Body fat can affect mental health

How muscle mass affects your health

Muscles are often described as the "engine" in the fat and calorie burning mechanism. An increase in muscle mass can reduce body fat, strengthen the immune system, improve energy levels and also reduce stress.

The many benefits of muscle mass

If you want to build muscle or maintain your muscle mass, here you will find out everything about muscles and their health effects, the dangers of age-related muscle loss, ways to measure muscle mass, including bioelectrical impedance analysis, and tips for achieving high muscle mass.

Muscles are denser than fat cellswhich may result in not losing weight for the time being, even though you increase your activity level. Because you add lean muscle mass - a long-term positive development for your health.

What can you do when you are low on muscle mass or want to maintain your muscle mass? See how muscle mass is measured, its benefits, and what you can do to gain muscle mass here.

Learn the science behind the mechanisms of muscle growth and realize its importance to your health.

What is muscle mass?

Put simply, muscle mass is the amount of muscle in your body, including skeletal muscles, smooth muscles, and heart muscles.

Along with the fat mass and the bone mass it can be part of your Total body composition be measured.

Skeletal muscle is made up of muscle fibers, or myofibers, each of which is a single muscle cell. They are connected to one another and surrounded by connective tissue, the so-called epimysium.

About 20-80 muscle fibers form a fascicle. The muscles are separated from one another by fascia, the connective tissue outside the epimysium. Tendons connect muscles to bones.

What is the difference between lean body mass and lean muscle mass?

These terms are often used interchangeably, but have different meanings. Lean body mass includes muscle mass as well as the weight of your organs, bones, skin, and body water. So everything except body fat. Muscle mass, on the other hand, only refers to the weight of your muscles.

How is muscle mass measured?

Muscle mass can be measured in a doctor's office or in a clinical setting using a variety of methods.

A report in the Journal of Clinical Medicine lists several methods including BMI (a flawed method because it could underestimate the loss of lean mass) and measurement of the muscle size of the arm, bioelectrical impedance analysis, Dual-energy X-ray absorptiometry and computed tomography.

More options, Measure your muscle mass, are calculating your body fat percentage, using a U.S. military formula, or doing an MRI. At home, the percentage of muscle mass can be measured using a smart scale that calculates body composition.

Why do muscles play a crucial role in health?

Everyone knows the importance of muscle mass for increased exercise performance, but it is also relevant to your overall health. In an article in the American Journal of Clinical Nutrition entitled "The Underestimated Role of Muscles in Health and Disease," researchers point out that Muscles play a significant role in whole body protein metabolism play, which is especially important when it comes to how your body reacts to stress - including recovery from trauma or illness.

Muscle mass may also help in the prevention of certain medical conditions and chronic diseases. In addition, through the Build muscle mass with more energy and stronger muscles to accomplish the tasks of daily living.

How insufficient muscle mass affects your health

In contrast, low muscle mass has a negative impact on your overall health. In an article in the Annals of Medicine entitled "Implications of Low Muscle Mass Across the Supply Continuum: A Narrative Review," the authors suggest that one low muscle mass negative effects can have on the entire health care chain:

"Low muscle mass is associated with consequences such as higher surgical and post-operative complications, longer hospital stays, lower physical function, poorer quality of life and shorter lifespan."

Another study published in PLoS One found that "Muscle mass changed the ratio of BMI to obesity and mortality". The lower the muscle mass, the higher the risk of mortality.

The risk of sarcopenia

Muscle wasting tends to increase with age. Sarcopenia or the age-related muscle wasting starts at age 30 - some estimates say it starts even earlier, namely 25 - and causes muscle wasting of up to 3 to 5% per decade. Untreated sarcopenia, like osteoporosis, can increase Risk of falls and fractures to lead.

In a report published in Frontiers of Endocrinology, the authors state: “The aging of the musculoskeletal system is a major public health problem and is a concern because of significant demographic changes in the population a high risk of falling, the loss of independence for older people and institutionalization associated with poor health outcomes. "

In addition to age, gender, height and weight can also be decisive how much muscle mass you have. For example, a study in the Journal of Applied Physiology found that Men have more skeletal muscle mass than women and the gender difference is greater, especially in the upper body.

How many muscles do i need?

In general, the normal range for muscle mass is as follows:

How do muscles grow?

When you exercise, you essentially cause Trauma to your muscles and your body works to repair or replace the damaged cells.

During this process, the trauma activates satellite cells that are outside of your muscle fibers. These then start to multiply.

Some of them fuse with your muscle fibers to form new muscle fibers and repair damaged ones, increasing the thickness and number of your muscle cells.

Why is muscle mass good for the immune system?

Exercise can help boost the immune system - in part because of muscle mass. In a 2019 report in the Journal of Sport and Health Science, the authors found that exercise had anti-inflammatory effects, and "Habitual exercise improves immune regulation and the occurrence of age-related dysfunctions is delayed ”.

Why? Several studies suggest that the proteins in muscle mass can be used by the immune system to respond to injuries. In “The Underestimated Role of Muscles in Health and Disease” the authors point out that “an altered muscle metabolism plays a key role in the development and thus in the prevention of many common pathological diseases and chronic diseases ”.

The role of muscles in anxiety

Many studies have shown that Exercise can reduce stress and anxiety. A study published in Frontiers of Psychology in 2014 with the title "The anxiolytic effects of resistance exercises" showed that muscle building training, especially resistance or strength training, Has anxiety-reducing effects.

Another 2018 study published in JAMA Psychiatry found that people with mild and moderate depression who did resistance training two or more times a week saw a significant reduction in their symptoms.

Exercise that increases your muscle mass can also have mental health benefits.

The role of muscles in insulin sensitivity

You might have heard of that excess body fat can lead to type 2 diabetes and exercise could reduce the risk of both. But did you also know that muscle mass can be the key to regulating your blood sugar?

According to a report in the Journal of Clinical Endocrinology & Metabolism Very low muscle mass is a risk factor for insulin resistance whereas "higher muscle mass (in relation to body size) is associated with better insulin sensitivity and a lower risk of pre- or overt diabetes".

Conclusion: Weight training can help you regulate blood sugar levels better.

Tips for building muscles

Weight training can help build muscle mass. However, if you've never done it before, it can be quite intimidating at first. So how can you start? First, be sure to ask your doctor before starting any new fitness routine.

If you are looking to lose excess weight as part of your fitness regimen, consider doing yourself Set weight goals and watch out for your calorie intake. WebMD recommends hire a fitness trainerwho can teach you how to exercise properly, especially if you are interested in lifting weights. You can choose whether toResistance bands, free weights, exercise equipment or don't want to use any equipment at all. Do not forget, warm up, use the right equipment and to rest between workouts.

In addition to exercise, diet also plays a role. In a report in Essays in Biochemistry, the authors state: "The timing of ingestion, the ingestion of nutrients, and the type of protein can affect protein accumulation" in muscle building. They also indicate that Creatine supplements in combination with resistance training can increase muscle mass.


Muscle mass has a positive effect on your immune system and also offers other health benefits: You can increase insulin sensitivity and delay age-related muscle breakdown. Whether you are trying to gain or maintain muscle, weight and strength training will help you with it. Talk to your doctor to devise an exercise program that works for you.
