Measurement errors when estimating the vertical jump height with flight time using photocell devices: the example of Optojump [PDF]
Biology of Sport, 2016 Common methods to estimate vertical jump height (VJH) are based on the measurements of flight time (FT) or vertical reaction force. This study aimed to assess the measurement errors when estimating the VJH with flight time using photocell devices in ...

Jumps in the Archimedean height [PDF]
Duke Mathematical Journal, 2019 We introduce a pairing on local intersection cohomology groups of variations of pure Hodge structure, which we call the asymptotic height pairing. Our original application of this pairing was to answer a question on the Ceresa cycle posed by R. Hain and D. Reed. (This question has since been answered independently by Hain.) Here we apply the pairing to

Determinants of joint stiffness and jumping height during drop jump
Physiological Reports, 2023 AbstractThe present study aimed to examine the effects of muscle‐tendon mechanical properties and electromyographic activity on joint stiffness and jumping height and to explore the determinants of joint stiffness and jumping height. Twenty‐nine males performed unilateral drop jumps at three drop heights (10, 20, and 30 cm) using only the ankle joint ...

Evaluation of a Torque-Driven Model of Jumping for Height [PDF]
Journal of Applied Biomechanics, 2006 This study used an optimization procedure to evaluate an 8-segment torque-driven subject-specific computer simulation model of the takeoff phase in running jumps for height. Kinetic and kinematic data were obtained on a running jump performed by an elite male high jumper.

Néron models and the height jump divisor [PDF]
Transactions of the American Mathematical Society, 2017 39 pages. The middle sections of the paper have been re-ordered for clarity. In addition, the results from Section 11 of the previous version have been removed, as they depend on some other results which are as yet unpublished.

Modeling and Error Analysis in Camera-Based Jump Height Measurement
Current Directions in Biomedical Engineering, 2022 Introduction: In this work, we use simulated data to quantify the different failure mechanisms of a previously presented low-cost jump height measurement system, based on widely available consumer smartphone technology.

Positivity of the Height Jump Divisor
International Mathematics Research Notices, 2017 We study the degeneration of semipositive smooth hermitian line bundles on open complex manifolds, assuming that the metric extends well away from a codimension two analytic subset of the boundary. Using terminology introduced by R. Hain, we show that under these assumptions the so-called height jump divisors are always effective.
