...an old Run DMC song, and also a reference to back pain.
JOSPT June '09- "Fitness, Motor competence, and Body Composition Are Weakly Associated With Adolescent Back Pain"
Here's what I get out of this article.
1. This is not the first study to find a correlation between low back pain & increased trunk flexor strength (Newcomer et al in Acta Paediactrica, '96)
2. Watch that waist line
3. I don't think you can have a healthy back without strong, powerful 3D leg strength.
4. The Sit & Reach Test is a waste of time.
5. I said this before in previous posts, but I believe that athletes in sports of a repetitive nature should spend some time in the recovery-restoration process running backwards, throwing with the opposite arm etc.
