In the classic boxing film Rocky starring Slyvester Stallone, his trainer Micky warns Rocky of the dangers of fooling around before a fight because “women weaken legs.”

But is this just a load of sporting superstition or is it actually rooted in fact?

In this edition of Sport Science, John Brenkus and the crew are determined to get to the bottom of this and find out if pre-fight sex is detrimental or even beneficial to an athlete’s performance on fight night.

But in this experiment they’re going to find out the effects on a female athlete and stepping into the lab to take off the gloves and everything else is US pro boxer Liz Parr.

 “Everything I heard I believed because anything that can hurt your performance you just want to stay away from.”

So to test this out Sport Science will measure the maximum power of one of Liz’s punches, her anaerobic endurance, her hand speed on a crash test dummy as well as testing her blood.

Once this is all said and done Liz would then have to have sex with her husband and boxing trainer Yas Parr and then come back to the lab the next day and re-do all of the tests.

How will they rate her performance, find out below.

Sport Science is an ongoing television series that explores the science and engineering underlying athletic endeavors that was broadcast on FSN and ESPN.

Each episode on series one focused on testing certain aspects of athletics (such as human flight and reaction time), while series two either poses more questions from previous episodes, or tries to re-analyze sporting moments, pitting humans against animals or machines, and even checking against other sports or challenging the odds with data. Professional athletes are featured prominently and are used to test the limits of the human body. [source : wiki]
