Adolescent Motivation Toward Physical Exercise: The Role of Sex, Age, Enjoyment, and Anxiety
2020
Physical exercise declines during adolescence due to several factors, such as lack of intrinsic motivation or enjoyment, high physical exercise anxiety, and so on. The objectives of this study were to validate the psychometric structure of the Behavioral Regulation in Exercise Questionnaire-2 to confirm the existence of five levels of motivation toward physical exercise in adolescent population, as well as to analyze the differences in motivation according to sex and age, and the role of age and sex in the relationship between motivation and enjoyment. To do so, 666 students between 10 and 16 years old completed the Behavioral Regulation in Exercise Questionnaire-2 and questionnaires relat…
Changes in Intensity of Physical Exercise as Predictors of Depressive Symptoms among Older Adults: An Eight-Year Follow-Up
2000
Abstract Background. Epidemiological research suggests that regular physical activity may be associated with reduced depressive symptoms. The present study examines the predictive value of physical exercise in relation to depressive symptoms among samples of adults aged 65+ during an 8-year period. Methods. The subjects (N = 663) who participated both at the baseline (1988) and the follow-up (1996) interviews were selected for the analyses. The dependent variable depressive symptoms was assessed by the Finnish modified version of Beck's 13-item depression scale. The independent variable was the intensity of physical exercise. Results. The intensity of physical exercise decreased among the o…
Physical activity levels in adults and elderly from triaxial and uniaxial accelerometry. The Tromsø study
2019
Introduction - Surveillance of physical activity at the population level increases the knowledge on levels and trends of physical activity, which may support public health initiatives to promote physical activity. Physical activity assessed by accelerometry is challenged by varying data processing procedures, which influences the outcome. We aimed to describe the levels and prevalence estimates of physical activity, and to examine how triaxial and uniaxial accelerometry data influences these estimates, in a large population-based cohort of Norwegian adults. Methods - This cross-sectional study included 5918 women and men aged 40–84 years who participated in the seventh wave of the Tromsø St…
Reduction of mdx mouse muscle degeneration by low-intensity endurance exercise: a proteomic analysis in quadriceps muscle of exercised versus sedenta…
2015
By proteomic analysis we found an up-regulation of four carbonic anhydrase-3 (CA3) isoforms and a down-regulation of superoxide dismutase [Cu-Zn] (SODC) in quadriceps of sedentary X-linked muscular dystrophy (mdx) mice as compared with wild–type (WT) mice and the levels were significantly restored to WT values following low-intensity endurance exercise.
Delayed Anaerobic Threshold in Heart Failure Patients With Atrial Fibrillation
2016
PURPOSE To assess whether atrial fibrillation (AF) in heart failure (HF) affects oxygen uptake at anaerobic threshold ((Equation is included in full-text article.)O2 AT) and heart rate (HR) kinetics. METHODS A total of 15 patients with HF and AF and 18 with HF and sinus rhythm (SR) performed a maximal incremental and 2 constant workload cycle ergometer cardiopulmonary exercise tests (below and above AT, at 25% and 75% of maximal workload, respectively). At constant workload tests, kinetics of (Equation is included in full-text article.)O2 and HR were assessed by calculating time constant (τ). RESULTS HF patients with AF showed a similar peak (Equation is included in full-text article.)O2 to…
Modulation of spinal excitability by a sub-threshold stimulation of M1 area during muscle lengthening
2013
Abstract It is well known that the H-reflex amplitude decreases during passive muscle lengthening in comparison with passive shortening. However, this decrease in spinal synaptic efficacy observed during passive lengthening seems to be lesser during eccentric voluntary contraction. The aim of the present study was to examine whether spinal excitability during lengthening condition could be modulated by magnetic brain stimulation. H reflexes of the triceps surae muscles were elicited on 10 young healthy subjects, and conditioned by a sub-threshold transcranial magnetic stimulation (TMS). The conditioning stimulation was applied over the M1 area of triceps surae muscles at an intensity below …
Design of a randomized controlled trial of physical training and cancer ( Phys-Can) the impact of exercise intensity on cancer related fatigue, quali…
2017
Background: Cancer-related fatigue is a common problem in persons with cancer, influencing health-related quality of life and causing a considerable challenge to society. Current evidence supports the beneficial effects of physical exercise in reducing fatigue, but the results across studies are not consistent, especially in terms of exercise intensity. It is also unclear whether use of behaviour change techniques can further increase exercise adherence and maintain physical activity behaviour. This study will investigate whether exercise intensity affects fatigue and health related quality of life in persons undergoing adjuvant cancer treatment. In addition, to examine effects of exercise …
Inspiratory Muscle Training and Functional Electrical Stimulation for Treatment of Heart Failure With Preserved Ejection Fraction: The TRAINING-HF Tr…
2019
Introduction and objectives: Despite the prevalence of heart failure with preserved ejection fraction (HFpEF), there is currently no evidence-based effective therapy for this disease. This study sought to evaluate whether inspiratory muscle training (IMT), functional electrical stimulation (FES), or a combination of both (IMT + FES) improves 12- and 24-week exercise capacity as well as left ventricular diastolic function, biomarker profile, and quality of life in HFpEF. Methods: A total of 61 stable symptomatic patients (New York Heart Association II-III) with HFpEF were randomized (1:1:1:1) to receive a 12-week program of IMT, FES, or IMT + FES vs usual care. The primary endpoint of the st…
Health situation and related social conditions among 66-year-old Finnish men.
1976
Health situation and related social conditions among 66-year-old Finnish men. Heikkinen, E., Käyhty-Seppänen, B. and Pohjolainen, P. (Dept. of Public Health, University of jyväskylä, Finland). The aims of the study were to reveal the extent of physical activity, nutritional habits, smoking and alcohol consumption and the relation of these to previous occupation among recently retired men. The number of men belonging to various health risk groups was estimated on the basis of the results. About 10% had inadequate nutritional habits as judged from their food expenses and number of daily hot meals and about 20% practised physical exercise in the way which is considered necessary for the impro…
Mortality Risk Among Older People Who Did Versus Did Not Sustain a Fracture: Baseline Prefracture Strength and Gait Speed as Predictors in a 15-Year …
2019
Abstract Background Physiological reserve, as indicated by muscle strength and gait speed, may be especially determinant of survival in people who are exposed to a health stressor. We studied whether the association between strength/speed and mortality risk would be stronger in the time period after a fracture compared to other time periods. Methods Participants were population-based sample of 157 men and 325 women aged 75 and 80 years at baseline. Maximal 10-m gait speed and maximal isometric grip and knee extension strength were tested at the baseline before the fracture. Subsequent fracture incidence and mortality were followed up for 15 years. Cox regression analysis was used to estimat…
