If you plan to exercise on your own and under a trainer then t important that you learn the right technique of using the gym equipment rather then hurting yourself later. The injuries caused because of improper usage of gym equipment could prove to be hazardous to one’s muscles.

Let’s take an example of weight reduction program that is mostly undertaken by many to reduce unnecessary flab and weight. It is a good decision to follow a proper work-out to remain fit and healthy but the equipments used for weight reduction program are quite heavy and need to be used cautiously to avoid injury.

A squat rack, for instance is a weight bar that allows a person to do squat exercise. It ensures that you hold the rod properly in position so that it does not hit your shoulder or muscles. It makes sure that your concentration is on your exercise and not the rod held in your hand.

Another equipment used for weight reduction is bumper plate, it is important to ensure that these plates are covered with rubber because if you happen to drop them anytime, they can cause damage to the gym floor or other gym equipments. Since there are many sizes available in the gym equipment shops, it is easy to find a one that’s customized according to your requirement.

There is also an equipment called the gym boss that keeps a check on the time taken by you to do each gym activity and rings an alarm when you need to change the exercise. It also tells you the amount of time you need to spend on each gym exercise. The volume is sufficient to alarm you among the routine activities at gym environment.

All said and done, it is not only sufficient to join a gym to maintain a healthy lifestyle but choosing the right gym equipment can ensure that you definitely follow a healthy and happy life, because without following a proper workout regime with proper gym facility and guidance, one cannot achieve the set goal of following a physically fit life.

The causes of primary bone cancer are not yet known, but there may be a genetic link because it often seems to run in families. This form of cancer most often occurs in the leg, with it painful swelling just above or below the knee. The pain may be worse while standing or while in bed at night.

HOW IS IT DIAGNOSED?

Patients will he referred to a specialist to have X-rays taken and further tests such as a computerized tomography (CT) scan or magnetic resonance imaging (MRT) will he carried out So that the diagnosis can he confirmed. The most common primary bone cancer is called osteosarcoma.

Tumors are highly malignant and the disease will often spread to the lungs, so patients may also be sent for a chest X-ray.

TREATING BONE CANCER

In most cases the tumorous surgically removed and any bone that is taken away is replaced either by artificial bone or by a section of bone from elsewhere in the body or from a compatible donor. Radiotherapy or chemotherapy is normally given after surgery to get rid of any remaining cancer.

This specimen of a femur – thigh bone – shows a cancerous growth. Bone tumors are highly malignant and the cancer often spreads quickly to the lungs.

BONE METASTASES

Bone metastases or secondary bone cancer are terms for tumors that have spread from other parts of the body. Cancers prone to metastasize to bones include breast, lung, thyroid, prostate and kidney cancers. Bone metastases are more common than primary bone cancers.

Bone metastases tend to occur in elderly people and most often affect the ribs, pelvis, skull and spine. There is a tender swelling of the area and severe hone pain, which is usually worse at night. The affected bones are weakened and may easily fracture.

Patients who have already been diagnosed with cancer elsewhere in the body may have an X-ray or radionuclide scanning to discover if the cancer has spread to the bones. If this is the first sign of cancer, further such tests may be necessary, to locate the site of the primary cancer from which the metastases developed.

Treatment focuses on the primary site. A bone fracture may be fixed with metal plates or screws. Once cancer has spread to the bone any treatment is palliative not curative – chemotherapy, radiotherapy or hormone therapy may relieve pain only.

• Skeletal muscles - The bulk of the body’s muscles are skeletal muscles, which move the body. Skeletal muscles are voluntary muscles – they do not contract on their own. In response to a nerve impulse from-the brain, the muscle contracts, pulling on the bone and moving it. Muscles can only pull and never push so they work in pairs. When the biceps contracts it pulls the firearm towards the upper arm, bending the arm at the elbow. The triceps on the opposite side of the upper arm relaxes, allowing this to happen. When the triceps contracts, the biceps relaxes and the movement is reversed.
• Smooth muscles – Situated in the walls of the body’s hollow organs, such as the digestive tract, they perform automatic tasks such as propelling food along.
• Cardiac muscle – This forms the non­stop pump that is the heart.

• Some bones protect the vital organs. The skull acts as armor for the brain, and the pelvic hones keep abdominal organs from being damaged. The movement of the ribs aids the process of breathing and they also protect the organs of the chest, such as the heart and lungs.
• The bones of the ear help with hearing. They act as amplifiers when sound passes from the outside world through on its way to the brain.
• The bone marrow inside flat bone as the shoulder blades and breastbone a range of blood cells.

THE JOINTS

• A joint is the junction between two or more bones. Some joints are fixed, such as of the skull, while others, such cartilaginous joints between the vertebrae of the spine, have hardly any However, most joints in the both freely and are known as Synovial joints. The ends of the bones meeting at synovial joints are covered with a thin layer of cartilage to stop them grinding against each other. They are lubricated, to allow smooth by a thin layer of fluid called Synovial fluid. The ligaments are strong fibrous strips that hold bones together at the joint them from moving too far apart.
