We aim to investigate the role and biological mechanisms of the weekend warrior (WW) exercise model on depression‑induced rats in comparison to the continuous exercise (CE) model. Sedentary, WW, and CE rats were subjected to chronic mild stress (CMS) procedure. CMS and exercise protocols continued for six weeks.

Ovariectomized Sprague Dawley rats were orally given either a hormone replacement therapy (1 mg/kg/day,17β estradiol; HRT) or melatonin (4 mg/kg/day) or HRT + melatonin treatments or tap water, while each group was further divided into sedentary and exercise (30 min/5 days/week) groups. After the heart rate measurements and memory tests were performed, trunk blood was collected at the end of the 10th week to determine metabolic parameters in serum samples.

Methods: Thirty male Wistar rats were used for this experimental study.
Sepsis leads to systemic hypotension, disturbed perfusion, inflammation, and tissue toxicity in vital organs. Neuropeptide W (NPW) has modulatory effects in the control of blood pressure and inflammatory processes, implicating a potential beneficial effect against sepsis-induced oxidative damage. Under anesthesia, male Sprague Dawley rats underwent cecal ligation and puncture.
