How Long Does Whey Protein Last For? We Take A Look At The Shelf Life of That Cannister of Whey Protein

Dear Fitness Nerd,

I have a quick question about the shelf life of whey protein powder.  My ex boyfriend left a 5lb tub of Optimum Nutrition 100% whey protein powder in our apartment, but I can’t seem to find an expiration date on it. We’ve been broke up for about a year, so I know it’s at least 12 months old. It still has the seal on it, so I think he may have bought it right before we split. Is it safe to use? And do you have any idea how long it will keep?  Thanks! –  Tasha (Las Vegas, NV)

Delayed Onset Muscle Soreness (DOMS) | Preventing & Treating DOMS

Muscle soreness after exercise can put a real kink in your training. Find out what DOMS is, how to prevent it and what you can do to ease delayed onset muscle soreness if you get it.

Nearly anyone who works out regularly has experienced sore muscles after exercise. Sometimes you’ll feel it later that night, or the next morning … and in some cases, you may actually think you’re out-of-the-woods, only to wake up two days later with stiff, tender muscles that feel as tight as rubber bands.

It’s known as Delayed Onset Muscle Soreness (also called “DOMS”), and it’s both loved and reviled by exercise fanatics. Loved, because many people view DOMS as a sign that yesterday’s workout was effective, but hated at the same time because in severe cases, Delayed Onset Muscle Soreness can prevent you from comfortably hitting the gym again.

And in the case of calf muscle soreness — which plagues runners as often as weight lifters — it can literally make going down a flight stairs in the morning a three minute ordeal.

Symptoms of Delayed Onset Muscle Soreness

You probably have a case of Delayed Onset Muscle Soreness if you experience any of the following symptoms:

• Muscle tenderness
• Muscle soreness
• Stiffness
• Swelling
• Pain
• Loss of mobility or reduced range of motion
• Muscle tenderness, including when the muscle belly is pressed with the fingers
• Loss of strength
• Acute muscle twitches or spams

The extent and duration of these symptoms may vary from person-to-person and are largely dependent on the amount of resistance — especially eccentric resistance — placed on the muscles during exercise.

Bodybuilding Supplements: Do They Really Work? | Ask The Fitness Nerd

Do bodybuilding supplements really work, or are they just a waste of good money? The Fitness Nerd dissects body building supplements.

Dear Fitness Nerd,

I have a question: 

I’m 41 years old, and workout 5 days a week. I use a lot of bodybuilding supplements and spend a lot of money on them.

Unfortunately, I’m not gaining muscle like I want.

Currently, I take Masstech protein 2x a day. But I’ve also tried  Anabolic Pump, NoXplode, SuperPump 250, Universal Animal Stak, Size One, and Vitrix. But I don’t see many results.  Am I  doing something wrong? Can you help me on it? Thanks — Gleidson

Thanks for the question Gleidson.

I’m afraid that what you just discovered is probably discovered every day by countless bodybuilders and fitness buffs who are hoping to get an edge at the gym by downing expensive shakes, powders and pills.

Just browse the myriad of bodybuilding supplement discussion boards out there and you’ll find plenty of mixed opinions on whether supplements actually result in better performance at the gym. Some people swear by them, others shrug their shoulders and say all supplements give you is really expensive pee.

it’s often hard to sort out what really works, versus how many of the reported results are just the product of the placebo effect.   

While there are some supplements out that may be effective for helping more highly-conditioned trainees overcome plateaus, unfortunately, the majority of bodybuilding supplements and sports supplements marketed in fitness and bodybuilding magazines (and increasingly, online) are more sizzle than substance.

Bodybuilding Supplements: Big Demand, Big Promises … and Big Money

The first thing to realize is that bodybuilding supplements are a huge business.  

In 2007, sales of sports, diet and bodybuilding supplements — as well as energy/sports drinks and specialty diet foods —  topped $19.6 billion. That’s a lot of dough. So there is plenty of demand out there and lots of money to be had. With all that blood in the water, it’s bound to attract sharks, unfortunately.

The second thing to understand is that supplement manufacturers have figured out what nearly every other good direct marketer has discovered: That people want quick fixes. And they are capitalizing on that.

The idea that you can down a shaker of “clinically-formulated” protein powder, or the latest NOS booster and suddenly build that beach body or killer physique is very attractive. I mean, if it really worked, who wouldn’t do it?

And supplement manufacturers pull out all of the stops and use every clever trick in the book to make you really believe that they’ve cracked the code to “insane anabolic pumps” — whatever the hell that actually means.

Anatomy of a Bodybuilding Supplement Ad

There is a pretty standard formula to marketing bodybuilding and fitness supplements, whether those supplements promise to help you burn fat and get “ripped” or help you add pounds of lean mass fast.

Creatine and High Blood Pressure | Ask The Fitness Nerd

Can Creatine increase your blood pressure? The Fitness Nerd takes a closer look.

Hello Fitness Nerd,

I was inquiring into the possible connection between creatine use, and high blood pressure. 

I had been using creatine for about 4 weeks, not over-doing it, just a scoop a day after every workout.  Recently, I applied for a Police Force in my city, and when they took my blood pressure, they were somewhat shocked. 

Assuming I was nervous (which I wasn’t), they told me to take a few deeeeeeep breaths, in through your nose, out your mouth, yada yada yada…even calmer now, they took my blood pressure again, and they said, “it actually went up!” 

They were unable to let me do the fitness part of the test based on this, and I find it quite embarrassing since I don’t smoke, and I’m 5′ 10″ 175lbs.  I know we have a history of high blood pressure in our family (not something I’m going to put on my resume exactly!), but I think this is different. How can I feel calm, yet my bp says otherwise?  I went to a drug store last night, feeling pretty calm….my score was 133/69….heart rate 71….   From what I understand, that is unusual.  I took it a few minutes. later, it was 122/something…so I wasn’t sure if it went down, or it was just the machine giving inaccurate numbers…
Any help you’re willing to offer is appreciated. Brian.

Brian,

While the literature on creatine has found it generally safe for use among healthy adults, there are a number of reported side-effects associated with creatine supplementation. And guess what? One of them is high blood pressure.

So the elevated blood pressure that you saw at the Police Academy certainly could bethe result of creatine use.

But before I get into creatine and its possible impact on blood pressure, let’s talk a little bit about about creatine for my readers who may be new to it.

What Is Creatine?

Creatine is a naturally-occurring amino acid that is plentiful in skeletal tissue like muscle.  Fifty percent of the creatine in your body comes from diet (primarily from the consumption of red meat and poultry) and the remaining 50% is produced in the liver, kidney, and pancreas.

About one-third of the creatine in your body is bound-up with phosphate (also known as creatine phosphate or phosocreatine) and circulates freely in your body.

Your body essentially uses creatine to fuel high-intensity, short-duration exercise like weight lifting or sprinting.  Creatine phosphate plays a critical role in regenerating ATP, which is the process that the body uses to fuel muscle contraction, as well as protein production.

Creatine supplementation (typically via creatine monohydrate or one of its variations) basically increases the pool of available creatine phosphate, and in theory, reduces the amount of time required to regenerate the necessary levels of ATP to fuel an additional muscle contraction.

So people who supplement with creatine report being able to pump out an additional rep or two before fatiguing. It’s important to stress that creatine is not an anabolic steroid, but rather a natural vehicle for increasing the ability to perform work without fatiguing — which eventually may lead to increased muscle mass and athletic performance by performing more work, and progressively overloading the muscles.

Creatine also draws water into the muscle, which is one of the reasons that people often not only experience body weight gain during supplementation, but also observe an increase in the appearance of muscle volume. This may also be a mechanism for increasing blood pressure (since the body is retaining more water, which may impact blood volume — and thus, blood pressure.) However, a review of the scientific research cannot confirm this.

A lot of people who try creatine report that it makes them look larger, but not necessarily more “ripped.” This is because much of the initial gain comes from water retention in muscle tissue — and not from additional muscle mass. However, over time, the gains in additional work performed during weight training, can increase muscle growth and size (hypertrophy) that persist even after stopping creatine supplementation.
