Byte Sized Summary: a method estimating protein needs by amino acid consumption estimates that the recommended protein intake is too low. Background While the method used in this study will not be accessible to most people, we did find it noteworthy that being deficient in single amino acid can waste a slew of others, and … Continue reading Are you getting enough protein? One estimate says not by 41%
Aging, oxygen muscles & mitochondria...all related. In one published analysis, genes regulating oxygen consumption are closely tied with aging. Genetics geeks (us included) will appreciate the laboriousness of relabeling genetic information so that it is useful. Table 2 shows a list of genes associated with aging from research at Skåne University and Lund University. Here is one … Continue reading 957 Genes Associated with Aging
Little Byte Summary: Male athletes on a ketogenic diet observed body composition and testosterone changes compared to a control group on a different diet. Altering dietary carbohydrate intake seems to have a profound impact on mass and blood profiles in this group. Background: We recently mentioned Prof. Jeff Volek and some ketogenic products in a … Continue reading The Effects of Ketogenic Dieting on Body Composition, Strength, Power
Context: literature on muscle contraction and muscle fiber is often focused around two proteins, actin and myosin. Here are some of the latest findings on actin from a biotechnology research group in the University of Wroclaw, in Poland: "Actin is highly conserved and it is the most widespread protein in eukaryotic cells. One of the most important … Continue reading A Tid-Byte More on Actin
Yes, that's right, it has been done. More than once. Actually, some of us at Little Byte have received a lot of slack consuming protein this way, especially for recipes adding Diet Coke(R). Full disclosure: these recipes do not bring the boys (or girls) to the yard. Turns out, we are not the only ones doing this … Continue reading The Tuna Fish Milkshake does not bring anyone to the “Yard”, but it’s still whole protein
If you have had any genetic tests, you've probably come across the "sprinter gene", or Actin. Here is a paper showing that there are multiple actins, each with small differences in amino acid structure. These include cariac-, smooth-, and muscle- isoforms. Interestingly, small differences can lead to different function: Although actin is often thought of … Continue reading Actins: the “sprinter” gene family has multiple isoforms
A common question is: "How are amino acids related to peptides and proteins"? Simple answer: amino acids are like train cars, peptides are short trains, and proteins are long trains. So, is the nutritive value of a protein (train) greater than the sum of its amino acid (train car) parts? The short answer is yes, … Continue reading Does Whey Protein make you feel more full than the simple amino acids?
Byte-sized spoiler: one study shows pea protein increased muscle mass with weight training, and there was no difference between pea and whey groups. If you haven't seen it at the store already, you can now get 10g pea protein per serving from the the nut milk brand Silk. I purchased some at SafeWay, and it … Continue reading Pea Protein may be an alternative to Whey for weight lifters to gain muscle
Have you ever wondered what those whole-body vibration systems at the gym actually do, beyond making everyone stare? Researchers in Zurich added those vibrations in to a weight training program, and compared it to the same weigh training without the vibrations. In addition to vibration, they also added occlusion, which is basically just a way of … Continue reading Ever wonder about those whole-body vibrating systems? Here is a clinical study on muscle gain.
