To measure the angle subtended by your sidesplit! (the angle between your legs):
EQUIPMENT
-a measuring tape of some description
-a calculator that can cope with sin, cos and tan (trigonometry)
(no maths skill required)
METHOD
a) Lower yourself into the splits, and measure (use centimetres)
i) - the distance between your heels (overestimate this a tiny amount) CALL THIS "D"
ii) - the height of the triangle between the floor and your legs (overestimate this a tiny amount too) CALL THIS "H"
The overestimation is to take into account that you wont be forming a perfect triangle.
b) Rise from the splits and measure the height from the floor to your groin (as in part ii), and overestimating by a couple of centimetres again) CALL THIS "L" (it is the length of your leg)
c) There are 4 ways to determine the angle. I will explain the two most reliable ones here:
ARCCOSINE METHOD (use calculator)
~Divide H by L
~find cos^-1 of that
~multiply by two
ARCTANGENT METHOD (use calculator)
~Divide D by H
~Divide that by two
~find tan^-1 of that
~multiply by two
You will get a slightly different answer each time, because of your measuring accuracy, but they will probably be within a few degrees, eg 123 and 126 degrees.
Hope this helps some people
