This study examined the effects of baseline flexibility and vertical jump ability on straight leg raise range of motion (ROM) and counter-movement jump performance (CMJ) following different volumes of stretching and potentiating exercises. ROM and CMJ were measured after two different warm-up protocols involving static stretching and potentiating exercises. Three groups of elite athletes (10 ma...

methods in this study, 16 skilled female gymnasts (mean age of 9.62 ± 1.45 years) were randomly categorized to two general warm-up with no stretching (ns, n=8) and general warm-up plus static stretching (ss, n=8) groups. the warm-up protocol included a 10-minute jogging, and the static stretch (ss) protocol included stretching programs on the different parts of body during four weeks, three tim...

Several studies have been made using submerged plates for wave-damping purpose. A pulsating flow occurs opposite to the direction of wave propagation below these wave breakers. This water flow can be used for energy production purposes. In this study, the energy efficiency of the plate wave energy converter is determined experimentally. The length of the plate L 1⁄4 1m, the water depth d 1⁄4 60...

----------------------------------------------------Abstract-----------------------------------------------------------This paper considers the problem of a laminar electrically conducting fluid as a boundary layer flow past a stretching plate and heat transfer. The nonlinear partial differential equations were transformed and the resulting ordinary differential equations were solved by using M...

Pre-stretching was carried out to modify the microstructure of Mg-Nd-Zn-Zr alloy to enhance its age strengthening. The results indicated that more heterogeneous nucleation sites can be provided by the high density of dislocations caused by the plastic pre-stretching deformation, as well as speeding up the growth rate of precipitates. Comparison of microstructure in non-pre-stretched specimens a...

Synovial joints are loaded by weight bearing, stretching, and fluid-driven shear. To simulate in vitro fluid-driven shear, we developed an "oscillating Couette flow mechanical shear loader". Oscillating Couette flow mimics relative motion of articular surfaces; hence, characterizing flow-induced shear by the loader enhances understanding of mechanotransduction in the joint tissue. Here, the ana...

The total quasigeostrophic (QG) vertical motion field is partitioned into transverse and shearwise couplets oriented parallel to, and along, the geostrophic vertical shear, respectively. The physical role played by each of these components of vertical motion in the midlatitude cyclone life cycle is then illustrated by examination of the life cycles of two recently observed cyclones. The analysi...

REASON FOR PERFORMING STUDY Foals stand and walk immediately after birth, but insight into the subsequent longitudinal development of their gait kinetics in the early juvenile phase and the possible influence of osteochondrosis thereon is lacking. OBJECTIVES To quantify gait kinetics in foals during the first half year of life, taking into account their osteochondrosis status. STUDY DESIGN ...
