Hormesis is a biological phenomenon where a low dose of a potentially harmful stressor, such as a toxin or environmental factor, stimulates a beneficial adaptive response in an organism. In other words, small doses of stressors that would be damaging in larger amounts can actually enhance resilience, stimulate growth, or improve health at lower ...
The dose–response relationship, or exposure–response relationship, describes the magnitude of the response of an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after a certain exposure time. [1] Dose–response relationships can be described by dose–response curves. This is explained further ...
There is a dose-response relationship between the amount of exercise performed from approximately 700–2000 kcal of energy expenditure per week and all-cause mortality and cardiovascular disease mortality in middle-aged and elderly men. The greatest potential for reduced mortality is seen in sedentary individuals who become moderately active.
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
[19] [20] [21] There is a dose-response relationship between increased physical activity and the risk of stroke. [22] Being physically active before a stroke is associated with decreased admission stroke severity and improved post-stroke outcomes. [23]
Exercise physiology is the ... to treat various conditions using dose response prescriptions specific to each individual. ... limiting factor of this relationship in ...
The observed relationship was linear. Researchers found no significant association between milk chocolate intake and type 2 diabetes risk. Additionally, increasing milk chocolate intake was ...
PK/PD relationships can be described by simple equations such as linear model, Emax model or sigmoid Emax model. [5] However, if a delay is observed between the drug administration and the drug effect, a temporal dissociation needs to be taken into account and more complex models exist: [ 6 ] [ 7 ]
