In the initial position, the swimmer lies flat on their back; arms stretched forward, and legs extended backwards. In backstroke, the arms contribute most of the forward movement. The arm stroke consists of two main parts: the power phase (consisting of three separate parts) and the recovery. The arms alternate so that always one arm is underwater while the other arm is recovering. One complete arm turn is considered one cycle.
Some of these movement disorders that are candidates for marijuana-based therapies include dystonias, Huntington's disease, Parkinson's disease, and Tourette's syndrome. It is equally important to remember that anxiety and stress are likely to aggravate movement disorders symptoms.
Medical Marijuana for Cancer Patients. Cancer patients can benefit from using medical marijuana, whether as an alternative cancer treatment or to help mitigate unpleasant side effects of chemotherapy. Even lung cancer patients can use medical marijuana -- studies show that smoking marijuana does not cause cancer. In fact, studies show that marijuana slows the invasion of cervical cancer and lung cancer cells.
