TESTOSTERONE MAY INCREASE KNEE LIGAMENT STRENGTH "Testosterone May Increase Rat Anterior Cruciate Ligament Strength" Study from John Hopkins (W.A Romani, S.M Belkoff, J.H. Elisseeff), July 2016 1
BACKGROUND Women are more likely than men to injure the anterior cruciate ligament (ACL). This study examined the role of testosterone.
2
STUDY TESTED ACL STRENGTH IN MICE Mice with higher levels of testosterone were found to have stronger ACL's
3
STUDY RESULTS 15% MORE FORCE NEEDED TO INJURY LIGAMENTS OF MICE WITH HIGHER LEVELS OF TESTOSTERONE
Researchers found it took 34.5 newtons to tear the ACL's of mice with normal levels of testosterone. While it took 29.2 newtons to tear the ACL's of mice with lower levels of testosterones 4
APPLICATION Study author Jennifer Elisseeff, Ph.D. at the Johns Hopkins University, says the new finding could eventually lead to techniques that assess levels of hormones to identify athletes at higher risk for ACL injury, who may benefit from training strategies to strengthen the ligament.
