Many athletic achievements of recent date have been won by vegetarians both in this country and abroad. The following successes are noteworthy:--Walking: Karl Mann, Dresden to Berlin, Championship of Germany; George Allen, Land's End to John-o'-Groats. Running: E. R. Voigt, Olympic Championship, etc.: F. A. Knott, 5,000 metres Belgian record. Cycling: G. A. Olley, Land's End to John-o'-Groats record. Tennis: Eustace Miles, M.A., various championships, etc. Of especial interest at the present moment are a series of tests and experiments recently carried out at Yale University, U.S.A., under Professor Irving Fisher, with the object of discovering the suitability of different dietaries for athletes, and the effect upon the human system in general. The results were surprising. 'One of the most severe tests,' remarks Professor Fisher, 'was in deep knee-bending, or "squatting." Few of the meat-eaters could "squat" more than three to four hundred times. On the other hand a Yale student who had been a flesh-abstainer for two years, did the deep knee-bending eighteen hundred times without exhaustion.... One remarkable difference between the two sets of men was the comparative absence of soreness in the muscles of the meat-abstainers after the tests.' The question as to climate is often raised; many people labour under the idea that a vegetable diet may be suitable in a hot climate, but not in a cold. That this idea is false is shown by facts, some of which the above quotations supply. That man can live healthily in arctic regions on a vegetable diet has been amply demonstrated. In a cold climate the body requires a considerable quantity of heat-producing food, that is, food containing a good supply of hydrocarbons (fats), and carbohydrates (starches and sugars). Many vegetable foods are rich in these properties, as will be explained in the essay following dealing with dietetics. Strong and enduring vegetable-feeding animals, such as the musk-ox and the reindeer, flourish on the scantiest food in an arctic climate, and there is no evidence to show that man could not equally well subsist on vegetable food under similar conditions.
