muscle gaining secrets - Hazards of prolonged inactivity

Humans are designed for activity

Mankind, Homo sapiens, were once a couple of hundred thousand years ago created a life out on the African savanna. There had to be physically both fast, strong, agile and sustainable. Man is still essentially the same creature then. We are to our basic design tailored for life with diverse physical activities. This includes hard efforts and the use of physical strength and agility.

Our body is very adaptable. The cells of most tissues are changed constantly replaced. Old and worn are replaced with new. The muscles, tendons, bones, etc. that are widely used and are subject to load reinforced and built upon during the renewal process. Leders movement becomes more voluminous on the trail throughout the range of motion used. Movements and activities that occur frequently becomes more finely tuned and coordinated by the nervous system becomes more "trimmed".

An important feature that is customizable is the body's ability to supply the muscle gaining secrets and other organs with oxygen and nutrients and carry away carbon dioxide and waste products. Here's bloodstream a transport medium. The heart's pumping function, lung capacity and blood vessel function is then very important. All these features can increase and improve the body regularly work hard, so that the heart beats fast and you become breathless. In everyday we call this ability to function - "conditioning". We all know that we can increase fitness through exercise, such as jogging, gymnastics or other bodily activities.

The adaptability is, however, also to structures in the body that are not regularly used will regress and thus weakened. This includes bones that become weak if not regularly exposed to high forces (osteoporosis). Muscles become weaker and less persistent and lose coordination and agility. Joints lose the range of motion and "sets to".

If we do not regularly work physically hard so reduces fitness. This means that the heart's ability to pump blood and blood vessels and decreases the ability of muscles to be take blood oxygen and energy decreases.

All life processes in humans requires energy. The energy we get from the food we eat. Substances in food is converted to blood sugar, blood lipids, and proteins. Fat is the most energy-rich. That which can not be immediately used as energy for various processes or as building blocks in the body will be stored as an energy store. The body's largest energy storage is the fatty tissue that are on visible parts but also invisibly inside the body such as the abdomen. If you give your body more energy than it will take will thus form more fat tissue - we become "thick" and overweight.

Muscle work requires that much energy. The body's need for energy is therefore very dependent on how long and hard we work the muscles. Heavy physical work requires a lot of energy. Sedentary requires very little energy. It is therefore likely that anyone who has a physically inactive life, for example, a sedentary lifestyle, will provide the body with more energy-rich food than what is spent. The result is that increasing the amount of adipose tissue and the body weight goes up.

Corresponding adjustments in the brain. Mental stimulation accelerates its development and to maintain the brain's complex functions, such as memory.

Both muscle strength and endurance have thus regularly used to maintain as well as mobility and flexibility in the joints, connective tissue and muscle and body balance. The same applies to fitness. Stamina, strength, etc. is a "perishable" that only lasts a short period. They need constantly renewed and built. Even after a week of complete inactivity, such as bed rest, begins fitness and muscle strength to decline. After a prolonged inactivity has also bones, tendons and connective tissue decreased in strength.

Our life has evolved towards less physical activity

during the past 100 years, much of the physically heavy and energy intensive elements of life disappeared. This applies to private life where cars, washing machines, vacuum cleaners and lawn mowers taken over the man formerly did with his physical strength. Within the workplace, the number of workers in physically heavy occupations greatly reduced, for example agriculture, forestry, manufacturing, etc.. In heavy occupations, we have strived to reduce the heavy physical work to be performed. Machinery and tools do the heavy work. There is still, however, many professions, at least at times, is physically heavy, such as health care, construction, cleaning.

The number employed in physically inactive and often sedentary exerciseshas sharply increased. These include computer work.

The combination of both the private and professional life for many nowadays requires very little physical activity causes the body at risk of too little training for endurance, strength, coordination, agility, etc. The risk is that you incur too large energy reserves (fat) and becoming overweight. The proportion of children and adults with overweight or obesity has greatly increased in many parts of the world. Such a development may cause a variety of health risks
