Carbs & Exercise: The Dynamic Duo ๐๐ดโโ๏ธ
-
Big Idea: What you eat, especially carbs, affects how well you perform in sports.
-
The Carbohydrate (Carb) Story
- Both aerobic (like jogging) and anaerobic (like sprinting) systems need carbs to make ATP, the energy molecule.
- Think of ATP like the battery of our muscles!
- From sprinting (less than a minute) to marathons (several hours), carbs got your back!
The Storage Issue ๐ฆ
- Our body isn't a big carb warehouse. Here's the carb inventory
- Muscles: 400 grams
- Liver: 100 grams
- Blood: Just a few grams
- Energy Density
- Carbs: 1760 kJ per 100g
- Fat: 4000 kJ per 100g
- Cool Fact: Healthy, active peeps have enough stored carbs for 1.5-2 hours of non-stop action.
The Great Glycogen Game ๐ฎ
- Muscle Work
- Moderate Exercise: Activates slow-twitch fibers.
- Intense Exercise: Calls up the fast-twitch fibers too.
- FYI: Glycogen is like the fuel in individual muscle cells.
- Cool Experiment Alert: Jonas Bergström & Eric Hultman's bicycle study in 1966. Takeaways:
- Glycogen powers up only the muscle it's stored in.
- Running out of carbs = hitting the wall = major fatigue! ๐ฅด
- Eating lots of carbs after exercising can DOUBLE the initial glycogen stored in the muscles!
The Art of Carbo Loading ๐๐๐ช
- Athletes "carbo-load" to store more energy. More glycogen = more stamina!
- Real-world Example: A runner carbo-loading before a marathon to ensure they have energy till the finish line.
