The effects of low-intensity resistance training with or without blood flow restriction on serum BDNF, VEGF and perception in patients with post-stroke depression.

There were no statistical differences between the RPE, BLA, BDNF, and VEGF levels of each group before exercise. After exercise, the RPE, BLA, and BDNF levels of the LOW group increased significantly (P < 0.05); the change in VEGF level of the LOW group was not significantly different from that before exercise (P > 0.05), and the indexes of the L-BFR group and the HIGH group were significant after the increase in exercise (P < 0.05). Analysis between groups showed that the changes in BLA, BDNF, and VEGF levels in the L-BFR group and HIGH group were higher than those in the LOW group, and the statistical difference was significant (P < 0.05); there was no change between the statistical difference of the L-BFR group and HIGH group (P > 0.05). The difference in RPE before and after exercise in the HIGH group was significantly higher than that in the L-BFR group (P < 0.05) and the difference in RPE before and after exercise in the L-BFR group was significantly higher than that in the LOW group (P < 0.05). Blood flow restriction resistance exercise may increase the serum BNDF and VEGF levels of PSD patients by increasing the body's BLA concentration. Although its effect is similar to that of traditional high-intensity resistance exercise, subjective physical strength is lower during blood flow restriction resistance exercise.
