Plyometric training is a popular method utilized by strength and conditioning professionals to improve aspects of functional strength. The purpose of this study was to explore the influence of extrinsic verbal cueing on the specificity of jumping movements. Thirteen participants (age: 23.4 ± 1.9 yr, body height: 170.3 ± 15.1 cm, body mass: 70.3 ± 23.8 kg,) performed four types of jumps: a depth...

Recently we found that the marked behavioral difference between isolated and grouped rats occurred under foot shock situations by measuring frequency of jumping behavior in rats (Nishikawa and Tanaka, 1978). We also postulated by the results of methamphetamine administration and the behavioral findings that catecholaminergic hyperactivity especially receptor supersensitivity might play a role i...

[1] A dynamically driven mechanism occurring above severe thunderstorms is described, which can explain the jumping cirrus phenomenon. A three-dimensional, nonhydrostatic cloud model is used to perform numerical simulation of a supercell that occurred in Montana in 1981. The jumping cirrus phenomenon is reproduced in the simulated storm. Analysis of the model results shows that the jumping cirr...

BACKGROUND Certain sites have gained notoriety as 'hotspots' for suicide by jumping. Structural interventions (e.g. barriers and safety nets) have been installed at some of these sites. Individual studies examining the effectiveness of these interventions have been underpowered. METHOD We conducted a meta-analysis, pooling data from nine studies. RESULTS Following the interventions, there w...

A Preble's meadow jumping mouse (Zapus hudsonius preblei) parasitized by five grey flesh fly (Wohlfahrtia vigil) larvae was discovered at the United States Air Force Academy in Colorado Springs, Colorado (USA), in June 1998. This is the first documented case of grey flesh fly parasitism of jumping mice (Family Dipodidae). The lesion was approximately 6 mm wide and was partially hidden under a m...

The aim of this study was to investigate the differences in loaded and unloaded jump performances between different age categories of top-level volleyball players from the same club. Forty-three volleyball players were divided into four age groups: under-17, under-19, under-21 and professional. Vertical jumping height for squat jump (SJ), countermovement jump (CMJ) and CMJ with arm swing (CMJa)...

The aim was to analyze the effect of four trainings on the neuromuscular adaptation of the knee extensors muscles, and particularly the connection with neuromuscular fatigue and exercise-induced muscle damage (EIMD). The subjects were healthy untrained men (age 20.8 1.2 years, n=11). The four jumping endurance trainings (JETs) were repeated every 3 days and each consisted of five series of 20 j...

These experiments show that vision can be improved by manipulating mind-sets. In Study 1, participants were primed with the mind-set that pilots have excellent vision. Vision improved for participants who experientially became pilots (by flying a realistic flight simulator) compared with control participants (who performed the same task in an ostensibly broken flight simulator). Participants in...

The aim of this article is to describe a structuralised cognitive group therapy - the meta-cognitive training for schizophrenia patients, developed in 2005 by S. Moritz and T. S. Woodward. This method is based on research results regarding cognitive biases observed in schizophrenia patients, which were briefly described. The metacognitive training could be administered by a therapist with group...
