F wave. In neuroscience, an F wave is the second of two voltage changes observed after electrical stimulation is applied to the skin surface above the distal region of a nerve. F waves are often used to measure nerve conduction velocity, and are particularly useful for evaluating conduction problems in the proximal region of nerves (i.e., portions of nerves near the spinal cord).
The success of the first permanent bobsleigh, luge, and skeleton track in KÃ¶nigssee, West Germany, completed in 1968 and first used for the world luge championships the following year, also played a factor. [7] [8] In 1969, it was decided to construct a permanent facility in Oberhof. [9]
The exact origin of skiing is unclear, but there is evidence that Scandinavians were using skis to travel and hunt over snow-covered terrain as far back as 4,000 years ago. Organized slalom races were first introduced in Europe during the 1920s and the first world championship was organized in 1931.ut skiing has been around a long time. In Sweden, scientists found some skis that are 4,500 years old. There are also cave drawings that shows that skiing is older than that.
