Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
dangerous flexibility program consists of exercises that place unusual and unnecessary stretch and/or force on muscles, joints, and nerves. Many so-called stretching exercises have the potential to do more harm than good. No one should do an exercise that has the potential to result in degenerative changes in joints and nerves over time. Dangerous flexibility exercises that involve placing the head and neck (such as the plough and shoulder stand bicycling), knees (e.g., the deep knee bends and quadriceps stretch), and low back in an awkward or questionable position should be avoided. It is unfortunate that so little credible information is available to athletes, coaches, and individuals interested in flexibility training. The content in this chapter should help lay a solid foundation for thinking straight about which flexibility exercises should be avoided.
