Is this stuff that they expect on the ACSM exam? Seriously...when are you going to be calculating % grade to determine appropriate VO2 Max? First, you have to know what a person's VO2 Max is to make a true accurate calculation. Otherwise you're just making an educated guess. Are you going to send all of your clients to get a VO2 Max test at the local university?

This is absolute nonsense - especially for folks without an exercise science degree. Heck, I have a master's in kinesiology and almost a second master's in biomechanics and I probably learned some of that stuff, but don't recall much of it. And, truthfully, it's not practical.

This is the problem with the fact that Ph.D's are writing these certifications. They have such a disconnect with the real world. I like to call them "Educated Idiots" because that's what they are. They only know research and reality as it pertains to laboratory conditions.

How about teaching people about some real life stuff like functional anatomy. Tell me, Jeff, does that ACSM book explain how important glute max strength is to prevention of knee injuries in females because the glute max is important in controlling femoral internal rotation? Does it tell you anything about how most people have poor control over their scapulae and this may be critical in shoulder dysfunction, particularly subacromial impingement? Does it discuss anything about interval training and the evidence that it is most effective in fat loss (assuming the client can handle such training)?

What about proper bench press technique? Does it say a single word about retracting the scapulae to create more space between the humeral head and acromion process of the scapula since the scapulae are pinned between your body and the bench and cannot move as they normally would when the shoulder girdle protracts as in a bench press? Does it mention the words "scapulohumeral rhythm?"

No, it offers nothing that is really pertinent to personal training because the people authoring these certifications are morons. If you want a real education, you have to get it on your own. The people who should be creating certifications are folks who operate in the field - top strength coaches and trainers...that's why college strength and conditioning coaches now have their own cert - CSCCA and it's recognized above the CSCS because it actually requires a mentorship with a coach who has mentor-status.

Anyway, I just had to get that off of my chest because this information is so trivial and impractical. And, here you are being forced to completely stress out about something that you'll probably never ever use, realistically-speaking. If you want to monitor someone - heart rate works so much better and it's so much easier to get an indicator of how hard someone is working and to monitor rest intervals, etc. using a heart rate monitor that you can buy from the local sporting goods store.

Well, I'll get off of my soapbox now I hope I have not offended anyone.

Chris, I could not agree more. When I get some time I am going to start a new thread asking other trainers what they had to learn to pass their cpt exam vs. what they really use when training.

hey jeff yeah whenever ur ready sort wat u need to sort out

the workshop will benefit u alot, ur prob get hand cramp from the amount of notes u write

they also do sum practical with u with skin folds and other stuff hope u enjoy it

This is one of the issues with ACSM - its not real life for most personal trainers. Trust me, 99% of personal trainers will NEVER do metabolic calculations. Probalby at most youll be doing MET to VO2 conversions but thats about it

Here is the thing to consider before you consider ACSM - think about the populations you want to work with. If you want to work in a hospital fitness center, cardiac rehab or with special populations a lot, then ACSM would be good and you may find yourself doing metabolic calculations. If you are the rest of us you probably wont need to know it.

In my former life I was the wellness director at a hospital -based fitness center. It was ranked among the top 100 of all clubs in the USA. Even there I never did any metabolic calculations.

I hope this helps

Can someone help me by explaining the answer to following question that comes from David Swain’s Exercise Prescription book, second edition, page 164, question #8. I need the step by step process of solving this question in layman’s terminology explained to me.

8. For indoor exercise aerobic exercise, Marina would like to walk on a treadmill. If she walks at 3.5 mph, what % grade would allow her to exercise at 70% of VO2R?

The book gives the following hint (or equation) to solve the question on page 186 and says the answer is a 10% grade.

[Calculate speed in m . min-1 as mph x 26.8; solve for grade in the following equation:VO2 during walking = 3.5 + 0.1(speed) + 1.8(speed)(fractional grade).]

I am very frustrated because here they are telling how to solve the equation, and I am still not getting it right. I thought I had a basic understanding of algebra but apparently I am doing something very wrong.

Could someone please show me the step by step process on how you arrive at the answer of 10%.

this question needs more data
means value of VO2R
through which u can calculate 70% of VO2R
