Coke Exec Answers Questions

Everyone's heard of the ban on sugary drinks NYC Mayor Bloomberg wants to implement. But, what does a Coca-Cola executive have to say about it? The interview is quite entertaining, but here's a highlight:

Q: What sugary drink limits do you place on your kids?

A: My job as a parent is to guide them through the day to make the best choices. If my son has lacrosse practice for three hours, we go straight to McDonald's and buy a 32-ounce Powerade.

Thank goodness for McDonald's! Personally, I'd rather stop at a convenience store to pick up Powerade rather than "guide" my children to look to McDonald's for anything - even if it is just a drink.

Read the story, you'll get a chuckle.

Q&A: Pre-Competition Carbohydrate Loading

Q: I have a question, Do you know or have an opinion on whether or not carb loading the night before a sports match (in this case a crew regatta/race) is beneficial?

A: This is a great question and something I haven’t considered much lately. My opinion is that carb loading is unnecessary for 99.9% of the population and is most likely to lead to gastric distress, not faster race times.

However, I’m quick to admit when a question is treading upon territory I rarely visit and this area is not my specialty. So, I consulted a couple sources to see what the research is saying.

First up, a study regarding carbohydrate loading and resistance training (The effects of carbohydrate loading on repetitive jump squat power performance.):

…only few data are available on the effects of CHO loading on resistance exercise performance. Because of the repetitive use of high-threshold motor units, it was hypothesized that the power output (power-endurance) of multiple sets of jump squats would be enhanced following a high-CHO (6.5 g CHO kg body mass(-1)) diet compared to a moderate-CHO (4.4 g CHO kg body mass(-1)) diet. Eight healthy men (mean +/- SD: age 26.3 +/- 2.6 years; weight 73.0 +/- 6.3 kg; body fat 13.4 +/- 5.0%; height 178.2 +/- 6.1 cm) participated in 2 randomly assigned counterbalanced supplementation periods of 4 days after having their free-living habitual diet monitored. The resistance exercise test consisted of 4 sets of 12 repetitions of maximal-effort jump squats using a Plyometric Power System unit and a load of 30% of 1 repetition maximum (1RM). A 2-minute rest period was used between sets. Immediately before and after the exercise test, a blood sample was obtained to determine the serum glucose and blood lactate concentrations. No significant difference in power performance existed between the 2 diets. As expected, there was a significant (p </= 0.05) decrease in power performance between the repetitions in every set. Blood lactate concentrations were significantly higher postexercise with both the high-CHO and the moderate- or lower-CHO diet, but there were no differences between conditions. The results indicated that the power output during multiple sets of maximal jump squats was not enhanced following a higher-CHO diet compared to a moderate- or lower-CHO diet. These data show that elevated carbohydrate intake is not needed to optimize a repetitive power-endurance performance when it is done as the first exercise in a workout.

The second reference I’m using is the position of the International Society of Sports Nutrition and is looking at endurance performance:

• Part of all the ergogenic effect of carbohydrate loading recorded in most studies to date could be attributed to a placebo effect (endurance athletes are typically well educated and would expect a performance boost thus introducing a psychologic bias).

• The performance-enhancing effect of carbohydrate loading is small and in real-life competition most likely only significant in influencing the finishing order among top elite-level cyclists, not “back-of-the-pack” cyclists.

• Consuming adequate carbohydrate during prolonged exercise (at least non-steady events)may be more important that glycogen supersaturation via carbohydrate loading before exercise.

Another side to the above research worth pointing out is that the control groups are always consuming PLENTY of carbohydrates already! The first study has the controls at 4.4 g CHO/kg bodyweight while the second position from the ISSN is citing a study in which the control was at 6.0 g CHO/kg bodyweight!

This brings me to my own question: What happens if you purposely deplete glycogen stores and then try to resaturate them immediately prior to a race or competition?

Recently, I noted that the strength/conditioning coach for University of Maryland’s women’s basketball team imposed a period of carbohydrate depletion to quickly establish improved glycogen sensitivity to help power them through the ACC tournament. I can’t tell you for certain if this worked, but in theory I think it’s a great approach. It’s common practice among physique athletes (i.e., bodybuilding, figure, etc.) to deplete carbohydrate stores leading up to a competition only to really load up the day of the show. The goal being to “fill out” the muscles again. This doesn’t have anything to do with athletic performance, but worth noting.

To get back to your question: no, I don’t think it’s worthwhile to carbohydrate load the night before (or even three days before) a competition. My advice would be to moderately increase carbohydrate in the hours before a race. Begin with a carbohydrate dense meal at four-hours out, a well-tolerated and significant carbohydrate dense snack at two-hours out, and then sports drink from then on.

Hope this helps!

What Should You Eat (or Drink) Before and After a Workout?

This is a common yet important question I receive all the time, so I thought it may interest many of you readers if to briefly discuss it here on SAPTstrength. Now, this topic can get pretty geeky pretty fast, so my goal here is to KISS, give you a quick n' dirty rundown, and avoid delving into the myriad metabolic consequences of resistance training (shifts in hormonal release, the acute and chronic shifts in protein balance, up- and down-regulation of androgen and other specific membrane-bound receptors, etc.), how your pre/peri/post-training nutrition can specifically enhance/attenuate these positive/negative consequences, and related topics that I'm sure the majority of you would rather swallow nuclear waste than read about.*

I realize that most of you only care about the "Okay, so what do I actually do?" question as opposed to all the fancy schmancy science, and "whys" of the issue. (At least I think this is an accurate statement.)

I'll cut right to the chase: The supplement industry will have you believe that you need a very specific formula of proteins, carbohydrates, and [insert X superduperawesome compound necessary to become a walking science experiment and stun your peers into submission]. They tell you that if you don't take their product, then you won't maximize the results of your workout (be it muscle building, fat loss, or athletic performance) and you won't recover as quickly/optimally betwixt training sessions.

Is there any merit to consuming a beverage containing a specific carb:protein ratio (usually 3:1 or 4:1)? Yes.

Do these supplements "work"? Yes. (depending)

Have I ever taken them/recommended them to my athletes and clients? Yes. (minus the ridiculous over-the-top supplements)

Are they necessary to achieve your goals and are you a fool not to take them? NO.

Do I still take them? No. (unless you include fish oil or Vitamin D in this equation)

The bottom line is that nearly any combination of healthy proteins, carbohydrates, and fats pre- or post-training will be plenty sufficient in terms of supplying your body with the necessary nutrients to supply energy and boost recovery.

Here is what I am currently ingesting post training....

Example 1 (Homemade Shake)

  • Almond Milk
  • (Raw) Coconut Milk
  • Protein Powder
  • Banana
  • Mixed Berries
  • Gatorade Powder (for some extra sugar)
  • Brazil Nuts (sometimes)
  • Kale (sometimes, although I should include it all the time)

Example 2 (A Meal)

  • Chicken or Steak (any dead animal flesh will suffice)
  • Potato (sweet or baked)
  • Mixed Veggies
  • Strawberries (or any other fruit)

Try to get your post-workout "feeding" in you within 30-45 minutes of your training session.

As for before training, consume something that is easy on your stomach. It might be similar to the shake I provided above, or something as simple as a banana (or apple) with peanut butter.

It really doesn't need to be more complicated than that.

I'll tell you what, I used to construct my own "optimal" workout drink containing 50g dextrose (simple sugar), 20g whey protein, 5g Leucine (the golden child of amino acids), 5g Glutamine, and even some Vitamin C and E for good measure.

This was the "pefect" post-workout beverage (if there is a such thing), yet am no longer worrying about ingesting that specific of a formula. And you know what? I'm still alive. I'm still getting stronger. I'm still building muscle. My body fat is still at a healthy level. And I recover just as quickly as before. What do you know.....

What do I believe is even more important than your pre/peri/post workout beverage?

Yes, ingesting a quality meal shortly after training will do wonders for your recovery and aiding you in your goals. But you know what? I feel that some of us get so caught up in the intricacies of workout shakes that we miss the big picture.**

Instead of worrying about how many simple sugars we're receiving pre/post training, why don't we concentrate on giving it our all during a set of squats, deadlifts, or chinups?

Instead of wondering if our shake will help us recover fast enough, why don't we make a wholehearted effort to get a full night's sleep and partake in other stress-reducing activity throughout the week?

Rather than stressing over whether or not we remembered to put extra leucine in our shake, why don't we focus on consuming quality foods throughout the remaining 15 waking hours of the day?

Closing Thoughts

  • Pre- and post-training nutrition is important, so do it! I don't really care what it is, just have SOMETHING.
  • Water makes up roughly 70-80% of your muscle cell composition. So don't forget hydration!
  • Supplements can be fantastic for convenience. For example, while traveling, it's much easier to fill a few ziplock bags with Surge Recoveryrather than bringing your blender with you.
  • Yes, the "training window" is important for getting in a quality shake/meal, but it will never outshine dialing in your nutrition during the other 15 hours of the day.
  • This post is geared toward the majority of the population. Yes, I realize there are outliers (bodybuilders two weeks out from a competition, for example) that will lead to exceptions for my recommendations. For the sake of brevity I omitted those here.
  • Keep it simple. Ingest something with some sugar, protein, and even some healthy fats and make sure that it sits well with your stomach.
  • From what I can judge from recent research, consuming fats will not significantly slow the absorption of other nutrients (thus hindering recovery) in the grand scheme of things.
  • For athletes partaking in multiple training sessions a day: Yes, get in your post-training shakes, FOR THE LOVE!!
  • Focus on quality training sessions, getting a full night's sleep, and reducing stress in your schedule. This will trump the potential benefits any workout shake.

*Although, for the record, I totally could. **I knew a guy that literally spent so much time and thought mixing and matching his chemicals for his bazillion shaker bottles, each and every day (while rarely focusing on his actual workouts), that we nicknamed him "Chemistry Set."

Pink Slime in School Lunch

This is important:

"Pink slime" is the term used for a mixture of beef scraps and connective tissue (formerly used only for pet food and rendering) that is treated with ammonia hydroxide to remove pathogens like salmonella and E coli. These so-called "Lean Beef Trimmings," are produced by Beef Products, Inc.

Two former government microbiologists claim that, for political reasons, pink slime was approved for human consumption by USDA over serious safety concerns.  (http://bit.ly/waMMni)

Government and industry records obtained by The New York Times in 2009 showed that "in testing for the school lunch program, E. coli and salmonella pathogens have been found dozens of times in Beef Products meat, challenging claims by the company and the U.S.D.A. about the effectiveness of the treatment. Since 2005, E. coli has been found 3 times and salmonella 48 times, including back-to-back incidents in August in which two 27,000-pound batches were found to be contaminated. The meat was caught before reaching lunch-rooms trays."

Even apart from safety concerns, it is simply wrong to feed our children connective tissues and beef scraps that were, in the past, destined for use in pet food and rendering and were not considered fit for human consumption.

Due to public outcry, fast food giants like McDonald's and Burger King have stopped using pink slime in their food.  But the federal government continues to allow its use in school food and has just authorized the purchase of ground beef which collectively contains an additional 7 million pounds of pink slime for consumption by our nation's children.

Tell the USDA to STOP the use of ground beef containing pink slime in the National School Lunch Program!

Another Sugary Experience

I have to expand on a portion of my post on StrongGirlsWin.com from yesterday: the 3-Hour Glucose Tolerance Test. So, the test is screening for Gestational Diabetes and you only have to take this version if you fail the 1-Hour Tolerance Test (which I did).

There are, of course, strict rules to follow to keep the test valid:

  1. Eat a diet containing at least 150g of carbohydrates per day for 3 days prior to testing.
  2. Fast for 8-hours before consuming glucose solution.
  3. Drink solution containing 100g of glucose within 5-minutes. Think throwing back about 4 shots in 5-minutes… maybe not the best idea.

Then you sit for 3-hours that are interspersed with blood drawing every hour.

Doesn’t sound too bad does it?

Well, for me, this is about as bad as it gets in terms of medical testing. I have strong dislike for fasting, having my blood drawn, being forced to drink huge amounts of sugar, and sitting still for long periods of time. I’m not trying to exaggerate or be funny, I really don’t like any of those things.

In fact, I almost didn’t get the test done at all. After all, I’ve “been there, done that” with my first pregnancy. So, why should I put myself through this hellish experience again?

Aside from simply “getting over myself” and acting like an adult, I pulled up some research to educate myself on the risk factors associated with babies who are born to women with gestational diabetes and decided I did, in fact, need to get over myself.

A couple of the most notable risk factors for the child that I didn’t know include: increased likelihood of becoming diabetic at some point in their future life and falling into a coma if the doctors don’t know they need to monitor the newborn’s blood sugar levels. Those were the two points that resonated with me.

Well, anyway, this got me thinking about how absurd it is to consume so much sugar in one sitting, much less in one single day. But, that’s exactly what people do ALL the time!

Here are a number of popular beverages you or a loved one probably consumes regularly. All have around 100g of sugar:

You may think I'm being a bit dramatic about this whole thing. It's just a standard test, after all. But diabetes has a history in my family and I recognize my body's own regulation of its blood sugar levels as a natural challenge - pregnant or not. I've actively been trying to provide myself the best quality foods for about 10 years now and the idea of failing any sort of glucose test is frightening for me!

The good news is I passed my second test and the doctor assured me failing the first version is NOT a sign of things to come... not sure if I totally believe her. I think I'll just keep my head down, focused on continuing to consume high-quality whole foods and will have to enjoy Shamrock Shake commercials instead of indulging in the real thing:

Reducing Dietary Salt

I've never been one to worry much about my salt intake, but for this pregnancy I made the decision to really crack down on the added sodium in my diet. Why? Well, two reasons:

1. When pregnant with my daughter, I found that often my blood pressure was very low (this is usual for me). But, about 35% of the time it would inexplicably sky-rocket to a borderline high area. I don't know whether it was stress, anxiety, diet, or weight gain that caused this problem.

2. I also had a tough time with swollen feet/ankles by the last trimester of pregnancy 1, so I'll pretty much do anything to avoid that again.

Something to check out and consider: This morning Fooducate posted a blog called 9 Ways to Reduce Your Salt Intake.

I'm only just now reaching my third trimester of this pregnancy, so I don't know if my approach will be effective for the swelling. But, I do know that my blood pressure readings have been quite a bit more consistent and reasonable up to this point.
