Validation of a method to measure total spontaneous physical activity of sedentary and voluntary running mice
2014
Running wheels are commonly used to stimulate physical activity of mice. To control the effects of physical activity on study results, it is important to measure the total activity (all movements) of both sedentary and running wheel stimulated mice.Because there was a lack of a validated system, we built a force-plate based system specifically for this purpose. The validity of the system and its variables (activity index, activity time and distance) were tested in calibration measurements and in situ by measuring the activity of eight mice both with and without running wheels. Four mice served as sedentary controls. Activity index adds changes in vertical reaction forces induced by moving m…
Changes in physical activity domains during the transition out of high school: Psychosocial and environmental correlates
2015
Background:This study examined changes in multiple physical activity domains during the transition out of high school and psychosocial and environmental determinants of these changes.Methods:A 1-year prospective study was designed. The baseline sample was composed of 244 last-year high school students (58.6% female) from Valencia, Spain. Follow-up rate was 46%. Physical activity and potential determinants were measured by the Global Physical Activity Questionnaire and other evaluated scales in 2 waves.Results:Total physical activity and active commuting (AC) decreased, respectively, by 21% and 36%, only in males. At time 1, access to car/motorbike (inverse), planning/psychosocial barriers (…
Predicting accelerometer-based physical activity in physical education and total physical activity: The Self-determination Theory approach
2019
The present study tested the motivational model of physical education (PE) including needs for competence, autonomy, social relatedness, intrinsic and extrinsic motivation, in-class moderate to vigorous physical activity (MVPA), and total MVPA. Participants were 490 (264 girls, 226 boys) Finnish elementary school students. The data were collected using accelerometers and questionnaires for a seven-day period during the fall semester 2017. The key findings were that 1) social relatedness associated with total MVPA via in-class MVPA in girls, whereas competence was linked to in-class MVPA through extrinsic motivation in boys, 2) competence was positively linked to extrinsic motivation in a si…
The effects of a 2-year individualized and family-based lifestyle intervention on physical activity, sedentary behavior and diet in children
2016
To investigate the effects of a long-term, individualized and family-based lifestyle intervention on physical activity, sedentary behavior and diet quality in children.We carried out a 2-year intervention study in a population sample of 506 children aged 6-8years in Finland in 2007-2012. We allocated the participants at baseline in the intervention and control group. We assessed physical activity and sedentary behavior by questionnaires and diet by food records.Total physical activity (+9min/d in intervention group vs. -5min/d in control group, p=0.001 for time*group interaction), unsupervised physical activity (+7min/d vs. -9min/d, p0.001) and organized sports (+8min/d vs. +3min/d, p=0.001…
Muscle Inactivity and Activity Patterns after Sedentary-Time Targeted Randomized Controlled Trial
2014
Purpose: Interventions targeting sedentary time are needed. We used detailed EMG recordings to study the short-term effectiveness of simple sedentary time-targeted tailored counseling on the total physical activity spectrum. Methods: This cluster randomized controlled trial was conducted between 2011 and 2013 (InPact, ISRCTN28668090), and short-term effectiveness of counseling is reported in the present study. A total of 133 office workers volunteered to participate, from which muscle activity data were analyzed from 48 (intervention, n = 24; control, n = 24). After a lecture, face-to-face tailored counseling was used to set contractually binding goals regarding breaking up sitting periods …
Psychosocial and environmental correlates of active commuting for university students.
2009
Abstract Objective To examine psychosocial and environmental correlates of active commuting to university (ACU) and explore its association with overall physical activity among college students. Methods The sample included 518 students (mean 22.4 years; 59.7% female) from two universities in Valencia, Spain. Weekly estimations of energy expenditure from ACU and total physical activity were obtained. Socio-economic status, self-efficacy, barriers to active transport, access to car and motorbike, access to public transport, walking and cycling facilities and distance to university were assessed. Data were collected April and May of 2009, using a self-administered survey. A structural equation…
A one-year follow-up of basic psychological need satisfactions in physical education and associated in-class and total physical activity
2020
This study examined basic psychological need satisfactions for competence, autonomy, and social relatedness in physical education (PE) and their contributions to accelerometer-based in-class and total moderate to vigorous physical activity (MVPA) across a one-year follow-up (T1). Participants were 523 students (girls 280, boys 243; mean age = 11.26 ± 0.31) and the data were collected using self-reports and waist-worn accelerometers. The key findings were: (a) competence and social relatedness need satisfaction at baseline (T0) predicted total MVPA at T1 via total MVPA at T0; (b) in-class MVPA at T0 predicted total MVPA at T1 via total MVPA at T0; (c) in-class MVPA was directly associated w…
Diet Macronutrient Composition, Physical Activity, and Body Composition in Soldiers During 6 Months Deployment
2018
Abstract Introduction Optimal diet together with good physical fitness maintains readiness and military performance during longer deployments. The purpose of this study was to describe changes in dietary macronutrient and energy intake, total physical activity and body composition during a 6-month deployment in South Lebanon. Furthermore, associations of diet macronutrient intake and physical activity on body composition were also studied. Materials and Methods Forty male soldiers kept a 3-day food diary and their body composition was measured via bioimpedance and ultrasonography. Total physical activity was evaluated by accelerometers in a subgroup of participants. Measurements were conduc…
Physical activity of university students with disabilities: accomplishment of recommendations and differences by age, sex, disability and weight stat…
2018
Abstract Objectives This article aims to study physical activity and the achievement of World Health Organization physical activity recommendations in university students with disabilities, and to examine differences by sex, age, disability characteristics and weight status. Study design Cross-sectional data from a wider research project conducted at the Spanish universities from Autumn 2016 to Autumn 2017 were analysed. Methods The International Physical Activity Questionnaire-Short Form was administered to 1103 Spanish university students with different disabilities. Nonparametric tests were performed to examine the differences in physical activity based on the interest variables. Results…
Bone mineral density and physical activity in 50–60-year-old women
1991
Abstract The bone mineral density (BMD) of the calcaneus was measured utilizing a single energy photon absorption method in 108 women, aged 50–60 years. The women who participated in vigorous exercise two or more times a week or whose total physical activity amounted to 4 h a week had significantly higher BMD values than those who exercised less than two times a week or did less than 4 h physical activity a week. The physically active women also showed higher values for leg extension force and maximal oxygen uptake. BMD and leg extension force were positively correlated, whereas correlations between BMD and body mass, and the width of the calcaneus were negative. When other life-style varia…
