In other words, each subject experi- enced times when performance was good, and other days when it was poor. This fluctuation is commonly noted by all athletes who refer to such performances as being “hot” or “cold”. Many times these variations may be charged to changes in the surroundings such as temperature, ventilation, lighting or equip- ment. Often, though, external conditions may not be altered and yet the performance is above or below the expected level. In these fatigue experiments, for instance, variations occur despite the fact that conditions remained practically identical at all times. If con- ditions remain uniform it is obvious that the search for causes of good and bad days most often must concern itself with the per- former himself. That sets up the necessity for a complex analysis of the emotional drive or application possessed or developed by the subject. The three factors, training, conditioning, and applica- tion and the elements of which each is composed serve as a basis for this analysis of causes of fluctuations in performance. Spurters and Pacers The consideration of good and bad days introduces the con- troversy over methods of reaching maximum production. Is it 40
