Okay....hmm...I feel the need to respond since I'm a physical therapist and I do have my CSCS.
You know what, I agree with what Rip is saying. Having a CSCS certification doesn't make you a badass in the strength and conditioning field. I wanted to get the certification to work more with the wellness aspect of physical fitness. Instead what I got was a better rehashing of my ex phys classes from PT school. What I really got was, I was able to treat injured clients better and get them to transition to sports specific activities. NOT so much information on enhancing performance of WELL clients.
I went to the NSCA convention in Vegas and I was surprised to find a lot of the speakers covering topics more in the realm of sports medicine (and corrective exercises) or exercising special populations like Multiple sclerosis. Some of the topics dealt with nutrition. I feel like the NSCA is strongly influenced by the medical field.
From that standpoint, there's a shift in the rehab field. People are being discharged from care sooner and sooner because of insurance companies cutting back on reimbursement. People can't afford to pay a physical therapist for an out of pocket visit, so they see a personal trainer...for better or worse.
So in a sense, the NSCA is responding to the demand of the population. They are preparing trainers to see more injured clients. Fatass clients. Clients with lots of comorbidities. That's what the population is, if you really look around. Are you enhancing their strength? Are you enhancing their conditioning? I would argue yes.
I agree with Vedic in that certifications...when it comes down to it, certs are absolute bullshit, especially if you don't work hard at improving your knowledge base. You don't need a certification if you have the passion and drive to learn something and apply it. Certification is really more for marketing. It just makes your client feel comfortable that you have a certain knowledge base.
