The predictive value of exercise testing for survival among 75-year-old men and women
2006
All 75-year-olds born in 1914 and living in the city of Jyväskylä, central Finland (n=388) were invited to study the predictive value of exercise test for mortality. Subjects who entered the laboratory (n=295) were to have a standard pre-test evaluation and perform a cycle ergometer exercise test. Subjects with complete background, exercise-test status and mortality data (n=282) were divided into three groups according to exercise-test status: a non-exercise test group (n=79), an exercise-test termination group (n=95), and an exercise-test completion group (n=108). Mortality was followed up for 9 years. The multivariate hazard ratio (HR) for death among the non-exercise test group compared …
Longitudinal Physical Activity, Body Composition, and Physical Fitness in Preschoolers
2017
Purpose: This study aimed to investigate longitudinal associations of objectively measured physical activity (PA) and sedentary behavior (SB) with body composition and physical fitness at a 12-month follow-up in healthy Swedish 4-yr-old children. Methods: The data from the population-based MINISTOP trial were collected between 2014 and 2016, and this study included the 138 children who were in the control group. PA and SB were assessed using the wrist-worn ActiGraph (wGT3x-BT) accelerometer during seven 24-h periods and, subsequently, defined as SB, light-intensity PA, moderate-intensity PA, vigorous-intensity PA (VPA), and moderate-to-vigorous PA (MVPA). Body composition was measured using…
Health-related quality of life and physical activity in persons at high risk for type 2 diabetes
2008
The aim of this study was to compare the health-related quality of life (HRQOL) of persons at risk for type 2 diabetes to that of the Finnish general population. In addition, the associations between physical activity and HRQOL at-risk persons were studied.One hundred thirty-two at-risk persons were recruited from health care centres in Central Finland. Participants filled out questionnaires including demographic characteristics, HRQOL (SF-36), frequency of vigorous physical activity (or =2 times a week, once a week, less than once a week) and comorbidities.HRQOL of at-risk persons differed significantly from that of the Finnish population in four of the eight dimensions of SF-36. Compared …
Prevalence of sarcopenia and associated factors in the healthy older adults of the Peruvian Andes
2016
Aim To assess the prevalence of sarcopenia and associated factors in a population of older people living in a rural area of the Peruvian Andes. Materials and methods The study concerned 222 people aged ≥65 years. Sarcopenia was diagnosed on the basis of skeletal muscle mass, measured using bioimpedance analysis, and gait speed, measured with the 4-m walking test, as recommended by the International Working Group on sarcopenia. Self-reported physical activity, the Short Physical Performance Battery, and the Six-Minute Walking Test also contributed information on participants’ physical performance status. Disabilities were investigated by assessing participants’ self-reported difficulties in …
Leisure-Time Physical Activity and Psychological Well-Being in University Students
2012
An analysis of psychological well-being (self-esteem and subjective vitality) of 639 Spanish university students was performed, while accounting for the amount of leisure-time physical activity. The Spanish versions of the Rosenberg Self-Esteem Scale and Subjective Vitality Scale were employed. Participants were divided into four groups (Low, Moderate, High, and Very high) depending on estimation of energy expenditure in leisure-time physical activity. Men and women having higher physical activity rated higher mean subjective vitality; however, differences in self-esteem were observed only in men, specifically between Very high and the other physical activity groups.
Results from Finland’s 2014 Report Card on Physical Activity for Children and Youth
2014
The Finnish 2014 Report Card on Physical Activity (PA) for Children and Youth is the first assessment of Finland’s efforts in promoting and facilitating PA opportunities for children and youth using the Active Healthy Kids Canada grading system. The Report Card relies primarily on research findings from 6 Research Institutes, coordinated by the University of Jyväskylä. The Research Work Group convened to evaluate the aggregated evidence and assign grades for each of the 9 PA indicators, following the Canadian Report Card protocol. Grades from A (highest) to F (lowest) varied in Finland as follows: 1) Overall physical activity—fulfillment of recommendations (D), 2) Organized sport participat…
Measuring Motor Skills in Finnish Children with Intellectual Disabilities
2013
This investigation examined differences in motor skill development between Finnish children (12 boys, 8 girls) with mild intellectual disability and typically developing Finnish children between the ages of 7 and 11 years. Ulrich's Test of Gross Motor Development (TGMD) assessed the performances of 20 children with intellectual disability and an age- and sex-matched sample of 20 children without disabilities. Videotaped performances were assessed by the authors who were very familiar with the TGMD–2. The group with intellectual disability performed at a statistically significantly lower level on the Gross Motor Quotient, Locomotor, and Object Control subtests of TGMD–2, compared to the gro…
The early motor milestones in infancy and later motor skills in toddlers: a structural equation model of motor development.
2006
The relationship between the achievement of early motor milestones in infancy and later motor development was studied in 130 children with (N = 66, 35 male/31 female) and without (N = 64, 31 male/35 female) familial risk for dyslexia. A structured parental questionnaire was used to assess motor development in infancy, and the Movement Assessment Battery for Children was used to assess motor skills at age 3.5 years. No differences were found at the group level and therefore the structural equation model was constructed by entering both groups simultaneously. An Early Body Control factor, computed from the infant data, explained 38% of the variance of the Gross Motor Skills factor at the age …
Early emergence of deviant frontal fMRI activity for phonological processes in poor beginning readers.
2010
Phonological awareness refers to the ability to perceive and manipulate the sound structure of language and is especially important when children learn to read. Poor phonological awareness is considered the major cause for the emergence of reading difficulties. In this functional magnetic resonance imaging (fMRI) study, we examined the brain correlates of phonological processing in young beginning readers (aged 8.3+/-0.4 y, 2nd grade) with poor (25th percentile) or normal, age-appropriate reading skills (40th percentile) using a covert reading and mental letter substitution task. Letter substitution in words and nonwords induced pronounced activity in a left frontal language network related…
Acetaldehyde self-administration by a two-bottle choice paradigm: Consequences on emotional reactivity, spatial learning, and memory
2015
Abstract Acetaldehyde, the first alcohol metabolite, is responsible for many pharmacological effects that are not clearly distinguishable from those exerted by its parent compound. It alters motor performance, induces reinforced learning and motivated behavior, and produces different reactions according to the route of administration and the relative accumulation in the brain or in the periphery. The effective activity of oral acetaldehyde represents an unresolved field of inquiry that deserves further investigation. Thus, this study explores the acquisition and maintenance of acetaldehyde drinking behavior in adult male rats, employing a two-bottle choice paradigm for water and acetaldehyd…
