Training monotony refers to a state or condition in which an athlete's training has become repetitive and lacking in variation of intensity, volume, or type of exercise. A clear example of high training monotony would be running the same route, every day, at the same pace.
In sports science, Training Monotony is a single number calculated from an analysis of workouts, to determine the statistical variation in day to day training. Research would suggest that monotony figures below 1.5 are desirable, with figures above 2.0 as potentially being a cause for concern.
Training monotony is most often considered in conjunction with Training Strain.
