Neural factors
Chemical factors
Nervous stimulation of the muscle is detected by proprioreceptors
Presence of adrenaline and noradrenaline in the blood
Joint movement awareness recognised by proprioceptors
Carbon dioxide production in the muscle
Thermoreceptors detect increased blood temperature
Partial pressure of oxygen is detected in the capillaries at the lungs
Increase in skin temperature is detected by thermoreceptors
The elastic stretch of the lungs during forced inhalation is detected by baroreceptors
Increase in muscle temperature is detected by thermoreceptors
pH of the blood (i.e. acidity from increased lactic acid) is detected by chemoreceptors in the aorta and carotid arteries
Decrease in oxygen levels
Baroreceptors detect differences in pressure
Presence of hydrogen ions that dissociate from lactic acid during high-intensity exercise
