Voluntary contractions underestimate peak muscle activity in drop jumps
International BiomechanicsMaximal voluntary isometric contractions (MVIC) are a common method to normalize electromyographic amplitude into standardized units of %MVIC. However, in 60% of drop jump research using an MVIC in 2018–2023, supramaximal activation or activation greater

ASSOCIATION BETWEEN MUSCLES’ CONTRACTILE PROPERTIES AND JUMPING PERFORMANCE IN GYMNASTS
Science of Gymnastics Journal, 2020 This study examined the association between muscles’ contractile properties and jumping skill performance in gymnasts. Thirty-nine internationally experienced female (56%) and male (44%) gymnasts participated in the study.

Acute Effect of Drop Jumping on Throwing Performance
Journal of Strength and Conditioning Research, 2009 The purpose of the present study was to investigate the acute effect of drop jumping on throwing performance. Eight men and 8 women, moderately trained subjects with basic shot put skills, performed 3 squat underhand front shot throws after a short standard warm-up.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Jump Bidding and Overconcentration in Decentralized Simultaneous Ascending Auctions [PDF]
A model of English auction that allows jump bidding is proposed. When two objects are sold separately via such English auctions, I construct an equilibrium such that bidders signal via jump bids, thereby forming rational expectations of the prices ...

FEBS Open Bio, EarlyView.TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.
