Associations of Cardiorespiratory Fitness and Adiposity With Arterial Stiffness and Arterial Dilatation Capacity in Response to a Bout of Exercise in…

2019

Purpose: To investigate the associations of directly measured peak oxygen uptake (V˙O2peak) and body fat percentage (BF%) with arterial stiffness and arterial dilatation capacity in children. Methods: Findings are based on 329 children (177 boys and 152 girls) aged 8–11 years. V˙O2peak was assessed by a maximal cardiopulmonary exercise test on a cycle ergometer and scaled by lean body mass (LM). BF% and LM were measured by bioelectrical impedance. Stiffness index (measure of arterial stiffness) and change in reflection index (ΔRI, measure of arterial dilatation capacity) were assessed by pulse contour analysis. Data were analyzed by linear regression models. Results: VO2peak/LM was positive…

Brain, cognition and physically active lifestyle in healthy ageing

2018

Normal ageing is accompanied by profound changes in brain structure and declines in the automatic processing of sensory stimuli, which in turn lead to altered cognitive performance. However, behaviour and lifestyle factors, such as physical activity, may help to maintain the brain’s structural connectivity and function, as well as cognitive functioning in old age. Study I examined the effects of age on the brain’s capability to detect changes in somatosensory stimuli by recording event-related potentials (ERPs) in response to electrical stimulation of different fingers in young and older adults. The results of Study I show that somatosensory mismatch response (sMMR) was attenuated in amplit…

Survival of the Fittest? Examining Lapsing Behaviour in the Context of Elderly People and the Use of Physical Activity Tracker Applications

2022

Physical activity (PA) tracker applications have been proposed as one potential solution to the increasingly prevalent physical inactivity problem among elderly people, but their long-term potential is limited by the frequent lapses in their use. In this study, our objective is to promote the understanding of the lapsing behaviour of PA tracker applications among elderly people. More specifically, we are interested in how gender, age, and household type as well as initial PA level and technology readiness (TR) affect the risk of lapsing. As the data for the study, we use actual PA tracker application usage data as well as survey data, which were both collected in our ongoing research progra…

Effects of 24 weeks of single session combined strength and endurance training on body composition and fitness : examination of order effect

2013

Küüsmaa, Maria 2013. Effects of 24 weeks of single session combined strength and endurance training on body composition and fitness: examination of order effect. Department of Biology of Physical Activity, University of Jyväskylä. Master’s Thesis in Science of Sport Coaching and Fitness Testing. 82 pp. Endurance and strength training are often performed concurrently. The question of whether the order of exercise yields to different adaptations in body composition, when strength (S) and endurance training (E) are combined into the same training session, has received only limited scientific attention. In addition, neuromuscular and cardiorespiratory adaptations to single session combined trai…

Physical activity during pregnancy and early childhood from the perspective of gestational diabetes risk and children's body composition

2017

This study investigated the factors associated with self-reported leisure-time physical activity excluding household activities (LTPAexHH) among women at risk for gestational diabetes (GDM), change in self-reported LTPA including household activities (LTPAinHH) from pre-pregnancy to 7-year follow-up as well as the influence of risk for GDM on their children’s physical activity (PA) and body composition. The association between maternal and child PA, and associations of PA with body composition and physical fitness in preschoolers were also studied. A sample of 399 pregnant women at risk for GDM was examined in a cohort study, and 199 mother-child dyads were assessed in cross-sectional and l…

Relationships of BMI, muscle-to-fat ratio, and handgrip strength-to-BMI ratio to physical fitness in Spanish children and adolescents

2023

AbstractThis study aimed to determine the relationship of body mass index (BMI), muscle-to-fat ratio (MFR), and handgrip strength-to-BMI ratio to physical fitness parameters in an active young population according to sex across four different time points. A total of 2256 Spanish children and adolescents (aged 5–18) from rural areas participating in an extracurricular sport in different municipal sports schools participated in this study. Participants were divided into children (5–10 years) and adolescents (11–18 years), boys and girls, and across four different time points (2018, 2019, 2020, 2021). Data on anthropometric measures (BMI, MFR, appendicular skeletal muscle mass) and physical fi…

Associations of cardiometabolic risk factors with heart rate variability in 6‐ to 8‐year‐old children : The PANIC Study

2020

Background Associations of cardiometabolic risk factors with heart rate variability (HRV) in children are unclear. We examined associations of cardiometabolic risk score (CRS) and individual cardiometabolic risk factors with HRV variables in 6‐ to 8‐year‐olds. Methods The participants were a population‐based sample of 443 children participating in baseline measurements of the Physical Activity and Nutrition in Children trial. Cardiometabolic risk factors included waist circumference (WC), insulin, glucose, triglycerides, HDL cholesterol, systolic blood pressure (SBP), and diastolic blood pressure (DBP). CRS was calculated as WC + insulin + glucose + triglycerides − HDL cholesterol + the mea…

Device-Based Measures of Sedentary Time and Physical Activity Are Associated With Physical Fitness and Body Fat Content

2020

Introduction/Purpose: Physical activity and sedentary time may associate with physical fitness and body composition. Yet, there exists some observational studies that have investigated the associations of device-based measures of sedentary time and physical activity (PA) with cardiorespiratory fitness (CRF) and body composition but associations with muscular fitness (MF) are less studied. Methods: Objective sedentary time and physical activity was measured by a hip worn accelerometer from 415 young adult men (age: mean 26, standard deviation 7 years). Cardiorespiratory fitness (VO2max) (CRF) was determined using a graded cycle ergometer test until exhaustion. Maximal force of lower extremit…
