Abstract

Background Hypertension and myocardial infarction account for the high rate of mortality globally. Hibiscus sabdariffa (HS) Linn. is rich in antioxidants and previous studies have demonstrated its anti-hypertensive effects. Several studies show that regular physical activity is an important component to reduce cardiovascular mortality. The objective of this study was to evaluate the effects of a combination of aerobic exercise and HS extract on nitric oxide (NO) and endothelin-1 (ET-1) in rats. MethodsAn experimental study was conducted on 36 male Wistar rats, aged 4 weeks and 60-70 g in weight. The interventions were aerobic exercises and HS at 400 mg/kg BW/day administered for 4, 8 and 12 weeks. The rats were randomized into 12 groups: 3 control groups (C4, C8, C12), 3 aerobic exercise groups (A4, A8, A12), 3 HS groups (H4, H8, H12), and 3 combination groups [aerobic exercise and HS] (HA4, HA8, HA12). After 4, 8, and 12 weeks, the rats were sacrificed and their abdominal aorta was collected for determination of nitric oxide and ET-1 concentrations. One way ANOVA was used to analyze the data. ResultsThere was a significant difference in NO levels between all groups, with the 4-week aerobic exercise group (A4) showing the highest NO levels compared to the other eleven groups (p<0.05). In contrast, the ET-1 levels were not significantly different between all groups. Conclusions This study demonstrated that the combination of HS supplementation and aerobic exercise increases NO in rats, and provided further evidence to the traditional use of the plant as an antioxidants agent.

Abstract

HIIT has been known to improve cognitive function. In addition to its effect on the hippocampal area. After HIIT training, BDNF levels also increase in the spinal cord, cerebellum and several cortical areas through increasing levels of Insulin-like Growth Factor-1 (IGF-1). In neurons, BDNF is present not only in the cytoplasm, but also near the dendritic spines, which influences their development. BDNF stimulates the process of neuroplasticity, which is manifested in neurogenesis, stimulation of the plasticity of serotoninergic, dopaminergic, cholinergic or noradrenergic neurons, dendritogenesis, and synaptogenesis. Moreover, BDNF facilitates the growth and survival of neurons and microglial cells. It also participates in cell differentiation, potentiation of signal transmission, induction, and maintenance of long-term potentiation of the synapse enhancement. Because of these properties, BDNF enhances cognition and takes part in emotional processes, spatial orientation and learning, as well as body coordination. Evidence suggests that IGF-1 is a major determinant of the effect of physical exercise on BDNF levels and thus on cognition more generally. There is an upregulation of Fndc5 gene expression in skeletal muscle and an increase in irisin after prolonged resistance training in rats and humans following HIIT training. When hippocampal Fndc5 was upregulated during exercise, BDNF and other neuroprotective genes were also activated in the rat hippocampus. Exercise-induced adult hippocampal neurogenesis is associated with increased Fndc5 and BDNF genes thus enhancing cognition. Then, stroke is associated with neuroinflammation that affects the processes of neuroplasticity in the lesion core, penumbra and small areas such as the spinal cord.
