During strenuous exercise blood flow increases to skeletal muscles. This happens without the involvement of the nervous and endocrine systems. What kind of homeostasis regulation is this and why does it happen without input from the nervous and endocrine systems

Depletion of ATP in the skeletal muscles to AMP results in the activation of AMPK which increase glucose uptake in the skeletal muscles cells. This effect is similar to that initiated by the insulin hormone. With the reduction of blood glucose in the blood stream, the liver will increase gluconeogenesis and glycogenolysis to release more glucose into the blood and blood flow is increased to supply sufficient oxygen and glucose to skeletal muscles for it to generate ATP (I am assuming exercise here refers to aerobic exercise). In this case, the homeostasis regulation involved is that of the blood glucose. It does not involve the nervous and endocrine systems as it is activated by the depletion of ATP in skeletal muscles itself.

Autoregulation or intrinsic homeostasis regulation is the type of homeostasis regulation that takes place without input from the nervous and endocrine systems.

During strenuous exercise, the blood vessels of a particular muscle dilate to increase the blood flow to the active muscles, with increased intensity of the exercise metabolic activity in the muscles increases too.

In this case, demand for oxygen increases, so it requires to increase blood to the required tissues, So the extra demand of blood flow cannot be met by neural and endocrine mechanism alone, so it has to depend upon local factors known as Autoregulatory mechanism, this homeostatic mechanism ensures adequate blood flow to active muscle tissues.

Autoregulatory mechanisms require neither specialized nervous system nor endocrine control, rather these are the local self regulatory mechanism that allows each region of tissues to adjust its blood flow (perfusion). These local mechanisms include chemical and myogenic controls.
