Do Obese Children Achieve Maximal Heart Rate during Treadmill Running?
2019
Objective: Maximal heart rate (HR) is commonly defined as the highest HR obtained during a progressive exercise test to exhaustion. Maximal HR is considered one of the criteria to assess maximum exertion in exercise tests, and is broadly used when prescribing exercise intensity. The aim of the present study was to compare peak HR measurements during maximal treadmill running and active play in obese children and adolescents. Design: Comparison of peak heart rate during active play vs. maximal treadmill running in 39 (7&ndash
Effect of aerobic exercise on insulin resistance and central adiposity disappeared after the discontinuation of intervention in overweight women
2016
Purpose: This study aimed to assess whether the benefits of exercise on central adiposity and insulin resistance (HOMA-IR) are maintained after discontinuation of intervention in the overweight/obese (OWOB) women. Methods: The study subjects were from 2 independent studies with similar aerobic exercise (AE) intervention programs. In study I, 15 OWOB postmenopausal women with pre-diabetes (body mass index, BMI = 24–33 kg/m2 , aged 52–65 years) completed an 8-month exercise intervention and were followed for 2 years after the intervention. In study II, 12 OWOB (BMI = 25–35 kg/m2 , aged 30–50 years) premenopausal women participated in a 6-week AE and were followed for 4 years after the interve…

Reliability and validity of time domain heart rate variability during daily rout¡ne activities : an alternative to the morning orthostatic test?
2017
Summary Study aim: To determine the reliability and validity of a time domain heart rate variability (HRV) index during free-living physical activity (FLPA). Material and methods: Eight white-collar workers participated in this study. RR intervals (time between consecutive R-peaks of the PQRS complex) were recorded using the Polar V800 heart rate (HR) monitor upon awakening and at work on 16 different days. A total of 127 cycles of sitting periods followed by walking breaks were included for consecutive pairwise analysis for reliability. The HR values from the orthostatic test (OT) were compared with the corresponding values at work. Results: The HR values showed high levels of repeatabilit…
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…
Pienryhmäohjaajien vertaisryhmä andragogisessa koulutuksessa
2014
Erilaisten yhteistyön muotojen, vuorovaikutuksen ja jakamisen merkitystä korostetaan tutkimuksissa, mutta opettajien ja ohjaajien kollegiaalisen tuen muotoja ei juurikaan edistetä rakenteellisin tai organisatorisin keinoin. Vertaistuki vahvistaa ohjaajien työssä kehittymistä ja jaksamista sekä koulutuksen kehittämistä.
Onnellisia opiskelijoita keskellä poliittista muutosta : Tarton yliopistossa opiskelleiden virolaisten muistot Viron uudelleenitsenäistymistä edeltän…
2017
Neuvostoliiton hajoamisesta ja sitä kautta Viron uudelleenitsenäistymisestä tuli vuonna 2016 kuluneeksi 25 vuotta. Näiden vuosien aikana virolaiset muiden entisten neuvostokansojen tavoin ovat käyneet läpi neuvostomenneisyyttään ja tuolloisista nuorista aikuisista on kasvanut se sukupolvi, joka on nykyisessä Virossa päättävässä asemassa ja siirtää historiakäsityksiään uusille, itsenäisessä Virossa syntyneille sukupolville. Maisterintutkielmassani tutkin miten tämä 1960- ja 1970-lukujen taitteessa syntynyt sukupolvi muistaa 1980- ja 1990-lukujen taitteen tapahtumat ja heidän oman sukupolvensa roolin niissä. Kyseistä aikaa käsittelevä historiankirjoitus on tavallisesti keskittynyt makrotason …

MRI findings and physical performance as predictors of flight-induced musculoskeletal pain incidence among fighter pilots
2017
Summary Study aim: The aim of this study was to evaluate the possible association of pre-career magnetic resonance imaging (MRI) findings and physical performance level with possible musculoskeletal disorders during jet flight training. Material and methods: The study group consisted of 73 fighter pilots who had undergone pre-career cervical and lumbar spine MRI. Physical performance of a subgroup of the pilots (n = 67) was measured initially at the same time and followed up to the fast jet training phase (ranging from 3.8 to 7.0 years). Musculoskeletal pain history during pilot training was taken from the medical charts. MRI findings and physical performance were associated with perceived…
Influence of Aerobic Exercise After Static Stretching on Flexibility and Strength in Plantar Flexor Muscles
2020
Aerobic exercise could improve stretch-induced strength deficits. However, mechanisms of the improvement were unclear. The purpose of the study was to examine the effects of aerobic exercise after static stretching (SS) on flexibility and isometric strength in ankle plantar-flexor muscles. Fifteen healthy males received two interventions after SS of their ankle plantar-flexor muscles for 5 min. One was aerobic exercise for 10-min on a cycling ergometer, and the other was a 10-min rest as a control. Range of motion (ROM) of ankle dorsiflexion, passive torque at terminal ROM, muscle-tendon unit (MTU) stiffness, muscle tendon junction displacement, peak torque of ankle plantarflexion, and the …
