Preparedness for landing after a self-initiated fall.

2012

A startling auditory stimulus (SAS) causes a faster execution of voluntary actions when applied together with the imperative signal in reaction time tasks (the StartReact effect). However, speeding up reaction time may not be the best strategy in all tasks. After a self-initiated fall, the program for landing has to be time-locked to foot contact to avoid damage, and therefore advanced execution of the program would not be convenient. We examined the effects of SAS on the landing motor program in 8 healthy subjects that were requested to let themselves fall from platforms either 50 or 80 cm high at the perception of a visual imperative signal and land on specific targets. In trials at rand…

MAGAM II – prospective observational multicentre poisons centres study on eye exposures caused by cleaning products

Objective: Local effects on the eye following cleaning product exposures are frequently reported. According to EU chemicals legislation many cleaning products are labelled with Hazard Phrase 318 in...

Brain Slow Potentials Reflecting Successful Shooting Performance

1995

Preparatory brain activity from frontal, centro-lateral, and occipital areas were recorded from top-level rifle shooters during shooting performance. The aim of the study was to examine the relation of brain slow potentials to qualitative (rifle holding) and quantitative (hit) aspects of superior shooting performance. For this purpose, a typology of slow potentials (SPs) was developed. The resulting SP types were used for unraveling the associations between the electrocortical activity and behavioral output. The main finding was that frontal positivity was associated with successful performance, but only if the central-right SP was more negative than the central-left one. This finding was e…

The effects of a roundtrip trans-American jet travel on physiological stress, neuromuscular performance, and recovery.

2016

The purpose was to examine the effects of a round trip trans-American jet travel on performance, hormonal alterations, and recovery. Ten matched pairs of recreationally trained men were randomized to either a compression group (COMP) ( n = 10; age: 23.1 ± 2.4 yr; height: 174.8 ± 5.3 cm; body mass: 84.9 ± 10.16 kg; body fat: 15.3 ± 6.0%) or control group (CONT) ( n = 9; age: 23.2 ± 2.3 yr; height: 177.5 ± 6.3 cm; weight: 84.3 ± 8.99 kg; body fat: 15.1 ± 6.4%). Subjects flew directly from Hartford, CT to Los Angeles, CA 1 day before a simulated sport competition (SSC) designed to create muscle damage and returned the next morning on an overnight flight back home. Both groups demonstrated jet…

The Effect of Color on the Use of Electronic Body Protectors in Taekwondo Matches

2016

This study investigated the relationship between the color protector and success in taekwondo combats in the qualification championships, when electronic body protectors were used. Moreover, it analyzed the confounding effect of a participant being a top-ranked athlete in the 2012 London Olympic Games, in a sample of 462 matches. Results from the entire sample showed a non-significant relationship between the combat outcome and the winner’s color electronic protector. At the level of the tournament, the results showed a significant relationship between wearing a red electronic protector and winning the combat in the Asian and the European qualification tournaments. For gender and weight ca…

Analogical reasoning and aging: the processing speed and inhibition hypothesis.

2014

This study was designed to investigate the effect of aging on analogical reasoning by manipulating the strength of semantic association (LowAssoc or HighAssoc) and the number of distracters' semantic analogies of the A:B::C:D type and to determine which factors might be responsible for the age-related differences on analogical reasoning by testing two different theoretical frameworks: the inhibition hypothesis and the speed mediation hypothesis. We compared young adults and two groups of aging people (old and old-old) with word analogies of the A:B::C:D format. Results indicate an age-related effect on analogical reasoning, this effect being greatest with LowAssoc analogies. It was not asso…

Developmental trends in children's pretend play.

1991

The developmental trends in pretend play were investigated in children 2-6 years of age (18 in each of five age groups) by examining changes in pretend action and speech separately. Play behaviour was assessed by using a selected set of Duplo Lego toys. Interest focused on occurrence of decentration, decontextualization and integration at different age levels. The proportions of decentred and decontextualized acts, action integrations and play themes, increased linearly with age. Changes in substitutive and inventive actions were, however, more minor than expected. Single-scheme combinations did not reveal any essential aspect of the development of children's symbolic competence. In this se…

Causalidad en salud laboral: el caso ardystil

1995

ResumenEl establecimiento de relaciones causa-efecto ha sido y sigue siendo objeto de debate en epidemiología. La naturaleza observacional de la investigación epidemiológica dificulta el reconocimiento de estas relaciones. En este contexto, se han propuesto diferentes modelos para explicar las relaciones causales en los procesos de salud y enfermedad, desde el modelo determinista puro defendido por los postulados de Koch, que requiere la aceptación de relaciones unicausales, pasando por otras explicaciones que asumen la naturaleza multicausal de los problemas de salud en la población. En Salud Laboral se debe disponer también de modelos explicativos y criterios consensuados para valorar las…
