Effect of eight weeks of interval training on insulin signaling and neurodegeneration in the hippocampus of Methamphetamine-treated rats

: This study investigated the effect of eight weeks of interval training on insulin signaling and neurodegeneration in the hippocampus of methamphetamine (METH)-treated rats. Thirty-two male Wistar rats were randomly divided into four equal groups (n = 8): saline, METH-1 (21-days of injection period), METH-2 (21-day injection period, followed by 8-week withdrawal), and METH+moderate-intensity interval training (MIT). Methamphetamine was injected intraperitoneally at 5 mg/kg per day for a...
