I have heard that also. So finally went to ask jeeves No they don't have an extra leg muscle but are more athletically inclined than caucausians. Here is part of the article ... the rest may be found at the link I have in "source". *************************** White men can't jump. Asian men can't either. But according to Jon Entine's new book, Taboo: Why Black Athletes Dominate Sports and Why We Are Afraid to Talk About It, Black men - and women - sure can. The usual reason given for Black athletic success is that Blacks have little chance to get ahead elsewhere. But Entine's new book shows that in sports, Blacks have a genetic edge. The physical facts Entine reviews are quite well known. Compared to Whites, Blacks have narrower hips which gives them a more efficient stride. They have a shorter sitting height which provides a higher center of gravity and a better balance. They have wider shoulders, less body fat, and more muscle. Their muscles include more fast twitch muscles which produce power. Blacks have from 3 to 19% more of the sex hormone testosterone than Whites or East Asians. The testosterone translates into more explosive energy. Entine points out that these physical advantages give Blacks the edge in sports like boxing, basketball, football, and sprinting. However, some of theserace differences pose a problem for Black swimmers. Heavier skeletons and smaller chest cavities limit their performance. VERY INTERESTING

There are allelic variations in functioning forms of some muscles. The plantaris muscle is frequently missing. 105/1400 legs or 7.5% in one study while another group found 6.2% of legs showed a complete lack of the leg muscle. http://www.ejbjs.org/cgi/reprint/25/4/82... These are now thought to be vestigial muscles that flexed toes for grasping, which we no longer need. There are differences in how common any version of an allele is based on the ancestral subpopulation. Certain populations acquire (or drop) a trait and it confers enough advantage to become very common in that population over time. For example in the psoas muscle group in the lumbar region of the lower back. In some populations the psoas minor muscle (PMI) is missing but the psoas major muscle (PMA) is larger in cross section. There is a shift between two smaller versions of the muscles the PMI & the PMA and one larger version with just the PMA. In some populations the small PMI is more commonly missing than in other populations. In the case of the PMI/PMA ratio there is a real difference found in the very few cadavers examined so far. There was no work in this paper to connect the cadavers to any specific regional parent population in either Asia, Europe or Africa so the predictive accuracy of this work on is rather low but indicates a possible point for a future well designed study. http://www.pubmedcentral.nih.gov/picrend... Why is this worth studying? Back pain in the lower lumbar region. The psoas stabilizes the lumbar. http://www.springerlink.com/content/3nelj6wfk1xll158/ The iliopsoas muscle complex are involved in the stability and movement at the lumbar spine, pelvis and hip. http://www.blackwell-synergy.com/doi/abs/10.1111/j.1600-0838.1995.tb00004.x Further work indicates there may also be ligament differences in the anatomy of the lumbar region. http://content.karger.com/ProdukteDB/produkte.asp?Aktion=ShowFulltext&ProduktNr=224197&Ausgabe=227414&ArtikelNr=46501 This kind of study is guided to look at patterns of use and work injury and what genetic differences ( gender or subpopulation) associate with particular kinds of injuries. The medical field has ignored very real differences in gender and ancestral populations for too long with harmful impact on how individuals are treated medically. There are differences and they need different treatment patterns.

Neo Originally Answered: Is it a myth that blac*ks have an extra muscle in their leg?
Yes, that is bull. We are all the same skeletally except for a few differences. For example, blacks and white have different shaped skulls, and men and women have different shaped pelvises. (Both of those are also methods that forensic scientists use to help identify bodies) It sounds like something a white supremist made up to help his argument sound more scientific.
Neo Originally Answered: Is it a myth that blac*ks have an extra muscle in their leg?
It is neither scientific nor is it true. I was an E.M.T. for 30 yrs & also an L.V.N. for a number of years. I never ever heard of this & certainly would have if it were true in any way.

It has to do with respect of for the lineage of the cars. America pioneered the V8 engine for use in mainstream cars. We own that segment. And we have showcased what American V8 engines can do in our muscle cars and trucks over the years. American Muscle is ALWAYS powered by V8 power. We don't rely on Turbos or Super Charger, it's good old American V8 power. And to some extent I'd even say it's Pushrod Engine V8 Power, but GM is now the only manufacturer who really uses Pushrod Engines, and look how good they still are. I mean, American cars do what European cars can do usually with 2 less cylinders.lol (exception is Porsche since they always use flat-six). And the only way the Japanese can even come close to American V8 power output is bolt on twin turbos and intercoolers. And when American manufacturers finally decide to use to new fangled gizmo's (Corvette ZR1 SuperCharger, Roush Mustang Stage 3 Super Charger) we blow EVERYONE out of the water. But we're always powered by a V8. V6 just dilutes the nameplate. I know the new V6 Camaro RS is pretty darn fast, faster than the 2002 SS if I'm not mistaken, or at least really close to it. But, it's still a V6, it doesn't have that same intensity of the rumble of a V8 Pushrod engine.

I don't think most muscle car guys mind the V6 models because they'll just get a V8 anyways and the V6 models make the V8's seem even cooler. You're right, there are lots of great performing V6 engines out there in American cars. I drove a 2006 V6 Mustang and it made enough power and torque to impress me. I guarantee that Ford has sold 10X more V6 Mustangs at least then the V8 GT or Shelby. The only criticism I have over the V6 cars is that you only live once, and if you're gonna get a Camaro or Mustang in the first place you might as well get the extra 100 horsepower and torque with a V8 and a more manly sound. Even a V6 Camaro or Mustang isn't an economy car and they only average about 2mpg better then a V8 typically. Most EFI V8's now are surprisingly economical and heck, they only displace 4.6 liters in the Mustang GT.

More cylinders=more available power, period. A motor is only able to produce as much power as the air it moves allows. To move the same amount of air a 4 cylinder has to be twice as big, or spin twice as fast as an 8 cylinder. Limitations in piston speed(limits the rpm), because of metallurgy, and head flow(limits max air flow), because of design, used to be the biggest problem. This being the case, with a maximum piston speed, and airflow, the only way to increase HP was increasing the cylinder count. While the new V-6 is an awesome motor, it would have more HP if it had another two cylinders. Thus the V-8 SS The second reason is that the old muscle car standby was to concentrate on the V-8 motors, and to throw whatever cheap V-6 was available into the base models just to sell the car to those without the means or desire fo the V-8. So what you ended up with is a heavy car meant for a high output V-8, with an anemic, low performance V-6. Think of it this way, if your Vtec 4 cylinder honda had a Vtec V-8, it would have twice the power. All these examples are based on an equal single cylinder displacement. Also assuming the same design, that 800 HP V-6 could be a 1066 HP V-8.
