Reply to comment by Zephrok in Do ligaments (ACL) build up to an injury or just suddenly fail? by Toast1185

The tendons in the fingers are joined to and powered by muscles in the forearm, so grip strength can be increased by muscle training. Ligaments join bone to bone so they can't be developed through training.

ACLs do adapt! Check out Powerlifter's ACL thickness vs general population.

Very specific article looking at heavy weight lifting in very specific athletes. "All athletes in our study began training before or during their pubertal growth spurt." And not to be a complete jerk about it, but you've posted a few comments with this article, published in a journal that went out of business in 2014 and looking at 9 (NINE!) total weight lifters. I'm all for looking at new data, but this isn't it.

It would also be more useful showing the ligaments getting thicker rather than a comparison to the general population since the people that are able to lift heavier weights might be ones with thicker ligaments.

That's such a great point. Selection Bias. The ones with the thicker ligaments were able to lift heavy weight or stayed in the sport. The ones with regular ligaments either tore their ACLs or dropped out. It would be like saying that playing basketball makes you taller. Great thought. Thanks
