Physical Activity-Related Profiles of Female Sixth-Graders Regarding Motivational Psychosocial Variables: A Cluster Analysis Within the CReActivity P…
2020
IntroductionAdolescents’ physical activity (PA) behavior can be driven by several psychosocial determinants at the same time. Most analyses use a variable-based approach that examines relations between PA-related determinants and PA behavior on the between-person level. Using this approach, possible coexistences of different psychosocial determinants within one person cannot be examined. Therefore, by applying a person-oriented approach, this study examined (a) which profiles regarding PA-related psychosocial variables typically occur in female sixth-graders, (b) if these profiles deliver a self-consistent picture according to theoretical assumptions, and (c) if the profiles contribute to t…
Heart rate variability and self-control–A meta-analysis
2016
We read the commentary on our meta-analysis with great interest and we greatly appreciate that the authors developed suggestions for further research on heart rate variability (HRV) and self-control. While we mostly support these suggestions, we believe that it is necessary to clarify some points raised with respect to our meta-analysis. The first point brought up by the authors of the commentary is the focus of our meta-analysis on HRV instead of vagal tone and the inclusion of studies using the standard deviation of RR intervals (SDNN). They argue that only vagal tone and HRV metrics reflecting vagal tone are expected to be linked to self-control according to both the Neurovisceral Integr…

Functional Information, Biomolecular Messages and Complexity of BioSequences and Structures
2010
In the quest for a mathematical measure able to capture and shed light on the dual notions of information and complexity in biosequences, Hazen et al. have introduced the notion of Functional Information (FI for short). It is also the result of earlier considerations and findings by Szostak and Carothers et al. Based on the experiments by Charoters et al., regarding FI in RNA binding activities, we decided to study the relation existing between FI and classic measures of complexity applied on protein-DNA interactions on a genome-wide scale. Using classic complexity measures, i.e, Shannon entropy and Kolmogorov Complexity as both estimated by data compression, we found that FI applied to pro…

Velocity-based resistance training: do women need greater velocity loss to maximize adaptations?
2021
Abstract Purpose Men and women typically display different neuromuscular characteristics, force–velocity relationships, and differing strength deficit (upper vs. lower body). Thus, it is not clear how previous recommendations for training with velocity-loss resistance training based on data in men will apply to women. This study examined the inter-sex differences in neuromuscular adaptations using 20% and 40% velocity-loss protocols in back squat and bench press exercises. Methods The present study employed an 8-week intervention (2 × week) comparing 20% vs. 40% velocity-loss resistance training in the back squat and bench press exercises in young men and women (~ 26 years). Maximum strengt…
Zivju sabiedrības sezonālās izmaiņas Liepājas ostas akvatorijā saimnieciskās darbības ietekmē
2021
Darbā analizēta Liepājas ostas akvatorijas zivju sabiedrība, tās sezonālās izmaiņas, un to galvenie ietekmējošie faktori. Datu ievākšana, veicot kontrolzveju ar zinātniskajiem tīkliem trīs gadu garumā, četrās sezonās (rudens, ziema, pavasaris, vasara) sniedz precīzu ieskatu par zivju sugu sezonālajām izmaiņām. Papildus ievāktie hidroloģiskie dati ļauj spriest par galvenajiem ietekmējošajiem faktoriem. Darbu vēl unikālāku padara vienā no pētījuma posmiem veiktā ostas padziļināšana, izceļot grunti, kas ļauj ne tikai novērtēt papildus faktoru ietekmi uz zivju sugu mainību, bet izdarīt secinājumus arī par saimnieciskās darbības ietekmi uz zivju sabiedrību akvatorijā, novērot ostas ekosistēmas a…
Sport participation and loneliness in adolescents: the mediating role of perceived social competence
2013
Published version of an article in the journal: Current Psychology. Also available from the publisher at: http://dx.doi.org/10.1007/s12144-013-9174-5 Young people perceive loneliness as a distressing emotional experience associated with sadness and boredom. Also, feelings of loneliness may be associated with psychosocial and emotional problems during adolescence. The aim of this study was to investigate whether perceived social competence mediated the cross-sectional relationship between sport participation and loneliness in young people when controlling for age, sex, shyness, and non-organized physical activity. This cross-sectional study consisted of 2,055 pupils (995 boys and 1,060 girls…
Effects of Using Standing Versus Sitting Workstations on the Well-Being at Work of Software Professionals
2016
Although people admittedly are one of the most valuable assets of many software companies, relatively little academic research has been done from the well-being at work aspect of software professionals. This intervention study aims to address this gap in prior research by examining the potential effects of using standing instead of sitting workstations on the well-being at work of software professionals in terms of physical activity, mental alertness, and stress. The two measurements before and after the intervention were conducted in June and September 2015 for 29 employees of a local site of a large Finnish software company by using questionnaires and the Firstbeat Lifestyle Assessment se…
The effect of contextual variables on the attacking style of play in professional soccer
2021
The aim of this paper was to investigate the interactive effects of contextual variables on the attacking style of play in professional soccer. 5849 team possessions from 40 random matches from Spanish La Liga and English Premier League 2017-2018 were analysed by means of multidimensional observation. Multilevel multivariate logistic regressions showed that home teams had higher odds of implementing fast attacks (p<.05) and lower odds of implementing direct attacks (p<.05) than combinative attacks. High-ranked teams presented lower odds of using direct attacks (p<.05) than combinative attacks in comparison with low-ranked teams, while playing against high-ranked opponents decreased the prob…
