How Chronic, Prolonged Sitting Impacts Your Body – and What to Do About It

Last week, over the course of two days, I made the long drive from Hudson, MA to Jupiter, FL. Suffice it to say that all those hours in the car gave me a newfound appreciation (or distaste?) for just how hard sitting is on the body. As such, it was really timely when my friend Michael Mullin emailed along this guest post on the subject. Enjoy! -EC

Disclaimer:

In this article, the author describes a fictional scenario in order to demonstrate a point related to the degree of information and misinformation there is in the layman and professional literature. It is in no way an attempt to create alarm that these facts apply to every person and every situation. While this article is not scientifically based, the published references are meant as an example of what some studies have found of the impact prolonged sitting and being in a stressful environment has on the body. Please read this article with the intent with which it was written—to provide concrete tools to use if you have to sit for extended periods of time.

I would like to have you read the scenario below and let me know if you would want this job.

“Congratulations on being selected for the position of top minion here at Do Everything Against Design, Inc. (DEAD).  Our company is a prestigious purveyors of thneeds—and a thneed is a thing that everyone needs (5). We pride ourselves on our commitment to being on the cutting edge of business and we use only the best, most up-to-date information possible to dictate how we run our business.”

“Let me start off by saying that this job will provide all kinds of potential benefits. It is up to you to decide how committed you are. The potentials are endless—overuse injury, chronic pain, depression, increased alcohol use, drug or medication use, cancer, increased general mortality, even bullying—that’s right, just like when you were a kid—are all very real possibilities here at DEAD, Inc.”

“So first thing we will do is get you set up with your work area and station. Here is your cubicle which studies have shown are detrimental to not only work life but also your personal life (1). And here is your ergonomically correct chair so that your body doesn’t have to move, because research has shown that sitting 90% of your day, will almost double your risk of developing neck pain (2). We are also well aware of the fact that this increased time sitting will ultimately yield to a higher mortality rate for you (3), and make you feel generally crummy, but we are willing to take your chances. In fact, don’t even bother trying to counter all this sitting with exercise, because it will increase your risk for certain cancers by up to 66% regardless of how active you are when not sitting! (4)”

“However, placing this degree of stress and strain on your body is mainly so that we can reduce the organization’s costs and increase productivity (5), which is what is most important to us. Because ‘business is business and business must grow, regardless of crummies in tummies you know’ (6). And you do want to be a team player, don’t you?”

“In fact if you do end up having any physical problems, there is a greater than 63% chance that it is actually due to work (7). And if it isn’t from sitting too much (8), then it is due to the psychological stress that this position places on you. Heck, it might even be due to me and the stress I place on you! I will give you an 80% chance that our workplace stress will be the most important factor you will have to deal with here (9).”

“We have also found that this job can also really give you a great chance on becoming an alcoholic or binge drinker (10), so you have that going for you as well.”

“If stress does become greater than you can learn how to cope with, which is apparently one important part of your employment here (11), then rest assured that we don’t really have a plan in place, because 80% of facilities do not have formal programs in place to deal with workplace stress, and of those that do, only about 14% say it is effective (12). Since that’s what the research suggests, then I mean, how important can establishing a plan be?”

“The single greatest thing about this whole situation is that I will actually pay you to let me break you down, little by little, bit by bit, until you feel beaten and broken. Don’t you see? It’s a win-win situation for both of us here at DEAD, Inc!”

I decided to title this article differently from my original title, “Your Employer Is Trying to Kill You” because I thought it might be a little less inflammatory. But, if you think about it, if data were used to truly guide what we should be doing, than many jobs where employees have to sit the better part of the day are truly a form of abuse. OSHA should be having a field day with these kinds of stats!

This is not about trying to bash many of the companies that have these incredibly sedentary work environments, though. Moreover, it's also not about the fact that I disagree with how our ergonomic evaluations and standards currently are. This is more about trying to create a "Movement/Movement."

Michael Mullin

Our bodies are designed for movement. Period. Our brains are designed for processing and trying to create efficiency so that we can process more. Now that’s pretty smart, however, highly detrimental when it comes to the importance of movement. Because if we continue to listen to what our brain is telling many of us, then it will constantly suggest that we just continue to sit to conserve energy.

So what to do for those of us who have to sit regularly during the day?

  • Get up regularly, even if it means setting a timer at your desk to walk down the hall a couple of times. Not only good for the body, but also good for the brain.
  • Stand every time the phone rings in your office, even if it means you have to sit back down to do something at your computer for the call.
  • Every hour, independent of getting up for regular walks:
    • Sit at the front edge of the chair, hands resting on thighs and body in a relaxed position—not too slouched or sitting up too straight. Take a slow breath in through your nose, feeling your ribs expand circumferentially. Then slowly, fully exhale as if you are sighing out and exhale more than you typically would, without forcing or straining. Inhale on a 3-4 count, exhale on a 6-8 count, then pause for a couple of seconds. Re-inhale and repeat for 4-5 breaths.
    • Staying in this position at the front edge of the chair, reach one arm forward, alternating between sides, allowing your trunk and torso to rotate as well. Your hips and pelvis should also shift such that your thighs are alternately sliding forward and back. Perform 10 times on each side, slowly and deliberately and while taking slow, full breaths.
  • Consider using your chair differently, depending on the task:
    • When doing work on the computer, sit with the lowest part of your low back (i.e. sacrum) against the seat back, but don’t lean your upper body back. This will give the base of your spine some support, but also allow for good trunk muscle activity as well as proper thoracic circumferential breathing.
    • When doing general work such as going through papers, moving things around your desk, filing, etc., sit forward on your chair so that you are more at the edge of the chair. This will allow your legs to take more load and your trunk muscles better able to aid in support, reaching and rotating tasks.
    • When reading items or reviewing paperwork, recline back with full back contact to give your muscles, joints and discs a rest. Make sure to hold the items up at roughly shoulder height—even if you support your arms on armrests or desk.

Remember, chairs and sitting is something that WE as humans created and the current norm is in no way optimal. We were not put on this planet to sit on chairs, and in particular not ones which shut our system off and limit our movement and ability to breathe normally. Until organizations and the general mindset changes to balance work requirements, work efficiency and human health, then we will be constantly be dealing with companies such as DEAD, Inc.

How to Coach the Deadlift Set-up for Strength and Safety

I recently was asked how I approach breathing at the start of a deadlift, and - realizing that it was just the tip of the iceberg with respect to the deadlift set-up - I decided I'd post this presentation on the topic. This four-minute video is an excerpt from my longer presentation, 15 Things I've Learned about the Deadlift, which is a component of our Functional Stability Training of the Lower Body resource.

How Strength and Mobility Impact the Pitching Stride

Today's guest post comes from Cressey Sports Performance Pitching Coordinator, Matt Blake. Matt is a key part of the Elite Baseball Mentorships team. Enjoy! -EC

In today’s video, we’re going to be discussing stride dynamics in the high-level throw. In order to do that, we’re going to use Zach Greinke as our pro model and then show a few other amateur variations, while going into some detail on how strength and mobility play into the equation for developing this powerful stride.

This is important to understand because a lot of the other qualities we look for in a high-level throw – such as achieving efficient “extension” at release, repeating the delivery, and executing our deceleration pattern consistently in an effort to reduce stress – all rely on having a stable stride pattern. In order to understand how this works, let’s take a look at some of the components that make up Greinke’s stride:

As you can see, one of the defining features of Greinke’s stride is the efficient action of his back leg and hip directing the pelvis down the target line early to set the direction and momentum for the stride. The way this is achieved is often overlooked and ultimately results in “offline” or unstable landings.

If you’ll notice the move that Greinke is making here is a posterior weight shift where he actually pushes his hips back in the delivery by hinging at the hip and not drifting his knee forward over his toes like most amateurs do. By engaging his posterior chain in this manner and not relying simply on his front leg to swing him into landing, he’s able to create a more balanced stride phase that unfolds in a more rhythmic manner, using the lead leg as a counter-balance to the delivery and not the primary power source.

For those familiar with the strength & conditioning world, I typically like to relate it to the initial movement of a one-legged squat to feel the glute and hamstring engagement and then a lateral lunge to stay engaged in the adductors for control of the pelvis. The lead leg action is ultimately just a relaxed extension to counter the posterior weight shift and then a swivel in the hip socket to align the foot for landing.

Eric-Cressey-Plate-Slide-576

The effect of engaging the rear leg’s posterior chain allows us to create both extension and rotation out of the back-side, which is important for maintaining the direction of our force into the ground at landing. If we can’t control the force of our action into the ground, we won’t be able to stabilize our landing appropriately, which has ramifications up the chain into our pelvis positioning, core stability and ultimately into our hand positioning on the ball at release.

If we’re trying to create a level of “extension” at release and maintain our leverage on the ball to throw it with angle, we need to take ownership of our pelvis positioning. If we don’t actively control the pelvis movement into landing, we’re going to have a hard time centering the head of the lead leg in the hip socket, and in turn, accepting the ground reaction force that we’re trying to create. This happens when we lose the tension of our back hip too early, because we swung our lead leg out as the power source and “chased it” into landing. This means we won’t have control of the pelvis upon landing and we’ll be unable to properly pressurize the front leg to keep leverage in the delivery.

This pelvis leverage is essential in making sure we can keep our core stable and allow it to translate the thoracic region forward, instead of rely on it to create motion, which isn’t the primary role of the lumbar region. We want the “core” to simply transfer the energy we created from the lower half efficiently. If we can do that, we allow ourselves to accelerate on a longer line to release, because our path of deceleration is set up to be fully accepted on the front hip’s internal rotation and flexion. If the pelvis is too flat, and relies purely on rotation and not flexion, our line of deceleration becomes much shorter and forces us to handle more of the stress in our throwing arm, which isn’t ideal.

A good example of how both length in the adductors and strength in the posterior chain helped an athlete achieve a more athletic and powerful stride can be seen here. The first clip is a video of a 17 yr old LHP, who was 6’4” 180lbs, and 82-84 at the time of the video:

Notice how his stride pattern is very limited not only in his length toward home, but in its inefficient direction and its ability to allow for a full finish to protect the arm. As you can see, this athlete struggled to get a posterior weight shift out of his gather position, drifted into a closed stride position, and then had too flat of a pelvis position to achieve a proper flexed hip position. As a result, he runs out of lateral rotation in the lead hip and the finish buckles on him. This could be a result of many things, including limited adductor mobility, poor single leg stability, weakness of the anterior or rotary core, etc. Candidly, though, you usually see all these things in untrained pitchers!

Fortunately, this same athlete took it upon himself to devote some quality time to making himself a better athlete, getting stronger, and gaining awareness for the movements the high level delivery was asking of him – and he’s now turned himself into a legitimate prospect. In this more recent video, the athlete is 20yrs old now, 6’5” 215lbs, and 88-91mph, topping at 92mph:

By no means is this athlete a finished product, but you can see where the added strength, mobility, and movement awareness allows him to get into a deeper hip-hinge position, ride out of the stride longer, and certainly take the finish deeper to allow for a longer line of deceleration. The next step for this athlete will be continuing to work on his single-leg stability, as you can see a slight wobble in the landing and a touch of misdirection, but certainly leaps and bounds ahead of where he was three years prior.

To give you an example of where this stride pattern can go, here is an example of one of our more accomplished athletes, Tyler Beede, who was the 14th overall pick in this year's draft and had one of the best amateur stride patterns I’ve seen:

From time to time this athlete will struggle with slight misdirection and postural control, but his ability to pitch 92-96mph with above average off-speed offerings is a testament to the balance and power in the lower half of his delivery.

At the end of the day, everyone is going to present with different levels of mobility, stability and coordination, so you certainly have to leave room in your model to account for individual variance. However, these athletes are good examples of how properly maintained mobility and stability can tie into the high-level delivery to make you a more powerful and durable pitcher in the long run.

Looking for more video analysis and training insights like this? I'd encourage you to sign up for one of our upcoming Elite Baseball Mentorships. We have events in both October and November, and you won't find a more intensive baseball educational course.
