Ephedra and Caffeine: No Good for Strength? The Effect of Ephedra and Caffeine on Maximal Strength and Power in Resistance-Trained Athletes Journal of Strength and Conditioning Research:Volume 22(2)March 2008pp 464-470 Caffeine and ephedrine-related alkaloids recently have been removed from International Olympic Committee banned substances lists, whereas ephedrine itself is now permissible at urinary concentrations less than 10 μg·mL-1. The changes to the list may contribute to an increased use of caffeine and ephedra as ergogenic aids by athletes. Consequently, we sought to investigate the effects of ingesting caffeine (C) or a combination of ephedra and caffeine (C + E) on muscular strength and anaerobic power using a double-blind, crossover design. Forty-five minutes after ingesting a glucose placebo (P: 300 mg), C (300 mg) or C + E (300 mg + 60 mg), 9 resistance-trained male participants were tested for maximal strength by bench press [BP; 1 repetition maximum (1RM)] and latissimus dorsi pull down (LP; 1RM). Subjects also performed repeated repetitions at 80% of 1RM on both BP and LP until exhaustion. After this test, subjects underwent a 30-second Wingate test to determine peak anaerobic cycling power, mean power, and fatigue index. Although subjects reported increased alertness and enhanced mood after supplementation with caffeine and ephedra, there were no significant differences between any of the treatments in muscle strength, muscle endurance, or peak anaerobic power. Our results do not support the contention that supplementation with ephedra or caffeine will enhance either muscle strength or anaerobic exercise performance. This was an interesting piece of information. I'm not sure how many of you have ever played around with pre-workout stimulants, but if you've ever been a fan of ephedra/ephedrine products, you'll know how they have a very strong effect on alertness and energy....which is a good thing if you're in need of some extra training intensity. Also, ephedra alkaloids (ie, the herbal form of the Ma Huang plant from which we get ephedra, not to be confused with ephedrine HCL which is a purified form) have recently been removed from the IOC banned list...which is an interesting move in itself.

I've been traveling around a bit lately, so it's been sparse on the updates as you can see. I'll try to keep things more updated, but you see how far my promises go. With that in mind, there's a new-ish blog that I'd highly suggest you pay attention to if you're interested in strength & conditioning. No gimmicks, no sales pitches, no Inner Circle -- just good, solid information from a real strength coach training real athletes. You can have a look here: http://willheffernan.blogspot.com Will's in Ireland, so you know what that means: he's drunk most of the day. Which is what lets him update his blog around 50 times per day. Go have a look. |

An Open Letter to the IOC and WADA 5 April 2008
An Open Letter to all members of the International Olympic Committee and all members of the World Anti-Doping Association:
I am greatly saddened by the recent news regarding the Greek weightlifting team and the positive drug tests from some of their number. This egregious violation is simply the latest in a long stream of constant dishonesty from the coaches and athletes of the world.
I want to commend the IOC and WADA for their efforts in screening out these unethical participants, those that choose to gain an unfair advantage over their competition.
However, I cannot help but feel that there is simply not enough being done to combat this problem. And make no mistake, this is a serious problem indeed!

Borrowing or Theft? Where's the line? |

Borrowing or Theft? Where's the line? In copyright law, there's a concept known as "Fair Use". The US Copyright Act (which can be found online at www.copyright.gov) states "purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright." There are also other mitigating factors that are examined on a case by case basis.
So, using material for "reasonable purposes" is not against the law. What I'm doing here, criticizing and satirizing other copyrighted materials found on the Internet, is not a violation of copyright law. It falls under Fair Use.
Those of us that put ourselves out there as "experts" on the subject matter have an interesting dilemma. On the one hand, we benefit immensely from the free exchange of ideas. Most everything I know on exercise science has come from talking shop with people like me -- guys and gals that enjoy the topic and like to hash it out. Not unlike any other hobby, really.

I just did an interview with Leigh Peele, who runs the Fat Loss Troubleshooter over at Avidity Fitness . You can read it here . I talk a little shop about the hows and whys of hatin' on Gurus, and give a little bit of outlook on the whole training process. Leigh's an all-around cool chick and a fellow Southerner. So go have a look. Or else. |

So, if you managed to sit through this, I give you props. My hosting company is having "problems with the SQL database, which they hope to resolve soon." I don't know about you, but reading sites that load up faster than a 14.4 kbps modem c. 1996 is pretty damn annoying. So they've got a few more days before I pull the plug and go elsewhere. I haven't forgotten my three faithful readers. Also, the first draft of the book is DONE. Working on edits now, and keeping fingers crossed it will be ready to go by the end of April. Stay tuned. |

Are you result-based or idea-based?
One of the core problems facing everyone involved in fitness and strength training is how to figure out what is garbage and what is legitimately effective.
This can be difficult because the entire field of exercise science is still made up of a lot of unknowns. Most of the knowledge and things we take for granted today have come in large part from experts in the field, the coaches and trainers that actually work with various athletes.
Even then, there's a wide disagreement among these practitioners. A lot of it will really boil down to argument over fine details, as the general philosophies will usually line up.
But the devil can often be in the details; how do you know what you should listen to and what you shouldn't?

Functional or Not? What does the word “functional” mean to you? If you've had any sampling of the modern fitness industry, “functional” will probably mean doing exercises that have a high carryover to the motions and actions found in most team sports. It could just as easily mean standing on a wobble board doing one-handed dumbbell presses, in order to improve “core stability”. Have you ever stopped to think what “functional” really means, though?

If You Don't Know What You're Talking About........then please stop talking. Stop giving advice. Most of all, acting like you're suddenly God's gift to exercise form just because you passed a piss-easy certification.

I Am Not Serious Because...Are you serious about getting in shape? Are you serious about training your clients, or coaching your team? Awesome. What about the people that are Not Serious? Apparently, that is what happens when you don't feel the need to shell out $49.99 (for the next 10 minutes!) for every latest Guru scam-tactic. The logic here is that any trainer or coach worth his or her salt would be head over heels about learning new things. This is true.
