The training load includes the totality of the load stimuli acting on the organism. A distinction is made between external and internal stress.
The external training load is recorded quantitatively. It is data on distance, speed, time, etc. …
The internal training load represents the reaction of the organism to the external load. It can be represented mainly by physiological and biochemical parameters (heart rate, lactate, urea) and thus shows the degree of training load for the individual athlete.
If training planning is to be successful, targeted control of the training load is essential. Thus, training stimuli can provoke fatigue, which is eventually translated into a better performance state during the recovery phase, through supercompensation.
If the training load is too high, poorly coordinated and with too few rest periods, there is a risk of overtraining.
