+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.
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 %
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.
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.
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%.
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.
Finally a video of someone who doesn't have 5% body fat. This is more my body type and it's easier for me to figure out how to do it.

Travis Erickson ya right, colt was shredded
I used this to study for my skinfold practical. Thank you for making this, it was a tremendous help.
+Ty Martin No problem, Ty!
I am from India and I took physical education as optional subject ..your vedio helped me a lot ..thank u 😊🤗
Perfect! Thank you very much. Best video on using body fat calipers I've seen.
Great Video!!!! Also, my dude is looking buff!
Thanks
This has been such a great help, Thank you! But how did you go from exercise to dungeon goblin role play?
Haha! Natural transition, I guess!
Thanks for this, really well explained.
+Science James Thanks -- glad you found it helpful.
Great video. Very informative.
Very helpful for professionals
Best video to understand nd learn how to take measurements

@@TravisErickson5 if you look at cell C7, you'll see you pointed to cell B7 instead of B4.

Very informative and useful demonstration.
Thank you.
fantastic video thank you
You're welcome.
Travis Erickson, UA-cam star. Nice video, posted it for my class.
Haha! Hope it helps your students.
Thank you for the video!
Thank you so much for your info.... much appreciated : )
+Gu Amancio You're welcome!
Hi Travis, are able to know the subjects body mass %?

It looks to me that those calapers can be celebrated at the plastic where it comes in contact with our skin.

Wat is the normal values of it
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%.
I am asking four skinfold range
And I need a help from u
I want fat analysing assessment chat with normal range
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!

So what % BF for this guy? his body muscle/frame looks similar to me but I am smaller.
15% +-
