Training theories 221018 4/5

Two models of thought predominate the current thinking in strength training. One is ‘supercompensation’ or the one-factor theory, the second is the ‘fitness-fatigue’, also known as the two-factor theory. These two are generalized theories and as such contain only the most essential portions of the training ideas. Extraneous options are not included in this brief snap shot of these two training programs.

Two factor theory (Fitness-fatigue theory)

This “theory of training is much more sophisticated than the supercompensation theory”. Its basis is the premise “that preparedness, characterized by the athlete’s potential sport potential performance is not stable but rather varies with time. There are two components of the athlete’s preparedness:

Those that are slow changing, for example, physical fitness is a slow changing phenomenon. It does not change a substantial amount over short periods of minutes, hours or even days.
Fast changing such as physical fatigue (a temporary lowered ability to work because of disturbed homeostasis resulting from performing this work ), illness, the athlete’s disposition toward competition, intellectual, and sensory inputs may all change quickly.

According to this theory, the immediate effect of the training is a combination of two processes:

  1. The gain in the fitness which was prompted by the workout
  2. Fatigue resulting from the workout

The sum of the two effects is an increase in fitness due to the workout that is offset by a deterioration of fitness due to fatigue. The outcome is a balancing act of positive and negative actions within the body. If the fitness increase is greater than the effects of fatigue, the organism grows stronger. If not the opposite is true.
