Lately I have been experimenting with running at different times in the day. As you may have read in the post “An apple’s rollercoaster ride” I do have some problems with food doing a dance in my tummy whilst running
That’s why I decided to run first thing in the morning, for the following reasons :
- My run is the first thing I tackle in the day, so I can’t keep postponing it
- I don’t have stomach problems
- I feel awake and ready to start my day
The advantages on doing cardio on an (nearly) empty stomach are –>
1) Early morning before you eat, your levels of muscle and liver glycogen (stored carbohydrate) are low. If you eat dinner at 7 p.m and you eat breakfast at 7 a.m., that’s 12 hours without food. During this 12-hour overnight fast, your levels of glycogen slowly decline to provide glucose for various bodily functions that go on even while you sleep. As a result, you wake up in the morning with depleted glycogen and lower blood sugar – the optimum environment for burning fat instead of carbohydrate. How much more fat you’ll burn is uncertain, but some studies have suggested that up to 300% more fat is burned when cardio is done in a fasted, glycogen-depleted state.
2) Carbohydrate (glycogen) is your body’s primary and preferred energy source. When your primary fuel source is in short supply, this forces your body to tap into its secondary or reserve energy source; body fat. If you do cardio immediately after eating a meal, you’ll still burn fat, but you’ll burn less of it because you’ll be burning off the carbohydrates you ate first. You always burn a combination of fat and carbohydrate for fuel, but depending on when you exercise, you can burn a greater proportion of fat relative to carbohydrate. If doing cardio first thing in the morning is not an option for you, then the second best time to do it would be immediately after weight training.
3) Another benefit you’ll get from early morning cardio sessions is what is calledl the “afterburn” effect. When you do a cardio session in the morning, you not only burn fat during the session, but you also continue to burn fat at an accelerated rate after the workout. Why? Because an intense session of cardiovascular exercise can keep your metabolism elevated for hours after the session is over. If you do cardio at night, you will still burn fat during the session, so you definitely benefit from it. However, nighttime cardio fails to take advantage of the “afterburn” effect because your metabolism drops like a ton of bricks as soon as you go to sleep. While you sleep, your metabolic rate is slower than any other time of the day.
4) Burning more fat isn’t the only reason you should do morning cardio. The third benefit of morning cardio is the “rush” and feeling of accomplishment that stays with you all day long after an invigorating workout. Exercise can become a pleasant and enjoyable experience, but the more difficult or challenging it is for you, the more important it is to get it out of the way early. When you put off any task you consider unpleasant, it hangs over you all day long, leaving you with a feeling of guilt, stress and incompleteness (not to mention that you are more likely to “blow off” an evening workout if you are tired from a long day at work or if your pals try to persuade you to join them at the pub for happy hour.)
You might find it hard to wake up early in the morning and get motivated to workout. But think back for a moment to a time in your life when you tackled a difficult task and you finished it. Didn’t you feel great afterwards? Completing any task, especially a physically challenging one, gives you a “buzz.” When the task is exercise, the buzz is physiological and psychological. Physiologically, exercise releases endorphins in your body. Endorphins are opiate-like hormones hundreds of times more powerful than the strongest morphine. Endorphins create a natural “high” that makes you feel positively euphoric! Endorphins reduce stress, improve your mood, increase circulation and relieve pain. The “high” is partly psychological too. Getting up early and successfully achieving a small goal kick starts your day and gives you feelings of completion, satisfaction and accomplishment. For the rest of the day you feel happy and you feel less stress knowing that the most difficult part of the day is behind you.
Ofcourse the best time of day to do your cardio is any time! The most important thing is that you just do it.
But if you have some problems with digesting your food in time to go running, maybe you can try this way of running. If I do wake up feeling ravenous I tend to eat some dried fruit for energy or 1/2 banana..
- Are you a fan of doing cardio first thing in the morning? Do you eat something beforehand or do you just change and get out the door?
- If you’re not doing cardio in the morning, when is your favorite time to crack in a workout?
