Turnover time - citations

[Erik Eriksson 190950]

Hi!

I'm writing a short article for my dance students about basic strength training and the necessity of slow and consistent progression.

Coach Sommers writes:

A Word of Caution

The metabolic rate of connective tissue (tendons and ligaments) is approximately 1/10th that of muscular tissue. This means that connective tissue improves it's strength and flexibility at 1/10th the speed of muscular tissue; and that it also heals TEN times slower. For example, when comparing a slight muscular pull that would require 3 days to heal to a slight connective tissue pull of the same magnitude, the slight connective tissue pull would require 30 days to heal. Yes, that is correct - a full 30 days. This is not to imply that the joint will be disfunctional for the entire 30 day period, but that it will require that period of time to regain 100% functionality and stability.

Is there any official source, (apart from Coach Sommers) that I can cite in regards to these time frames?
