（2020·西城区·北京师大附中高一期末）Running on Empty
宽带连接怎么设置For almost a century, scientists have assumed, tiredness—or exhaustion—in athletes originates(起源于) in the muscles. Preci explanations have varied, but all have been ba
d on the “Limitations Theory”. In other words, muscles tire becau they hit a physical limit: they either run out of fuel or oxygen or they drown in harmful by-products(副产品).
In the past few years, however, Timothy Noakes from the University of Cape Town, South Africa, has examined this standard theory. Tiredness, he argues, is caud not by signals springing from overtaxed muscles, but is an emotional respon which begins in the brain. The fundamental nature of his new theory is that the brain paces the muscles to keep them well back from the edge of exhaustion. When the brain decides it’s time to quit, it creates unbearable muscle tiredness. This “Central Governor” theory remains controversial, but it does explain many puzzling aspects of athletic performance.
A recent discovery that Noakes calls the “lactic acid paradox” made him start rearching this area riously. Lactic acid is a by-product of exerci, and the increa of it is often mentioned as a cau of tiredness. But when rearch subjects exerci in certain conditions created artificially, they become tired even though lactic acid levels remain low. Nor has the oxygen content of their blood fallen too low for them to keep going. Obviously,
something el was making them tire before they hit either of the physiological limits.
Noakes conducted an experiment with ven cyclists. It has long been known that during exerci, the body never us 100% of the available muscle fibres(纤维). The amount ud varies, but in some tasks such as this cycling test the body calls on about 30%. His team found that as tiredness t in, the electrical activity in cyclist’s legs declined—even when they were making a great effort to cycle as fast as they could.
