Abstract

Neuropeptide Y (NPY) and catecholamines are synthesized in response to stress. Adrenal NPY mRNA and tyrosine hydroxylase (TH) mRNA were measured by Northern analysis 2 h after a single 20 min bout of shaker stress in exercised and sedentary male Sprague-Dawley rats. Long-term exercise (18 weeks of voluntary wheel running) alone did not significantly alter adrenal NPY mRNA or TH mRNA levels. However, increases in stress-induced NPY and TH mRNA abundances were significantly enhanced by long-term exercise (P < 0.01). These results suggest that long-term physical activity may enhance the ability to synthesize NPY and catecholamines under conditions of stress.
