Another study, presented in May at the American College of Sports Medicine, warned that wearing high heels on stairs was especially perilous. The body compensates for the instability by putting an emphasis on the knee-extensor muscle. "It's an eccentric muscle action," says Wendy Miletello, one of the authors and an assistant professor of kinesiology at Louisiana Tech, who (speaking of eccentric) wears heels. Future biomechanics studies may look even more closely at pump-related injuries and fatigue...
...first year she had a Shakespeare TF with "the best arm muscles I have ever seen. He was really hot." "Beta", a junior taking her pre-med requirements, confides that during a lab, her physiology TF "rolled up his T-shirt and started flexing and saying, 'Well, the extensor works this way and see how when I flex the bicep..."' Beta is sure that he liked being able to show the class that he was a big, buff...
...body may be affected), it can nevertheless be built up by exercising healthy muscles near by, or the corresponding set on the opposite side. Significant evidence: one subject exercised her left forearm flexor, got a 76% increase in its strength, plus a 20% boost in its antagonist extensor muscle, and an amazing 130% in the unexercised right flexor and 50% in the right extensor...
...Most strain is on the extensor muscles of the leg, least on the flexors ; for example, the rudder pedal is kicked, not pulled. Cadets are trained to lie on their backs, kick their legs in bicycle movements...
...animals, fully developed in newborn babes, unshakable by training. Now that it imperils motorcar operators, Dr. Henderson thinks it could be successfully sidetracked by installing a pedal in the shape of a wide panel almost flush with the floor boards under the driver's left foot. When the "extensor thrust" shoots both his legs out, though the right foot may jam down the accelerator, the pedal pushed by the left foot will turn off the ignition or close the carburetor intake...
