At which age do we start to lose muscle mass?

A thread 🧵👇

#ageing #muscle #sarcopenia
Aging is associated with the loss of muscle mass. This phenomenon is also known as sarcopenia. Around what age does this start to occur?

2/
This study investigated the influence of age on muscle mass in a large sample of adults. Skeletal muscle mass was measured with a whole-body MRI for 468 adults of 18-88 years old. People that were bedridden, had physical disabilities, or had chronic illnesses were excluded.

3/
Skeletal muscle mass is stable until the mid-40s, after which a negative correlation between muscle mass and age was observed. In addition, muscle loss appeared to accelerate with increasing age.

4/
Muscle mass loss was greater in the lower body when compared to the upper body. This may be explained by a reduction in physical activity of primarily the lower body.

5/
A limitation of the study is that it’s cross-sectional. However, cohort or intervention research is not really feasible for this research question.

6/
In conclusion, the age-related loss of muscle mass appears to begin around the age of 45 years.

How to improve your endurance capacity for increased health and performance?

Here’s a thread of some of our endurance exercise infographics 🧵👇

#endurance #performance #VO2max
Aerobic capacity is defined as the maximal rate of oxygen consumption (VO2max). A large improvement in aerobic capacity can already be achieved during an intense 10-week training program.

2/
Non-responders to exercise probably don’t exist. However, there are people that need a lot more exercise volume to obtain the same fitness benefits compared to others.

Does the order of drinking wine and beer matter for hangover severity?

A thread 🧵👇

#beer #wine #hangover
It is well established that drinking too much alcohol will result in a hangover. It is commonly suggested that the hangover will be less if you stick to one type of alcoholic drink, rather than drinking different types of drinks.

2/
In addition, there are several sayings such as: “Beer before wine and you’ll feel fine; wine before beer and you’ll feel queer”. This suggests that the order of drinks may impact the hangover.

Can the Mediterranean diet reduce heart problems?

A thread 🧵👇

#mediterranean #nuts #oliveoil Image
Mediterranean countries have lower cardiovascular mortality rates compared to northern Europe and the United States. It is often suggested that this is at least partly due to the Mediterranean diet.

2/ Image
The Mediterranean diet includes high intake of olive oil, fruit, nuts, vegetables, and cereals; a moderate intake of fish and poultry. In addition, it has a low intake of dairy products, red meat, processed meats, and sweets; and moderate wine consumption.

Data extrapolation or wishful thinking?

A thread 🧵👇

#diet #training #performance
Studies are typically relatively short (weeks to months). However, we often want to know what happens with longer-term adherence to interventions such as a training protocol or a diet.

2/
Therefore, data from studies needs to be extrapolated; make assumptions what would happen if the interventions would be continued.

Many supplements claim to improve body composition or exercise performance. Some supplements seem promising, while others don’t seem to do anything, and some can even be counterproductive.

Here’s a thread of some of our supplements infographics 🧵👇

#supplements #performance Image
Creatine is an organic compound which is naturally present in our bodies. Creatine supplementation increases muscle creatine levels, strength and muscle mass gains during resistance training.

2/ Image
Nitrate-rich beetroot juice has been shown to increase endurance performance because. Beetroot juice supplementation can also improve repeated sprint performance compared to nitrate-depleted beetroot juice.

Does the ketogenic diet impair endurance training adaptations?

A thread 🧵👇

#keto #ketones #lowcarb Image
The ketogenic diet is a very low carb, high fat diet, that claims to improve exercise performance by increasing the use of fat (fat oxidation) during exercise.

2/ Image
This study investigated the effect of 3 different diets during an intensive training period on training adaptations in elite race walkers.
