Train to Failure or Train to Success? Part I

Standard

Nike says “Just Do It.”  The people in Gatorade commercials look like they’ve worked within an inch of their lives.  The Crossfit mascot is a character called Pukie the Clown.  “I want you to push me,” is something trainers hear all the time from clients and potential clients.  Classes known as “boot camps” are have been very popular the past few years, complete with yelling, hollering and foot-dragging exhaustion.  We want to “test our limits.”  What’s the observation here?  If some exercise is good for us–then a whole helluva lot must be extra super awesome!!! That’s how we do it in America right?  Some = Good.  LOTS = GREAT!!!  This type of thinking sells but does it actually result in greater physical ability?

I’m reading a great book in Pavel Tsatsouline’s Power to the People!.  It’s very much making me rethink the way I train my clients as well as myself.  The book is all about heavy strength training–not bodybuilding mind you.  We’re talking strength not size.  Interestingly, I’ve noticed some parallels to advice given in the classic running book by Tim Noakes, Lore of Running.  How could it be that training for the expression of brief maximal strength might share anything at all with endurance running?

Key points of advice given in both texts amount to this: Train to the point of success, not to exhaustive failure.  As Noakes puts it:

The single most important reason most runners are prone to overtraining is, I believe, that we lack the ability to make an objective assessment of our ultimate performance capabilities.  We simply will not accept that we are mortal and that we have a built-in performance range beyond which training and other interventions cannot take us.  We believe that the harder we train, the faster we will run, and we ignore the evidence that indicates that this is blatantly untrue.  Thus we train harder and run worse.  And then, in the ultimate act of stupidity, we interpret our poor races as an indication that we have undertrained.  Consequently we go out and train even harder.

Similarly, Pavel states:

“From Eugene Sandow to Yuri Vlasov, the strongest men and women in the world have never trained to failure!  Cut the ‘do or die’ rhetoric, take a long hard look at yourself, and tell me what are your odds of becoming another exception?  If ‘training to failure and beyond’ is so hot, how come your bench has been stuck at 185 lbs. since Arnold’s first movie?”

Also from Pavel:

“Ed Coan squats 875 lbs. x 3 and calls it a day although he knows he could’ve fived that weight.  Heavy training not to failure sure worked for Coan who has set nearly eighty world records.”

Is this surprising information?  Maybe not if we consider the nervous system and the SAID (Specific Adaptation to Imposed Demand) principle.  Simply stated, our nervous system always adapts to exactly what we ask of it. 

If we swim a lot then we tend to be able to swim.  If we ride a bike frequently then we adapt to bike riding.  If we lift heavy weights then we tend to get stronger.  (Also, if we sit hunched over a desk for enough of our life, we tend to be hunched.)  To the point of this post, if we train the nervous system to move our bodies successfully in clean, efficient form be it running, lifting, rock climbing, getting groceries–whatever–then we are training to succeed.  If however we spend enough time going to failure–that is to the point where our technique becomes sloppy and inefficient–then the nervous system says, “You want to practice doing this exercise in poor, sloppy form?  Okay.  I’ll adapt to that.”  Thus we develop poor, sloppy movement patterns.  The result of prolonged poor movement may be tendonitis/tendonosis, bursitis, arthritis–all sorts of itis-es: pain, in other words.

So what does success feel like?  We’ll find out in Part II of this post.

Z-Health for Toe Pain

Standard

This will be brief.  I’m enormously excited over the results I’ve been getting from my Z-Health work.  My back pain, Achilles pain and shoulder pain have all improved quite dramatically over the past few weeks.  (I also added 70 lbs. to my deadlift in one fell swoop!)  Yesterday it was my wife’s chance to be surprised by Z-Health.

My wife is a triathlete who’s had intermittent big toe pain in her left foot over the past several months.  It comes and goes and it never had a clear-cut cause.  Yesterday, after visiting with Jason Wood in Lakewood, CO I went home and had my wife go through some Z-Health R-Phase drills.  One of the Z-Health concepts deals with opposing joints.  That means since my wife’s toe pain was in her left foot, I had her go through drills with her right hand and thumb.    The result?  No toe pain whatsoever!  As she gaped in bewilderment, she drove her foot into the ground and wiggled her foot all over and she could not replicate the pain.  The toe pain returned this morning during a dog walk, she went through the drills again for a few moments and again the pain was gone.  (As an aside, the toe pain comes on most notably in a pair of hiking boots.  Perhaps the shoe is interfering with the natural function of her foot, as I’ve discussed here.)  Pretty cool stuff this Z-Health.

I’ll be taking the R-Phase certification in March and April of this year and I’m extremely excited.  I’ve just barely begun to scratch the surface with this exercise protocol and I expect to see more and more dramatic results.  If you’re a fellow personal trainer, a chiropractor, physical therapist or anyone else involved in the health & fitness  business, I highly suggest you look into Z-Health for everything from injury treatment to increasing sports performance.  If you’re an athlete or just an everyday fitness fan who’s either in pain or not performing as well as you’d like, you would do well to seek out a Z-Health trainer for help and advice.

Recovery & Restoration Methods for Endurance Athletes Part II: Cold Water Immersion

Standard
Time to relax!

Time to relax!

Post-workout nutrition was the focus of the last post.  Adequate intake of water, protein and simple carbohydrates is vital for repairing the body and preparing for subsequent endurance workouts.  We can add to the recovery strategy the use of cold water immersion.

“Cold water immersion resulted in significantly lower muscle soreness ratings; reduced inflammatory response and consequent muscle damage; and better repeat sprint ability and leg strength,” Jeremy Ingram, physiotherapist, in the J Sci Med Sport. 2009 May;12(3):417-21.

Injury treatment has long featured the application of ice to strains, sprains, bruises and other injuries where swelling is present.  Strenuous or long bouts of exercise can damage muscle cells thus resulting in conditions similar to injury such as low-grade swelling, pain, and nervous system disruption.  Studies by the Journal of Science and Medicine in Sport, the European Journal of Applied Physiology, the Journal of Sports Sciences,  show cold water bathing was well as hot/cold contrast bathing reduces these symptoms and helps speed recovery.

Protocols for cold water immersion and hot/cold contrast bathing are discussed here and here.  (The idea behind the contrast method is to create a pumping action in the capillaries to speed blood flow and thus increase the recovery process) Peak Performance Online offers this free download titled How to ensure a speedy recovery from exercise.  (Peak Performance Online features many free downloads on a wide variety of sporting topics.  Definitely pay them a visit if you want to read a lot more.)

The basic protocols for cold water and hot/cold contrast recovery vary but are fairly similar.  Here are two examples:

Cold Water Immersion
If you are going to try cool or cold water immersion after exercise, don’t overdo it. Ten minutes immersed in 50-60 degree Farenheit water should be enough time to get the benefit and avoid the risks. Because cold can make muscles tense and stiff, it’s a good idea to fully warm up about 30 to 60 minutes later with a warm shower or a hot drink.

Contrast Water Therapy (Hot-Cold Bath)
If you prefer alternating hot and cold baths, the most common method includes one minute in a cold tub (50-60 degrees Farenheit) and two minutes a hot tub (about 99-104 degrees Farenheit), repeated about three times.

My own cold-water recovery has employed two simple methods.  First, when I lived in Virginia I had access to a swimming pool in the summer.  Following a ride or run in the hot weather, I got in the pool, preferably in a shady area, and relaxed.  This past summer in Colorado, I filled my bathtub with cold water so that my legs were covered and I dumped in a small amount of ice.  It was cold but not painfully so.  I sat and drank Recoverite and an energy drink with caffeine.  I found the results very beneficial.

Speaking of caffeine, I’ll discuss that in Part III.

NEAT and the Benefits of Hunger: Part III

Standard

In Part I discussed Non-Exercise Activity Thermogenesis (NEAT).  The biochemistry of hunger and the possible benefits of hunger were the issues in Part II.  I ended by posing the question of whether or not consuming several small meals per day was more or less conducive to losing weight than the popular admonition to eat up to six small meals per day.  It seems the verdict is very much out.  The answer is: It depends…

To start with, here’s an article by registered dietitian Kristine Clark writing for the IDEA Health & Fitness Association.  Clark first offers wise observations on the exact nature of hunger and satiety.  Hunger being the main reason we should eat at all and satiety being the signal to stop.  She writes,

“‘Unfortunately, many people are out of touch with the feeling of satiety.”  Marion Nestle—researcher, author and professor of nutrition at New York University—says, ‘You can’t teach satiety.  People have to learn it themselves.’  The bottom line is that recognition of both hunger and satiety is key to appropriate eating.

Anyone seeking weight loss must take that statement to heart.

Clark then refers to the research from the 1960s and ’70s that associated several small meals with a leaner physique.  I won’t go into the details of the studies (references are found at the end of Clark’s article) but both studies show weaknesses worth considering.  The small sample sizes and the use of a 24-hr diet recall interview in one study make me question to what degree we should hold to the implications of these studies.  I’m not the only one thinking this.  For further reading on the strength or lack thereof of nutritional studies, look here and here.  (And remember these sorts of weaknesses the next time a news anchor tells you that some study shows This causes That. Odds are the cause and effect aren’t that strongly linked.)

Most importantly, Clark interviews Dr. Barbara Rolls of the Penn St. Nutritional Science Department.  Essentially she says that meal frequency isn’t the key issue–It’s how much you eat!

“As long as people hold their calorie intake constant—as long as they eat less than what they normally eat, whether in six or three increments —they will lose weight, regardless of the frequency.”
– Barbara Rolls, PhD

So it should be obvious.  The key issue is energy intake vs. energy expenditure.  This is no revelation.  Whether it’s three, four, five or six meals per day, if we eat too much then we get fat.  (I’ll add my own opinion to this equation and say that the quality and the nature of our food–real food vs. food-like substances–is of tremendous importance to physique goals as well.)

I’m surprised by the fairly weak correlation between the several-small-meals strategy and successful weight loss.  I’ve been saying this to clients as if it were a settled subject.  I will say though I believe the first time I ever heard the suggestion to eat many times throughout the day was as advice to bodybuilders who were trying to gain weight, not lose it.  Bodybuilders need the raw materials to add body mass so loading up on food several times a day is about the only way to do it.  In contrast, the general public doesn’t have that need, and it stands to reason that by many among us may easily eat too much if we’re eating up to six times a day.

No second helping for me, thanks.

No second helping for me, thanks.

Finally, I didn’t know exactly where to put this, but General Stanley McChrystal, the current commander of U.S. forces in Afghanistan, eats one meal per day!  This man is a dedicated runner with a Special Forces background.  One meal per day…

NEAT and the Benefits of Hunger: Part II

Standard

Previously we looked at the deliterious health effects of our seated, sedentary modern lifestyle; and we saw remarkable value of NEAT, or Non-Exercise Activity Thermogenesis.  Essentially, sitting a lot correlates to early death while moving around a lot makes you healthy–even if this movement isn’t what you might call “exercise.”

Part II of the discussion revolves around the article Movement comes with appetite, found on Science Daily.  We’re told of findings by a Swiss research team, whose study is found in the journal Nature.  (The full study can be accessed here for a fee.)  The science here is fairly complicated so I’m going to try and avoid the overly complex details.  Essentially, the star of the study is a molecule found in the liver and hypothalmus called Foxa2.  Foxa2 is found in humans and other animals.  Here we go with an attempt at explaining why Foxa2 is important.

Foxa2 found in the liver affects fat burning.  It’s also found in the hypothalmus which affects daily rhythm, sleep, intake of food and sexual behavior.  Researchers also observed that Foxa2 helps form two proteins (MCH and orexin) which trigger both the intake of food and spontaneous movement.  Foxa2 is blocked by insulin which is released when we eat.  In a fasted state–between meals for instance–insulin is absent and Foxa2 is active.  Thus animals tend to be more active while hungry.

If mammals are hungry, they are more alert and physically active. In short, they hunt and look for food. “If you watch a cat or a dog before feeding it, you can see this very clearly,” Markus Stoffel, a professor from the Institute of Molecular Systems Biology at ETH Zurich.

Researchers found a Foxa2 disorder in obese mice.  High levels of insulin blunted Foxa2 which in turn reduced production of the two proteins that triggered hunger and movement.  To prove this, the researchers bred mice with ultra-active Foxa2 production and the result were mice with high production of the two proteins.  These mice lost fatty tissue and formed larger muscles. Their sugar and fat metabolism increased considerably.

The practical suggestion from Stoffel is that we should be hungry sometimes.  “The body needs fasting periods to stay healthy.”  Hunger promotes movement and thus all the benefits we expect from an active lifestyle.  Both the study’s evidence and the suggestions from this researcher are contrary to much of the popular nutrition advice.

The suggestion that one should eat small frequent meals throughout the day (aka grazing) is standard advice found on almost any list (look here, here, here, here and here for starters) of healthy eating tips.  I’ve told clients this many times and I’ve followed this bit of common knowledge for years.  The reasoning behind the several-small-meals tactic is 1) eating throughout the day keeps the metabolism up, and 2) if we become too hungry then we tend to overeat at mealtime.  Is it possible we’ve been doing it wrong?  Could three meals a day in fact make us leaner and healthier?  I think the answer to that question is the same answer  to most questions: It depends.  I’ll discuss it more in Part III.

The Dangers of Sitting; NEAT and the Benefits of Hunger: Part I

Standard

The longer you spend sitting each day, the more likely you are to die an early death — no matter how fit you are.

Right around Thanksgiving I discussed some of the science behind obesity and eating.  Now, the tremors of holiday gorging have started, and an eruption of Christmas binging is close at hand.  It’s cold outside and here in Colorado we’ve got several inches of snow on the ground.  This seems the ideal backdrop to look at obesity again, this time with an eye toward energy expenditure.

Two articles present slightly different information on the same general issue, that is the relationship between movement and obesity.  I’ll discuss the first article here and the second in part II of this post.  Your Body’s big enemy?  You’re sitting on it comes from MSNBC.com.  The article has two main topics.  First, we’re told of the consequences of our modern, mostly seated lifestyle.  We sit at our jobs.  We sit getting to our jobs.  We sit for entertainment.  And our many electronic tools allow us to live our lives while expending very little energy, especially when compared to the bulk of human history which featured far more physical labor than we currently experience.  Specifically we’re told about the biochemistry of too much sitting:

“When you sit for an extended period of time, your body starts to shut down at the metabolic level, says Marc Hamilton, Ph.D., associate professor of biomedical sciences at the University of Missouri. When muscles — especially the big ones meant for movement, like those in your legs — are immobile, your circulation slows and you burn fewer calories. Key flab-burning enzymes responsible for breaking down triglycerides (a type of fat) simply start switching off. Sit for a full day and those fat burners plummet by 50 percent, Levine says.”

Sitting increases our risk of diabetes and heart disease and it may even increase our risk for depression.  It’s also none too good for our spinal health and posture.  A bottom-line assessment of sitting was observed by Canadian researchers: The longer you spend sitting each day, the more likely you are to die an early death — no matter how fit you are.  (The article stated this finding but I’m not sure exactly where or by whom this research was done.)

The second topic is NEAT, or Non-Exercise Activity Thermogenesis.  (Read more on NEAT from the Mayo Clinic.)  Examples of NEAT include tapping our toes, gesturing with our hands while talking, doing house work or yard work, standing while working or any sort of fidgeting–even chewing gum.  According to Mayo Clinic research, NEAT has a big impact.  A study found that after 10 days, lean participants moved an average of 150 minutes more per day than overweight participants  That translates to 350 calories, or about one cheeseburger.  Take that out to one month and that’s 10, 500 calories (3 lbs. of fat).  In one year NEAT may burn up to 127, 750 calories or almost 37 lbs. of fat!

What can we do with this information?  Well it goes to a discussion I’ve had with many of my personal training clients who are trying to lose weight.  Find a way to move around somehow.  An hour or a half-hour a day in a gym doesn’t add up to much by the end of the week.  We’ve got to find ways to move around a lot more than that.  Your body needs to move throughout the day.  Here are some ideas:

  • Stand up while talking on the phone.
  • Set the meeting timer on your Microsoft Outlook (or similar e-mail system) for every half-hour with this message: GET UP.  WALK AROUND.
  • Use the stairs.  Avoid elevators and escalators.
  • Wash dishes by hand.
  • Quit looking for the parking space closest to the mall or grocery store entrance.  Park way back in the back and walk to the entrance.

The bottom line is this: Sitting is death by a thousand keystrokes.  Moving yourself about the planet under your own power has tremendous health benefits.  Your body doesn’t care if you do it in a gym or whether or not you call it “exercise.”

Alright, you’re done reading.  GET ON YOUR FEET AND GO DO SOMETHING!

A Little Bit on Stretching: Part II

Standard

So where are we?  We’ve covered the different flavors of stretching.  I now need to go back to something I said in Part I: No human movement is possible without stretching.  This is going to get a little more complicated before it gets simple–but I promise to give you information that you can actually use outside the game of Jeopordy!

Look at the stride--the STRIDE!--not the filthy habit.

Each time we move, we use energy stored in stretched muscles to drive our limb into movement.  When I take a step forward for instance, I hit the outer part of my heel and it rolls inward (calcaneal eversion).  The arch of my foot pronates a bit, and it pulls my calf muscles (soleus, gastrocnemius, posterior tibialis, among others) inward which takes my lower leg (tibia) inward into internal rotation.   At the same time, my body is moving forward over my ankle which creates dorsiflexion.   The tibial internal rotation also causes my knee to flex and internally rotate.   Once the knee moves in, it pulls on the IT band which is attached to my glute complex and now my glutes lengthen both forward and inward and my hip flexes–and if my hip is functioning properly it will move sideways into adduction in the direction of this leg that just took a forward stride.  So all these muscles have worked and stretched to keep my foot and leg from collapsing into the earth.  Now these muscles have all been turned on and with the energy stored inside them like stretched rubber bands they will propel me forward into my next stride.

Without going into every single action, the muscles and limbs of the opposite leg are contracting and creating extension, external rotation and abduction (though the adductors are stretching and slowing external rotation of the femur) at the hip, extension and external rotation at the knee, and plantarflexion and external rotation at the calf and ankle, and supination at the foot.

WOW!!!  Are you kidding me!!  What a lot of stuff!!  And that’s the story from just from the waist down!  All that and this lady can still manage to smoke a cigarette.  Did you notice how many muscles were stretched in this process, and in what directions?  Parts were moving forward, back, inward, outward and sideways.  As Gary Gray terms it, this is 3-D loading to exploding.

In all seriousness, this sequence of events must happen in order for our bodies to efficiently produce force and absorb shock.  Each stretch of each muscle in turn activates muscles up the line.  If this process is inhibited (could be due to injury, sitting too much, doing the same thing over and over and over, or who-knows-what) then we tend to get knee pain, back pain even shoulder or neck pain.

These movements aren’t just important for walking and running.  Proper movement in all three dimensions is vital for cyclists, skiers, dancers, even swimmers–even though their movement patterns are different from walkers and runners.

In Part III I’ll build on this whole process and show you an effective way to mobilize some important regions of the body via dynamic stretching.

Running in Groups

Standard

The Sept. 16 New York Times Personal Best column discusses the benefits of group running.  Several top runners and coaches are quoted as saying performance improves among athletes who train in groups.  Advocates of group training say that athletes train harder with a group compared to training alone.  Tim Nokes explains in Nokes’ Lore of Running that group training is a key component Kenyan runners—the best distance runners in the world.  Kevin Hanson, coach of the Hanson-Brooks Distance Project notes that runners in dominant distance running nations train in groups.

There’s actually scant scientific evidence that group training provides any benefit over training alone. (There are simply too many variables for which to account to do a valid scientific study.)  The experience of athletes and coaches however, and the results at the finish line gives strong suggestion that group training pays off.

Be careful though.  Group training tends to be more intense.  Too much intensity may lead to injuries such as shin splints, knee pain, or Achilles tendon irritation.  Intense training must be balanced with appropriate rest and recovery.

The article has some interesting information but I’m also a little confused about certain parts.  Both Dathan Ritzenhein and Kara Goucher referred to injuries they had sustained prior to running with a group.  The article seems to imply that they resolved their injuries simply by training in a group.  How did that happen?  The article also mentions the need for recovery and the possibility of training too hard due to the competitive dynamics of group training.  So what’s at work here?  Group training can help.  It might also hinder, but the issue of the runners’ injuries is never explained.  I’d like to see exactly how Ritzenhein and Goucher overcame their injuries.  Did running in a group have anything to do with the process?

Anyhow, here’s a list of Denver area running groups:
