identify the nutritional changes during environmental heat on the human body without error.
Nutritional needs include minimal changes in macronutrients (carbs, protein, and fat) and overall calorie requirements, but your body does require more calories in heat.
identify the physiological effects of environmental heat on the human body without error
your body can no longer compensate for the increasing demands of exerciseneither your muscles nor your skin can receive adequate blood flowincreases oxygen uptake, causing the working muscle to use more glycogen and produce more lactate
describe physiological effects with acclimatization in environmental heat without error.
Sweating begins earlier and capacity nearly doublesSweat dilutes with fewer electrolytesHeart rate improvesReduces rate of glycogen use 50-60%
identify the nutritional changes during environmental cold on the human body without error
Nutritional needs are an increase in carbohydrates and calorie requirements, while in a cold environment.
identify the physiological effects of environmental cold on the human body without error.
weaker muscle contractionDecreased metabolic responsesIncrease hormone outputincrease in urine output and depressed sensitivity to drinking fluids.
identify the role of body size & composition in environmental cold without error.
Insulating the body against cold is the most obvious protection against hypothermia.
identify physiological changes in a hypobaric environment without error
you have to breathe more frequently and work harder to maintain the amount of oxygen in your bloodReduced VO2 Maxaerobic activities are impaired, anaerobic activities lasting less than 1 minute are generally not impaired by moderate altitude.to suppress appetite and loss of mass
