Physical activity and sleep profiles in Finnish men and women
2013
Background. Physical activity (PA) and sleep are related to cardiovascular diseases (CVD) and their risk factors. The interrelationship between these behaviors has been studied, but there remain questions regarding the association of different types of PA, such as occupational, commuting, and leisure time to sleep, including quality, duration and sufficiency. It is also unclear to what extent sleep affects peoples’ PA levels and patterns. Our aim is to investigate the interrelationship between PA and sleep behaviors in the Finnish population, including employment status and gender. Methods. The study comprised population based data from the FINRISK 2012 Study. A stratified, random sample of…
Factors explaining the physical activity of young adults: the importance of early socialization.
2007
As a part of the large project Cardiovascular Risk in Young Finns, the purpose of the present study was to examine how adult physical activity is influenced by early physical activity and current social and health-related factors. A total of 2411 children and adolescents aged 9, 12, 15 and 18 years were randomly selected from five university towns and their rural surroundings in 1980. They were followed up for 12 years by means of questionnaires. In 1992 they were 21, 24, 27 and 30 years old. The results showed that early physical activity and current social and health-related behaviours were significantly related to the level of adult physical activity. Multivariable analyses indicated tha…
Long-term leisure time physical activity and properties of bone: A twin study
2009
Effects of physical activity on bone properties, when controlled for genetic effects, are not fully understood. We aimed to study the association between long-term leisure time physical activity (LTPA) and bone properties using twin pairs known to be discordant for leisure time physical activity for at least 30 yr. Volumetric BMD and geometric properties were measured at the tibia shaft and distal end using pQCT in 16 middle-aged (50-74 yr) same-sex twin pairs (seven monozygotic [MZ] and nine dizygotic [DZ] pairs) selected from a population-based cohort. Paired differences between active and inactive co-twins were studied. Active members of MZ twin pairs had larger cortical bone cross-secti…
The Effect of Nitrazepam on Manual Skill, Grip Strength, and Reaction Time with Special Reference to Subjective Evaluation of Effects on Sleep
1978
The effects of 5 and 10 mg oral nitrazepam doses on manual skills, grip strength, and reaction time 8 hours after ingestion of the drugs were studied in 34 healthy female volunteers aged 19-22 years. 5 mg nitrazepam caused a slight but insignificant decrease in psychomotor skills. With 10 mg psychomotor skills were influenced significantly. Grip strength and reaction time were not influenced either by the 5 or 10 mg doses. The investigators corroborate the value of the established effects of nitrazepam as a hypnotic, but recommend that caution should be excercised in prescribing the drug as a hypnotic (especially in doses exceeding 5 mg) to work-aged subjects as there is a risk of significa…
Direction-dependent activation of the insular cortex during vertical and horizontal hand movements
2016
International audience; The planning of any motor action requires a complex multisensory processing by the brain. Gravity - immutable on Earth - has been shown to be a key input to these mechanisms. Seminal fMRI studies performed during visual perception of falling objects and self-motion demonstrated that humans represent the action of gravity in parts of the cortical vestibular system; in particular, the insular cortex and the cerebellum. However, little is known as to whether a specific neural network is engaged when processing non-visual signals relevant to gravity. We asked participants to perform vertical and horizontal hand movements without visual control, while lying in a 3T-MRI sc…
Comorbidity and physical activity in people with paraplegia: a descriptive cross-sectional study.
2017
Descriptive cross-sectional study. The study was conducted in the Spinal Cord Injury Unit of the University Vall d’Hebron Hospital and in the Physical Education and Sports Department of the University of Valencia. The aim of this study was to quantify the presence of comorbidities in spinal cord injury (SCI) subjects who did or did not perform regular physical activity (PA) and to identify the relationship between PA and the level of comorbidity. The sample consisted of patients with complete motor SCI (T2–T12), who were fitted with an accelerometer attached to the non-dominant wrist for a period of 1 week. The clinical and blood analytic variables were selected by an expert panel. In the e…
Associations in physical activity and sedentary behaviour among the immigrant and non-immigrant US population
2020
BackgroundImmigrants are at a higher risk of poor mental and physical health. Regular participation in physical activity (PA) and low levels of sedentary time are beneficial for both these aspects of health. The aim was to investigate levels and trends in domain-specific PA and sedentary behaviour in the US. immigrant compared with non-immigrant populations.MethodsFrom the 2007–2016 National Health and Nutrition Examination Survey (NHANES), a total of 25 142 adults (≥18 years) were included in this analysis. PA and sedentary behaviour time were assessed by a questionnaire.ResultsTransit-related PA showed downward linear trends in young immigrant adults (ptrend=0.006) and middle-aged non-imm…
Genetic and environmental influences on longitudinal changes in leisure-time physical activity from adolescence to young adulthood.
2013
The aim of this study was to estimate genetic and environmental influences on the longitudinal evolution of leisure-time physical activity habits from adolescence to young adulthood. Data were gathered at four time points, at mean ages 16.2, 17.1, 18.6, and 24.5 years. At baseline, the sample comprised 5,216 monozygotic and dizygotic twins, born 1975–1979, and, at the last follow-up point, of 4,531 monozygotic and dizygotic twins. Physical activity volume was assessed as frequency of leisure-time physical activity and participants were categorized into three groups: inactive, moderately active, and active. Genetic and environmental influences were estimated using a multivariate, longitudina…
Momentary Affect Predicts Bodily Movement in Daily Life: An Ambulatory Monitoring Study
2010
There is converging evidence that physical activity influences affective states. It has been found that aerobic exercise programs can significantly diminish negative affect. Moreover, among healthy individuals, moderate levels of physical activity seem to increase energetic arousal and positive affect. However, the predictive utility of affective states for bodily movement has rarely been investigated. In this study, we examined whether momentarily assessed affect is associated with bodily movement in everyday life. Using a previously published data set (Schwerdtfeger, Eberhardt, & Chmitorz, 2008), we reanalyzed 12-hr ecological momentary assessment (EMA) data from 124 healthy volunteer…
Validation of the Dutch Eating Behavior Questionnaire (DEBQ) in a sample of Spanish women
2014
Contains fulltext : 124145.pdf (Publisher’s version ) (Closed access) The Dutch Eating Behavior Questionnaire (DEBQ) was developed to measure eating styles that may contribute to or attenuate the development of overweight. It comprises three scales that measure emotional, external and restrained eating. The main goal of this study is to evaluate the internal structure of the Spanish version of the DEBQ using updated psychometric techniques in a sample of women. A sample of 647 Spanish females answered the questionnaire. Both exploratory structural equation modeling and confirmatory factor analysis were used to evaluate the factor structure of the DEBQ. Reliabilities were estimated with Cron…
