Effect of bicycle ergometer test on intraocular pressure in elderly athletes and controls.
2009
To evaluate the effect of intensive physical exercise on intraocular pressure (IOP) in 66- to 85-year-old subjects IOP was measured before and after a maximal bicycle ergometer test. The non-glaucomatous subjects comprised 85 males and 36 female athletes and 16 male and 22 female controls of corresponding age drawn from a population register. IOP was measured using a non-contact tonometer. The results indicated a decrease (> or = 2 mmHg) in 34% of the subjects, no change in 57% and an increase in 9%. The decrease was more pronounced in subjects with higher pre-test values. In all four subjects with a pre-test value above 22 mmHg a reduction from 4 to 11 mmHg was observed. The change in IOP …
Susceptibility of mouse skeletal muscles to exercise injuries.
1983
The susceptibility to exercise-induced myopathy was studied by histological and biochemical methods in various skeletal muscles of mice 3-4 days after a single bout of prolonged running. The degree of exercise injuries varied greatly in different muscles. Soleus and the red deep parts of quadriceps femoris were the most severely affected muscles. Extensive or scattered necrosis of muscle fibers was associated with focal inflammation and a five- to nine-fold increase in the activity of beta-glucuronidase in these muscles. Slight necrotic changes and a two- to three-fold increase in the activity of beta-glucuronidase were observed in tibialis anterior, plantaris, and the red deep parts of gas…
Promoting Physical Activity Habits after Completing Secondary School: Does the Age Matter?
2022
Physical inactivity is one of the most important problems in our society, especially during adolescence. During this stage of schooling, students practice physical activity in physical education classes, but after they finish school, many of them stop practicing it. This research aims to determine which variables predict the intention to practice physical activity after finishing secondary school and to discover the effect that age during adolescence has on these predictive variables. A questionnaire was administered to a sample of secondary school students. The results show that physical exercise identity influences the three antecedents of this theory, while the attitude towards the behav…
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…
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 …
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…
Older adults’ activity destinations before and during COVID-19 restrictions: From a variety of activities to mostly physical exercise close to home
2021
The aim was to study various types of older adult's activity destinations (counts, frequency of visitation, and distance from home) in the pre-COVID-19 era, and to study prospectively how COVID-19-related regulations limiting mobility affected these. Using a map-based questionnaire, 75-85-year-old participants reported activity destinations, that is, any destinations for physical exercise, destinations facilitating one's outdoor mobility, and destinations for other activities, which they had visited several times during the past month. At baseline, a variety of activity destinations was reported, but during COVID-19, destinations reported markedly declined in number, they were reported pred…
Randomized comparison between clinical evaluation plus N-terminal pro–B-type natriuretic peptide versus exercise testing for decision making in acute…
2009
Background Exercise testing constitutes the usual tool for decision making in chest pain units. This policy implies logistical constrains. Our aim was to evaluate a new strategy, combining a clinical risk score and N-terminal pro–B-type natriuretic peptide (NT-proBNP), in patients presenting to the emergency department with chest pain, without ischemic electrocardiogram changes or troponin elevation. Methods A total of 320 patients were randomized to either usual management, involving exercise testing, or a new strategy combining a clinical risk score and NT-proBNP without exercise testing. In the usual management, discharge decision was guided by the result of exercise test. In the new str…
