If Only He Knew His Lactose Gene Result!
Well actually, Mighty Mouse was genetically created by Professor Richard Hanson in Cleveland a few years ago! Professor Hanson studied the role of the cytosolic form of phosphoenolpyruvate carboxykinase (PEPCK-C) in skeletal muscle. PEPCK-Cmus mice were created by introducing the cDNA for the enzyme, linked to the human alpha-skeletal actin gene promoter, into their germ line
Busting one set of insulin myths clearly wasn’t enough for our fitness expert Mark Gilbert, so he’s returned to lift the lid on a second set of rumours surrounding the peptide hormone.
What if we told you that a significant number of people have a certain gene type (a version of an ‘insertion/deletion’ genotype) that would allow them to beat a drug test? Well, it’s true!...
We have long known that people would start to become curious about the potential to use genetics testing to identify genetically gifted youngsters who could be nurtured as potential Olympians...
Here at FitnessGenes™, it’s the detail of theories that interests us, and we believe this is a phenomenal example of philosophy, hypothesis, and science. But first, a little history.
This is a really interesting piece of research published this month in Cell Metabolism. Sean Curran and Shanshan Pang identify a collection of genes that allow an organism to adapt to different diets and show that, without them, even minor tweaks to diet can cause premature ageing and death.
In April 1953, this sentence appeared in the scientific paper where James Watson and Francis Crick presented the structure of the DNA helix, the molecule that carries genetic information from one generation to the other: that is the discovery of DNA!
FitnessGenes CSO Dr Samantha Decombel discusses the topic of Epigenetics, and explains why it is vital to consider their impact when constructing your genetic profile.

Vitamin D has been a hot topic of conversation this week as leading health organisations recommended that many of us need to increase our intake to maintain healthy levels. But is your genotype putting you at an increased risk of vitamin D deficiency? Read this week's blog post to learn the vitamin's function, how it can affect physical performance, and how you can be sure you're getting enough.

In most sports, there are typically one or two nations that are synonymous with success: New Zealand with Rugby; Germany or Brazil in football; the USA in basketball, baseball, and American football. Team sports are difficult to analyze from a genetics perspective. Running however, is a pure and natural sport. So given the incredibly low barrier to entry in running, global competition should really be fierce…..except it’s not.

Sleep should be the foundation of your healthy lifestyle. We explain the science and offer tips to help you get a better night's sleep
Around 100 trillion bacteria, viruses and fungi are all living happily in your gut, helping to digest food, produce vitamins and maintain immune function. We know that changes in our diet can alter the composition of these microorganisms in our gut, which in turn can have major effects on our health and fitness. But what about exercise? Can that alter our gut bacteria? Our science team takes a closer look.

A new study shows that weight cycling, which refers to extreme fluctuations in bodyweight, increases the risk of death. Our science team takes a deeper look at the research.
According to a new study, too many of us are responding ‘yes’ when posed this question. That is, several people incorrectly think they have an allergy. The study, published in the journal JAMA Open Network, found that around 1 in 5 people in the US believe they have a food allergy. In reality, far fewer (closer to 1 in 10) people actually suffer from a true allergy. Many of these people instead experience symptoms better described by the term ‘food intolerance.’ So, just what is an allergy? And how is it different from a food intolerance?
According to a new study, taking the stairs in short bouts leads to better aerobic fitness and muscle strength.
The Superbowl is this weekend and NFL fans are likely to be treated to a veritable feast of sporting prowess. But, did you know that the overwhelming majority of elite American Football players are in fact overweight or obese?
We all know that “exercise is good for the heart” – but, what exactly does this mean? In celebration of National Heart Month (and, perhaps somewhat spuriously, Valentine’s day), we explore some of the changes your heart undergoes in response to regular, vigorous exercise.
It’s one of the simplest yet most effective bodyweight exercises around: the humble push-up (or press up). A staple of high-school gym class, military training and HIIT workouts, the push-up engages several muscle groups, including the pectorals, deltoids, triceps and core muscles. According to new research, push-ups may also be particularly good for your heart.

Serotonin (also known as 5-HT) is often dubbed our “happiness hormone.” It is a neurotransmitter (i.e. a nerve communication molecule) involved in the regulation of our mood and emotions, including feelings of anxiety, surprise and happiness. Brain circuits that use serotonin also control our sleep pattern, food intake, processing of pain, and so-called ‘cognitive’ functions, such as attention, memory, decision-making and problem solving. Serotonin’s actions are not just restricted to the brain, it plays an important role in our enteric nervous system – the network of nerves that controls the function of our gut. In addition to acting as neurotransmitter, serotonin also acts as a hormone – a chemical signal that is transported in the bloodstream. Cells lining our digestive system produce serotonin, which then enters the bloodstream, where it has an effect on blood clotting, wound healing and blood flow.

“Mitochondria are the powerhouses of the cell” You may remember that neat phrase from high school biology class. Our mitochondria (single = mitochondrion) are specialized structures or “organelles” within our cells that are responsible for producing energy. More specifically, mitochondria carry out cell respiration - the process by which we convert chemical energy from food into a common energy currency that can be used to power all sorts of cellular functions. Such cellular functions include the transport of molecules, growth of new cells and the contraction of muscle fibers, all of which require an energy currency molecule called adenosine tri-phosphate or ATP. This trait looks at how well your muscles grow and generate new mitochondria. This process, called mitochondrial biogenesis, plays a major role in exercise (particularly endurance / aerobic exercise) performance.
mTOR stands for Mammalian Target of Rapamycin. It is a key molecule that regulates the growth of cells in response to various stimuli, including: the availability of nutrients, changes in energy balance, hormones, changes in blood flow and oxygen delivery, and mechanical load on muscles (e.g. as part of resistance training). mTOR controls the growth and production (or ‘synthesis’) of protein in various types of cells, including muscle cells (muscle fibers). Enlargement of muscle fibers (hypertophy) relies upon mTOR signalling. It therefore plays an important role in muscle gains following exercise. mTOR also regulates a process called autophagy - the breakdown and recycling of old, faulty and damaged cell components. This process helps to rejuvenate cells and influences how quickly our cells age. mTOR is therefore crucially involved in the ageing process.
There is an overwhelming amount of information about COVID-19 at the moment, and much of it can appear complicated, or, unfortunately, even be misleading. The aim of this explainer article is to distil lots of the existing scientific research and studies into one place.
