Introduction Despite living in this modern era of technology, living with a disease that has no treatment can be difficult, a struggle that people with Charcot-Marie-Tooth (CMT) disease have to go through. Living with this disease can significantly impact mobility and independence. However, with the right approach, exercise and physical therapy can play a crucial… Read More
Introduction In an isotonic contraction, tension remains the same, whilst the muscle’s length changes. Isotonic contractions differ from isokinetic contractions in that in isokinetic contractions the muscle speed remains constant. While superficially identical, as the muscle’s force changes via the length-tension relationship during a contraction, an isotonic contraction will keep force constant while velocity changes,… Read More
Introduction An isometric exercise device is a device used to exercise most body parts including the wrist and is often used as part of physical therapy or in order to build muscle strength in a low impact manner. Devices can range in size from large bulky machines used by physicians to small hand-held devices that… Read More
Introduction “Dynamic Tension” is the name Charles Atlas gave to the system of physical exercises that he first popularised in the 1920s. Dynamic Tension is a self-resistance exercise method which pits muscle against muscle. The practitioner tenses the muscles of a given body part and then moves the body part against the tension as if… Read More
Introduction An isometric exercise is an exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term “isometric” combines the Greek words isos (equal) and -metria (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change,… Read More
Introduction The Armstrong limit or Armstrong’s line is a measure of altitude above which atmospheric pressure is sufficiently low that water boils at the normal temperature of the human body. Exposure to pressure below this limit results in a rapid loss of consciousness, followed by a series of changes to cardiovascular and neurological functions, and… Read More
Introduction The Kármán line (or von Kármán line) is a conventional definition of the edge of space. It is not universally accepted. The international record-keeping body FAI (Fédération aéronautique internationale) defines the Kármán line at an altitude of 100 kilometres (54 nautical miles; 62 miles; 330,000 feet) above mean sea level. Refer to Armstrong Limit.… Read More
