Exercise protects against heart disease in many ways. One important mechanism is by elevating HDL, a.k.a. the “good” cholesterol. It is well established that high levels of HDL are protective against cardiovascular disease and the National Cholesterol Education Program (NCEP) has emphasized increasing HDL levels to help reduce CHD risk. [2-4] However, not only HDL levels are important. Emerging research in showing that HDL quality and function is as important, if not more important for health promotion and prevention of cardiovascular and metabolic diseases…[5-7]
In this vid, I discuss the popular “Testosterone booster” supplement D-Aspartic Acid (DAA) and update my opinions of this general category of supplements.
Study mentioned in the vid:
D-Aspartic acid supplementation combined with 28 days of heavy resistance training has no effect on body composition, muscle strength, and serum hormones associated with the hypothalamo-pituitary-gonadal axis in resistance-trained men
Department of Health, Exercise and Biochemical Nutrition Lab, Human Performance, and Recreation, Baylor University, Waco, TX, USA
It was hypothesized that d-aspartic acid (D-ASP) supplementation would not increase endogenous testosterone levels or improve muscular performance associated with resistance training. Therefore, body composition, muscle strength, and serum hormone levels associated with the hypothalamo-pituitary-gonadal axis were studied after 28 days of resistance training and D-ASP supplementation. Resistance-trained men resistance trained 4 times/wk for 28 days while orally ingesting either 3 g of placebo or 3 g of D-ASP.
Data were analyzed with 2 × 2 analysis of variance (P < .05). Before and after resistance training and supplementation, body composition and muscle strength, serum gonadal hormones, and serum D-ASP and d-aspartate oxidase (DDO) were determined. Body composition and muscle strength were significantly increased in both groups in response to resistance training (P < .05) but not different from one another (P > .05). Total and free testosterone, luteinizing hormone, gonadotropin-releasing hormone, and estradiol were unchanged with resistance training and D-ASP supplementation (P > .05).
For serum D-ASP and DDO, D-ASP resulted in a slight increase compared with baseline levels (P > .05). For the D-ASP group, the levels of serum DDO were significantly increased compared with placebo (P < .05). [B]The gonadal hormones were unaffected by 28 days of D-ASP supplementation and not associated with the observed increases in muscle strength and mass.
Therefore, at the dose provided, D-ASP supplementation is ineffective in up-regulating the activity of the hypothalamo-pituitary-gonadal axis and has no anabolic or ergogenic effects in skeletal muscle.
The Barbell Bench Press is obviously the most common exercise for working the chest…yet it has a major flaw. A good portion of the movement doesn’t necessarily focus on the pecs. The top half of the movement involves a lot of triceps activation.
So how do we increase the specific tension being placed on the pecs during the barbell bench press? Easy. We focus more time on the bottom 1/4 of the exercise, where the pecs are under greater stretch.
In part 1 I introduced the new healthcare model called anti-aging medicine, and issues with the current disease oriented medical system that anti-aging medicine aims to solve. Here you will learn more about anti-aging medicine as a new medical specialty, how it differs from traditional medical practice, and what anti-aging qualified doctors can do for you.
Over the past decade, interest in anti-aging treatments and interventions aimed at promoting health, vitality and youthfulness over the life course into old age, has risen exponentially. The popularity and rise of anti-aging interventions has been fueled by the aging baby-boomer generation and the great dissatisfaction surrounding the current medical system in the US and many other Western nations.
Are you frustrated with today’s big-pharma dictated assembly line medicine with doctors who only spend 7 minutes per visit with their patients? Are you against the routine “have a symptom – take a pill” medical system mantra that is so pervasive in modern medicine? Then anti-aging medicine, a medical specialty developed and led by The American Academy of Anti-Aging Medicine (A4M) is for you.
For some reason I always seem to end up writing articles about contaminants found in various supplements we ingest, in particular creatine, but there have been others. First I wrote “What’s in your creatine?” which exposed the fact not all creatine supplement are created equal. That article single handedly changed the creatine market at the time. I followed that up with “What’s in your supplements” which was really just a continuation of the first article, with additional testing and comments. I’m calling this one, “What’s in your water?!” for lack of a better title.
I have always been conscious of the potential impurities in drinking water. My town sends out a yearly report on water quality, and has always been well below EPA limits on the chemicals they test for. Regardless, I have always used a water filter to filter my drinking water. (1)
Most standard weight training exercises operate in an up and down, forward and back plane of movement. But that leaves out the very important lateral component…and if you play any sports that require movement left or right you NEED to target those movement patterns as well.
That’s what this exercise does.
Synthetic sweeteners, toxic or safe? In this vid, I get to the bottom of this debate!
A hotly debated recent study, the SELECT trial, has casted doubt on the well documented health benefits of omega-3 fatty acids. This study found that a higher content of long-chain omega-3 fatty acids (EPA+DPA+DHA) in blood plasma was associated with a with a greater risk of low-grade (44%) and high-grade (71%) prostate cancers over a 5-year follow-up 1. Associations were similar for individual long-chain omega-3 fatty acids. Higher linoleic acid (omega-6) was associated with a 25% reduced risk of low-grade and 23% reduced risk of total prostate cancer 1 .
This has understandably generated confusion among the general public and intense discussions among health professionals and researchers. However, a deeper look at the data and study methodology reveals a different picture…
Will Brink and Dr Lopez have previously commented on the notorious omega-3 / prostate cancer study:
Here is my take on it…
