A Polygenic Risk Score for Hand Grip Strength Predicts Muscle Strength and Proximal and Distal Functional Outcomes among Older Women
2022
Purpose Hand grip strength (HGS) is a widely used indicator of overall muscle strength and general health. We computed a polygenic risk score (PRS) for HGS, and examined, whether it predicted muscle strength, functional capacity and disability outcomes. Methods Genome-wide association study summary statistics for HGS from the Pan-UK Biobank was utilized. PRSs were calculated in the Finnish Twin Study on Aging (N = 429 women, 63–76 years). Strength tests included HGS, isometric knee extension, and ankle plantar flexion strength. Functional capacity was examined with the Timed Up and Go, six-minute and 10-meter walk tests, and dual-task tests. Disabilities in the basic (ADL) and instrumental …

A school-based quasi-experimental intervention to improve students' motor competence and physical fitness
2022
Background Previous research has shown that school can be an influential context to promote students' physical activity engagement, physical fitness, and motor competence. The purpose of this study was to investigate the effectiveness of a 5-month-long intervention program that aimed to increase students' motor competence and physical fitness during school days. Methods A quasi-experimental intervention design with pre- and post-tests was implemented. Altogether 325 Finnish Grade 5 (Mage = 11.26, SD = .33) students from five schools participated in the study. At the beginning of the study, students were divided into experimental and control groups on purpose. The intervention consisted of t…
Cardiac cycle and respiration phase affect responses to the conditioned stimulus in young adults trained in trace eyeblink conditioning
2022
Rhythms of breathing and heartbeat are linked to each other as well as to rhythms of the brain. Our recent studies suggest that presenting the conditioned stimulus during expiration or during the diastolic phase of the cardiac cycle facilitates neural processing of that stimulus and improves learning an eyeblink classical conditioning task. To date, it has not been examined whether utilizing information from both respiration and cardiac cycle phases simultaneously allows even more efficient modulation of learning. Here we studied whether the timing of the conditioned stimulus to different cardiorespiratory rhythm phase combinations affects learning trace eyeblink conditioning in healthy you…
Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure: A pooled analysis of 1018…
2018
Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean dia…
Towards a scenario of virtual mental health environments for school-aged children
2017
This study explores student teachers’ future design scenarios focusing on promoting children’s mental health literacy through virtual reality (VR) environments. VR use is on the verge of many breakthroughs in several areas of lived experience. One such area pertains to educational contexts. Student teachers were chosen as the subjects of this study due to the likelihood that they will be the primary users and disseminators of these emerging technologies in educational contexts. The students created five types of future scenarios that contained different environments and activity modes, including those that are still not yet feasible to realize with current technological capabilities. The ai…
Online activity traces around a "Boston bomber"
2013
This paper describes traces of user activity around a alleged online social network profile of a Boston Marathon bombing suspect, after the tragedy occurred. The analyzed data, collected with the help of an automatic social media monitoring software, includes the perpetrator's page saved at the time the bombing suspects' names were made public, and the subsequently appearing comments left on that page by other users. The analyses suggest that a timely protection of online media records of a criminal could help prevent a large-scale public spread of communication exchange pertaining to the suspects/criminals' ideas, messages, and connections.
Sobre la recreación de coros trágicos en el teatro español contemporáneo
2019
El estudio de los coros dramáticos de la tragedia griega continúa presentando una serie de problemas en cuanto a su interpretación y función dentro de la acción dramática. El asunto se complica todavía más cuando abordamos adaptaciones y versiones libres del teatro contemporáneo, puesto que la introducción del coro resulta muy compleja al ser este considerado un elemento anacrónico. El propósito de este trabajo es el análisis de la renovación de la escena que se produce en España en el siglo XX, donde el teatro griego ejerce un peso fundamental, como demuestran las obras de Arcadio López Casanova (Orestes, 1960) y Maria Josep Ragué (Clitemnestra, 1985), tomadas aquí como corpus de estudio. …
