Feeling energetic: What’s physical activity got to do with it?What are 3 key reasons to care about energy and fatigue?People learn better when they have energy- mental energy is important for living full lifeBeing productiveTo enjoy life, recreate, playAbout 25% of people are fatiguedMore women than men are fatigued on averageTotal yearly cost of fatigue globally- $500 billionLost productivity= 360 billionAccidents= 108 billionHealth care= 40 billionWhat are five key determinants of being fatigued?Genetics contributes to 50% of the variability in fatigueNumerous illnesses and treatments cause or are associated with fatigueMental health problemsCardiorespiratory illnessesChronic sleep lossChronic physical inactivityHow does physical inactivity relate to feelings of energy and fatigue?Feelings of fatigue can cause physical inactivityNumber one excuse for not working out is no timePhysical inactivity can cause fatigue symptomsHow does physical activity relate to feelings of energy and fatigue?Sleep betterlong term sleep may enhance athletic performanceTake certain foods, beverages, or drugs: they either stimulate the brain directly or allow changes to happen during sleep that can act as if it’s stimulating the brainCaffeine, nicotine, ephedrine, Adderall, modafinilMental energy (selective attention) is improved after a glucose mouth rinse as well as endurance performanceCaffeine improves feelings of energy and cognitive performance (sustained attention) as well as enduranceOn average 18% improvement in endurance and 7% in strength testingIncrease sensory stimulationEngage in brain-activating behaviorsA single bout of exercise energizesExercise intensity moderates the effectOutdoor exercise may be better than indoor exercise because of the sunlight: acute exerciseRegular exercise can alleviate and cause fatigue: chronic exerciseMood worsens with high volume exercise trainingKINS 2010 1st Edition Lecture 17Outline of Last Lecture I.
