As the load the muscle is required to lift decreases, contraction velocity increases. This occurs until the muscle finally reaches its maximum contraction velocity, V max. By performing a series of constant velocity shortening contractions, a force-velocity relationship can be determined.ontractions that permit the muscle to shorten are referred to as concentric contractions. An example of a concentric contraction in the raising of a weight during a bicep curl. In concentric contractions, the force generated by the muscle is always less than the muscle's maximum (P o).

Located in the inter-Andean valley, Quito is a city of sun and sky surrounded by mountains, with three snow-capped volcanoes in view on a clear day. Its climate has been described by many as eternal spring, due to its high altitude and its location close to the equator.n this sense Quito can certainly be considered representative of many Latin American urban areas-without the magnitude of problems related to massive population centers as in Mexico and Brazil or even in Ecuador's port city of Guayaquil. As the capital city, Quito has good communication links to the rest of Ecuador.
