Why English? : Finnish streamers' views on their language choice

2017

Videopelien reaaliaikainen jakaminen on yleistynyt viime vuosina valtavasti ja suoratoistopalvelu Twitch on kerännyt miljoonia pelisessioitaan jakavia kaikkialta maailmasta ja streamaamisesta onkin kehittynyt miljoonabisnes. Tutkielmani perehtyy suomalaisten streamaajien kielivalintoihin, kun he ovat päättäneet käyttää streamiensa kielenä englantia suomen sijasta. Tutkielmani tarkoitus oli selvittää mikä motivoi suomalaiset pelaajat streamaamaan juuri englanniksi ja millaisia näkemyksiä heillä on omaa kielivalintaansa kohtaan ja mikä heidän suhteensa englannin kieleen on. Tutkimukseni koostui kolmen suomalaisen streamaajan haastatteluista. Haastatteluissa pyrin ymmärtämään osallistujien kie…

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 …

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…

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 …

Effects of hormonal contraceptives on physical performance and body composition

2016

The purpose of the present study was to examine the effects of hormonal contraceptive use on neuromuscular, cardiorespiratory and body composition adaptations following combined strength and endurance training period. Methods. Nineteen recreationally active women; 11 who had at least one year of hormonal contraceptive use (age 294 yr; BMI 212 kg/m2; VO2max 444 ml/kg/min) and 8 who had never used hormonal contraceptives (age 315 yr; BMI 222 kg/m2; VO2max 414 ml/kg/min) participated in the present study of combined strength and endurance training for 10 weeks. Training consisted of two maximal and explosive strength training sessions, and two high-intensity interval training sessions pe…

Mental Skills of an Athlete as a Resource of Professional Longevity in Sport

2021

The aim of the study was to assess associations between dimensions of mental skills, psychological readiness and predictors of career longevity among current athletes. Mental skills dimensions were measured with the Ottawa Mental Skills Assessment Tool (OMSAT). The psychological predictors of athletic career longevity were measured with the Athletic Coping Skills Scale-28 (the ACSI-28) producing scores for seven coping skills and with the Competitive State Anxiety Inventory-2 (CSAI-2) which produced scores for confidence in competition. Overall, 253 current athletes (average age 22 years) of various competitive levels (classified to 5 groups according to the national sport classification sy…

Effects of Task-Specific and Strength Training on Simulated Military Task Performance in Soldiers.

2020

A soldier’s occupational physical task requirements are diverse and varied. However, the type of physical training that most effectively improves soldiers’ occupational task requirements has not been studied previously. The purpose of this study was to determine the important strength characteristics for soldiers during a repeated simulated military task course, and the type of training that may be effective to improve these abilities during a specialized military training period. Forty-two (n = 42) soldiers participated in the study. They were divided into three training groups; a soldier task-specific training group (TSG, n = 17), a strength training group (STG, n = 15), and a control gro…
