limited situation" but in both upper and lower limb movements, at varying
speeds, as well as during trunk perturbation (expected and unexpected),
independent of direction of movement. >>
*** I have seen many of those studies and each one has been carried out
according to a certain protocol with specific scope and limitations, as is
the case with all scientific studies. Their findings still do not imply
universality under all non-pathological conditions. Have you read any
studies which have examined the differences in TrAb involvement during
cocontractive vs ballistic conditions (for more details of these different
types of movement, see Basmajian, "Muscles Alive")? For example, please
cite any references where TrAb monitoring has been carried out under the
complex ballistic and explosive conditions which are typical in many sports.
Some of the free standing floor exercises, saltos and manoeuvres in Olympic
gymnastics or the high jump might be interesting starting points.
