SHAVE OFF SECONDS

While some of us may be partial to the odd bit of manscaping, many professional athletes have come to treat body shaving as a competitive sport. And a hairless torso doesn’t just emphasize those finely tuned muscles, it has many technical advantages too. We’ve separated the posers from the professionals to find out which sports really require a follicle-free physique (and who just likes the feeling of being silky smooth).

CYCLING

Contrary to popular belief – or the insistence of professional cyclists – shaving your legs doesn’t have anything to do with aerodynamics. In fact, there are no academic studies to show that a bald limb will slice through air any better than a hairy one. The resistance is simply too minimal to matter and, if professional cyclists say otherwise, then it’s simply the placebo effect of feeling and looking like they’re a hardened sportsman (see lurid-coloured lycra, fancy gadgets, having your lunchbox on display etc). That extra mile is all in the mind, after all.

The only genuine reason for body shaving is to reduce road rash, those unfortunate (and sometimes rather gory) moments when a cyclist crashes and has to pick out all manner of grit from their wounds. Having a hairy leg does not make this easy, nor does it make the removal of plasters any less painful.

SWIMMING

Before hightech suits were authorised, swimmers had a very good reason to shear their chests smooth due to something called ‘laminar flow’, the ease with which fluid can pass around an object. Water is 1,000 times more dense than air and therefore requires a perfectly smooth surface to cut through it.

Scientific studies have shown that removing body hair dramatically optimizes laminar flow. It can have a great impact on the distance achieved with each stroke and, in an Olympic race, that 100th of a second can make all the difference!

السباحة

قبل اعتماد استخدام ملابس السباحة عالية التقنية، وجد السباحون سبباً وجيهاً لحلاقة شعر الصدر بسبب ما يسمى "الانسياب الصفحي"، وهو مدى سهولة تدفق السائل حول الجسم. يعتبر الماء أكثر كثافة من الهواء بمقدار 1000 مرة، ولهذا يتطلب سطحاً ناعماً جداً ليتمكن من اختراقه.

أثبتت الأبحاث العلمية أن إزالة شعر الجسم تزيد الانسياب الصفحي بدرجة كبيرة، وقد يكون لها تأثير هائل على المسافة التي يقطعها السباح مع كل ضربة ذراع، وقد تشكل فترة واحد على مائة من الثانية في المسابقات الأوليمبية فارقاً كبيراً!

BODYBUILDING

Bodybuilders don’t receive any performance benefits from a thorough shaving; they simply have a very ‘unique’ understanding of aesthetics. Put simply, less hair makes definition more visible. And, as far as these athletes are concerned, every detail counts. Besides, what’s the use of having a washboard stomach if nobody can see it underneath a sweater of hair?
