Important role of muscle carnosine in rowing performance.

The role of the presence of carnosine (beta-alanyl-L-histidine) in millimolar concentrations in human skeletal muscle is poorly understood. Chronic oral beta-alanine supplementation is shown to elevate muscle carnosine content and improve anaerobic exercise performance during some laboratory tests, mainly in the untrained. It remains to be determined whether carnosine loading can improve single competition-like events in elite athletes. The aims of the present study were to investigate if performance is related to the muscle carnosine content and if beta-alanine supplementation improves performance in highly-trained rowers. Eighteen Belgian elite rowers were supplemented for 7 weeks with either placebo or beta-alanine (5 g/day). Before and following supplementation, muscle carnosine content in soleus and gastrocnemius medialis was measured by proton magnetic resonance spectroscopy ((1)H-MRS) and the performance was evaluated in a 2000 m ergometer test. At baseline, there was a strong positive correlation between 100 m, 500 m, 2000 m and 6000 m speed and muscle carnosine content. After beta-alanine supplementation, the carnosine content increased by 45.3 % in soleus and 28.2 % in gastrocnemius. Following supplementation, the beta-alanine group was 4.3 s faster than the placebo group, whereas before supplementation they were 0.3 s slower (p=0.07). Muscle carnosine elevation was positively correlated to 2000 m performance enhancement (p=0.042 and r=0.498). It can be concluded that the positive correlation between baseline muscle carnosine levels and rowing performance and the positive correlation between changes in muscle carnosine and performance improvement suggest that muscle carnosine is a new determinant of rowing performance.

    Marc….ever heard of Assualt by Muscle Pharm? Besides the horrible name, it looks like it has some good things going on. What’s your take on it?

      It looks like an average product, but it’s hard to tell with the proprietary blend…it makes a HUGE difference how much of each ingredient is included which is impossible to tell. The other issue is the taurine content, which is a great supplement for post workout, or before bed due to it’s ability to relax the CNS and boost GABA levels in the brain. Too much taurine preworkout will actually limit the body’s ability to recruit high threshold motor units needed for low to moderate rep strength training. If you’re doing high rep work (12+reps per set), then it doesn’t really matter.

      Muscle Pharm is a joke anyway, use a real product like Protocol from Genomyx my good man. It’s a solid company run by great people, high quality ingredients. And cheaper than Assault. Use it at 3-4 servings per day. I love the stuff.

    I have been taking beta-alanine for about 6 weeks now and love it. I take that, creatine monohydrate, fish oil, a multivitamin and protein. That’s really it. It was recommended highly by the guys at http://www.bestpricenutrition.com

    They did a great video recommending it, which is why I bought it…
