The effects of assisted and resisted plyometric training on jump height and sprint performance among physically active females
2021
The aim of the present study was to compare the effects of assisted and resisted plyometric jump training on jump height, sprint performance (acceleration (0-20m), maximum speed (30-40m) and 40m sprint time) among physically active females. Fifty-six participants (age: 21.1 ± 1.7 years; body mass: 64.2 ± 7.0 kg; height: 168.0 ± 5.6 cm) were randomly allocated to either an assisted (n = 16) or resisted training group (n = 17), or a control group (n = 14). Nine participants dropped out during the intervention. The training sessions consisted of three different plyometric jump exercises over an eight-week period, while the control group continued their normal training routine. The results reve…
Capsular bag shrinkage after implantation of a capsular bending or capsular tension ring.
2005
To evaluate the influence of a capsular bending ring (CBR) or tension ring (CTR) on capsular bag shrinkage.Department of Ophthalmology, Johannes Gutenberg-University, and Department of Medical Biometry, Epidemiology and Informatics, University of Mainz, Mainz, Germany.In 92 eyes of 92 patients, a capsular measuring ring (CMR) was implanted after phacoemulsification to measure capsular bag size in vivo. Patients were randomized into 3 groups: The first received a CMR and CBR, the second received a CMR and CTR, and the third received a CMR alone. Measurements were performed preoperatively, intraoperatively, during the first 3 postoperative days, and after 1 and 3 months. Preoperative biometri…
How Do Cancer Registries in Europe Estimate Completeness of Registration?
2008
Summary Objectives: Several methods for estimating completeness in cancer registries have been proposed. Little is known about their relative merits. Before embarking on a systematic comparison of methods we wanted to know which indicators were currently in use and whether there had been comparative investigations of estimation methods. Methods: We performed a survey among European cancer registries asking which methods for estimating completeness they used and whether they had performed comparisons of methods. Results: One hundred and ninety-five European cancer registries were contacted after identification using membership directories of the European Network of Cancer Registries (ENCR) a…
“The sound of affect”: Age differences in perceiving valence and arousal in music and their relation to music characteristics and momentary mood
2018
Throughout life, music plays an important role in individuals’ everyday affective experiences. Previous findings suggest that preferences for, and perceptions of, music with distinct affective qualities might differ for individuals from different age groups. To date, however, evidence from age-comparative studies across adulthood is rare and little is known about the mechanisms that contribute to age differences in music perception. In an age-heterogeneous sample ranging from adolescence to old adulthood ( n = 50; 12–75 years), we investigated differences in affect perceptions of 147 sounds and 465 songs of various musical styles and dates of origin, as well as the respective roles of musi…
Physical education teachers in motion: an account of attrition and area transfer
2013
Background: Teacher turnover has been identified as a major problem that represents instability in teaching. Teacher turnover can be divided into three components: attrition means that the teacher is leaving the profession; area transfer means that the teacher is changing his/her subject area and migration means that the teacher is moving from one school to another. The single most important concern is teacher attrition. Attrition is particularly high among teachers in their first five years of service. Although extensive research has been carried out on teacher attrition, no single study exists which comprehensively analyses the attrition of physical education (PE) teachers.Purpose: The pu…
Age Differences in Learning from Instructional Animations
2015
Summary: The present study tests the effects of the decline of executive functions and spatial abilities with aging on the comprehension of a complex instructional animation. An animation of a piano mechanism was presented individually to 33 young adults and 31 elderly participants. Two presentation speeds of the animation (normal and slow) were compared in a 2×2 experimental design. Eye movements were recorded during the learning time. Then, four executive function tests (inhibition, shifting, updating, and processing speed) and a spatial ability test (differential aptitude test) were undertaken by each participant. Results showed that the comprehension of animations was significantly affe…
Cortical responses of infants with and without a genetic risk for dyslexia
1999
We studied auditory event-related potentials (ERP) in newborns and 6-month-old infants, about half of whom had a familial risk for dyslexia. Syllables varying in vowel duration were presented in an oddball paradigm, in which ERPs to deviating stimuli are assumed to reflect automatic change detection in the brain. The ERPs of newborns had slow positive deflections typical of their age, but significant stimulus and group effects were found only by the age of 6 months. In both groups, the responses to the deviant /ka/ were more positive than those to the standard /kaa/ stimuli, contrary to the findings of adult ERPs to duration changes. The results also suggested differences in brain activatio…
Associations between personality, sports participation and athletic success. A comparison of Big Five in sporting and non-sporting adults
2018
Abstract The present study investigates whether the Big Five personality traits are different among diverse sports populations. A sample of 881 male athletes and non-athletes completed a self-report questionnaire measuring their personality traits. The Exploratory Structure Equation Modeling (ESEM) approach is adopted to test measurement invariance and mean differences among groups. The results indicate that athletes who had experienced the most success in their sport scored higher than non-athletes in each personality dimension of the Big Five, with the exception of openness, while less successful athletes scored higher than non-athletes only in extraversion and agreeableness. The more suc…
Maladaptive and adaptive emotion regulation through music a behavioral and neuroimaging study of males and females
2015
Music therapists use guided affect regulation in the treatment of mood disorders. However, self-directed uses of music in affect regulation are not fully understood. Some uses of music may have negative effects on mental health, as can non music regulation strategies, such as rumination. Psychological testing and functional magnetic resonance imaging (fMRI) were used explore music listening strategies in relation to mental health. Participants (n = 123) were assessed for depression, anxiety and Neuroticism, and uses of Music in Mood Regulation (MMR). Neural responses to music were measured in the medial prefrontal cortex (mPFC) in a subset of participants (n = 56). Discharge, using music to…
Mate preferences in Argentinean transgender people
2018
Transgender people provide a unique opportunity to examine the effect of biological sex versus gender identity on mating preferences. This study aimed at identifying the mate characteristics that are most and least valued by transgender people and at examining to what extent their biological sex or their gender identity determined their mate preferences. A convenience sample of 134 male‐to‐female (MTF) and 94 female‐to‐male (FTM) individuals from Argentina rated Buss's list of 18 mate attributes. Compared to FTM, MTF individuals placed significantly more emphasis on attractiveness and socioeconomic status, whereas FTM, more than MTF individuals, valued partners with a dependable character. …
