Secondly, applied research, which is the application of basic research to understanding how behaviour can be changed in everyday setting. When applied research is conducted using samples that are representative of the population to demonstrate effective behaviour change it is particularly relevant to policy makers.
Making the world better, one answer at a time. During skeletal muscle contraction calcium ions expose myosin binding sites on to the actin. When a nerve sends a signal to a muscle to do some action the release of acetylcholine at the neuromuscular junction triggers calcium to be released into the cytoplasm. At rest, the cell has a low concentration of calcium.
Calcium and magnesium work together to control muscle contraction. Both minerals interact with the proteins actin and myosin -- structural proteins that shorten with each muscle contraction, then lengthen to relax your muscles.ctin and myosin rely on calcium to shorten and contract your muscles, then rely on magnesium to relax after a contraction. While low calcium levels primarily affect your bones -- causing bone loss and putting you at risk for osteoporosis -- magnesium deficiency affects your muscles, causing abnormal muscle contraction.
