Which situation would be overtraining?

Generally speaking, athletes train to increase performance. Performance increases are achieved through increased training loads. Increased loads are tolerated only through interspersed periods of rest and recovery—training periodization. Overreaching is considered an accumulation of training load that leads to performance decrements requiring days to weeks for recovery. Overreaching followed by appropriate rest can ultimately lead to performance increases. However, if overreaching is extreme and combined with an additional stressor, overtraining syndrome (OTS) may result  OTS may be caused by systemic inflammation and subsequent effects on the central nervous system, including depressed mood, central fatigue, and resultant neurohormonal changes
