I think it means meal! For example, with the word "postprandial", it means after eating a meal. Hope I helped! :)
It usually depends on your schedule if your busy and work late I'd say 7-10 hrs but if you are a normal average person 8 hrs will do the trick
Cardiovascular fitness is best described as B. the ability of the body
to transport oxygenated blood efficiently. Cardiovascular fitness is
improved by regular aerobic exercises and help to strengthen the cardiac
muscles, making the heart more efficient in pumping blood through the
body. Moreover, cardiac efficiency decreases the resting heart rate of a
person as their heart is more effective in transporting blood with each
contraction.
