Metabolic Adaptations to Training

Training effect depends on type of training performed (principle of training specificity).

Aerobic training will:
Have no effect on	Increase
fiber type	muscle capillary density
anaerobic enzymes	myoglobin
buffering capacity	mitochondrial density
ATP-PCr enzymes	mitochondrial enzymes
	muscle glycogen & fat stores

Training shifts La threshold curve to the right (i.e., an athlete must run at a faster pace in order to accumulate the same amount of blood La as before training).

Anaerobic training will:
Increase	Have no effect on
ATP-PCr enzymes	aerobic enzymes
glycolytic enzymes
buffering capacity
