Effects of military basic training on VO2max, body composition, muscle strength and neural responses in conscripts of different aerobic condition
2019
Summary Study aim: The purpose of this study was to evaluate neuromuscular adaptations in conscripts with different fitness levels (VO2max) during 8 weeks of military basic training (BT). Material and methods: Twenty-four male conscripts (18–21 years) were divided into two groups (Good Fitness [GF] and Low fitness [LF]) based on their VO2max at the beginning of BT. Body mass (BM), fat free mass (FFM) and Fat% were measured after 2, 4, and 7 weeks of training. VO2max, maximal isometric leg press force (MVC), H-reflex (Hmax/Mmax) at rest and V-wave (V/Mmax) during maximal isometric plantarflexion were measured from the soleus muscle at the beginning, after 5, and after 8 weeks of training.

Psychosis, Need Adapted treatment, and psychiatrists' agency
2013
Background: In the Need-Adapted approach (NAA) therapy meetings are a deliberate effort to bring all meaningful parties and views to a common discussion prior to decisions; this constitutes a challenge for psychiatrists’ agency. Aims: To describe how psychiatrists see their agency in NAA. Methods: Using videos of co-research interviews, stimulated-recall interviews of 10 interviewees were conducted and transcribed verbatim. The material was analyzed via an adapted dialogical-narrative analytical method. Results: Institutional forces were experienced as having an enormous impact on psychiatrists’ agency, especially in the inpatient setting, reducing professional creativity. In the outpatient…
Associations of physical activity, fitness, and body composition with heart rate variability–based indicators of stress and recovery on workdays: a c…
2014
Background. The purpose of this study was to investigate how physical activity (PA), cardiorespiratory fitness (CRF), and body composition are associated with heart rate variability (HRV)-based indicators of stress and recovery on workdays. Additionally, we evaluated the association of objectively measured stress with self-reported burnout symptoms. Methods. Participants of this cross-sectional study were 81 healthy males (age range 26–40 y). Stress and recovery on workdays were measured objectively based on HRV recordings. CRF and anthropometry were assessed in laboratory conditions. The level of PA was based on a detailed PA interview (MET index [MET-h/d]) and self-reported activity class…
Effects of Combined Strength and Endurance Training on Body Composition, Physical Fitness, and Serum Hormones During a 6-Month Crisis Management Oper…

Pihlainen, K, Kyröläinen, H, Santtila, M, Ojanen, T, Raitanen, J, and Häkkinen, K. Effects of combined strength and endurance training on body composition, physical fitness, and serum hormones during a 6-month crisis management operation. J Strength Cond Res XX(X): 000-000, 2020-Very few studies have examined the impact of training interventions on soldier readiness during an international military operation. Therefore, the present study investigated the effects of combined strength and endurance training on body composition, physical performance, and hormonal status during a 6-month international military deployment consisting of typical peacekeeping tasks, e.g., patrolling, observation, a…
Hormonal Contraceptive Use Does Not Affect Strength, Endurance, or Body Composition Adaptations to Combined Strength and Endurance Training in Women
2021
Myllyaho, MM, Ihalainen, JK, Hackney, AC, Valtonen, M, Nummela, A, Vaara, E, Häkkinen, K, Kyröläinen, H, and Taipale, RS. Hormonal contraceptive use does not affect strength, endurance, or body composition adaptations to combined strength and endurance training in women. J Strength Cond Res 35(2): 449-457, 2021-This study examined the effects of a 10-week period of high-intensity combined strength and endurance training on strength, endurance, body composition, and serum hormone concentrations in physically active women using hormonal contraceptives (HCs, n = 9) compared with those who had never used hormonal contraceptives (NHCs, n = 9). Training consisted of 2 strength training sessions a…
Hormone Replacement Therapy Associated White Blood Cell DNA Methylation and Gene Expression are Associated With Within-Pair Differences of Body Adipo…
2015
The loss of estrogen during menopause causes changes in the female body, with wide-ranging effects on health. Estrogen-containing hormone replacement therapy (HRT) leads to a relief of typical menopausal symptoms, benefits bone and muscle health, and is associated with tissue-specific gene expression profiles. As gene expression is controlled by epigenetic factors (including DNA methylation), many of which are environmentally sensitive, it is plausible that at least part of the HRT-associated gene expression is due to changes in DNA methylation profile. We investigated genome-wide DNA methylation and gene expression patterns of white blood cells (WBCs) and their associations with body compo…
The Effect of 16-Minute Thermal Stress and 2-Minute Cold Water Immersion on the Physiological Parameters of Young Sedentary Men
2020
This study aimed to determine the effect of 16 minutes of thermal stress followed by 2 minutes of cold water immersion on the physiological parameters of fifty-five sedentary men (mean age 20.15±1.30 years), who were exposed to 16 minutes of sauna (temperature: 90-91℃; relative humidity: 14-16%) followed by 2 minutes of cold water immersion (12℃). The participants' somatic characteristics were determined before entering the sauna, and their body mass and blood pressure were measured before and after sauna treatment. Physiological parameters were monitored during the 16-minute sauna session and the 2-minute cold water immersion (CRIO) or shower. The subjects perspired 0.21-0.27 litres during…
Työterveyshuollon menetelmät liikuntaan motivoinnissa : työkaluina askelmittari, kehonkoostumusmittaus sekä kuntoindeksin mittaus
2016
Gustafsson – Tuhkunen, C. 2016. Työterveyshuollon menetelmät liikuntaan motivoinnissa – työkaluina askelmittari, kehonkoostumusmittaus sekä kuntoindeksin mittaus. Terveystieteiden laitos, Jyväskylän yliopisto, terveyskasvatuksen pro gradu -tutkielma, 55 s., 4 liitettä. Liikkumattomuuden haitat ovat maailmanlaajuinen kansanterveydellinen ongelma. Liikunnan terveyshyödyistä on esitetty runsaasti tutkimustietoa. Kotimaisten tutkimusten mukaan vähintään joka viides suomalainen ei liiku ollenkaan. Tämän tutkimuksen tarkoituksena oli selvittää työikäisten liikkumiseen liittyviä tekijöitä sekä työterveyshuoltoon järjestetyn intervention avulla sitä, voidaanko työikäisten liikkumista motivoida yksi…
Veren rasvojen ja mielialan muutokset varusmiespalveluksen peruskoulutuskaudella - sekä niiden yhteys kehon koostumukseen, aerobiseen suorituskykyyn …
2014
Tämän Pro gradu -tutkielman tarkoituksena oli selvittää varusmiespalveluksen kahdeksan viikkoa kestävän peruskoulutuskauden harjoittelun vaikutuksia varusmiesten veren rasva-arvoihin. Lisäksi tarkoituksena oli selvittää mielialan muutokset peruskoulutuskauden aikana sekä tutkia veren rasva-arvojen ja mielialan välistä yhteyttä. Lopuksi tutkittiin tupakoinnin vaikutuksia veren rasva-arvoihin ja mielialaan. Kahdeksan viikkoa kestäneeseen tutkimukseen osallistui 52 (ikä 19.5 ± 0.3 v.) vapaaeh-toista varusmiestä Kainuun Prikaatin viestikomppaniasta. Mittaukset ja kyselyt tehtiin peruskoulutuskauden alussa, keskivaiheilla sekä lopussa. Veren seerumista määritettiin kokonais-, LDL- ja HDL-koleste…
