The relationship between loading history and proximal femoral diaphysis cross-sectional geometry
2017
Objectives We investigated the relationship between loading history and bone biomechanical properties used in physical activity reconstructions. These bone properties included bone bending and torsional strength (J), cortical area (CA), the direction of the major axis (theta angle), and element shape ratios determined from cross sections of standardized bone length. In addition, we explored the applicability of anatomically determined cross sections. Methods Our material consisted of hip and proximal thigh magnetic resonance images of Finnish female athletes (N = 91) engaged in high-jump, triple-jump, endurance running, swimming, power-lifting, soccer and squash; along with a group of activ…
Television in the bedroom and increased body weight: potential explanations for their relationship among European schoolchildren
2012
Summary Aims: A television in the bedroom is associated with measures of adiposity. We aimed to test if this association is mediated by any of (i) time spent watching television, (ii) sleep duration, (iii) physical activity level or (iv) consumption of soft drinks. Method: Data were from 7234 boys and girls aged 10–12 years in European countries involved in the EuropeaN Energy balance Research to prevent excessive weight Gain among Youth project (Belgium, Greece, Hungary, the Netherlands, Norway, Slovenia and Spain). Waist circumference, height and weight were measured. The presence of a bedroom television, television viewing time, sleep duration, physical activity time and soft drink consu…
Dual Careers of Athletes During COVID-19 Lockdown
2021
This study aimed to investigate the student-athletes' capability to face the academic, sport, and social challenges during the coronavirus disease 2019 (COVID-19) lockdown and to disclose novel aspects of dual careers. A 32-item online survey encompassing demographic characteristics, sport and university engagement, support and dual-career benefits, physical activity, sitting time, and the time deemed necessary to recover the previous level of performance was developed. Four hundred sixty-seven student-athletes (males: 57%, females: 43%) from 11 countries, competing in 49 different sports (individual: 63.4%, team: 36.6%) at regional (17.5%), national (43.3%), and international (39.2%) level…
COVID-19 Confinement and Health Risk Behaviors in Spain
2021
The World Health Organization (WHO) has declared a world pandemic due to COVID-19. In response, most affected countries have enacted measures involving compulsory confinement and restrictions on free movement, which likely influence citizens' lifestyles. This study investigates changes in health risk behaviors (HRBs) with duration of confinement. An online cross-sectional survey served to collect data about the Spanish adult population regarding health behaviors during the first 3 weeks of confinement. A large sample of participants (
Prevalence and Correlates of Physical activity in a sample of UK adults observing social distancing during the COVID-19 pandemic
2020
ObjectiveTo investigate the levels and correlates of physical activity during COVID-19 social distancing in a sample of the UK public.MethodsThis paper presents analyses of data from a cross-sectional study. Levels of physical activity during COVID-19 social distancing were self-reported. Participants also reported on sociodemographic and clinical data. The association between several factors and physical activity was studied using regression models.ResultsNine hundred and eleven adults were included (64.0% were women and 50.4% of the participants were aged 35–64 years). 75.0% of the participants met the physical activity guidelines during social distancing. Meeting these guidelines during …
Rethinking children’s physical activity interventions at school: A new context-specific approach
2023
Physical activity is important for children’s health. However, evidence suggests that many children and adults do not meet international physical activity recommendations. Current school-based interventions have had limited effect on physical activity and alternative approaches are needed. Context, which includes school setting, ethos, staff, and sociodemographic factors, is a key and largely ignored contributing factor to school-based physical activity intervention effectiveness, impacting in several interacting ways.ConceptualizationCurrent programs focus on tightly-constructed content that ignores the context in which the program will be delivered, thereby limiting effectiveness. We prop…
A dual process model to predict adolescents’ screen time and physical activity
2021
OBJECTIVE: Many adolescents report a lack of physical activity (PA) and excess screen time (ST). Psychological theories aiming to understand these behaviours typically focus on predictors of only one behaviour. Yet, behaviour enactment is often a choice between options. This study sought to examine predictors of PA and ST in a single model. Variables were drawn from dual process models, which portray behaviour as the outcome of deliberative and automatic processes. DESIGN: 411 Finnish vocational school students (age 17-19) completed a survey, comprising variables from the Reasoned Action Approach (RAA) and automaticity pertaining to PA and ST, and self-reported PA and ST four weeks later. M…
Electrical Brain Activity and Its Functional Connectivity in the Physical Execution of Modern Jazz Dance
2020
Besides the pure pleasure of watching a dance performance, dance as a whole-body movement is becoming increasingly popular for health-related interventions. However, the science-based evidence for improvements in health or well-being through dance is still ambiguous and little is known about the underlying neurophysiological mechanisms. This may be partly related to the fact that previous studies mostly examined the neurophysiological effects of imagination and observation of dance rather than the physical execution itself. The objective of this pilot study was to investigate acute effects of a physically executed dance with its different components (recalling the choreography and physical …
Un campo científico en busca de visibilidad. Jornadas internacionales sobre la calidad de las revistas de Ciencias de la Actividad Física y el Deporte
2008
El campo de las Ciencias de la Actividad Física y el Deporte (CCAFD) en España necesita de actuaciones que contribuyan a mejorar la calidad de sus publicaciones periódicas. De esta manera las revistas pueden convertirse en órganos eficientes de comunicación y difusión del conocimiento científico creado por sus investigadores. En este trabajo se detalla la realización de las “Jornadas internacionales sobre la calidad de las revistas de ciencias de la actividad física y el deporte” celebradas en Valencia el 25 y 26 de octubre de 2007. Durante esos días se discutió sobre distintas visiones de la calidad de las revistas, ejemplos de gestión editorial y estrategias concretas de mejora. Con estas…
Feasibility of a Responsibility-Based Leadership Training Program for Novice Physical Activity Instructors
2021
Most coaches and instructors would like to teach more than just sport skills to their athletes and children. However, to promote athletes' or children's holistic development and teach them to take responsibility and lead, requires the coaches and instructors to first master the skills themselves. Therefore, feasible, high quality leadership training programs where coaches and physical activity instructors are taught to teach and share leadership are needed. The aim of the current study was to evaluate the feasibility of a leadership training program to optimize it and to determine whether to proceed with its evaluation. In the leadership training program, eight Finnish novice physical activ…
