Other people's ignorance/incompetence is not something I can control.

 

I've also overheard people rationalize a great many things including: anti-vaccine agendas and the dangers of GMO foods. You and I can't fix stupid. If they were at all inclined to do some basic googling/research, I'm sure they could find proper information and facts to help them make rational decisions.

And today comes the official advice from the U.S. government: The Obama administration has released its much-anticipated update to the Dietary Guidelines.

The guidelines, which are revised every five years, are based on evolving nutrition science and serve as the government's official advice on what to eat.

One concrete change: Americans are being told to limit sugar to no more than 10 percent of daily calories.
....

 

 

Considering the target group (the lifestyle of the average American) it's good advice imho especially the strong advice to reduce sugar intake.

I wouldn't necessarily think it's the best advice for athletes/very physically active people but again it's a matter of who this is intended for.

....

There is increasing research evidence about the causal role of alcohol in cancer, accompanied by unclear and conflicting messages in the media. This paper aimed to clarify the strength of the evidence for alcohol as a cause of cancer, and the meaning of cause in this context.
....

A brief description of the nature of causal inference in epidemiology was used to frame discussion of the strength of the evidence that alcohol causes cancer, and contrast this with the case for a protective association of alcohol with cardiovascular disease.
....

Conclusions

There is strong evidence that alcohol causes cancer at seven sites in the body and probably others. Current estimates suggest that alcohol-attributable cancers at these sites make up 5.8% of all cancer deaths world-wide. Confirmation of specific biological mechanisms by which alcohol increases the incidence of each type of cancer is not required to infer that alcohol is a cause.

....

So far, research hasn't fully answered the question of how alcohol acts to cause different types of cancer. But there are several theories with good evidence. It is likely that alcohol causes different types of cancer in different ways [22].

The theory with the strongest evidence is related to how our bodies process alcohol. It is converted into another chemical called acetaldehyde. Acetaldehyde can cause cancer by damaging our DNA and preventing it from being repaired [23]. The International Agency for Research into Cancer (IARC) classes acetaldehyde associated with drinking alcohol as a Group 1 substance, which means it can cause cancer in humans [6]. Drinking alcohol greatly increases the level of acetaldehyde found in saliva [24]. And a small initial study in 2012 found higher levels of DNA damage in the mouth cells of people after drinking alcohol [25].

A couple of recent health topics I found interesting. As usual, reading the comments is very valuable to try and help identify misleading titles, etc.

""Perfecting Protein Intake in Athletes: How Much, What, and When? (and Beyond)""
article - https://www.strongerbyscience.com/athlete-protein-intake/

Good read. There is a nice summary towards the end of the most important points but I did read most of the entire article. Years ago, at which point I had already read many other fitness articles, I decided that the ballpark number I was going to use personally for "good" protein intake was going to be 0.8 g/lb/d (grams-of-protein / per-pound-of-total-bodyweight / per-day) counting strictly from dairy or meat sources (since they are the most "bioavailable" by a good margin). It feels really nice to see very authoritative articles like this, backed up with plenty of study links, that kind of justifies that number. Definitely still some new info though that I learned (possible "tricks" with leucine supplementation, minimal recommendation regardless of bodyweight, etc.). I could possibly even lower my "good" number that I have been using down to 0.7. This will probably be something I will link to people who constantly spew that bro-science citing huge protein intake requirement numbers. Those huge numbers have always bothered me.

More details can be found at both links.

There has been rumbling about topics like this for a few years now in some groups. Lots of theories too, some supported by some science, some supported by nothing at all (conspiracies) but the numbers are kind of hard to ignore especially with a study like this. How much of it is lifestyle (diet, obesity, exercise, etc.)? How much of it is environment (radiation, chemicals, etc.)? Does this mean that other hormones in the body have also changed? In what way?

I want to know the answers to some of those questions because I feel they could be important.

article - https://www.telesurtv.net/english/news/Scientists-Attempt-First-Gene-Editing-in-Live-Patient-Body-20171115-0001.html

Quote

 

Scientists in California have announced the first attempt to “edit” genes in a patient’s body to cure disease.

Experts believe that permanently altering a person’s genetic code can eliminate rare and otherwise untreatable diseases.

AP reports that Brian Madeux, a 44-year-old California resident who has a rare disease known as Hunter syndrome, intravenously “received billions of copies of a corrective gene and a genetic tool to cut his DNA in a precise spot.”
....

However, this marks the first attempt to permanently edit the genes in a patient’s body. If successful, this operation would invigorate the medical frontier of gene therapy.

The tools used in this procedure are called “zinc finger nucleases,” which operates as a tiny scissor that can precisely cut a specific section of a patient’s DNA.
....

 

If it works, it could be big.

Absolute madman. This guy took multiple pages of notes over a period of time while following content from a few of the most respect coaches who have worked with a variety of athletes out there and summerized them in a document. Anybody closely following fitness probably won't find anything earth shattering in this but it definitely has some interesting smaller details.

"Sildenafil (Viagra) Increases Muscle Protein Synthesis and Reduces Muscle Fatigue"
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4076819/

Quote

"Accordingly, we administered the phosphodiesterase 5 inhibitor sildenafil (Viagra) to generally healthy males, who receive the vast majority of phosphodiesterase 5 inhibitor prescriptions, to test the hypothesis that sildenafil would increase skeletal muscle function and protein synthesis (study design, Figure 1)."

 

Quote

"Notably, the approximate doubling of skeletal muscle protein synthesis observed in response to sildenafil is of similar magnitude to that observed in response to 100–200 mg/week testosterone injection..."

I assume you would take this in recovery?  Also I imagine taking it as a pre-workout would create a very awkward situation at the gym. 

Also I'm sure there's a joke in there about getting jacked, but I'm too lazy to find it.

Also I'm sure there's a joke in there about getting jacked, but I'm too lazy to find it. 

For starters, the study has some limitations (listed below).

  1. The majority of the subjects were fat. Average bodyfat precent was like 30%.
  2. There were only 11 subjects.
  3. The study only lasted 15 days.

That being said, no one expected numbers like this.

The way it was dosed in the test was "...sildenafil or placebo ingestion occurred approximately 1 hour before dynamometry testing..." and "... they received either daily low‐dose (25 mg) sildenafil (N = 5) or placebo (N = 6) in a randomized, double‐blinded fashion..." so yeah pretty much as a pre-workout.

I guess it could lead to awkward situations but, as far as I know, "PDE 5 inhibitors" (how they are grouped together) will not just randomly cause erections without anything to kick off the process.

A lot of people are still digesting this.

So starting in 2020 all Army soldiers are going to be taking a new physical fitness test.

article - https://www.military.com/daily-news/2018/07/09/army-will-require-all-soldiers-take-new-combat-fitness-test-2020.html

Quote

There are six events in the ACFT:

  • Strength Deadlift. This is a three-repetition maximum deadlift to test muscular strength; it mimics movement to safety and effectively lifting and carrying heavy loads.
  • Standing Power Throw. This event involves throwing a 10-pound medicine ball as far as possible over the head and to the rear. It measures upper and lower muscular power, balance and whole body flexibility.
  • Hand-Raised Push-ups. This event forces the soldier to go all the way to the floor and raise his hands before coming back up again, measuring upper-body muscular endurance.
  • A 250-Meter Sprint, Drag and Carry. This is five different events within one event -- a 50-meter sprint; a backward 50-meter drag of a 90-pound sled; a 50-meter movement; a 50-meter carry of two 40-pound kettle bells; and a final 50-meter sprint. It measures muscular strength, power, speed and reaction time.
  • Leg Tuck. A soldier hangs perpendicular to the pull-up bar and brings his knees up to his elbows and back down again for one repetition. It measures muscular strength, endurance and grip.
  • Two-Mile Run. The ACFT retains the two-mile run portion of the APFT, which is designed to measure aerobic and muscular endurance.

All events must be completed in 50 minutes or less, so there is mandated rest and a maximum time for each event, Frost said. Each soldier gets two minutes' rest between each of the first five events and five minutes of rest before the two-mile run.

Interesting.

"A Case for 1x20 Training"
article - https://www.elitefts.com/education/training/workouts-programs/a-case-for-1x20-training/
book - https://www.amazon.com/Build-Better-Athlete-American-Sports/dp/1930546785
author - https://en.wikipedia.org/wiki/Michael_Yessis

Interesting piece of research.

The idea is for an athlete to spend about 30-45 minutes doing 15-20 exercises for just 1 set each of 15-20 repititions. The idea is to hit every major joint action/motion of the body. Once progress/weight increases has stopped, you change the exercises or do a deload.

The workout example given is:

20 main lower body reps (some kind of squat)
20 main upper body push reps
80 reps of direct posterior chain work (4 different exercises)
60 reps of upper back work (3 different exercises)
20 reps of single leg movements

This would not replace specific skill training but apparently it is being proposed as adequate for even high level athletes to address imbalances, rehab injury sites, develop general mobility and stability issue. It would establish a "base" level of strength to build other skills on top of.

article - https://www.wbur.org/commonhealth/2019/05/15/cvs-test-supplements-vitamins

Quote

 

....

Rhode Island-based retail pharmacy giant CVS is launching a program to require testing of all the vitamins and supplements it sells, aiming to make sure — and assure customers — that they contain what they say they do.

"To our knowledge, this is the first time that any national retailer is requiring all vitamins and supplements to undergo third-party testing, in order to be sold on our shelves," says CVS Senior Vice President George Coleman.

More than 1,400 vitamins and supplements from 152 brands have now undergone testing, CVS says.

The testing is performed by independent inspectors — not by CVS or the supplement makers themselves. It checks for contaminants and verifies that the contents listed on the labels are correct.

CVS says 7% of the products flunked, and were either pulled from the shelves or had to change their labels.
....

 

CVS has made some interesting choices lately. The two main ones that come to mind is the minuteclinics (think really small urgent care without a doctor) and stopping cigarette sales.
