Effect of 24-hr REM-SD on memory impairment induced by intensive exercise. After 5 weeks of intensive exercise, ExSd group of animals received eight trials in a day and immediately went under 24-hr REM-SD. (A) Escape latency, (B) traveled distance and (C) swimming speed across eight trials. Values are given as mean±SEM for each experimental group. Probe test was done immediately after the 24-hr REM-SD. (D) Percentage of time spent in target quadrant. Data are shown as mean±SEM. *p˂ 0.05 and **p˂0.01 different from the control group. ^#p˂ 0.05 different from the Exercised group. ^{^^^}p˂ 0.001 different from the 24h REM-SD group. Each bar represents mean±SEM per group. (E) Escape latency during non-spatial visible platform test. p>0.05 NS (not significant).
