The term Lucy comes from the song by the Beatles Lucy in the Sky with Diamonds which is commonly thought to be about LSD. Lucy is often used as a code word for LSD when referring to the drug in a public setting or over the phone where one does not want to openly discuss illegal activities. Lucy is used like a person's name in such discussions. Like saying Lucy took me on a trip last night to indicate you tripped on LSD the previous night. I tripped balls with Lucy last weekend!
The capacity of your body to store muscle and liver glycogen, however, is limited to approximately 1,800 to 2,000 calories worth of energy, or enough fuel for 90 to 120 minutes of continuous, vigorous activity.
The body uses this glucose in the blood for energy. Most glucose is stored as glycogen in the liver and muscles. During exercise glycogen is broken down in the muscles and provides energy. Usually there is enough glycogen in muscles to provide fuel for 90-120 minutes of exercise.Most exercise and sport games do not use up glycogen stores so eating carbohydrates during the activity usually isn't needed.hether it's playing football, swimming, jogging, kick-boxing or walking, active people (people who have rigorous exercise routines or play sports) or athletes need to eat a nutritious, balanced diet to fuel their body. Good nutrition, like any sporting event, has basic ground rules.
