The association of socio-economic factors with physical and mental capacity in elderly men and women
2000
The association of socio-economic factors with functional capacity has received less research attention than their association with diseases and mortality. However, functional capacity is an important measure of health and independence in the elderly. This study explores the associations of socio-economic factors with physical and mental capacity as measured in laboratory tests and on the basis of self-report. The data were drawn from the Evergreen project, comprising all persons aged 75 (N=388) and 80 (N=291) in Jyväskylä, central Finland. Women with a higher level of education showed better functional capacity on all indicators, among men higher education was only associated with better v…
Estimation of aerobic fitness among young men without exercise test
2015
Summary Study aim: to develop and estimate the validity of non-exercise methods to predict VO2max among young male conscripts entering military service in order to divide them into the different physical training groups. Material and methods: fifty males (age 19.7 ± 0.3 years) reported their physical activity before military service by IPAQ and SIVAQ questionnaires. Furthermore, Jackson’s non-exercise method was used to estimate VO2max. Body mass and height were measured, body mass index calculated and VO2max measured directly in a maximal treadmill test. Subjects were randomly divided into two groups. The results of the Group 1 (N = 25) were used to develop a regression equation to estimat…
A path analysis model of self-rated health among older people.
1999
The aim of this study was to examine the structure of self-rated health among 75-year-old men and women. The study was part of the Evergreen project, comprising all the 75-year-old residents (N = 382) of Jyväskylä, in central Finland, in 1989. The data were collected by interviews, questionnaires and laboratory examinations, focusing on different domains of health and functional capacity. Of the target group, 91.6% (119 men and 231 women) participated in the interview, and 77.2% (104 men and 191 women) took part in the clinical and laboratory examinations. Path analysis models (LISREL 8) were used to examine the structure of self-rated health. About half the participants self-rated their he…
Aerobic fitness, but not physical activity, is associated with grey matter volume in adolescents.
2019
Higher levels of aerobic fitness and physical activity are linked to beneficial effects on brain health, especially in older adults. The generalizability of these earlier results to young individuals is not straightforward, because physiological responses (such as cardiovascular responses) to exercise may depend on age. Earlier studies have mostly focused on the effects of either physical activity or aerobic fitness on the brain. Yet, while physical activity indicates the amount of activity, aerobic fitness is an adaptive state or attribute that an individual has or achieves. Here, by measuring both physical activity and aerobic fitness in the same study, we aimed to differentiate the assoc…
Heritability of Lung Function: A Twin Study Among Never-Smoking Elderly Women
2011
Most studies on lung function heritability have been conducted in smokers and non-smokers using cross-sectional study design. Smoking patterns may, however, confound the contribution of genetic factors. We investigated heritability of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio longitudinally, excluding the effects of smoking. A sample of never smoking female twins (n = 374), aged 63–76 at baseline, answered health questionnaires and attended spirometry in years 2000 and 2003. Bivariate structural equation modeling, restricted to adequate spirometry performances (baseline n = 339, follow-up n = 252), was used to estimate genetic and environ…
Reversal of age-associated frailty by controlled physical exercise: The pre-clinical and clinical evidences.
2019
Demographic aging is one of the most serious challenges facing our society. Although we live longer, we do not live better because it is considered that approximately 16–20% of our life is spent in late-life morbidity. Older people have the greatest risk of developing frailty increasing the risk of presenting various adverse health events such as low quality of life, disability, hospitalization and even death. Frail men and women over 65 years old have lower muscle quality and muscle mass and higher percentage of body fat than non-frail people of the same age. In this review we will address the main physiological changes in the muscular and nervous system associated to aging. More specifica…
Physical performance in relation to menopause status and physical activity
2018
Objective: The aim of this study was to examine differences in physical performance (muscle power, muscle strength, aerobic capacity, and walking speed) across menopausal stages and potential of leisure physical activity (PA) to modify the impact of menopause on physical performance. Methods: In this cross-sectional study, women aged 47 to 55 were randomly selected from the Finnish National Registry and categorized as premenopausal (n ¼ 233), perimenopausal (n ¼ 381), or postmenopausal (n ¼ 299) based on serum concentrations of follicle-stimulating hormone and bleeding diary. Physical performance was measured by knee extension force, handgrip force, vertical jumping height, maximal walking …
In-situ transformation of iron-bearing minerals in marshland-derived paddy subsoil
2016
Transformations of Fe-bearing minerals under alternating redox conditions are not fully understood. In-situ approaches under field conditions have rarely been used. We exposed mesh bags containing ferrihydrite, goethite or nontronite to changing redox conditions in subsoil that had been under paddy management for 100, 700 and 2000 years. After 12 months, the minerals were retrieved and analysed for organic carbon and by X-ray diffraction; in addition, nontronite was analysed for cation exchange capacity and by Mossbauer spectroscopy at 278 and 4.2 K. Field exposure of the test minerals was complemented by measurements of soil redox potential and analyses of soil water. Minerals accumulated …
The Spanish Case: The Housing Market Bubble and External Disequilibria
2013
The chapter recalls the major issues at stake in the Spanish economy since 1996, a time when financial markets started to discount the Spanish entry into the Eurozone. We start with a brief analysis of the most recent economic developments, and the current macroeconomic imbalances. As of 2007, the Spanish economy underwent its worst period in recent history, since the Stabilisation Plan was implemented in 1959. When 2008 came, however, what was most worrying was the sense of disarray that the Government projected: it simply took measures against the global financial crisis, as though this were the major, and indeed, the only crisis to cope with. Nevertheless, what affected the Spanish econo…
Control cuantitativo de la calidad en una empresa del sector servicios = Quantitative quality control in a company of the service industry
2013
<p>En el presente trabajo se aplican herramientas de Control Estadístico de Calidad, habitualmente utilizadas en procesos productivos, a una empresa dedicada a la auditoría y que por tanto pertenece al sector servicios. La elección de las herramientas utilizadas (gráficos de control, indicadores de capacidad, función de pérdida de Taguchi…) obedece a la necesidad de controlar si se cumple el objetivo de la empresa de realizar la auditoría a la empresa cliente 7 días antes de la fecha teórica, lo que conlleva una disminución de costes. También se cuantifica la pérdida que produce el incumplimiento de dicho objetivo y se proponen medidas correctoras que disminuyen la variabilidad del pr…
