Identifying childhood movement profiles and tracking physical activity and sedentary time across 1 year
2020
This study identified movement profiles in childhood and tracked longitudinal changes in moderate‐to‐vigorous physical activity and sedentary time across identified profiles. A sample consisted of 491 Finnish 5th Grade children (girls 275, boys 216; Mage = 11.27 ± .32). A latent profile analysis strategy was used to identify homogenous movement profiles that included measures of motor competence, perceived competence, and cardiorespiratory and muscular fitness. To examine a one‐year changes in moderate‐to‐vigorous physical activity and sedentary time among movement profiles, a mixed between‐within subjects analysis of variance with Tukey's post hoc ‐tests was conducted. Results revealed thr…
Peak oxygen uptake, ventilatory threshold, and arterial stiffness in adolescents
2018
Purpose To investigate the associations of peak oxygen uptake (V̇ O2peak) and V̇ O2 at ventilatory threshold (V̇ O2 at VT) with arterial stiffness in adolescents. Methods The participants were 55 adolescents (36 girls, 19 boys) aged 16–19 years. Aortic pulse wave velocity (PWVao) and augmentation index (AIx%) were measured by non-invasive oscillometric device from right brachial artery level. V̇ O2peak was directly measured during a maximal ramp test on a cycle ergometer. V̇ O2 at VT was determined using the equivalents for ventilation (V̇ E/V̇ CO2 and V̇ E/V̇ O2). V̇ O2peak and V̇ O2 at VT were normalised for body mass (BM) and lean mass (LM). Data were analysed using linear regression ana…
Activity Trackers Influencing Motivation and Awareness: Study Among Fitness Centre Members
2017
Consumer fitness technology products are becoming increasingly popular. This leads to interesting questions about the influence of activity trackers on a person’s motivation to exercise. This study explored the role of activity trackers in motivating fitness centre members towards exercising and in increasing their awareness regarding their own health and physical activity. The study included 100 fitness centre members divided into a test group and a control group and three sub-groups: OLD, NEW, and personal trainer (PT) members. The focus was on gym visit frequency during a 10-week test period and on tracking the consistency of activity levels. Participants also completed a pre and post st…
Predicting Adolescents’ Physical Activity Intentions : Testing an Integrated Social Cognition Model
2023
Abstract Background Few adolescents meet guideline levels of physical activity associated with good health, highlighting the need for intervention. Interventions promoting adolescents’ physical activity should be guided by research applying behavioral theory to identify potentially modifiable correlates and associated processes. We applied an integrated social cognition model to identify theory-based constructs and processes that relate to physical activity intentions in a secondary analysis of two samples of Finnish adolescents using a correlational design. Method Participants in the first sample (n = 455) completed self-report measures of social cognition constructs from theory of planned…
Heavy vs Light Load Single-Joint Exercise Performance with Different Rest Intervals
2017
Abstract The aim of the study was to compare the effect of three distinct rest period lengths between sets of upper body single-joint exercise with different load zones and volume designed for either endurance or hypertrophy (50% or 80% of 1-RM). Sixteen trained men (20.75 ± 2.54 years; 76.35 ± 5.03 kg; 176.75 ± 3.33 cm, 24.53 ± 1.47 kg/m2) performed a test and retest of 1-RM on non-consecutive days. Forty-eight hours after load testing, the participants were randomly assigned to six sessions consisting of four sets of the triceps pull-down, combining different intensities with distinct rest periods between sets. The shorter 1 minute rest promoted a significant reduction in the total repeti…
The effects of regular sauna bathing in conjunction with exercise on cardiovascular function : A multi-arm randomized controlled trial
2022
Regular exercise and sauna bathing have each been shown to improve cardiovascular function in clinical populations. However, experimental data on the cardiovascular adaptations to regular exercise in conjunction with sauna bathing in the general population is lacking. Therefore, we compared the effects of exercise and sauna bathing, to regular exercise using a multi-arm randomized controlled trial. Participants (n = 47) aged 49 ± 9 years with low physical activity levels, and at least one traditional CVD risk factor were randomly assigned (1:1:1) to guideline-based regular exercise and 15-minute post-exercise sauna (EXS), guideline-based regular exercise (EXE), or control (CON), for eight w…
Developmental associations of actual motor competence and perceived physical competence with health-related fitness in schoolchildren over a four-yea…
2022
The developmental associations between actual motor competence (MC), perceived physical competence (PC), and health-related fitness (HRF) in schoolchildren were investigated over a four-year period. Participants were 1147 (girls 582, boys 565) schoolchildren aged between 11 to 13 years (M = 11.27 ± 0.33 years) in the beginning of the study. Data were collected at five time points in 2017–2021. MC was measured with three product-oriented (i.e., outcome of the movement) motor competence skill tests: side-to-side jump, five-leaps, and throw-catch. PC was assessed with the Physical Self-Perception Profile. HRF was assessed with the 20m shuttle run, curl-up, and push-up tests. The random interce…
Effects of carbohydrate content on body composition during weight loss in female fitness competitors
2017
Introduction. Bodybuilders and fitness competitors are aiming to reduce fat mass and maintain lean mass during the competition phase. Low carbohydrate diets compared to low fat diets have claimed to be more effective in weight loss, but the results are still controversial. Low carbohydrate intake and high protein intake have been reported in bodybuilders during the diet, but the evidence of its effectiveness is limited. The aim of this study was to examine the effects of carbohydrate content on body composition during weight loss in female fitness competitors. Methods. A total of 50 female subjects participated in this study, 27 were competitors, and 23 were weight training stable controls.…
Supernaiset : kertomuksia fitness-harrastajien ihmisenä kehittymisestä
2016
Tämän tutkimuksen tarkoituksena on tarkastella alle 30 -vuotiaiden naisfitness-harrastajien ihmisenä kehittymistä fitness-harrastuksen aloittamisen jälkeen. Tutkimukseen osallistui 11 naispuolista fitness-harrastajaa, joista kuusi vastasi tutkimuskysymyksiin kirjallisesti ja viisi oli haastateltavana. Aineiston analyysissä on hyödynnetty narratiivisia tutkimusmenetelmiä, joiden avulla kertomukset on luokiteltu tarinatyyppeihin. Tulokseksi fitness-harrastajien kirjoitelmista muodostui kolme kerronnallisesti toisistaan eroavaa näkökulmaa. Tarinatyypit olivat nimeltään identiteetin löytäjä, elämänhallintataitojen rakentaja ja omakuvan uudistaja. Tutkimus osoitti fitness-harrastuksen vaikutuksi…
