Physical Activity May Increase Levels of Neurotrophins Like Brain Derived

True/False

Physical activity may increase levels of neurotrophins like brain derived neurotrophic factor and this could be a mechanism that explains benefits to cognitive functioning. Increases in BDNF appear to be exercise intensity dependent. Given that mental health benefits are also reported at a low intensity of exercise suggests that this mechanism is not essential for mental health benefits but may be operating for some people.
