Ski Racers & Back Problems

post #1 of 6
Thread Starter 
In a Sport Agility workshop, the presenter was talking about
some of the teenage ski racers he trains. Apparently, they are exp eriencig
some severe back problems from holding the aero dynamic position
of the tuck.

He has them doing specific exercses that emphasize elongating the spine
the opposite of what they do when racing.

So, if the repetitive movements of a sport
create an injury, sometimes working the muscles
in the opposite direction is useful.
Will elaborate when I get back. Key board from Hell!

In an earlier thread you mentioned the need for warm-up vs. overstretching. One gets the muscles ready, while the other loosens the tendons(?) possibly leading to injury.

When you tell us about the back, could you relate it to this?

Are there any "non-pros" there? Do civilians like me attend these things? Sounds great!

I don't get it-when you're in a tuck, your spine is elongated. When you're standing upright its more compressed.

but when you're upright (erector spinae are extended), you're in a more "natural," relaxed position. holding a tuck puts those muscles in a position they aren't used to, producing fatigue, lactic acid buildup, soreness.
most people do ignore the lower back in their exercise routines.

anyway, my take on it.

Okay. The stretching thing. I will talk more about that in the Agility thread. Although overstretching can effect the biomechanics of the back and cause problems, that's not what they were talking about, although it can certainly apply.

In a racers tuck, the spine is in a flexed position. This requires an active use of the rectus abdominus, the outer layer of abdominal muscle.

I've mentioned in many threads that the rectus abdominus was never meant to be used as an endurance oriented muscle. Unfortunately, too many things nowadays involve a flexed spine. We sit at computers, and we go to the gym, we do what?

Crunches. More flexion!

So we've trained our rectus to become endurance muscles... But there's a problem. They do not have the support network of the deeper abdominal muscles, and are thus unqualified for the job!

It is in the the upright position that are transverse abs are active. The transverse, as you all know, does in fact work with other stabilizers such as internal obliques, pelvic floor, multifidus, etc. These are the muscles that are in fact supposed to be used as endurance muscles.

As I mentioned in one of the "knee" threads, many injuries happen not because of poor technique or a specific accident. Sometimes, they occur simply because a person spends alot of time in a position that may be functional to their sport, but non functional to daily activity.

So if you take a high school ski racer who is also spending a deal of time at a computer, at a desk that isn't exactly ergononmic, you end up with a kid who spends way too much time in flexion, resulting in a back problem that was not caused by any heroic maneuvers on the slopes!

Does this mean that ski racing is bad? ABSOLUTELY NOT!!!!

But it is causing conditioning coaches to take a serious look at how they've been training athletes.
Throughout this conference, the sports oriented presenters were putting major emphasis on the extenion phase of abdominal work. It is then that the muscles are decelerating, eccentrically.

Much research is being done about the use of eccentric deceleration as a means of improving sports performance, as well as prevent injuries.
