How to Gain Muscular Strength

Muscular strength is the maximum force that a muscle or muscle group can exert in a single contraction. It is best developed by some form of progressive resistance exercise, for example, weight training with free weights (barbells and dumbbells) or single multistation machine weights. These exercises are demonstrated on exercise machines and free weights, these methods are equivalent and work the same muscle groups.The two types of muscular contractions are static and dynamic. Dynamic contractions occur when muscles shorten and move the bones to which they are attached, producing movement around a joint. Dynamic movements consist of concentric and eccentric muscle contractions . A concentric contraction occurs when a muscle shortens as it develops the tension to overcome an external resistance. An eccentric contraction occurs when the muscle lengthens and the
weight or resistance is slowly returned to the starting position. In eccentric contractions the muscles are resisting the force of gravity as they lengthen, so the weight is not allowed to free fall.

Static muscular contraction occurs when muscles exert force but do not shorten because the resistance is greater than the contractile force of the muscle. Static contractions are isometric, which literally means “equal length.” Considerable force can be generated by contracting muscles isometrically.

Hypersomnia: An Overview

Hypersomnia is a sleep disorder that is characterized by sleeping too much, experiencing excessive daytime sleepiness or a combination of the two. Hypersomnia is not the same as feeling tired due to poor quality sleep or not getting enough sleep. Often, people with hypersomnia fall asleep suddenly throughout the day, a symptom the condition shares with narcolepsy. Symptoms of Hypersomnia Symptoms of hypersomnia often develop in adolescence or early adulthood. People with hypersomnia may sleep for up to 12 hours at a time, but still wake up feeling tired. Individuals may struggle to wake up after deep sleep and seem disoriented and confused. Hypersomnia often develops gradually, making it difficult for people to realize they are sleeping too much. Signs associated with hypersomnia include: Anxiety Headaches Irritation Loss of appetite Low energy levels Memory problems "Nap attacks" during the day Restlessness Sleeping too much Slow speech Slow thought proce...

Irritable Bowel Disease Syndrome (IBS)

IBS is a very common disorder that affects the functioning of the bowel. Although the severity of the condition (also occasionally called  spastic colon ) can vary considerably from one patient to another, typical characteristics include changes in bowel habits ranging from diarrhea to constipation, cramp-like pains, bloating and a feeling of "gassiness." For some sufferers, IBS is little more than a minor inconvenience; for others it can be totally disabling. In extreme cases, the patient is unable to travel, function in the workplace or enjoy socializing. Common Misconceptions Irritable bowel syndrome is not . . . an imaginary disease.  IBS has biological causes and biological symptoms and is certainly not a condition that is "all in your mind. " caused by other diseases  such as gallstones or ulcers. an infection , although it can sometimes be triggered by a bout of gastroenteritis or similar digestive system disorders. hereditary . a precursor to c...

Gastrointestinal Defects

Birth defects, also known as "congenital abnormalities," are structural defects in some part or system of the body that can affect the body's function. These congenital defects occur during fetal development, and are present in a baby from birth. Like other complex body systems, the gastrointestinal system (or digestive system), responsible for digestion and extracting nutrients from food, is vulnerable to congenital defects during its development. Healthy Gastrointestinal Tract Function The gastrointestinal system is made up of several organs, including the: Mouth Esophagus Stomach Small intestine: Duodenum, jejunum and ileum Large intestine: Cecum, colon, rectum and anus. In healthy people, food enters the mouth, and is chewed and swallowed, passing through the esophagus to the stomach. The stomach breaks down the food, then passes it into the intestines, where it is digested further, and particles from the food can be absorbed. Waste is stored in the r...
