    morning cardio


    To my understanding when one does cardio first thing in the morning before eating it raises ur metabolism. I've also read that one should take in whey first thing in the morning so that you get amino acids to your muscles after the overnight fast. So my question is does that whey I drink before I do my cardio going to lower the effects of doing cardio before eating? Or is that litte bit of whey I drink (20 grams) not realy count as food?

    You do not have to have whey first thing in the morning. However, if you DO have it before doing cardio first thing, it's not going to lower the effects of doing cardio before eating, no - although whey is insulinogenic, it's not going to elicit the same effect as food. And studies have proven that doing cardio fasted is not any better than doing it unfasted - what you decide to do is based more on personal preference.

    So is cardio in the morning raises metabolism a myth?

    Any exercise is the morning is going to raise your metabolism because you're going from an inactive to an active state. Eating also gets your metabolism going. At the end of the day, do what's most convenient for YOU.

    Hey I don't like fasted cardio, I wake up and feel way to hungry and tired, however I LOVE low intensity cardio after weight training, works well for me

    ^^ Exactly, in fact, fasted cardio may be less effective than fed cardio, especially if you plan to do it with any intensity/effort:

    Myths Under The Microscope Part 2: False Hopes for Fasted Cardio

    By Alan Aragon © 2006





    False Hopes

    The bandwagon is lead by blind horses

    Many trainees pigeonhole weight training as an activity exclusively for building muscle, and cardio exclusively for burning fat. On the contrary, weight training can yield very similar results to cardio of similar intensity when 24-hr energy expenditure and macronutrient oxidation is measured [1]. The obvious advantage of weight training is the higher potential for lean mass and strength gains. In the bodybuilding context, cardio should be viewed as merely an adjunctive training mode to further energy expenditure and cross-complement the adaptations specific to weight training. As far as cardio being absolutely necessary for cardiovascular health, well, that depends upon the overall volume and magnitude of your weight training - another topic for another time.

    Chaos theory strikes again

    On the surface, it seems logical to separate carbs from cardio if you want a maximal degree of fat oxidation to occur during training. But, there’s the underlying mistake - focusing on stored fuel usage during training instead of focusing on optimally partitioning exogenous fuel for maximal lipolytic effect around the clock. Put another way, it’s a better objective to coincide your carb intake with your day’s thermic peaks, where insulin sensitivity & lean tissue reception to carbs is highest. For some reason, this logic is not easily accepted, nor understood. As we know, human physiology doesn’t always cooperate with logic or popular opinion, so let’s scrutinize the science behind the claims.

    Let The Research Speak

    Carbohydrate ingestion during low-intensity exercise reduces fat oxidation

    As far as 3 decades back, Ahlborg’s team observed that carb ingestion during low-intensity exercise (25-45% VO2 max) reduced fat oxidation compared to fasted levels [2]. More recently, De Glisezinski’s team observed similar results in trained men at 50% VO2 max [3]. Efforts to determine the mechanism behind this phenomenon have been made. Coyle’s team observed that at 50% VO2 max, carbohydrate availability can directly regulate fat oxidation by coordinating hyperinsulinemia to inhibit long-chain fatty acid transport into mitochondria [4].

    Carbohydrate’s effect on fat oxidation during moderate-intensity exercise depends on conditioning level


    Civitarese’s team found glucose ingestion during exercise to blunt lipolysis via decreasing the gene expression involved in fat oxidation in untrained men [5]. Wallis’ team saw suppressed fat oxidation in moderately trained men & women when glucose was ingested during exercise [6].

    In contrast to the above trials on beginning and intermediate trainees, Coyle’s team repeatedly showed that carb ingestion during moderate-intensity (65-75% VO2 max) does not reduce fat oxidation during the first 120 min of exercise in trained men [7,8]. Interestingly, the intensity margin proximal to where fat oxidation is highest was unaffected by carb ingestion, and remained so for the first 2 hours of exercise.

    Horowitz’ team examined the effect of a during-training solution of high-glycemic carbs on moderately trained men undergoing either low intensity exercise (25% VO2 max) or high-moderate intensity (68% VO2 max) [9]. Similar results to Coyle’s work were seen. Subjects completed a 2-hr cycling bout, and ingested the carb solution at 30, 60, and 90 minutes in. In the low-intensity treatment, fat oxidation was not reduced below fasted-state control group’s levels until 80-90 min of exercise. In the 68% group, no difference in fat oxidation was seen whether subjects were fasted or fed throughout the trial.

    Further supporting the evidence in favor of fed cardio in trained men, Febbraio’s team investigated the effects of carb ingestion pre & during training in easily one of the best-designed trials on this topic [10]. Subjects exercised for 2 hrs at an intensity level of 63% VO2 max, which is now known as the point of maximal fat oxidation during exercise. Result? Pre & during-training carbs increased performance - and there was no difference in total fat oxidation between the fasted and fed subjects. Despite the elevated insulin levels in the carb-fueled groups, there was no difference in fat availability or fat utilization.

    Summing Up the Research Findings

    • At low intensities (25-50% VO2 max), carbs during exercise reduce fat oxidation compared to fasted trainees.
    • At moderate intensities (63-68% VO2 max) carbs during exercise may reduce fat oxidation in untrained subjects, but do not reduce fat oxidation in trained subjects for at least the first 80-120 minutes of exercise.
    • Carbohydrate during exercise spares liver glycogen, which is among the most critical factors for anticatabolism during hypocaloric & other conditions of metabolic stress. This protective hepatic effect is absent in fasted cardio.
    • At the established intensity level of peak fat oxidation (~63% VO2 max), carbohydrate increases performance without any suppression of fat oxidation in trained subjects.

    I love Cardio in the morning because it starts my day out right.
    I take about 10 grams protien before and 15 grams after.

    Hi,,,
    Cardio is an exercise in which the heart rate increase to a certain extent.It is much better to use small amount of Whey protein or any other protein shake before doing Cardio in the morning.

    I like to take 10 grams BCAA before fasted cardio. Then drinking a shake after. Any reason a shake works better then a BCAA

    I prefer morning cardio fasted, but I can't do cardio at any time of day with much on my stomach. I really like a good dose of beta alanine and some bcaas.

    morning cardio sucks, frikken hate it. I've just woken up from 8 hrs without food, I benefit more from breakfast first thing than a.m. cardio. This just my opinion

    I love reading about this debate, a lot of people have diff opinions on this, Ive always at half a protein bar w/ peanut butter on it before cardio, then a shake afterward

    I use this protocol period whether fasted, pre/post weight training, or cardio only days. However I use MAP now instead of BCAA's.

    I only do med. intensity for 15~20min before I go to work, and burn 200 or so calories, so nothing major. Some BCAA's and a no calorie caffiene drink before and during and away I go!!

    I think it burns more fat than any other cardio, except MAYBE after weightlifting.
    True story:

    I give a f**K!!
