Dr Fond of Beetles on why train harder is not an option.
The performance gap between male and female athletes is utterly astounding; it’s not a “gap”, it’s the Grand Canyon. ...
Testosterone, the androgen driving male physical development, is a wonderful hormone. It is responsible for advantageous skeletal features that develop during male puberty, such as increased height, increased bone size and density, longer limbs, wider hand spans and a narrower pelvis, all of which make a 100m sprint or a slam dunk far easier. It also directs hugely increased muscle building capacity, allowing higher absolute masses to be achieved in shorter training times, mass which, by the way, contains a higher proportion of fast twitch fibres (responsible for explosive power) than observed in female muscles. To support this superior physicality, males have greater lung capacity, a higher VO2 max (the amount of oxygen consumed during high intensity exercise), a bigger heart with faster stroke rate and higher levels of haemoglobin, and thus can oxygenate their muscles more efficiently.
Analysis of adult/senior female sporting performances demonstrate parity with males around the age of 15 years old for individual events, and perhaps younger in team sports (22). It’s no surprise that adult female athletes are outrun, outjumped, out thrown and outlifted when males get that all-important surge of testosterone that will propel their development into superior athletes. Testosterone-driven puberty has delivered us athletes like Usain Bolt, Sébastien Chabal and Anthony Joshua. As the original anabolic steroid (prior to steroids, performance enhancing drugs were stimulant or analgesic in nature), and used widely in the 1980s in state-led doping programmes, it has almost certainly delivered us a fair few elite females too.
