A lot of things take many years to hit common public knowledge after they've been debunked or proven false in the scientific world.
The National Strength and Conditioning Association(NSCA) is good place to find the up to date data and scientific findings from constant case studies throughout the country. It's an educational non-profit institution and their archives go back over 50 years. I've been with them over 20 years,though I added the ISSA last year.
All of your collegiate,Olympic and professional sports strength coaches normally certify through them.
I used to have about 400 pounds of case studies that came out every quarter until my wife made me throw them out..lol.
Their nation conferences each year are second to none when it comes to strength,conditioning and the athlete,plus all of the newest high tech toys for performance.
