Fitness and lean mass increases during combined training independent of loading order.
2014
Although the benefits of combined endurance (E) and strength (S) training for the development of physical fitness and health are well known, scientific examination of the effect of loading order when E and S are combined into the same training session (E+S vs S+E) is rare. This study investigated the effects of moderate frequency E+S versus S+E training on physical fitness, body composition, and blood lipids.Physically active and healthy young men performed E+S (n = 16) or S+E (n = 18) training 2-3 times a week for 24 wk. Endurance (by incremental bike test) and strength (by dynamic leg press) performance as well as body composition (by dual-energy x-ray absorptiometry), muscle cross-sectio…

Fitnessurheilijoiden kehonkoostumus, lihaskoko ja hormonitasapaino kilpailudieetillä ja palautumisjaksolla
2017
Ville Isola, 2017. Fitnessurheilijoiden kehonkoostumus, lihaskoko ja hormonitasapaino kilpailudieetillä ja palautumisjaksolla. Liikuntabiologia, liikuntatieteellinen tiedekunta, Jyväskylän yliopisto. Valmennus- ja testausoppi, pro gradu-tutkielma 95s. 2 liitettä. Fitness-lajit ovat kasvattaneet suosiotaan viime vuosina räjähdysmäisesti. Aiheen suuresta kiinnostuksesta huolimatta tieteellistä tutkimusta fitnessurheilijan kilpailudieetistä tai sen palautumisjaksosta ei ole juurikaan saatavilla, lukuun ottamatta muutamia tapaustutkimuksia. Tämän tutkimuksen tarkoituksena oli selvittää muuttuvatko fitnessurheilijoiden kehonkoostumus ja lihaskoko, lihasten voimantuotto sekä hormonitasapaino kilp…
Fyysisen kunnon ja kehonkoostumuksen yhteydet kehon syvälämpöön palomiehen työnomaisessa suorituksessa
2018
Fyysisesti raskainta palomiehen työtehtävistä on savusukellus- ja raivaustehtävä. Se aiheuttaa suuret vaatimukset hengitys- ja verenkiertoelimistölle ja kuormittuneisuus voi yltää lähelle maksimaalista hapenkulutusta (VO2max). Lisäksi joudutaan kantamaan ja käsittelemään raskaita taakkoja, jolloin lihaksisto ja muut liikuntaelimet joutuvat kovaan rasitukseen. Käytettävä monikerrosvaatetus ja muut suojavarusteet suojaavat ulkoiselta kuumuudelta, mutta voi aiheuttaa ylikuormitusta kehon syvälämmön noustessa. Syvälämmön voimakkaasta noususta voi seurata lämpöuupumus tai jopa lämpöhalvaus. Tutkimuksen tarkoituksena oli saada selville korreloiko kehon syvälämpö kuntotekijöiden ja kehonkoostumuks…
Diet Macronutrient Composition, Physical Activity, and Body Composition in Soldiers During 6 Months Deployment
2019
Introduction: Optimal diet together with good physical fitness maintains readiness and military performance during longer deployments. The purpose of this study was to describe changes in dietary macronutrient and energy intake, total physical activity and body composition during a 6-month deployment in South Lebanon. Furthermore, associations of diet macronutrient intake and physical activity on body composition were also studied. - Materials and Methods: Forty male soldiers kept a 3-day food diary and their body composition was measured via bioimpedance and ultrasonography. Total physical activity was evaluated by accelerometers in a subgroup of participants. Measurements were conducted i…
The effects of muscle mass and muscle quality on cardio-metabolic risk in peripubertal girls: a longitudinal study from childhood to early adulthood.
2017
Increased cardio-metabolic risk is well documented in children and adolescents with obesity and normal weight obesity (NWO). However, the associations of muscle mass and muscle quality with cardio-metabolic risk, independent of weight status from childhood to adulthood, has not been examined. A total of 236 girls were followed from pre-puberty to early adulthood. Fat mass (FM) and lean mass (LM) of the whole body were assessed by a dual-energy X-ray absorptiometry; muscle cross-sectional area (mCSA), muscle density (mDen; skeletal muscle fat content) of the lower leg by the peripheral quantitative computerized tomography; and blood glucose, insulin, triglycerides and high-density lipoprotei…
Cross-sectional associations of objectively-measured physical activity and sedentary time with body composition and cardiorespiratory fitness in mid-…
2017
Abstract Background The minimum intensity of physical activity (PA) that is associated with favourable body composition and cardiorespiratory fitness (CRF) remains unknown. Objective To investigate cross-sectional associations of PA and sedentary time (ST) with body composition and CRF in mid-childhood. Methods PA, ST, body composition and CRF were measured in a population-based sample of 410 children (aged 7.6 ± 0.4 years). Combined heart-rate and movement sensing provided estimates of PA energy expenditure (PAEE, kJ/kg/day) and time (min/day) at multiple fine-grained metabolic equivalent (MET) levels, which were also collapsed to ST and light PA (LPA), moderate PA (MPA) and vigorous PA (V…
Effects of an 8-day field training on body composition, serum hormone concentrations and maximal force production in military conscripts

Savolainen, S. 2015. Effects of an 8-day field training on body composition, serum hormone concentrations and maximal force production in military conscripts, 64p. University of Jyväskylä. Department of Biology of Physical Activity. Science of Sports Coaching and Fitness Testing. The aim of this study was to examine physiological consequences on 8-day strenuous military field exercise. 26 men (20 ± 1 yrs, 53,7 ± 4,5ml/kg/min, 178,4 ± 7,2cm, 71,2 ± 7,2kg) in the end of their military service participated in the study. The research data was collected in five testing day (pre1, pre2, middle, post and follow-up); body composition, physical performance and basal blood levels were measured. The c…
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.

Mitatun fyysisen kunnon sekä kehonkoostumuksen yhteys työperäiseen stressiin ylipainoisilla, liikuntaa harrastamattomilla henkilöillä
2013
TIIVISTELMÄ Mitatun fyysisen kunnon sekä kehonkoostumuksen yhteys työperäiseen stressiin ylipainoisilla, liikuntaa harrastamattomilla henkilöillä Maaria Mäkitervo Jyväskylän yliopisto Liikuntatieteellinen tiedekunta Terveystieteiden laitos Syksy 2013 53 sivua, 9 liitettä Työperäinen stressi on eräs työelämän keskeisimmistä haasteista ja sillä on mittavat vaikutukset terveydenhuollon kustannuksiin. Stressillä tiedetään olevan kiistaton vaikutus sydämen sykevaihteluun ja liikunnan on todettu laukaisevan stressiä ja parantavan sykevaihtelua. Näin voidaan tarkastella yksilön aerobisen kunnon vaikutusta sykevaihtelun kautta työperäisen stressin ilmentymiseen ja kokemiseen. Tämän pro gradu -tutki…
