Due to a recent study and media reports – and contact by the media to comment – on this survey of teens I have addressed the possible use of HGH, and claims of increased use, by teens below:
The Rumble Roller Takes Soft Tissue Work To The The Next level
Like many people, I have my fair share of aches & pains, tight muscles, and hard earned small injuries and such. Like many, I have been using a foam roller for soft tissue work or SMFR (Self-Myofascial Release) work to improve sore muscles, tight muscles, and general recoup. I generally do my foam rolling in the morning for 15-20 minutes while the oatmeal cooks and coffee brews. It gets me ready for a day at the computer also. I also use it at the gym before workouts, a few times per week, and I find doing so reduces DOMS. Foam rolling is often referred to as “the poor mans massage therapist.” In terms of time and $$$ spent, it’s a no brainer in terms of benefits you receive. If you’re not using a foam roller regularly, you should be, like starting yesterday!
As time goes on, one notices the standard foam roller not as effective, and or, they start to break down, and a replacement needed. Some seem to last longer than others. Enter the Rumble Roller, which takes foam rolling to another level and seems to last far longer than the standard rollers. I was going to make one of my usual videos talking about the benefits of foam rollers, and why the Rumble Roller superior, but coach Charles Staley – who has some great articles here on the BrinkZone – did such a good job of it, I decided to use his vid on the topic. If interested in more information, I purchased both the standard length and shorter smaller (12″x 5″) travel length HERE
Personally, I prefer the standard (blue) firmness Rumble Roller. Highly recommended if you already use foam rollers, not recommended for those new to foam rolling for soft tissue/SMFR work as the Rumble Roller is very aggressive. Watch coach Staley’s excellent vid on the benefits of foam rolling, and why he likes the Rumble Roller over standard rollers in particular.
EDITORS NOTE: I (Will) recently did a video on ARA which discusses a study that found ARA had positive effects on strength and muscle mass, but was not able to give details on the study at that time as it had yet to be published as an abstract or full paper. Finally, Monica now covers the meat of what most people really want to know about ARA: Can it increase strength and muscle mass as a supplement? The answer appears to be a solid yes. This excellent article below covers the recent study mentioned in my vid and write up on the study and gives the details, as well as a prior study. This is the must read article of the ARA series of articles on BrinkZone!

In part 1 I outlined the background on ARA and why it traditionally has been, and still is in certain circles is, deemed the “bad guy” fatty acid. Part 2 covered its safety aspects and presented research findings indicating, to the contrary of the “ARA is bad dogma”, potential health benefits of ARA supplementation. In this part I will present new research showing potential beneficial effects of ARA supplementation, in conjunction with resistance training, on physical performance, muscle growth and strength gains…
The impetus for human studies on the effect of ARA supplementation on muscle growth and strength gains came from early studies on isolated animal muscle and muscle cell culture.[1-6] It was found that an increase in ARA flux through the COX enzyme (either induced by stretch or ARA supplementation) promotes production of the prostaglandins PGF2-alpha and PGE2 in muscle tissue, and that PGF2-alpha potently stimulates muscle protein synthesis [2, 5, 6] while PGE2 stimulates muscle degradation.[1, 2]
Frequent consumption of red and processed meat has been shown in population studies to be positively correlated with cardiovascular disease [1-3], cancer and type 2 diabetes. Recent meta-analyses also indicate that it increases total mortality . Hence, a high meat intake (regardless of its fat quantity and quality) is generally perceived to be unhealthy and something that should be avoided. However, although there are many studies documenting these associations, results are not always consistent and there are several methodological issues which weakens the strength of their findings (more on that in a bit). In the same way as the putative health risks of red meat consumption is investigated, its documented health benefits (which I will cover below) are equally as important and must be given a fair chance in the establishment of public health messages in relation to red meat consumption. In this article I will therefore cover both the risks and benefits associated with red meat consumption, and after having taken all the scientific data into consideration, argue that meat has been unfairly blamed…

I recently did a video on ARA which discusses this study that found ARA had positive effects on strength and muscle mass, but was not able to give details because it had yet to be published as an abstract or full paper. The study results are now public and I cover them below. Two previous articles on ARA ( Part I), by Monica M cover why ARA is a generally misunderstood fatty acid and not a a negative to health, (part II ) covered the safety of ARA as a supplement. Finally, Part III, cuts through the hype and bro-science to give details on ARA and it’s use as a supplement for increasing strength and muscle mass! My understanding is a full paper is in process that will also examine the specific mechanisms of ARA and its impact on strength, muscle mass, and performance.
This study looked at the effects of 1.5g per day of ARA for 8 weeks on muscle hypertrophy, body composition, strength, and power, compared to a placebo matched control. For those who don’t enjoy reading abstracts and studies, here’s the cliffs notes followed by the full details:
• The group receiving 1.5g of ARA had in increase in lean body mass (LBM) of approx 3%, corresponding to 3.5 lb (1.6 kg) compared to no changes in the placebo group
• Muscle thickness increased in the group receiving ARA (+9.5%) vs. the placebo group (+4.7%).
• There was an improvement in anaerobic power (via Wingate test which measures 30 second maximal output), which increased in the group getting ARA (+10.7%) vs. the placebo group (+3.8%).
• The group receiving ARA increased their bench press and leg press strength to a greater degree than the placebo group.
Can women suffer for “Low T” as men do? This vid covers the issue all women need to know about this “male” hormone! For additional details, see Monica’s article on the importance of testosterone in women HERE.
Study mentioned in this vid:
In this vid I give quick look at some technologies that greatly enhance solubility of compounds known for their poor solubility. Such a technology applied to various supplements could greatly improve their bioavailability. The link in the vid also takes you to another vid and article with additional info on the topic BTW.
In this vid I cover the (seemingly) never ending debate regarding the old advice that “protein intakes above your requirements will just be converted to bodyfat” that is the mantra of traditional nutrition advice. Is it true?

EDITORS NOTE: I (Will) recently did a video on ARA which discusses a recent study that found ARA had positive effects on strength and muscle mass readers will want to check out. The results of this study will be covered HERE and in a future article by Monica. This excellent article below by Monica discusses the safety of ARA supplements and possible health benefits that set the record straight on this fatty acid…
In part 1 I outlined the background to the “ARA is bad” theory, and presented studies that have refuted this notion. Part 1 also explains the importance of distinguishing the different omega-6 fatty acids, LA and ARA, and describes the bell-shaped relationship between ARA and EPA + DHA in cell membranes.
In this part you will learn about safety aspects and potential health benefits (!) of ARA supplementation…
Safety and Health Effects of ARA supplementation
With the bad reputation that ARA has, let’s start by looking at safety data. On a typical modern diet (that includes meat, eggs and fish) the average intake of ARA is approximately 100–200 mg ARA per day.[1-5] Several studies have investigated safety aspects of ARA supplementation in different populations.
When healthy volunteers were given over 7 times the usual intake of ARA (i.e. 1500 to 1700 g ARA per day, compared to usual intake of 200 mg ARA per day) in a 7 week controlled feeding study, no effects on platelet aggregation, bleeding times, the balance of vasoactive metabolites, serum lipid levels, or immune response were observed.[6-10] Likewise, in a recent study on healthy men aged 26-60 years, supplementation with 840 mg ARA per day for 4 weeks had no effect on any metabolic parameter or platelet function.
A study in healthy Japanese men and women aged 55-70 investigated whether ARA supplementation affects clinical parameters involved in cardiovascular, inflammatory, and allergic diseases. Subjects were supplemented with ARA-enriched oil (240 or 720 mg ARA per day) or placebo for 4 weeks, followed by a 4-week washout period. The fatty acid contents of plasma phospholipids, clinical parameters, and AA metabolites were determined at baseline, 2, 4, and 8 weeks. It was found that ARA content in plasma phospholipids in the ARA supplemented groups increased dose-dependently and was almost the same at 2 weeks and at 4 weeks. The elevated ARA content decreased to nearly baseline during a 4-week washout period. Contrary to expectations, during the supplementation and washout periods, no changes were observed in plasma phospholipid EPA and DHA content. There were no changes in clinical blood parameters related to cardiovascular, inflammatory and allergic diseases.
The Journal Of Special Operations Medicine (JSOM) covers a wide range of topics focused on special operations forces (SOF). Topics range from medical procedures and other medical based focus (diseases, etc) SOF can face and need medical treatment for. JSOM also covers topics such as training and injury prevention, and even topics such as nutritional supplements that may benefit SOF. For example, JSOM recently published a review of the importance of vitamin D for soldiers.
So, having a personal and professional interest in the topic, it should not be a big surprise I read this journal. Recently Dr. Kyle Hoedebecke and yours truly had an LTE published in JSOM. This short paper was in response to a review paper titled “Operational stressors on physical performance in special operators and countermeasures to improve performance: a review of the literature.” by O’Hara R, Henry A, Serres J, Russell D, Locke R.
In this review the authors concluded that “The rigors of both physical training and prolonged deployments without adequate rest and food intake can compromise physical performance.” After doing a literature search, they concluded that “Specific countermeasures for these known decrements are lacking in the scientific literature.”
Dr. Hoedebecke and I responded that there were published studies that demonstrate a number of nutritional supplements may counteract some of the decrements of training and combat specific to special operations forces (SOF) and other military personnel, and we covered a small sample of nutritional supplements that can directly assist SOF and other military personnel. This is the citation and abstract from what we submitted and was published in JSOM as response:
Hoedebecke K, Brink W. Operational stressors on physical performance in special operators and countermeasures to improve performance: a review of the literature. J Spec Oper Med. 2014 Summer;14(2):84-5.
In the article “Operational Stressors on Physical Performance in Special Operators and Countermeasures to Improve Performance: A Review of the Literature,” O’Hara and colleagues* performed a literature search for “specific countermeasures to reduce or prevent significant decrements in physical performance and reduce musculoskeletal injuries” with the conclusion that “specific countermeasures for these known decrements are lacking in the scientific literature.” This deduction, however, proves inaccurate as evidence within the military community does exist and, unfortunately, has been undervalued. Provided here are only a few examples of present Special Operations Force (SOF)-relevant supplement research.
