Running Shorts
Running shorts are a specialized form of shorts worn by runners. Often the cut of a running short is quite short, this is done in order to maximise breathability and movement, and to ensure the pant does not catch on the runners knee. Materials Running shorts are designed to facilitate comfort and free movement during exercise. Their materials are lightweight and hard-wearing. Many running shorts include an inner lining that acts as underwear, so wearing separate underwear is not necessary. Polyester is a common fabric in running shorts and makes it comfortable. Variants Many running shorts have a seam cut up the side of each leg to enable freer movement. Manufacturers define running shorts according to the length of the leg which is not cut. For example, a 3/4 seam means that 1/4 of the length is cut. * 1/2 split seam shorts are the shortest. * 3/4 split seam shorts are short, but not as short as 1/2 split seam shorts. * Square leg shorts have no split at all.

Shorts
Shorts are a garment worn over the human pelvis, pelvic area, circling the waist and splitting to cover the upper part of the legs, sometimes extending down to the knees but not covering the entire length of the leg. They are called "shorts" because they are a shortened version of trousers, which cover the entire leg, but not the foot. Shorts are typically worn in warm weather or in an environment where comfort and airflow are more important than the protection of the legs. There are a variety of shorts, ranging from knee-length short trousers that can in some situations be worn as formal clothes to beachwear and athletic shorts. Some types of shorts are typically worn by women, such as culottes, which are a divided skirt resembling a pair of loose-cut shorts. Terminological differences The British English term, ''short trousers'', is used, only for shorts that are a short version of ordinary trousers (i.e., ''pants'' or ''slacks'' in American English). For example: tailored ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.Biewener, A. A. 2003. Animal Locomotion. Oxford University Press, US. books.google.com/ref> A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to Sprint (running), sprinting. Running in humans is associated with improved health and life expectancy. It is assumed that the ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyester
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less Fireproofing, fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
