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
2012
Naakka, Teppo Suorituskykyongelmien minimointi monimutkaisissa Java-pohjaisissa sovelluk-sissa Jyväskylä: Jyväskylän yliopisto, 2012, 39 s. Tietojärjestelmätiede, kandidaatintutkielma Ohjaaja(t): Hirvonen, Pertti Javan nouseminen teollisuuden standardiksi ohjelmistokehityskieleksi on joh-tanut siihen, että Java-pohjaisilla teknologioilla on tehty markkinoiden moni-mutkaisimmat sovellukset. Jotta monimutkaisia sovelluksia voidaan toteuttaa tehokkaasti, vaatii se erilaisten kehysjärjestelmien ja kirjastojen käyttöä. Tyypil-lisesti monimutkaisissa sovelluksissa on useita kirjastoja ja kehysjärjestelmiä, jotka monesti riippuvat toisistaan. Monimutkaiset sovellukset ja useat kirjastot ja kehysjä…
Samband mellan fysisk aktivitet och konsumtion av kaffe och energidrycker i årskurs 9
2016
Dahlberg, F. 2016. Samband mellan fysisk aktivitet och konsumtion av kaffe och energidrycker. Pro gradu-avhandling i idrottspedagogik. Institutionen för idrottsvetenskaper. Jyväskylä universitet. 66 sidor. Syftet med avhandlingen är att undersöka kaffe- och energidryckskonsumtion bland elever i årskurs 9. Jag intresserar mig speciellt för att undersöka om det finns samband mellan å ena sidan elevernas fysiska aktivitet och deras deltagande i föreningsidrott och å andra sidan kaffe- och energidryckskonsumtion. I den kvantitativa undersökningen har enkät används som datainsamlingsmetod. I undersökningen deltog 1850 elever i årskurs 9 i både svenska och finska skolor i regionen svenska Österbo…

Self-Regulation in High-Level Ice Hockey Players: An Application of the MuSt Theory
2021
The purpose of the study was to examine the validity of core action elements and feeling states in ice hockey players in the prediction of performance. A second aim of the study was to explore the effectiveness of a 30-day program targeting action and emotion regulation. Participants were male ice hockey players drawn from two teams competing at the highest level of the junior Finnish ice hockey league. They were assigned to a self-regulation (n = 24) and a control (n = 19) group. The self-regulation program focused on the recreation of optimal execution of core action elements and functional feeling states. Separate repeated measures MANOVAs indicated significant differences in ratings of …
Wax on, wax off, or whatever works for you : on the role of pre-competition emotions in elite karateka
2015
The purpose of the current study aimed to examine the performance related experiences of elite karate athletes prior to a major international competition. The secondary aim was to explore the relationship between athlete and coach performance ratings. Athletes selected emotional and non-emotional words to describe their experiences related to performance. Results indicated that best performance was characterized by high intensities of helpful emotion and non-emotion descriptors, while worst performance was characterized by high intensities of harmful descriptors. Moreover, intensities of emotions and non-emotions during actual good performance neared intensities recalled during best perform…
