athletes that can handle it..

maxV runs with a weightvest would have the same effect, correct?

[/quote]No no no no no. MaxV runs with a weighted vest would cease to be MaxV runs. The vest would slow things down so dramatically that it could no longer be considered MaxV. This isn't to say that it couldn't have a purpose but it wouldn't really be to develop maxV in the strictest definition of the word.ELITETRACK Founder

sorry : P
i wanted to express that runs emphasizing maxV running mechanics (vertical force application while neglecting the acceleration part using fly-zones) while using wheightvests would have similar training effects than the increased eccentric load at touchdown when doing overspeed runs.
ill try to be more carefull in the future : ) -
Keymaster
You're probably right but I think it might be a little risky if volume crept up too high. The nice thing about sprinting is that as you get better you'll naturally increase the eccentric load because….as you get better it means you've started creating more vertical forces at ground contact, you'll get greater vertical displacement in flight, you'll experience greater loads upon landing.

I thin
so in the end the most important aspect is technique, as long as you run correctly speed development would take care of its self?
I think so. The faster you run…the harder it is on the body. That's why as athletes progress many times they can't handle the same volume of high CNS activities.
