Avoid Injury: Intensity and Recovery
Tissues will remodel in relation to the loads exerted on them: If your work becomes harder, you will strengthen up to match the new intensity. Contrariwise, if you then take on a sedentary job, you will become softer to match those easier needs. When increasing intensity, weather a new job or progressing a training routine, a recovery period is necessary for your tissues to heal or adapt to the new loads. You might say that the training stimulates and the recovery period creates your improvements. Keep in mind, however, too little or too infrequent exposure to training or conditioning never improves tissue resistance. Too much, too frequent or too prolonged exposure, then recovery and adaptation can't keep pace, resulting in an accumulative injury. (McGill 2000).
