The Biomechanics Of Usain Bolt

The Biomechanics Of Usain Bolt
Jamaican sprinter Usain Bolt holds the World and Olympic records for the fastest time in the 100-meter sprint. Bolt's stride, strength, and muscle coordination make him not just a biomechanical marvel, but also a gold medal favorite at the 2012 Summer Olympics. "Science of the Summer Olympics: Engineering In Sports" is a 10-part video series produced in partnership with NBC Learn. Provided by the National Science Foundation & NBC Learn

Comparing Vastly Different Body Types of Olympic Athletes New York-based photographer Howard Schatz captures the diverse range of body types of Olympic athletes. Referring to a body as an athletic build is often thought to be a perfect, rippling mass of muscle boasting a six pack, but Schatz's series reveals the wide variety of heights, widths, body shapes, and muscle mass that make up the physiques of champion athletes across an array of Olympic sports. Tall, short, heavy and light, Schatz's series clearly displays the broad spectrum of sizes and shapes that these disciplined jocks come in. Dependent on their field of athletics, their bodies are in peak condition, despite looking so different from one another. While long-distance running athletes are typically lean, this physical feature is undesirable for a weightlifter or wrestler who relies on more muscle and weight to win their respective titles.

The Anaerobic Glycolytic System (fast glycolysis) — PT Direct Glycolysis simply means the breakdown (lysis) of glucose and consists of a series of chemical reactions that are controlled by enzymes. Think of the anaerobic glycolytic system as the V6 car engine opposed to the V8 of the ATP-PC system, or the huge diesel engine of the aerobic system. The anaerobic glycolytic system produces a lot of power, but not quite as much or as quickly as the ATP-PC system. However it has larger fuel supplies (a bigger fuel tank) and doesn’t burn all its fuel as quickly as the ATP-PC system, so it doesn't fatigue as quickly as the ATP-PC system..

What does it mean to have an athletic body? Autumn over at The Beheld wrote a post yesterday entitled “On Athletic Bodies,” and I found it very thought-provoking. Here’s the meat of her post (although I think you should read the whole thing anyway, and in fact, you should probably just go ahead and put her blog into your RSS reader while you’re at it): So the first time I saw “athletic body” in the “dress your figure” pages of a women’s magazine, I got excited. Finally, someone was acknowledging that not all women who work out are doing so to lose weight—and, hey, maybe I’d finally, once and for all, learn what kind of figure I actually had. But when the advice focused on “creating curves,” I was confused: I’m not particularly busty, but lacking curves has never been my problem. In fact, since muscles generally are not shaped like squares but instead are gently sloping, I probably have more curves than I did before I started lifting weights.All the arguments I’ve made before about “dressing for your figure” apply to “athletic.”

How does Usain Bolt run so fast? Usain Bolt showed his dominance of men's sprinting at the athletics World Championship in Beijing this week with wins in the 100m and 200m. What's his secret? Is the way to win at sprinting to move your legs faster than your rivals do? Since the Beijing Olympics in 2008 Bolt has won every race he's entered at a World Championship or the Olympics, with the exception of one, where he was disqualified for making a false start.

Respiratory System by Ben Leonard on Prezi Don't believe the hype, teens are drinking less than they used to Ask your friends and colleagues about young Australians and alcohol and I bet they’ll say something about a generation out of control or a binge-drinking epidemic. The media regularly brings the worst outcomes of young people’s drinking to our attention and points to a problematic drinking culture supposedly unique to young Australians. Little wonder people believe things have never been so bad. The reality is startlingly different. Data recently released by the Australian Bureau of Statistics shows alcohol consumption in Australia has reached its lowest point since the early 1960s, having declined steadily since the mid-2000s. Survey data suggests this decline has been driven almost entirely by reductions in youth drinking.
