- [Closing the Cardiac Care Loop: A Conversation with SIGMA Tactical Wellness Co-Founders Ben Stone, PhD, and Dr. Jon Sheinberg](https://iamsigma.com/closing-the-cardiac-care-loop-a-conversation/): In May 2025, TeleMed2U announced its acquisition of SIGMA Tactical Wellness, a healthcare enterprise dedicated to reducing cardiovascular risk among the law enforcement community. Today, we sit down with SIGMA co-founders, board-certified cardiologist Dr. Jon Sheinberg and Ben Stone, PhD, to discuss the origins of their risk assessment program to address the unmet cardiac health needs of police officers, and how SIGMA and TeleMed2U are now working together to close the care loop for these first responders moving forward. Thanks for joining us. Let’s start at the beginning—what problem were you trying to solve with SIGMA, and how did your […]
- [Let Me Tell You Why You Need Oxygen](https://iamsigma.com/let-me-tell-you-why-you-need-oxygen/): These little blog inputs that I have been seriously neglecting as of late I’ve noticed typically get one of two reviews: 1) It was great, but very condensed or 2) it was a mishmash of personal experience forcefully blended with enough technical jargon to make even a well-spoken British man nervous. So, I’ve decided to take a slightly different tack and instead focus on something that, not only everyone can understand, but also identify-with as well as putting things in terms that reduce the glazing sensation only brought about by that first ingredient of boredom- confusion.  On to business.Recently, I […]
- [The Benefits of VO2max Testing](https://iamsigma.com/the-benefits-of-vo2max-testing/): The elaborateness of VO2max testing is to some people a luxurious non-necessity reserved only for people with western European accents or for those who love to impress with the latest in technological revolution. That was indeed the case… back in 1971. Now, with modern methods of Vo2 (that’s short for “volume of consumed oxygen) max testing, it’s quite simple to keep regular tabs on your current oxygen consuming capabilities. However, the question remains in the back of the heads of many-a-skeptic as to how participating in this type of test is beneficial to their athletic proficiency. For one, the maximal […]
- [The Importance of Breathing](https://iamsigma.com/the-importance-of-breathing/): When given the choice between deep, rhythmic, more diaphragmatic breathing, or short rapid almost hyperventilatory breaths, it is almost instinctive to think that the aforementioned strategy is more advantageous than the latter. Certainly, one would assume that the quest for oxygen will be much more fruitful when your respiratory rate is more controlled, substantial, and relaxed. However, as of late, we have noticed an alarming trend in many of the clients that we have tested; and this trend becomes even more alarming when it is justified by misinformation…. At rest, respiratory rates (RR) are between 8 and 12 breaths per […]
- [Recovery Supplements](https://iamsigma.com/recovery-supplements/): Recently, while in my local bike shop I found myself paying some serious attention to my favorite category of products- Recovery supplements. As I became momentarily engaged with the sheer magnitude and overwhelming bulk of selection, I wondered how on earth someone without a doctorate or at least some education in nutrition and, from the looks of some of the ingredients, molecular biology would have any chance of selecting the product right for their individual needs. It was almost as if the designers were intending on confusing their targets with overly complex, but leading terminology carefully crafted in such a way […]
- [What to Eat](https://iamsigma.com/what-to-eat/): One of the most interesting attributes, I find, regarding cyclists, triathletes, and runners is that they spend thousands of dollars and countless hours in perfecting and fine-tuning their technique in hopes of capitalizing on the advantage come race day. While it is rather obvious that technology and training are quite important to compete, especially, in the upper echelons of endurance sport, what is not so obvious, and this is said out of shear personal observation, is the level of attention and degree of detail that is paid to nutrition while performing. While the following cliché is quite overplayed, it is […]
- [VO2max: Functional or Functionless?](https://iamsigma.com/vo2max-functional-or-functionless/): Since the advent of mainstream ventilatory data collection, VO2max, for some reason, has been the quintessential bit of information that makes an endurance athlete feel complete and whole. Granted, knowing that Lance Armstrong’s VO2max is “84” is both as interesting as it is humbling… that’s quite high, for the record. AND, I will admit that the most successful endurance athletes have historically had higher-than-normal VO2max values. However, just about everyone fails to understand that this metric is but one of many key indicators that consolidate the full spectrum of what most physiologists would consider a well-rounded athlete. They place an […]
- [Translating the Lingua Cycliste’ part I](https://iamsigma.com/translating-the-lingua-cycliste-part-i/): Cyclists are a different breed, I grant you, but until you hear them (alright, US — you got me…) speak about their sport, you never realize the magnitude of departure from the norm. Just one conversation reveals this complex and systematic language packed with phrase after acronym whose meaning only draws credibility from the tone of confidence of the cyclist who speaks them. On the outset, you would think this language actually has basis on something firm, something solid. But as you begin to become more and more inoculated, eventually adopting it for yourself, you start to realize that 2/3 of […]
- [Endurance Nutrition Vol. 1](https://iamsigma.com/endurance-nutrition-vol-1/): When one considers a strategy for supplying the body with what it needs for any type of sustained activity (by sustained, I mean activity in excess of 4hrs), it seems almost second-nature to include complex foods, rather than something more basic. The rationale for choices like this among the endurance athlete population is ubiquitous. If you need further evidence of this phenomenon, I encourage you to take a stroll through the transition area of an Ironman and pay particular attention to the rolling buffets attached to arrow bars and draped over top tubes – what you’ll find is a collection […]
- [Go Hard or Go Home](https://iamsigma.com/go-hard-or-go-home/): “Go hard or go home”. How many times have you heard that pedantic statement? Probably too many to count, I’m sure. Normally, the mouth from which that originates is situated about a foot above a body clad in Under-Armor holding a Gatorade in one hand and some brightly decorated protein bar in the other. You know the type, I’ll move on. Unfortunately, endurance sport isn’t immune from the effects of this Stone Age training methodology characterized by a trophy-like sense of accomplishment spawning from a desire to create the urge to vomit during each training session. Obviously, you, by now, […]
- [Using Power or Heart Rate Vol 1.](https://iamsigma.com/using-power-or-heart-rate-vol-1/): Quite simply, I have never been confronted by a more constant and seemingly endless debate than the use of power data vs heart rate (HR) to classify the intensity of efforts on the bike. For me, as a physiologist, I can easily see it both ways, thus building arguments towards the implementation of both variables separately as well as simultaneously. However, when it comes to creating synergies between real-time metabolic events (like anaerobic threshold), using heart rate INITIALLY (and I’ll come back to this later) is the only means of accurately determining how and when these events take place. Wattage […]
- [Good New Year’s Eve Advice](https://iamsigma.com/good-new-years-eve-advice/): Eat a balanced diet New Year’s Eve. Make sure you eat regular meals and snacks in order to satiate your appetite prior to any party where you’d be tempted to indulge in less-than-healthy alternatives. Some feel it is wiser starve themselves earlier in the day and indulge at night. unfortunately,  those people can expect some major GI upset, and, because the high probability of alcohol consumption, an increasing GI intolerance as the night progresses… Get active New Year’s Eve. Get in a minimum of 30minutes of exercise. Staying up later to watch the ball drop is sure to result in […]
- [5 Easy Steps to Selecting Your “A” Race this Season](https://iamsigma.com/5-easy-steps-to-selecting-your-a-race-this-season/): It’s quickly approaching that time of year.  Time to start gathering your thoughts and ideas towards success of your upcoming season.  All I can say is, “Giddy Up!”  I love this time of year, but I’m often approached by many athletes with questions of how to plan for a successful and stress-free calendar year.  If you are like these athletes,  you have put in some serious miles on the roads and trails this off-season, but if you have no idea if you are doing in regards to your event planning, it can make for an unsettling feeling and rob you […]
- [The “Secret” Antioxident?](https://iamsigma.com/the-secret-antioxident/): For decades, the nutritional community has been aware of the benefit of foods high in antioxidant value. However, most research has been limited to reducing the impact of certain types of oxidative stress (which can deteriorate the way cells function in your body) commonly associated in stress-filled lifestyles. We now have evidence to suggest that a certain class of antioxidant can not only reduce your chances of developing cancer and chronic disease, but it can also improve the way your body ages, can reduce any kind of inflammatory response, and reduce the effect of soreness commonly associated with ANY type […]
- [Jerry Humphreys Joins Sigma Team](https://iamsigma.com/jerry-humphreys-joins-sigma-team/): We are thrilled to announce the joining of Jerry Humphreys to the Sigma Human Performance team..Jerry, a resident of Scottsdale Arizona has a cumulative 25yrs in the operation and administration of retail and service-oriented businesses within the health, performance, and recreation sector.

- [The Truth About Max Heart Rate](https://iamsigma.com/max-heart-rate/): As of late, I have received numerous questions via email or phone regarding training zones, what zones mean, and how max HR is important to the success of zone calculation. What I plan to do with the rest of this documthe time of year (proximity to key events), fitness status, and primary method of training. As you become more aerobically fit, your max HR increases due to the increased oxygen demand placed on your cardiovascular system via mitochondrial oxygen consumption (in the muscle). This can be seen during near-max efforts such as what you might encounter in a race or […]
- [How Cardio Improves Your Health](https://iamsigma.com/how-cardio-improves-your-health/): Police officers and members of law enforcement have one of the most physically and mentally demanding professions in existence. It is for this reason that the overall health of first responders is of the utmost importance. Improved mental and physical health not only ensures a reduction of work related injuries, but also has been proven to reduce the number of excessive force claims while on the job. Luckily, there is a comprehensive way for members of law enforcement to easily improve multiple aspects of their health. A simple workout routine that includes plenty of cardiovascular exercise has surprising benefits that […]
- [Accomplish Your Health Goals](https://iamsigma.com/accomplish-your-health-goals/): There are a multitude of studies that reveal that when members of law enforcement make significant changes in their mental and physical health, their quality of life is greatly impacted both on and off duty. An increase in health while on the job also leads to the reduction of cardiovascular diseases even post-career. Changing your heath means changing your life, which can be incredibly daunting to members of law enforcement and civilians alike. Setting achievable heath goals is easy with a few time-honored tricks that are recommended by nutritional professionals and trainers alike. These tips will make changing your life […]
- [Benefits of Metabolic Screening](https://iamsigma.com/benefits-of-metabolic-screening/): One of the best first steps in creating an effective health and fitness plan is undergoing Metabolic Screening. This personalized scientific testing is an essential part of changing your BMI and improving your overall health.   What is Metabolic Screening? This data recovered from your metabolic screening reveals your individual resting metabolic rate, which is valuable information that provides insight into how efficiently your body burns fat for energy. Metabolic Screening allows professionals to break down your current health into measurable data. Knowing how many calories you burn while at rest gives insight into how many daily calories you require […]
- [3 Ways to Prevent Early Heart Attacks](https://iamsigma.com/3-ways-to-prevent-early-heart-attacks/): Law enforcement professionals and first responders are at an increased risk when it comes to heart attacks and other cardiovascular issues. According to the Harvard School of Public Health, police officers face up to a 70% higher risk of heart attack while in stressful situations than the rest of the population. The same study found that sudden cardiac death accounted for 10% of all U.S. on-duty police deaths. While these numbers are staggering, they reveal that there is a serious problem when it comes to members of law enforcement as it relates to their cardiovascular health. The dangers of deadly […]
- [Overview of Cholesterol and Metabolic Markers](https://iamsigma.com/overview-of-cholesterol-and-metabolic-markers/): Your Results and How They Impact Your Health Frequently we have our officers reach back out to us with questions about their lab numbers and how to interpret them. “I wish I could remember what they said about that thing that was bad on my lab data…” We hear it all the time. With that in mind, I wanted to put together a little cheat sheet of some commonly confused items and create something that you can reference should you find yourself in a situation with a colleague or spouse where you’re struggling to recall exactly what was said and […]
- [Why are Members of Law Enforcement at Higher Risk for Health Issues?](https://iamsigma.com/why-are-members-of-law-enforcement-at-higher-risk-for-health-issues-2/): Many people often think that the dangers of being a first responder disappear when each shift ends. Unfortunately, officers are 25 times more likely to die from a heart attack or stroke than die in the line of duty. Being a member of law enforcement is an active, exciting, and thrilling profession, but officers are plagued with a host of health risks that – if left untreated – can prove to be more fatal than even the most dangerous day on the job. High Pressure Situations Members of law enforcement recognize that stress is a part of their everyday life. […]
- [Police Officer Health Risk: Irregular Hours lead to lack of sleep](https://iamsigma.com/police-officer-health-risk-irregular-hours-lead-to-lack-of-sleep/): Irregular Hours Police officers and other members of law enforcement don’t have the luxury of only working from 9 to 5. Over the years, working long, irregular hours certainly takes its toll. According to a professional study done by National Institute for Occupational Safety and Health, police officers are four times more likely to sleep less than six hours during any given 24-hour period than the general population. Mild sleep deprivation has severe short-term effects that nearly everyone has experienced. Symptoms such as decreased mental efficiency, slower reaction times, and inability to form lasting memories may seem innocent enough, but […]
- [Heart Disease: #1 Killer of Active and Retired Cops](https://iamsigma.com/heart-disease-1-killer-of-active-and-retired-cops-1/): Introduction Twenty-two years – it is staggering. The average life expectancy of a police officer in the United States is twenty-two years less than their civilian counterparts.[1]  As a police officer, life expectancy is only 57 years, compared to 69 years in the civilian sector. This, however, is just the tip of the iceberg.[2] A newly sworn officer who has just graduated the police academy is most often in the best physical shape of his or her life. That young officer has also undergone and passed a psychological screening assessment and is has been determined to be in good mental […]

Officers concerned about their health and well-being can now turn to this evaluation program for help. _____ Written By: Courtney Levin / Police1 BrandFocus Staff Many consider law enforcement to be one of the most dangerous professions in the world, but being killed on the job isn’t what ends up taking lives too soon – it’s heart disease. “Police officers are 25 times more likely to die of a heart attack than to be killed by the violent action of a suspect,” said Noel March, chief strategy […]
- [Police1 featured article](https://iamsigma.com/police1-feb2023-feature/): Officers can now test their level of cardiac risk through this affordable program Studies show diet and exercise alone may not be enough to prevent heart disease _____ Written By: Police1 BrandFocus Staff Law enforcement officers choose their career paths for many reasons. Some want to serve their community while others have the desire to continue the legacy of a parent or grandparent. None of them decide to become a cop to endure higher rates of hypertension, diabetes, obesity and heart disease compared to civilians. Yet despite all the good LEOs do, they experience an average life expectancy that’s 22 […]

So, why do law enforcement officers have an increased prevalence of cardiovascular disease compared to the civilian population? Is it mental stress induced by shiftwork, hypervigilance and psychological trauma? Is it lifestyle factors like diet, exercise and smoking? Is it the emotional seesaw of vast periods of boredom punctuated by moments of terror? […]
