Macedon, competed in the foot-race at Olympia. Competition naturally raised the standard of athletics. Natural ability and ordinary exercise were no longer sufficient to secure success without long and careful training. Hence there arose a class of professional trainers. These men, who were often old athletes, acquired considerable repute, and doubtless were handsomely rewarded by the rich individuals or states that employed them. In their hands athletics became scientific; instead of being regarded as a recreation and a training for war they became an end in themselves. One state alone, Sparta, held aloof from the new athletics and competitions. At Sparta the one object was to produce a race of hardy soldiers, and the new science, which aimed at producing athletes, could find no place there. No Spartan was allowed to employ a trainer in wrestling. Boxing was said to have been introduced by the Spartans, but though they recognized the value of boxing as a sport, they realized the dangers of it as a competition, and forbade their citizens to take part in competitions for boxing or the pankration, on the ground that it was disgraceful for a Spartan to acknowledge defeat. Hence the disappearance of Sparta from the list of the Olympic victors which has already been noticed. Sparta in athletics fell behind the rest of Greece, and Philostratus, comparing them with the more scientific athletics, describes them as somewhat boorish.[94] Yet perhaps the Spartans and Xenophanes were right.
