BMI is KG/meters^2 how would you classify someone with a bottom mass of 96 KG in a height of 2 m. 19 = underweight/increased health risk 19-25 is desirable 25 to 30 is overweight/increased health risk 30 to 40 is OB/high health risk 40+ is extreme obese/extremely high heart real risk

BMI is not a good indicator of body composition or health risk

The primary fuel for high intensity aerobic exercise is

When skilled muscle glycogen is depleted in an endurance

When skeletal muscle glycogen is depleted in an endurance event

which can provide substrate for anaerobic ATP production

A group of subjects do a aerobic exercise training on either high carbohydrate or low carbohydrate, diet afterword, which group has the longer exercise time to exhaustion

Caloric expenditure depends on

An ultra endurance athlete ran about 1000 km in five days as caloric intake over the run was nearly identical to his caloric expenditure was this guy likely to have lost fat over the run

an athlete least likely to be at risk for nutritional insufficiency calories is vitamins minerals is in

for most exercise activities (except long events, for which suppression of fat oxidation by insulin would limit performance) the recommendation pre-exercise meal is

The exception to the above is a long event like a marathon for which a carbohydrate meal that increases insulin with suppressed lipolysis and shift oxidative substrate through carbohydrate depleting glycogen more quickly before this event that preferred meal would be

After exercise replenishment of blood glycogen stores is best done immediately by ingesting
