Acute effects of excess alcohol on the body:(10)
Acute = after single consumption * Hydration and kidney function * Increase in ADH production → dehydration * Cardiovascular system * Reduced heart rate * Thermoregulation * Reduced core body temp partially due to vasodilation at skin * Neurologic systems * Lose inhibitions * Loss of coordination and concentration * Slurred speech and vision impairment
Chronic impacts of excessive alcohol intake on body systems:(4)
Chronic = after many years of consumption 1. Liver * Inflamed liver/ liver disease * Cirrhosis / scarring * Cancer * Fatty liver disease 2. Kidney * Kidney failure 3. Heart * High blood pressure / stroke 4. Brain * Loss of memory * Causes poor muscle coordination * Anxiety and depression * Causes mental confusion * Cerebral hemorrhage
Alcohols impact on performance: (positives and negatives -8)
Positive effects (ergogenic) * Reduced tremors (shooting sports) - only 1 drink Negative effects (ergolytic) * Distorted balance/ coordination * Impaired cardiac function * Reduced power/speed/strength * Inhibited cognitive processing/reaction time * Inhibition of gluconeogenesis * Lowers body temperature * Impairs vision/blurred vision * Causes dehydration which can impair performance
