Central vs. Peripheral manifestations of muscular weakness in persons with Parkinson's Disease

Parkinson's Disease (PD) is a central nervous system disease that affects muscular strength. Although central in nature, some peripheral maladaptation is seen from disuse. The purpose of this investigation is to discern the central vs. peripheral manifestation of weakness and develop a protocol to monitor central vs. peripheral adaptations to resistance exercise in persons with PD.

Identifying predictors of vertical jump performance

Vertical jump (VJ) is an important factor in performance, and may be decisive in some sports. Previous VJ research has established its relationship with some strength variables and BF%. However, its relationship with some anthropometric variables has not been widely investigated. The purpose of this study is to examine the relationship between VJ and some selected morphologic and strength variables.

Reliability and validity of accelerometer-derived expressions of force and power during countermovement and non-countermovement jump squats

Previous research has shown that expressions of power during loaded exercise tend to be better correlated with dynamic performance than typical tests of strength. However, the equipment necessary for this purpose is currently largely limited to laboratory settings. If a portable, low-cost device is capable of providing valid and reliable data during loaded exercises, it may have great utility in a variety of settings. The purpose of this investigation is to establish the level of reliability and validity of a portable accelerometer (Myotest®) during load-spectrum countermovement and non-countermovement jump squats.
