When I ran this by Dr. Roberts, he sounded skeptical. "If the short is compressing enough to prevent pooling of blood, will it not also prevent blood flow from below?" he asks. "Would this flow obstruction not lead to calf fatigue and loss of lower muscle function?"
No matter whether they really "fight fatigue," it's no surprise that compression shorts are eating into the jock's market share. The shorts are both more comfortable—I always thought jocks were a pain in the butt—and a lot less embarrassing-looking.
But Bike thinks there's snap in the old supporter yet. The company is launching a line with new fabrics and designs that they say will hit stores next year. They're also set to debut the "Boxer Jock" and the "Brief Jock"—products with the support of a jock without the outdated appearance. After all, the Bike athletic supporter hadn't changed in 30 years—right around the time I started wearing one. Nowadays, I just wear briefs to the gym. All the other stuff is just too much of a stretch.
