What is the difference between Flexibility and Mobility?
I’ve always used the Bill Hartman definitions; they go something like this:
Mobility – Range of motion under specific circumstances (specific)
Flexibility – Range of motion about a joint (non-specific)
So mobility is specific to a certain movement – i.e. you need a certain amount of hip mobility to squat, lunge, etc.
In contrast, flexibility is non-specific – i.e. you lay someone on their back and stretch their hamstrings. This gives you an idea of their flexibility, but it’s not specific. Just because they have great hamstring length doesn’t mean they’ll be able to perform functional movements properly or without compensation.
From a study published in the Swimming Science Bulletin. Authored by Brent S. Rushall & John Marsden:
"All sports require high degree of skill for superior performance. The major emphasis of a (youth athletic) training program should be skill excellence. For skills to be developed, learning should occur in non-fatigued states… It is advisable to schedule auxiliary training sessions either after a (sport) session or at some time that allows complete recovery from its execution so that no residual fatigue is carried over".
I’ve never mentioned this in literature, but have advocated it several times through lectures and seminars. Learning how to create appropriate training sessions is crucial to working with young athletes. If you are forced to have the technical practice AND the training session within the same day (as is typical), make sure that the training session comes AFTER practice. This keeps the body and CNS rested and for skill acquisition and demonstration during practice.
Ever notice that the "science" of strength, conditioning and fitness is more
complex than many realize?
Train Young Athletes
It’s really got nothing to do with just throwing some exercises together and
counting sets and reps.
Does speed training come before or after strength training?
When is it best to train the "core"?
Where does flexibility training fit into the daily picture?
Getting the most from your young athletes and truly making them the very
best they possibly can be means knowing as much as you can about how
to train them properly.
It’s not a day-by-day concept or fly-by-the-seat-of-your-pants situation.
It requires a system.
A complete and comprehensive system that is internationally proven to be
successful and can be implemented by you TOMORROW with ease.
