Studies that have mapped the connections between neurons in the brain‚ gain insight into the regulation of appetite and metabolism. The ARC and VMH has long been thought of as satiety centers. Studies that investigate the role of the arcuate nucleus in the hypothalamus‚ in regulating appetite and metabolism‚ have targeted two chemically identified neuronal types within the ARC: anorexigenic pro-opiomelanocortin (POMC) neurons and orexigenic neuropeptide Y (NPY)/agouti-related peptide (AgRP) neurons

(Connett & Sahlin‚ 1996). Contractions require energy in the form of adenosine tri-phosphate (ATP). ATP stores in muscle are around 8mmol/l and are exhausted within 2s of exercise (Connett & Sahlin‚ 1996). To continue exercise and maintain ATP homeostasis‚ ATP production must increase rapidly. The adaptations that occur are tailored to suit the energy requirements of the exercise‚ therefore the adaptations during marathon running are different to those seen during sprinting.
