Answer:
Explanation:
During exercise athletes should consume 30–60 g carbohydrates per hour (or 0.7 g/kg of body weight) in order to maintain blood glucose levels. This is of extreme importance when the event lasts more than an hour and it takes place in extreme environmental conditions (cold, heat or high altitude).
Answer:
b. Basilic vein.
Explanation:
According to my research on studies conducted by various medical professionals, I can say that based on the information provided within the question the vein that causes more complaints when drawing blood is called the Basilic vein. This is because the Basilic vein has an artery and a nerve running right below it, therefore it is a lot more painful and also runs the risk of damaging the nerve in the process.
The median cubital vein lies between muscles and is usually the most easy to puncture. Under the basilic vein runs an artery and a nerve, so puncturing here runs the risk of damaging the nerve or artery and is usually more painful.
