Musculature - the key to healthy aging

by seca-us

Changes in the musculoskeletal system occur during the aging process that affect muscles, bones, tendons and ligaments and result in a decrease in motor skills. The loss of skeletal muscle mass leads to an impairment of physical functionality and quality of life. This degenerative age-related degradation of skeletal muscle mass is also known as sarcopenia and affects between 10% and 40% of people over the age of 60, depending on the definition used.

What everyone needs to know about the muscular system

by seca-us

“Muscle” stems from the Latin word musculus which translates as “tiny mouse” and alludes to the similarity of how a contracting muscle looks like a tiny mouse moving under the skin. A person would be unable to move or even stand up straight if they didn’t have any muscles. The heart would not be able to beat and the digestive tract could not do its job.

by seca-us

Coffee is highly prized for its stimulating effect on increasing the metabolic rate, and is an integral part of many people’s daily diet. Recent studies now reveal that caffeine raises the consumption of energy in the human body.

Caution with obesity in the summer heat

by seca-us

Temperatures are hitting record highs all around the world, which not only put a strain on the body but can be life-threatening too. Every year, thousands of people lose their lives during heatwaves. Very young people, older people and those with chronic illnesses are particularly at risk. There is, however, another factor that has a major impact on heat intolerance – obesity.

Why salt makes us hungry

by seca-us

As far as nutrition goes, salt does not fare very well. Consuming excess amounts of salt is associated first and foremost with the development of arterial hypertension and cardiovascular diseases. In spite of these fears, the daily salt intake of 5 grams recommended by WHO is exceeded by many people. Two simulated space missions (2009 and 2011) provided a surprising insight into how the body deals with high doses of salt.

Water – the key component in our body

by seca-us

Water does not only fulfil life-critical functions, it is by far the most frequent link within the human body. Depending on age, gender and physical condition, body weight is made up of roughly 55% to 65% of total body water (TBW). This can then be subdivided into intracellular and extracellular water. Intracellular water (ICW) is the main component of the cell interior or cytoplasm and accounts for around 60% of TBW. The rest of the water fraction comprises extracellular water (ECW). As the basis of all bodily fluids, it is found as intravascular water in the blood and lymphatic vessels. and as interstitial water in intercellular spaces.

Obesity – if only the scalpel could help

by seca-us

While most people can lose excess weight through dietary changes and exercise, for some it can be an almost impossible task. This is especially true for people with severe obesity and a Body Mass Index (BMI) over 40kg/m². When the usual weight reduction methods have reached their limits, bariatric surgery is often the only way out.

Should I skip breakfast or not?

by seca-us

International nutritional associations continue to stress the importance of a balanced breakfast. However, for many people, the “most important meal of the day“ has not been so important for some time. An estimated third of people in industrialised nations even misses out on breakfast altogether. Particularly in the light of the continually growing obesity epidemic, there are discussions around whether regular breakfast promotes weight gain or works against it.
