Because solid food takes more time to digest and to break down the protein and send it to the muscles, it can be best to take a protein shake immediately following a workout, since protein shakes only take about 30 minutes to reach the muscle after ingestion.
selectivity. (analytical chemistry). The ability of a type of method or instrumentation to respond to a specified substance or constituent and not to others. (electronics). The ability of a radio receiver to separate a desired signal frequency from other signal frequencies, some of which may differ only slightly from the desired value.
Modern methods oftencomprise several strategies that introduce their own selectivity toreduce interferences. In this way, highly selective methods can beobtained. The correct use of the term selectivity and its clear distinctionfrom the term specificity are discussed. Selectivity ispromoted.
