Effect of 12-month supervised, home-based physical exercise on functioning among persons with signs of frailty : Randomized Controlled Trial
2021
Objectives To investigate the effects of a 12-month home-based exercise program on functioning and falls among persons with signs of frailty. Design A randomized controlled trial with a 1:1 allocation Setting Home-based Participants Home-dwelling persons aged ≥65 years meeting at least one frailty phenotype criteria (n=300). Intervention 12-month, individually tailored, progressive and physiotherapist-supervised, physical exercise twice a week (n=150) vs. usual care (n=149). Main outcome Measures Functional Independence Measure (FIM), Short Physical Performance Battery (SPPB), handgrip strength, instrumental activities of daily living (IADL), and self-reported falls and physical activity (o…
Effects of aging and training on sprint performance, muscle structure and contractile function in athletes
2009
Cross-sectional studies were conducted to examine sprint running, anaerobic energy production and muscle properties in male sprinters aged 17-88 years. In addition, a 20-week training intervention was carried out to determine whether older runners can further improve their neuromuscular and performance characteristics by a greater emphasis on strength training. With age, sprint performance declined gradually (5-6%/decade). The slowing of maximum speed was characterized by a reduction in stride length and an increase in contact time along with lower ground reaction forces (GRF) and smaller leg and vertical stiffness during the contact phase. Stride frequency showed small decline while swing …
Outdoor Mobility and Use of Adaptive or Maladaptive Walking Modifications among Older People
2020
Background. In old age, decline in functioning may cause changes in walking ability. Our aim was to study whether older people who report adaptive, maladaptive or no walking modifications differ in outdoor mobility. Methods. Community-dwelling people aged 75–90 years (N=848) were interviewed at baseline, of whom 761 participated in the 2-year follow-up. Walking modifications were assessed by asking the participants whether they had modified their way of walking 2 kilometers due to their health. Based on the responses, three categories were formed: no walking modifications (reference), adaptive (e.g., walking more slowly, using an aid) and maladaptive walking modifications (reduced frequency…

THE RELATIONSHIP BETWEEN WOMEN´S ARTISTIC GYMNASTICS TECHNICAL SKILL, PHYSICAL PERFORMANCE TEST RESULTS AND SUCCESS IN COMPETITIONS IN FINLAND
2019
The aim of this study was to find out the potential of the Minoritest to identify the most likely talented gymnasts to join the national team pre-training group in Finland. The study examined the relationships between gymnasts´ (N=215, age 10–13) Minoritest results (2006–2010) and success in competitions after the Minoritests until the end of 2016. The competition results were also compared between the gymnasts who had participated in the test and a random number (N=180) of gymnasts who had not. According to this study, the majority (92%) of the best gymnasts in competitions had participated in the Minoritest. 39% of the best in competitions were among the top 10 in the Minoritest. The test…
An Integrated Approach to Skeletal Muscle Health in Aging
2023
A decline in muscle mass and function represents one of the most problematic changes associated with aging, and has dramatic effects on autonomy and quality of life. Several factors contribute to the inexorable process of sarcopenia, such as mitochondrial and autophagy dysfunction, and the lack of regeneration capacity of satellite cells. The physiologic decline in muscle mass and in motoneuron functionality associated with aging is exacerbated by the sedentary lifestyle that accompanies elderly people. Regular physical activity is beneficial to most people, but the elderly need well-designed and carefully administered training programs that improve muscle mass and, consequently, both funct…

Engelska – resurs eller hot mot svenska språket på finska högstadiet? : lärarnas synpunkter på engelskans roll i svenskundervisning
2016
Tämän tutkielman tarkoitus on selvittää ruotsinopettajien mielipiteitä englannin kielen vaikutuksesta ja asemasta yläkoulun ruotsinopetuksessa. Tutkielmassa keskitytään erityisesti siihen voiko ruotsinopettajien mielestä englantia hyödyntää myös ruotsin opettamisessa ja jos voi, niin miten. Lisäksi tutkielmassa selvitetään kokevatko ruotsinopettajat englannin resurssina vai uhkana ruotsin kielelle. Tutkielma on toteutettu kyselytutkimuksena keväällä 2015 ja siihen osallistui 30 ruotsinopettajaa. Sähköinen kyselylomake sisälsi yhdeksän kysymystä, jotka olivat sekä avoimia kysymyksiä että monivalintoja. Materiaali on analysoitu pääasiassa kvantitatiivisin menetelmin, sillä tulokset esitetään …
