AIM Different jumping strategies can be used during plyometric training. Understanding how manipulating variables such as the counter-movement, flexion amplitude, the drop and the load could influence neuromuscular adaptation would be beneficial for coaches and athletes. The purpose of this study was to analyze how these variations in the vertical jump influenced kinematic and kinetic parameter...

The jump number of a partial order P is the minimum number of incomparable adjacent pairs in some linear extension of P. The jump number problem is known to be NP {hard in general. However some particular classes of posets admit easy calculation of the jump number. The complexity status for interval orders still remains unknown. Here we present a heuristic that, given an interval order P , gene...

With the application of automation, a horse jump can be controlled with the push of a button, or even a remote control. This enables the rider to adjust the jump to suit their needs while still on their horse. The objective of this work is to design and build a wireless remote motor controller which will be applied to a prototype horse jump. The user will be able to control the forward and reve...

Thoroughbred jump racing sits in the spotlight of contemporary welfare and ethical debates about horse racing. In Australia, jump racing comprises hurdle and steeplechase races and has ceased in all but two states, Victoria and South Australia. This paper documents the size, geography, composition, and dynamics of Australian jump racing for the 2012, 2013, and 2014 seasons with a focus on debat...

A new integral with respect to an integer-valued random measure is introduced. In contrast the finite variation ubiquitous in semimartingale theory, closed under stochastic integration, composition, and smooth transformations. The gives rise a previously unstudied class of pure-jump processes – sigma-locally processes. As application, it shown that every X has unique decomposition X=X0+Xqc+Xdp,...

This study analyzed modulation of jump performance and intralimb coordination throughout a 30 s vertical jump test. Twenty male athletes performed the test on a force plate while also undergoing kinematic analysis. Jump height and coordination by continuous relative phase (CRP) were analyzed. Results showed reduction of jump height during the test. No changes were observed in CRP for thigh-leg ...

We investigate “jump memory” using an extensive data base of short-term S&P 500 Index options. Jump memory refers to the attenuation of the implied jump intensity and magnitude parameters following a jump event. Behavioral and rational explanations for parameter attenuation are posited. A genetic algorithm is used to obtain implied parameter estimates. The pricing accuracy of the jump-diffusion...
