International Journal of Exercise Science 7(3) : 186-193, 2014. Long-term physical exercise has been shown to noticeably reduce blood pressure (BP) and remarkably attenuate symptoms of hypertension. It is believed that physical exercise induces these beneficial effects by increasing the blood supply to the brain, enhancing the release of growth factors from skeletal muscles into the bloodstream, facilitating neurogenesis, stimulating angiogenesis, and influencing endothelial cell proliferation and subsequent endothelial cell membrane permeability. Previous findings also revealed that physical exercise significantly elevates brain-derived neurotrophic factor (BDNF) concentrations which appear to increase dramatically in BP-sensing neurons during hypertension. Elevating BDNF levels is …
The Relationship Between Percent Change In Salivary Α-Amylase Activity And Fitness Level (Vo2peak And Anaerobic Threshold) Following Maximal Cycling Exercise In Moderately Trained Male Individuals, Nobuo Yasuda
International Journal of Exercise Science: Conference Proceedings
PURPOSE: Salivary α-amylase has been proposed as a biomaker for autonomic nervous system activity as well as mucosal immune function given that its realase into saliva is elicited by the stimulation of the salivary glands by sympathetic and parasympathetic activities. Clarifying how a individual’s fitness level will influence on the secretion of salivary α-amylase in response to exercise is a critical biological determinant of vulnerability to psychological and physiological stress. Although previous studies have shown the correlation between salivary α-amylase and exercise intensity, the relationship between autonomic nervous system activity and fitness level such as peak oxygen uptake (VO2 …
