Lecture 16 cognitive function & exercise: rct: groups at risk for alzhei(cid:373)er"s a(cid:374)d/or (cid:272)o(cid:373)plai(cid:374)i(cid:374)g of (cid:373)e(cid:373)or(cid:455) pro(cid:271)le(cid:373)s exercise vs control 142 minutes for 42 weeks exercise group gained brain function. You can measure using reaction time and accuracy tests . Eriksen flanker test, task switching test, stroop color and word test: with age, grey matter (neurons) + white matter (connections) + ventricular size = Single exercise bouts can enhance st ability to process information (measure using reaction time testing). Settings but promising results: pa can also help cognitive function in children/adolescents academic achievement, More body fat predicted worse performance: review on children showed positive associations among pa, fitness, cognition, and academic achievement. Single bouts as well as interventions improve performance on (cid:272)og(cid:374)iti(cid:448)e tasks! Neurogenesis (new neurons) + neuroplasticity (new connections b/w neurons) + synaptic plasticity (connections between neurons to change in strength: bdnf = brain-derived neurotrophic factor; w/exercise; essential for hippocampal function, synaptic plasticity, and learning.
