Change in physical activity and health-related quality of life in old age-A 10-year follow-up study.
2019
The aim of the study was to examine the association between change in leisure-time physical activity (LTPA) and change in health-related quality of life (HRQoL) and symptoms of depression during a 10-year follow-up. This prospective study included 1036 men and women (mean age at baseline = 61.2 years) from the Helsinki Birth Cohort Study. Leisure-time physical activity was measured with a questionnaire, HRQoL with SF36 and depression symptoms with Beck's depression inventory (BDI). The association between the change in LTPA and change in HRQoL and BDI were investigated with sex-stratified general linear models adjusted for age, smoking, educational attainment, comorbidity score, and baselin…
Cardiorespiratory and muscular fitness in young adult Finnish men between 2003 and 2015
2020
Introduction Physical fitness is strongly related to health and may offer valuable information about public health. We investigated trends in physical fitness, leisure-time physical activity (LTPA), and anthropometry of young healthy adult Finnish men in representative population-based samples between 2003 and 2015. Methods Three independent cross-sectional samples of 18- to 35-year-old Finnish men were assessed in 2003 (n = 889), 2008 (n = 803), and 2015 (n = 690). Cardiorespiratory (VO(2)max) and muscular fitness (1-minute sit-ups and push-ups), body mass, and height were measured. Self-reported LTPA was assessed. Results After adjusting for age, education, and smoking, cardiorespiratory …
Longitudinal physical activity trajectories from childhood to adulthood and their determinants: The Young Finns Study
2018
Determining lifelong physical activity (PA) trajectories and their determinants is essential to promote a physically active lifestyle throughout the life-course. We aimed to identify PA trajectories from childhood to midlife and their determinants in a longitudinal population-based cohort. This study is a part of the Cardiovascular Risk in Young Finns Study. From 1980, a population-based cohort (N = 3596; 1764 boys/1832 girls, age 3-18 years) has been followed up for 31 years. PA indices were formed based on self-reported data (between age 9-49 years) on frequency, duration, and intensity of leisure (during childhood) or high-intensity (at later age) PA and on sports club participation/comp…

Examining Controlling Styles of Significant Others and Their Implications for Motivation, Boredom and Burnout in Young Swimmers
2021
The aim of the study was to examine the controlling style in two contexts of social influence: the team (i.e., coach and teammates) and the family (i.e., father and mother), as well as the mediational role of motivation (autonomous, controlled, and amotivation) and its relationship with boredom and burnout in young swimmers. To this end, 267 swimmers (140 girls and 127 boys) between 12 and 18 years of age (M = 14.26; SD = 1.61) were assessed. The results showed that in the team context, coaches’ controlling style directly promoted controlled motivation and boredom in their swimmers, and indirectly influenced burnout through the mediating role of swimmers’ controlled motivation. Teammates’ c…
Parental and Peer Support Matters: A Broad Umbrella of the Role of Perceived Social Support in the Association between Children’s Perceived Motor Com…
2021
(1) Background: This study aimed to examine the role of social support in the relationship between perceived motor competence (MC) and physical activity (PA), according to the conceptual model of Motor Development. (2) Methods: Participants were 518 students (46.5% girls), 8–12 years old. By using a structural equation modeling approach, path analysis was used to test the actual-perceived MC relationship and the mediating influence of social support on the perceived MC–PA relationship. Analyses were done with age and sex as covariates. (3) Results: The results showed a good model fit (CFI = 0.98
Effect of Prolonged Military Field Training on Neuromuscular and Hormonal Responses and Shooting Performance in Warfighters
2018
Introduction: Previous studies have shown that military field training (MFT) has effects on warfighters’ hormonal responses, neuromuscular performance, and shooting accuracy. The aim of the present study was to investigate the changes in body composition, upper and lower body strength, serum hormone concentrations of testosterone (TES) and cortisol (COR), insulin-like growth factor-1 (IGF-1), and sex hormone binding globulin (SHBG) and shooting accuracy during prolonged MFT. Methods: Serum hormone concentrations, isometric strength of the upper and lower extremities, and shooting performance were measured four times during the study: before MFT (PRE), after 12 d (MID), at the end of MFT (PO…
Test–retest reliability and responsiveness of centre of pressure measurements in patients with hip osteoarthritis
2015
International audience; Objective: The aim of this study was to determine a set of measures for the evaluation of balance in patients suffering from hip osteoarthritis (OA) that were both reliable and responsive to change.Design: Three groups of subjects; Healthy, hip OA patients without surgery, and hip OA with surgery (pre and post-surgery) were included in this study. Subjects had to perform balance tests in two positions: standard and narrowed stance. CoP-based measures test-retest reliability was assessed in hip OA without surgery group, responsiveness were assessed between all groups and between pre and postsurgery.Results: Intraclass Correlation Coefficient (ICC) values from hip OA w…
Dynamic thoracohumeral kinematics are dependent upon the etiology of the shoulder injury.
2017
[EN] Obtaining kinematic patterns that depend on the shoulder injury may be important when planning rehabilitation. The main goal of this study is to explore whether the kinematic patterns of continuous and repetitive shoulder elevation motions are different according to the type of shoulder injury in question, specifically tendinopathy or rotator cuff tear, and to analyze the influence of the load handled during its assessment. For this purpose, 19 individuals with tendinopathy and 9 with rotator cuff tear performed a repetitive scaption movement that was assessed with stereophotogrammetry. Furthermore, static range of motion (ROM) and isometric strength were evaluated with a goniometer an…
Test-retest reliability of 3D kinematic gait variables in hip osteoarthritis patients
2011
Import JabRef | WosArea Orthopedics; Rheumatology; International audience; Objectives: (1) to investigate the test-retest reliability of 3D gait analysis (3DGA) in hip Osteoarthritis (OA) patients; (2) to find the minimum number of gait trials needed to overcome intrinsic variability; (3) to check the accuracy of angles measured by the 3D system. Design: 23 Patients suffering from hip OA with no other major disease were recruited. We evaluated the reliability of spatio-temporal variables and body angles (lower-limb joints, trunk and pelvis angles) during two sessions of 3DGA using intra-class correlation coefficients (ICC). The minimum number of trials needed to overcome intrinsic variabili…
