GoSwim GoldBody depth in water chart
Start New Topic|
Well here is a fairly accurate chart to see how your body weight/height ratio affects how high your body rides on the water during freestyle and backstroke swimming. It isn't a method to know exactly how deep your body sinks into the water while swimming, but a method of comparison. Check out how the top swimmers match up with yourself it's pretty interesting. It is based on simple buoyancy principles. Notably water temperature has a neglegible affect on how buoyant your body is in the water unless you go swim in waters at boiling temp or freezing, but then you have other concerns!

for example phelps is around 6.15in depth in water on this chart with his 6ft4in = 6.333ft and 200lb wikipedia info. Compared to my 6ft and 200lb giving me something around 6.4in depth. So I would expect to be about 1/4in deeper in water than phelps during freestyle or backstroke swimming... Back when I was 225lb though! I could expect to be 7.5in deep! making me about 1.35in deeper than someone like phelps!! Good thing I am healthier nowdays! I hope this helps people to better understand what body weight and height does to your swimming! |

Bah. Thinking about it body fat probably helps a person float more than harming. So this table would only be accurate to compare without taking into account body fat.... Which is in fact significant... |

Boy fiZZle...now it sounds like rocket science! |

There is a proffessor here in Groningen that studyed the swimtechs of wateranimals...incl. birds ....and compared them with the swimmingsport.....also very interresting....like to breathe out at start just before you hit the water like some birds do!!!...tried it....and it really works.... |

What is it doing when you breathe out before hitting the water. Unfortunately I am not 100% sure how to take into account the buoyancy caused by body fat or I could modify the equation on the chart to take it into account. The only difference is that you'd need to input your bodyfat percentage somehow hmmm. |

If you have less air in your longues your volumeweight reduces....it's like your shoot trough the water.....just try it!!!!! |
|
|
how do you dive long(er) with you lungs empty(ier)?! |
|
|
Your going faster trough the water....and the lungs must be emptier....hihihi...Some waterbirds do this as they enter the water when they dive......hope you try it and keep me posted....WORKS FOR ME!!!!! |
