Effects of nine months resistance training on cycling economy in elderly men and women
2016
The aging process, along with the lifestyle, is associated with loses in functional capacity and independence due to factors such as decreases in muscle mass, strength, and aerobic capacity, among others. Resistance training (RT) has been shown to induce strength and muscle size gains in the elderly. Improvements in maximal endurance capacity have been shown in some studies, while others have found no change. The purpose of the present study was to examine the effects of RT on the cycling economy in the elderly. A group of 47 older men and women (65-75 years) participated in the study. Subjects were assigned into one of two groups: 1) a training group performing 3 months of RT focusing on l…
Association between osteocalcin and cognitive performance in healthy older adults.
2016
INTRODUCTION: cognitive deterioration and reductions of bone health coincide with increasing age. We examine the relationship between bone composition and plasma markers of bone remodelling with measures of cognitive performance in healthy adults.METHODS: this cross-sectional study included 225 old (52% women, mean age: 74.4 ± 3.3 years) and 134 young (52% women, mean age: 23.4 ± 2.7 years) adult participants from the MyoAge project. Whole body bone mineral density was measured by dual-energy X-ray absorptiometry. Blood analyses included a panel of bone-related peptides (dickkopf-1, osteoprotegerin, osteocalcin (OC), osteopontin, sclerostin, parathyroid hormone and fibroblast growth factor …
Twin studies on the association of physical activity with cognitive and cerebral outcomes
2020
Regular physical activity (PA) offers positive effects on the human body. However, the effects of PA on cognition and in the brain are less clear. In this paper, we narratively review the relationship of PA with cognition and dementia, first from general perspective and then through genetically informed studies on the topic. Then we move on to imaging studies on exercise and brain anatomy first by presenting an overall picture of the topic and then discussing brain imaging studies addressing PA and brain structure in twins in more detailed way. Regarding PA and cognition or dementia, genetically informed studies are uncommon, even though the relationship between PA and cognitive ageing has …
Accumulation of disparity in physical activity in old age
2012
Background and aims: The level of physical activity often declines in old age, although many older people would like to be more active than what they are capable of. This leads to unmet physical activity need, the feeling that one’s level of physical activity is inadequate, which is a manifestation of disparity in physical activity in old age. The accumulation of risk factors, including mobility limitations, low socioeconomic status (SES) and lack of social support may increase disparity in physical activity. The aim of this study was to investigate how the accumulation of risk factors is associated with unmet physical activity need in older community-living people. Methods: The study was b…

The role of age and life course stage in digital consumption
2018
Digital technologies are an inherent part of consumer environments today. This dissertation investigates older adults’ usage of digital technologies by focusing on the role of age and life course stage in digital consumption in Finland. The dissertation applies theories of technology adoption and use, generations, and life course to examine older adults as digital consumers, the interrelationship between consumption and digital technologies and the effects of age and life course stage on digital consumption. The study utilises both quantitative and qualitative data from five (5) data sets. The results reveal that between the years 1999 and 2014, older adults reported more ecological and les…
Lifespan and skeletal muscle properties the effects of genetic background, physical activity and aging
2016
Obesity and metabolic disorders have become a notable world-wide epidemic. The pathogenesis of metabolic diseases, such as metabolic syndrome and type 2 diabetes, has begun to negatively affect life expectancy of current generations. Low aerobic capacity has shown to be a strong predictor of mortality both in rodents and humans. Exercise is known to increase an individual’s aerobic capacity; interestingly, recent studies have suggested that genetic background may play a significant role in the physical activity level of an individual. The purpose of this study was to investigate the role of genetic background and physical activity on skeletal muscle properties, metabolism and lifespan. The …

Seuruu- ja vertailututkimus sosioekonomisen aseman yhteydestä toimintakykyyn iäkkäillä henkilöillä
2006
The purpose of this follow-up study was, first, to examine the associations between socio-economic position and functional capacity over five and ten years among elderly people living in Jyväskylä and, second, to investigate the factors which may mediate these associations. In addition, the aim was to compare the above-mentioned associations among the Jyväskylä (Finland) elderly with elderly people in Göteborg (Sweden) and among older women in Britain and in Jyväskylä. The study is a part of the Evergreen, NORA, and BURDIS projects. The data were collected by interviews, questionnaires and examinations at the study centre. 1 409 persons aged 65 to 84 from Jyväskylä participated in the inter…
Iäkkäiden ihmisten ja eläkeikäisten vapaaehtoistyöntekijöiden kokemuksia kanssakäymisestä vapaaehtoistyössä
2022
Kotona asumista korostavan hoivapolitiikan seurauksena on paljon iäkkäitä henkilöitä, jotka eivät pääse ulos kodistaan ilman apua. Tutkimuksessa tarkastellaan huonokuntoisten iäkkäiden ihmisten ja eläkeikäisten vapaaehtoistyöntekijöiden kokemuksia keskinäisestä kanssakäymisestään vapaaehtoistyöhön perustuvalla toimintajaksolla. Vapaaehtoistyöntekijät auttoivat kodin ulkopuolisiin aktiviteetteihin yksin asuvia iäkkäitä ihmisiä, joilla oli liikkumiskyvyn ongelmia. Tutkimuksessa oli mukana viisi iäkkään ihmisen ja eläkeikäisen vapaaehtoistyöntekijän muodostamaa paria. Tutkimusaineisto koostui iäkkäiden (79–87-vuotiaiden) ihmisten ja vapaaehtoistyöntekijöiden (61–71-vuotiaiden) yksilöhaastattel…
