This study examined the laterality of the supporting leg in postural stability during a one-leg stance test on an unstable moving platform and its practice effect. 30 male university students were evaluated using the omnidirection stability index (OSI) during a one-leg stance test on an unstable moving platform (three trials). The leg used when kicking a ball was defined as the manipulation leg...

efficiency of numerical methods is an important problem in dynamic nonlinear analyses. it is possible to use of numerical methods such as beta-newmark in order to investigate the structural response behavior of the dynamic systems under random sea wave loads but because of necessity to analysis the offshore systems for extensive time to fatigue study it is important to use of simple stable meth...

In general, rearranging the legs of a StewartGough platform, i.e., changing the locations of its leg attachments, modifies the platform singularity locus in a rather unexpected way. Nevertheless, some leg rearrangements have been recently found to leave singularities invariant. In this work, a summary of the some of such singularity-invariant leg rearrangements are presented, and their practica...

Knowledge of whole-body energy transfer strategies during football instep kicking can help inform empirically grounded training practices. The aim this study was thus to investigate 15 semi-professional players performing kicks for speed and accuracy. Three-dimensional kinematics GRFs (both 1000 Hz) were incorporated into segment power analyses derive transfers between the support leg, torso, p...

Oxygen levels (tension, saturation, and content) in blood from varicose leg veins were found to be significantly lower than those in blood from normal leg veins at the same site on the limb under the same laboratory conditions. Treatment with hydroxyethylrutosides significantly increased the oxygen levels in blood from varicose veins, and this was associated with an improvement in leg symptoms ...

STUDY DESIGN A descriptive cadaveric study measuring arterial tension. OBJECTIVE Anterior lumbar surgery is technically challenging due to perioperative vascular complications. Many studies suggest approaches based on the anatomy of the abdominal vessel for safe vascular mobilization. However, the tension in the vascular structure is also important for adequate exposure of the target lesion. ...

The contractile properties of the triceps surae were evaluated in 11 patients after unilateral fracture of the lower leg and subsequent immobilization for 135 +/- 68 days. Calf muscle cross-sectional area (plus bone: CSA) was assessed from anthropometric measurement. It was shown that the injured leg had a faster time to peak tension and increased half-relaxation time (1/2 RT); twitch force (Pt...
