We know that the primary function of the hamstring during ground based locomotion is to extend the hip. Placing substantial load on it as a flexor of the knee, in my view, places a non-complimentary stress on it that when combined with the stress of high speed locomotion increases the likelihood of pulls.
This is the theory that makes sense in my system and I have a fantastic track record of hamstring health with my players during the times of year in which I have autonomous control over the entire training load.
It is not my intent to discourage others from performing GHR and hamstrig curls. To each his own.
I’m wondering if you could put this in some kind of context for the sprint community here.
By that I mean is there a point, in terms of distance, where certain exercises become more risky? I imagine some exercises are less risky if being done during a time which emphasizes 0-20 compared to max velocity work?
You are correct. As ESTI mentioned earlier, the dynamics of sprinting, from a muscular standpoint (specifically regarding the hamstrings) exist as:
start and early acceleration - lesser hamstring involvement
as the upright position and max V is approached the stress placed on the hamstrings is at its height
Thus, from a weight training perspective, far greater liberties may be taken during the GPP and early phases of a short to long program because the stresses associated with max V and speed endurance runs are not yet present and any strength gains yielded from posterior/hip/leg resistance training are likely to be realized in improved start and acceleration.
Exactly. Just received a message from one of my college athletes. They pushed the envelope in the weight room while adding longer max speed runs. 5x10 on RDLS at a fairly high percentage of their squat. Guess what happened?? After 13 hamstring pulls, this coach still hasn’t learned I guess. :mad:
This has turned into a really interesting thread, thanks for all the info James.
I really like the look of your programme in general. One thing is was wondering about though is the above quote. I understand where you are coming from in that general strength is one of the easiest qualities to develop in your athletes as a strength and conditioning coach. I believe that most football S&C coaches put far too much emphasis on it at the expenses of other elements of their programmes. However I am slightly surprised at just how little emphasis you seem to put on it.
Simply looking at it on paper I would have thought that only the most gifted athletes would develop the strength and size necessary for football without more emphasis on weight training. Obviously this is not the case as your athletes are doing tremendously well.
I would assume that the answer probably lies in the other elements of your programme such as sprinting/jumps/med ball work driving the progression of weights and allowing you to use lower volumes/intensities. Would you agree with this?
If you had a player come into your programme that was skilful but much weaker than they should be for their position, do you think a greater emphasis on strength work would be necessary, or would the way your programme normally works be sufficient to bring them up to the desired strength levels?
When I make statements regarding the ease of general strength development and how it only plays one component in the global process- this doesn’t mean that it isn’t addressed.
For those who arrive here underdeveloped in this regard I certainly make it a point to bring them up to speed. Same goes for guys that have been here and came here underdeveloped.
when I state that general strength training isn’t emphasized, my point is that I view it as just one of the many necessary variables in the process. I don’t get rah rah about it and more often than not the environment in the weight room is nothing like what we see in so many weight room videos of other collegiate programs. This is not to state that our training atmosphere is like an insurance seminar; however, our guys know that we’re not winning games in the weight room.
Agreed. Considering again that hamstring pulls are multifaceted I thought I would make some points worth noting.
It is now generally accepted that the biceps femoris acts more as a knee flexor and external rotator of the tibia.
Biceps femoris is the most commonly torn of the three hamstrings.
Deceleration of the lower limb during sprinting once the femur as reached peak hip flexion is a common source of hamstring pulls.
I believe the GHR assists in preventing hamstring pulls in these specific circumstances. But of course, progressive practice of maximal effort sprinting is king in preventing hamstring pulls during sprinting activities. As someone mentioned earlier, we have coaches trying to find gym exercises that do this and that, but without any actual full recovery sprinting within the program.
Hi everybody i need some help!One friend of mine give me Washington strength&conditioning programs but i cant understand how periodizated the training cicles.Every cicle is 4 week-low volume,basic,strength and high volume strenght!My question is if i finish 4 week high volume strength i repeated this cicle or come back in the begining and start low volume cicle?
