Objective: Previously, we have found increased carotid-to-femoral pulse wave velocity (cfPWV) among shift workers compared to day workers in industry, and a decline in maximal oxygen uptake (V̇O 2max ) in all 86 workers.

Methods: Utilizing all available measurements in 2018, 2021, and 2022, this study investigated associations between V̇O 2max and measures of arterial stiffness. Using a mixed model approach, we analyzed the cross-sectional association between all V̇O 2max (outcome) and measures of arterial stiffness (covariates).

Background: We aimed to determine if maximal oxygen uptake (V˙Omax), resting heart rate (RHR), and self-reported leisure- time moderate to vigorous physical activity (MVPA) changed over a 3-year follow-up (FU) among industrial workers.

Methods: We assessed cardiorespiratory fitness (CRF) August 2018 and August 2021. The last 17-18 months coincided with the COVID-19 pandemic.

Introduction: The COVID-19 pandemic and infection control measures caused changes to daily life for most people. Heavy alcohol consumption and physical inactivity are two important behavioral risk factors for noncommunicable diseases worldwide. The COVID-19 pandemic, with its social distancing measures, home office policies, isolation, and quarantine requirements may have an impact on these factors.

Article Synopsis
  • The study aimed to evaluate changes in cardiovascular disease risk factors over three years among rotating shift workers compared to day workers in an industrial setting.
  • Methods included surveys for demographics and various health metrics (blood pressure, heart rate, etc.), along with blood tests for lipids and inflammation markers, analyzed using statistical models.
  • Results indicated that shift workers had higher levels of certain adhesion molecules and experienced a significant increase in arterial stiffness compared to day workers, suggesting potential increased risks for cardiovascular disease.

This article explores, systematically and in depth, users' perceptions of participating in a Norwegian non-profit establishment that provides a continuing care programme for substance use and dependence. Identified results are linked to a holistic system perspective, where human, technology, and organisation (HTO), as well as external environment, are viewed as intertwined. At the establishment level, i.

The increased prevalence of non-communicable disease risk factors among children because of lack of physical activity is concerning. The Health Oriented Pedagogical Project was set up to combine learning activities and physical activity, thus reducing sedentariness during school time. The current study aimed to measure and describe the longitudinal and cross-sectional development of oxygen uptake and running performance in children at ages six and ten.

There is a lack of data describing the blood pressure response (BPR) in well-trained individuals. In addition, continuous bio-signal measurements are increasingly investigated to overcome the limitations of intermittent cuff-based BP measurements during exercise testing. Thus, the present study aimed to assess the BPR in well-trained individuals during a cycle ergometer test with a particular focus on the systolic BP (SBP) and to investigate pulse arrival time (PAT) as a continuous surrogate for SBP during exercise testing.

Background: Use of physical activity in the treatment and follow-up of people receiving opioid substitution therapy is an understudied area of research. Therefore, the objective of this systematic review was to synthesize the currently available research on the role of physical activity in opioid substitution therapy and proper adaptions for the group.

Methods: A systematic search was performed on PsycINFO, EMBASE, MEDLINE, CINAHL, and Web of Science until September 2021 (PROSPERO-reg.

Unlabelled: Background The purpose of the study was to examine differences in objectively measured moderate-to-vigorous physical activity (MVPA min/day) and sedentary time (SED min/day) between different time domains as school hours, leisure time, and weekends. An additional objective addressed causal association between body mass and MVPA.

Methods: The study sample consisted of 2015 subjects (51% girls) aged 6-12 years (9.

Background: To try out the feasibility of presenting the health status of children 6 to 12 years old by using radar plots.

Methods: With data from the Health Oriented Pedagogical Project (HOPP) we have described the health status for 1340 children aged 6 to 12 years. We collected or calculated: stature, body mass, waist circumference, waist to height ratio, high density lipoprotein (HDL) and total cholesterol concentration, blood pressure, accelerometer assessed physical activity, endurance interval running performance, and quality of life.

It is commonly known that children do not engage in a sufficient amount of physical activity. Weather conditions and day length may influence physical activity of children. Little is known about the relationship between physical activity and seasons.

There is a plausible association between shift work and cardiovascular disease (CVD), which may be due to disruption of the circadian rhythm causing hormonal changes and metabolic disturbances, resulting in high blood pressure, atherosclerosis, diabetes, and being overweight. However, few studies have investigated the association between several consecutive long work shifts, including night shifts, and risk factors for developing CVD. Moreover, knowledge is lacking on factors that may modify or enhance this suggested relationship.

Monitoring and assessment of the development of motor skills is an important goal for practitioners in many disciplines as well as researchers interested in motor development. A well-established tool for such purpose is the (MABC-2) which covers three age ranges and contains eight motor items in each range related to the manual dexterity, aiming and catching, and balance. The main aim of the study was to investigate the reliability and validity of the MABC-2 age band one in a sample of Croatian preschool children.

We compared the fitness levels of cohorts of 15-year-old youth in 1988 and 2001 to ascertain whether there was a negative trend in fitness. The subjects were 15-year-old boys and girls from the same geographical area, n = 192 in 1988 and n = 191 in 2001. They participated voluntarily and could leave the project whenever they wished.

There is an abundance of literature reporting an association between shift work and cardiovascular disease (CVD). Few studies have examined early manifestation of CVD using advanced modern methodology. We established a group of 65 shift workers and 29 day workers (controls) in two industrial plants.

The aim of the present study was to investigate the performance and aerobic endurance effects of high-intensity (HICR) versus moderate-intensity continuous running (MICR), which were nonmatched for total work. Twenty healthy recreational athletes (aged 28 ± 5 years) were randomly assigned to an HICR, MICR, or no-intervention control (C) group. The HICR group ( = 7) performed a 20-min strenuous, almost exhausting, run above lactate threshold (LT) at ∼88% of maximal heart rate (HR), whereas the MICR group ( = 7) performed a 40-min run at ∼80% HR.

Background: People with severe mental illness have markedly reduced life expectancy; cardiometabolic disease is a major cause. Psychiatric hospital inpatients have elevated levels of cardiometabolic risk factors and are to a high degree dependent of the routines and facilities of the institutions. Studies of lifestyle interventions to reduce cardiometabolic risk in psychiatric inpatients are few.

Aims: The primary aim of the present study was to evaluate the association between parents' level of education, measurements of physical attributes, and quality of life in a general sample of primary school children.

Methods: The children's and the parents' versions of the Inventory of Life Quality in Children and Adolescents (ILC) were used to measure health-related quality of life (QOL) in 2140 school children (response rate 93%) and 1639 parents (response rate 71%) recruited from nine primary schools in Norway. A set of physical characteristics were also measured in the children: body mass index (BMI), waist circumference, average daily minutes of physical activity, aerobic fitness, and handgrip strength.

Aims: As children's fitness continues to decline, frequent and systematic monitoring of fitness is important. Easy-to-use and low-cost methods with acceptable accuracy are essential in screening situations. This study aimed to investigate how the measurements of body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR) relate to selected measurements of fitness in children.
