Trans ladies retain athletic edge after a yr of hormone remedy, examine…

A brand new examine suggests transgender ladies preserve an athletic benefit over their cisgender friends even after a yr on hormone remedy.

The outcomes, revealed final month within the British Journal of Sports Medicine, may imply the present one-year ready interval for Olympic athletes who’re transitioning is insufficient.

“For the Olympic level, the elite level, I’d say probably two years is more realistic than one year,” mentioned the examine’s lead creator, Dr. Timothy Roberts, a pediatrician and the director of the adolescent medication coaching program at Children’s Mercy Hospital in Kansas City, Missouri. “At one yr, the trans ladies on common nonetheless have a bonus over the cis ladies,” he said, referring to cisgender, or nontransgender, women.

Roberts began investigating the athletic performance of transgender men and women while in the Air Force, working under co-author and physician Lt. Col. Joshua Smalley at a clinic coordinating care for airmen beginning or continuing their gender transition.

Active duty service members are required to take a physical readiness test every six to 12 months. Roberts, Smalley and another co-author, Dr. Dale Ahrendt, realized they had access to robust data on service members before, during and after they started hormone replacement treatment.

The three physicians conducted a retrospective review of medical records and fitness tests for 29 transgender men and 46 transgender women from 2013 to 2018. The Air Force’s fitness assessment includes the number of pushups and situps performed in a minute, and the time required to run 1.5 miles.

They also had records on when the subjects started testosterone or estrogen, the type of hormone used and the number of days from when treatment began to when their hormone levels reached the normal adult range for a cisgender person.

For the first two years after starting hormones, the trans women in their review were able to do 10 percent more pushups and 6 percent more situps than their cisgender female counterparts. After two years, Roberts told NBC News, “they were fairly equivalent to the cisgender women.”

Their running times declined as well, but two years on, trans women were still 12 percent faster on the 1.5 mile-run than their cisgender peers.

Unsurprisingly, testosterone affected the fitness scores of the transgender men they reviewed: Prior to starting hormones, they performed fewer pushups and had slower running times than the cisgender men in the control group. A year into treatment, though, those differences disappeared.

With situps, the trans men were comparable to the cisgender men before treatment and actually exceeded them after a year on testosterone.

The longest any participant was followed was two and a half years, according to Roberts.

He said he’s not suggesting being in the military is the same as being an elite athlete, but, he added, “it’s a comparable situation, where you have someone doing whatever they can to maintain or improve their abilities.”
