...wheel with his whole strength. His arms stiffen, and he is as likely to steer off the road as along it. His legs are forcibly extended, and his feet are pressed down hard. It is the muscular act that Sherrington, who discovered it in the dog, named the 'extensor thrust.' . . . In so doing [the motorist] presses his foot hard down on the accelerator pedal. If then the first jump of the car sends it along a course where it meets other jolts and bumps in rapid succession, the driver tries in vain to recover the equilibrium...
...like manner those publications that reprint in extensor the naturally biased statements of publishers and producers without so much as casting a critical eye over them are guilty of furthering the designs of prejudiced prophets, it standards of taste are to be elevated to any appreciable degree, the duplicity involved in so playing about on the border-line between truth and falsehood must have...
Ruptured muscles.--These injuries were common and affected either the quadriceps extensor of the leg or the hamstring muscle. Ruptures of the quadriceps were especially common among the heavy men and in many cases were due apparently entirely to the muscular exertion of quick starting. In some cases and especially in the severer ones, the injury appeared to be due to a violent blow upon the thigh of a man running at speed with the muscles tense. Ruptures of the hamstring muscles, which are also common among sprinters, were in every case due to muscular exertion alone. These cases were...
...that this defect is the chief in causing the female to be a poor tennis player. The smallness of her ribs, thinness of the scapula, and shortness of the clavicle unite to prevent her from reaching high balls. These defects, together with the unusually large size of the triceps extensor muscle, make it hard for the female to serve successfully. Were it not for these anatomical peculiarities of the female, she would doubtless far surpass the male at tennis. She can run faster, see more quickly, and is not so easily confused. But the scientific fact remains that tennis...
Harvard men are generally strong in the legs, the extensor, flexor, and calf being as a rule well developed; and there is only about one case in ten where special exercise for the legs has been ordered. The usual weak point is the upper portion of the chest, and the neck, which in many instances is bent forward. This is generally the result of continual stooping over a desk, as many students have had little attention paid to their physical development while their bones were easily bent from their normal state. There have been no prevailing weaknesses, such as diseases...
