Physical Activity and Physical Competence in Overweight and Obese Children: An Intervention Study
2020
With the current obesity epidemic and the decline of fitness among school-aged children, the importance of obesity interventions to promote physical activity and healthy habits has become indisputable. The purpose of this study was to assess the efficacy of a school-based multicomponent intervention in increasing physical activity (PA) levels, actual physical abilities, and perceived physical abilities in clinical and nonclinical samples of overweight/obese boys and girls aged 10–12 years. The clinical intervention group (n = 35) participated in a 7-month after-school program in addition to curricular physical education lessons, while the nonclinical control group (n = 29) received usual cu…
Promoting Physical Activity Habits after Completing Secondary School: Does the Age Matter?
2022
Physical inactivity is one of the most important problems in our society, especially during adolescence. During this stage of schooling, students practice physical activity in physical education classes, but after they finish school, many of them stop practicing it. This research aims to determine which variables predict the intention to practice physical activity after finishing secondary school and to discover the effect that age during adolescence has on these predictive variables. A questionnaire was administered to a sample of secondary school students. The results show that physical exercise identity influences the three antecedents of this theory, while the attitude towards the behav…
Concurrent and construct validation of a new scale for rating perceived exertion during elastic resistance training in the elderly
2020
Purpose:\ud To examine the concurrent and construct validity of a new perceptual scale to control the exercise intensity using elastic bands (Resistance Intensity Scale for Exercise; RISE) in the elderly.\ud \ud Methods:\ud Twenty-six participants underwent two sessions consisting of 4 exercises. The participants performed three sets of 15 repetitions per exercise of either low, medium, or high intensity. The criterion variables were heart rate and applied force (mean and peak). Following the final repetition of each set, active muscle (AM) and overall body (OB) ratings of perceived exertion (RPE) were collected from RISE and the OMNI-Resistance Exercise Scale of perceived exertion with ela…
A biomechanical comparison of countermovement performance after short-term traditional and daily-undulated loaded vertical jump training.
2017
In order to assess lower extremity muscle mechanical properties in athletes, power-load characteristics during multi-joint tasks are frequently examined. This work compared 6 weeks of traditional (TP) and daily-undulated (DUP) periodized loaded countermovement jumping (CMJ). 20 amateur athletes (age: 24.2 ± 2.6 years, height: 175.6 ± 7.1 cm, body mass: 71.5 ± 7.7 kg, 10 males/10 females) exercised three times weekly using maximal CMJs with loads corresponding to 0%, 15% and 30% of body mass. Prior to the training period, subjects were once-only assigned by random to either the TP or DUP training scheme. Pre-to-post training, maximal center of mass (COM) -height, -take-off velocity, -power o…
Changes in Physical Performance During 21 d of Military Field Training in Warfighters.
2018
Introduction Few studies have reported the amount of physical activity (PA) and its associations to physical performance of warfighters during military field training (MFT). The purpose of this study was to investigate changes in neuromuscular performance and PA among male Finnish Army conscripts during a 21-d MFT and to evaluate their recovery during 4 d after MFT. Methods Body composition and physical performance were measured four times during the study (before MFT (PRE), after 12 d (MID), post training (POST) and after 4 d of recovery (RECO)). PA was measured throughout MFT in a group of healthy young male conscripts (n=49) by using a tri-axial accelerometer. The study was approved by t…
Adverse metabolic response to regular exercise: Is it a rare or common occurrence?
2012
Background. Individuals differ in the response to regular exercise. Whether there are people who experience adverse changes in cardiovascular and diabetes risk factors has never been addressed. Methodology/Principal Findings. An adverse response is defined as an exercise-induced change that worsens a risk factor beyond measurement error and expected day-to-day variation. Sixty subjects were measured three times over a period of three weeks, and variation in resting systolic blood pressure (SBP) and in fasting plasma HDL-cholesterol (HDL-C), triglycerides (TG), and insulin (FI) was quantified. The technical error (TE) defined as the within-subject standard deviation derived from these measur…
Older adults show elevated intermuscular coherence in eyes‐open standing but only young adults increase coherence in response to closing the eyes
2020
New Findings: What is the central question of this study? Can a 14-week strength-training programme modify intermuscular coherence levels during bipedal standing tasks with eyes open and eyes closed and reduce age-related differences? What is the main finding and its importance? Older adults had more prominent common input over 4–14 Hz with eyes open, but during the eyes-closed task the young adults were able to further enhance their common input at 6–36 Hz. This indicates that young adults are better at modulating common input in different motor tasks. Abstract: Understanding neural control of standing balance is important to identify age-related degeneration and design interventions to ma…
Resistance exercise with different workloads have distinct effects on cellular respiration of peripheral blood mononuclear cells
2022
Little is known how acute exercise-induced inflammation and metabolic stress affect immune cell bioenergetics and the portion of its components. Therefore, we investigated acute effects of eccentric-only (E), concentric-only (C) and combined eccentric-concentric resistance exercise (E + C) bouts on cellular respiration of peripheral blood mononuclear cells (PBMCs). Twelve strength-trained young men performed bench press resistance exercises in randomized order. Venous blood samples were drawn at pre-, 5 min post- and 24 h post-exercise. Several PBMC respiration states were measured using high-resolution respirometry. Levels of leukocytes, interleukin 6 (IL-6), C-reactive protein (CRP), crea…
Fun, influence and competence—a mixed methods study of prerequisites for high school students’ participation in physical education
2016
Background: Many adolescents do not reach the recommended levels of physical activity (PA), and students attending vocational studies are less committed to take part in physical education (PE) than other students. The purpose of the present study was twofold: 1) to examine differences in physical activity, diet, smoking habits, sleep and screen time among Norwegian vocational high school students who selected either a PE model focusing on PA skills, technique and improvement of physical performance (“Sports enjoyment”) or more on health, play and having fun when participating in PE lessons (“Motion enjoyment”), and 2) to explore the students’ experiences with PE programs. Methods: In this m…
Associations among Basic Psychological Needs, Motivation and Enjoyment within Finnish Physical Education Students
2018
The purpose of this study was to analyse the associations between basic psychological needs, motivational regulations and enjoyment within Finnish physical education (PE) students. The participants of the study were 260 Grade 5 students (Mage=11.86, SD=0.28) and 242 Grade 8 students (Mage=14.93, SD=0.37) who completed a questionnaire prior to their regular PE classes. This cross-sectional study incorporated a multigroup structural equation modelling (SEM, path model) separately for Grade 5 and 8 students, using gender as a grouping value. Results indicated that among Grade 5 students autonomy was directly associated with enjoyment. In addition, there was an indirect path from autonomy to en…
