Knickerbocker's theory does not explain why the first firm in an oligopoly decides to undertake FDI rather than to export or license. (Hills, 2008) also suggested that the imitative theory does not address the issue of whether FDI is more efficient than exporting or licensing for expanding abroad.
Isometrically, the lower back, the upper back, the abdominals, the trunk muscles, the costal muscles, and the shoulders and arms are all essential to the exercise and thus are trained when squatting with the proper form.
Standing Phase: Muscle Activation. Muscles activated in the standing phase of the squat are the same muscles that are used in the lowering phase. However, during the standing phase of the squat, these muscles shorten as they contract, producing a concentric contraction.s you lower into a squat, these muscles contract as they lengthen to control your speed. The knee extensors -- rectus femoris, vastus medialis, vastus intermedius and vastus lateralis -- contract as they lengthen to control your knees as they bend.
