THE EFFECTS OF WEARING SPANDEX GARMENT WITH COMPRESSION BAND ON KINEMATIC VARIABLES DURING A GOLF SWING

The purpose of this study was to investigate how spandex garment with compressive band affects kinematic variables during a golf swing. The X-factor and angular velocity of the club in EG were increased during the down swing phase, whereas the significant changes of other kinematic variables were not found in this study. Thus, the effects of wearing spandex garment with compression band cannot be explained as a function of the kinematic variables of interest. It is clear that wearing spandex garment with compressive band may enhance joint stability, which in turn may affect joint kinetics and muscle activation. This has led to suggestions of the need for further kinetic and EMG analyses to evaluate its function

Age-related changes in glycogen synthase kinase 3beta (GSK3beta) immunoreactivity in the central nervous system of rats

Although glycogen synthase kinase 3beta (GSK3beta) is emerging as a prominent drug target in the treatment of neurodegenerative diseases such as Alzheimer's disease (AD) and stroke, very little is known about age-related changes in GSK3beta expression and GSK3beta phosphorylation. Therefore, we examined age-related changes in immunoreactivities for GSK3beta and phosphorylated GSK3beta (pGSK3beta) in the central nervous system. In aged rats, there were significant increases in GSK3beta immunoreactivity in the cell bodies and processes of pyramidal cells in most cortical regions. GSK3beta immunoreactivity was also significantly increased in the pyramidal layer of CA1-3 regions, and the granule cell layer of dentate gyrus. Age-related increases were prominent in lateral septal nuclei, compared to the medial septal nuclei. Interestingly, both GSK3beta and pGSK3beta was increased in the prefrontal cortex, while GSK3beta and pGSK3beta was differentially localized in the cerebellar cortex. The first demonstration of age-related alterations in immunoreactivities for GSK3beta and pGSK3beta in the basal forebrain area and cholinergic projection targets may provide useful data for investigating the pathogenesis of age-related neurodegenerative diseases including AD
