The best data is from military recruits, and there are a couple of recent studies, one published in 2020 and one in 2023. They looked at cis men, cis women, trans man and trans women. How many steps you can do in a minute, how many push ups you can do in a minute, and how fast you can run 1.5 miles. And what they found in that study was that trans women remained faster for up to two years after the initiation of gender affirming hormone therapy. At four years, trans women continued to do more sit ups and push ups.
