+TheAndersDanilet Yes; although our subject here (and in the female video linked to above) are still pretty lean -- but approximate an *active* college-aged individual.
amazing video Mr Erickson. Would it be possible to know the measured numbers as reference? I noticed: tricep: 13mm chest: 5mm abdominal: 17mm And how much body fat the individual approximately had? I approximate 15% All the best!
I don't believe I have the exact numbers anymore (that was many years ago -- primarily made for purposes of the video). However, in the description of the video is a link to a spreadsheet (you can make a copy of it) which will apply the Brozek and Siri density-to-% body fat equations based upon different measurements.
Thanks for this video! Pointing out one error on your spreadsheet though: The formula for calculated density on Men Site B is wrong. It needs to multiple by age on the last chunk of the formula.
You may be confusing the equations; age is factored into the density calculation. As such, it's not also required in the body fat calculation. If you look closely at the formulas in the spreadsheet, you'll see that age (the value in B4 in the spreadsheet) is multiplied at the end of each of the density calculations.
@@tacoyaky8872 This is the formula in C7: =1.1125025-0.0013125*B7+0.0000055*B7^2-0.000244*B4 Try downloading another copy -- perhaps you accidentally edited the one you initially downloaded?
Great video!! The best explanation. I just have one question, in the spreadsheet, there are different results. the sum of 7, 3 site A, 3 site B, etc. Which one of those is the body fat percetage%?? Anyone who knows the answer please let me know. I will be grateful
Not exactly sure what spreadsheet you are talking about... but generally you put the sum of skin folds into a calculation which also includes their age, gender and weight to work out the %
Travis, I noticed all measurements were on the right side of the subject, does it matter if the subject is left side dominant? Also, should men do a waist measurement?
In the United States, the formulas were validated for the right side of the body. In reality, you're not going to see any big difference either way, however. Waist circumferences are appropriate for both men and women as this measurement can be a risk factor for heart disease, diabetes, and some forms of cancer.
In addition to ensuring a caliper reads zero when shut/closed, they can also be calibrated (or checked for accuracy) by having them measure a known length. This video doesn't address that element, but rather focuses on identifying proper measurement sites and taking as precise measurements as possible.
There are no specific standards, but, in general, for men: athletes are between 6-13%, fitness enthusiasts are 14-17%, "acceptable" is 18-25% and at risk is >25%.
