A Polygenic Risk Score for Hand Grip Strength Predicts Muscle Strength and Proximal and Distal Functional Outcomes among Older Women

2022

Purpose Hand grip strength (HGS) is a widely used indicator of overall muscle strength and general health. We computed a polygenic risk score (PRS) for HGS, and examined, whether it predicted muscle strength, functional capacity and disability outcomes. Methods Genome-wide association study summary statistics for HGS from the Pan-UK Biobank was utilized. PRSs were calculated in the Finnish Twin Study on Aging (N = 429 women, 63–76 years). Strength tests included HGS, isometric knee extension, and ankle plantar flexion strength. Functional capacity was examined with the Timed Up and Go, six-minute and 10-meter walk tests, and dual-task tests. Disabilities in the basic (ADL) and instrumental …

Load-dependent alpha suppression is related to working memory capacity for numbers

2022

Alpha suppression is proposed to reflect a surge in cortical excitability to enhance stimulus processing in working memory. The attenuated state of alpha might reflect the prioritisation of behaviourally relevant information, making it a proxy for working memory functioning. Despite the growing interest in utilising the advancement of brain-based measures to evaluate individuals’ cognitive processes, there was a lack of consistent evidence on the relationship between alpha suppression and working memory performance. To investigate whether interindividual differences in alpha suppression might be related to variability in working memory capacity, we recorded participants’ electroencephalogra…

Satelliittijärjestelmän linkkibudjettianalyysi

2013

Tutkielmassa selvitetään kirjallisuuskatsauksen avulla DVB-S ja DVB-RCS standardien mukaisten interaktiivisten satelliittijärjestelmien linkkibudjettia.

1H NMR Urinary Metabolomic Analysis in Older Adults after Hip Fracture Surgery May Provide Valuable Information for Patient Profiling : A Preliminary…

2022

In these times of precision and personalized medicine, profiling patients to identify their needs is crucial to providing the best and most cost-effective treatment. In this study, we used urine metabolomics to explore the characterization of older adults with hip fractures and to explore the forecasting of patient outcomes. Overnight urine specimens were collected from 33 patients (mean age 80 ± 8 years) after hip fracture surgery during their stay at a rehabilitation hospital. The specimens were analyzed with 1H NMR spectroscopy. We performed a metabolomics study regarding assessments of frailty status, Functional Independence Measure (FIM), and Short Physical Performance Battery (SPPB). …

Changes in Body Composition, Energy Metabolites and Electrolytes During Winter Survival Training in Male Soldiers

2022

The aim of this study was to examine changes in body composition, energy metabolites and electrolytes during a 10-day winter survival training period. Two groups of male soldiers were examined: the REC group (n = 26; age 19.7 ± 1.2 years; BMI 23.9 ± 2.7) had recovery period between days 6 and 8 in the survival training, whereas the EXC group (n = 42; age 19.6 ± 0.8 years; BMI 23.1 ± 2.8) did not. The following data were collected: body composition (bioimpedance), energy balance (food diaries, heart rate variability measurements), and biomarkers (blood samples). In survival training, estimated energy balance was highly negative: −4,323 ± 1,515 kcal/d (EXC) and −4,635 ± 1,742 kcal/d (REC). Be…

Physiological and physical performance changes during a 20-day winter military training course and its subsequent 10-day recovery period

2023

The present study investigated physiological, mental and physical performance changes during a 20-day winter military training course and the following 10-day recovery period. Fifty-eight (age 19 ± 1 years, height 182 ± 6 cm, body mass 78.5 ± 7.2 kg) male soldiers volunteered. Body composition, serum biomarker levels and performance tests were measured four times during the study. In addition, questionnaires were collected daily for subjective stress and rate of perceived exertion. The course induced significant declines in body (−3.9%, p < 0.05) and fat mass (−31.6%, p < 0.05) as well as in all assessed physical performance variables (−9.2 - −20.2%, p < 0.05), testosterone (−73.7%, p < 0.0…

Coaches’ Perceptions of Athletes’ Psychobiosocial States : The Case of Three Tennis Coach-Athlete Dyads

2018

Considering the limited attention paid to interpersonal aspects of emotions, this study explored coaches’ perceptions of athletes’ performance-related states and how they used this information for its regulation. Using a case study approach, three coach-athlete dyads from competitive tennis took part in one-on-one semi-structured interviews. Individualized profiling of psychobiosocial states was used to assess athletes’ states in most and least successful performances and as a way of data triangulation. Findings indicated that the coaches paid attention to bodily, motor-behavioural, and operational components of a performance state, and used this information to appropriately adapt their res…

Performance-related fear experiences, coping and perceived functional impact on highly skilled athletes

2013

ABSTRACT Melina Puolamäki, 2013. Performance-related fear experiences, coping and perceived functional impact on highly skilled athletes. Master’s Thesis in Sport and Exercise Psychology. Department of Sport Science, University of Jyväskylä. 68p. Three types of experiences are distinguished in sport: emotional states (state-like), emotion patterns (trait-like), and meta-experiences or attitudes towards one’s experiences (Hanin, 2004). Most emotion research has traditionally focused on the study of anxiety and its impact on athletic performance. Although unpleasant emotions have been assumed harmful for performance, previous research on anxiety (Hanin, 2000) and anger (Ruiz & Hanin, 2011) ha…

Suorituskykyongelmien minimointi monimutkaisissa Java-pohjaisissa sovelluksissa
