Space, body, time and relationship experiences of recess physical activity: a qualitative case study among the least physical active schoolchildren.

Background: Increasing recess physical activity has been the aim of several interventions, as this setting can provide numerous physical activity opportunities. However, it is unclear if these interventions are equally effective for all children, or if they only appeal to children who are already physically active. This study was conducted to explore the least physically active children's "lived experiences" within four existential lifeworlds linked to physical activity during recess: space, body, time, and relations.

A Randomized, Controlled Trial of Total Knee Replacement.

Background: More than 670,000 total knee replacements are performed annually in the United States; however, high-quality evidence to support the effectiveness of the procedure, as compared with nonsurgical interventions, is lacking.

Methods: In this randomized, controlled trial, we enrolled 100 patients with moderate-to-severe knee osteoarthritis who were eligible for unilateral total knee replacement. Patients were randomly assigned to undergo total knee replacement followed by 12 weeks of nonsurgical treatment (total-knee-replacement group) or to receive only the 12 weeks of nonsurgical treatment (nonsurgical-treatment group), which was delivered by physiotherapists and dietitians and consisted of exercise, education, dietary advice, use of insoles, and pain medication.

High-intensity sprint training inhibits mitochondrial respiration through aconitase inactivation.

Intense exercise training is a powerful stimulus that activates mitochondrial biogenesis pathways and thus increases mitochondrial density and oxidative capacity. Moderate levels of reactive oxygen species (ROS) during exercise are considered vital in the adaptive response, but high ROS production is a serious threat to cellular homeostasis. Although biochemical markers of the transition from adaptive to maladaptive ROS stress are lacking, it is likely mediated by redox sensitive enzymes involved in oxidative metabolism.

Effects of a multi-component camp-based intervention on inflammatory markers and adipokines in children: A randomized controlled trial.

Objective: To examine the effects of a multi-component camp-based intervention on inflammatory markers and adipokines in children.

Methods: One hundred and fifteen children were recruited in Odense, Denmark (2012-2014). The participants were randomly allocated to either the day camp intervention arm (DCIA) or the standard intervention arm (SIA).

Objective: To develop a patient-reported outcome evaluating the impact of neck pain. The results of item generation and reduction and subscale structure in support of the content and construct validity of the measure are reported.

Methods: Items were generated from the literature and through focus groups including patients with neck pain and healthcare professionals, respectively.

Accelerometry-based monitoring of daily physical activity in children with juvenile idiopathic arthritis.

Objectives: Juvenile idiopathic arthritis (JIA) may cause functional impairment, reduced participation in physical activity (PA) and, over time, physical deconditioning. The aim of this study was to objectively monitor daily free-living PA in 10-16-year-old children with JIA using accelerometry with regard to disease activity and physical variables and to compare the data with those from healthy age- and gender-matched controls.

Method: Patients underwent an evaluation of disease activity, functional ability, physical capacity, and pain.

When Intervention Meets Organisation, a Qualitative Study of Motivation and Barriers to Physical Exercise at the Workplace.

Objective: To provide a comprehensive understanding of the motivational factors and barriers that are important for compliance with high-intensity workplace physical exercise that is aimed at reducing musculoskeletal disorders.

Method: The present study, which used semideductive, thematic, and structured in-depth interviews, was nested in a 20-week cluster randomised controlled trial among office workers. Interviews were conducted with 18 informants with diverse fields of sedentary office work who participated in strength training at the workplace for 20 minutes, three times per week.

Is aerobic workload positively related to ambulatory blood pressure? A cross-sectional field study among cleaners.

Purpose: Cardiovascular disease is prevalent among workers with high levels of occupational physical activity. The increased risk may be due to a high relative aerobic workload, possibly leading to increased blood pressure. However, studies investigating the relation between relative aerobic workload and ambulatory blood pressure (ABP) are lacking.

Characterizing the concept of activity pacing as a non-pharmacological intervention in rheumatology care: results of an international Delphi survey.

Objective: To develop a consensual list of the most important aspects of activity pacing (AP) as an intervention within the context of non-pharmacological rheumatology care.

Method: An international, multidisciplinary expert panel comprising 60 clinicians and/or healthcare providers experienced in AP across 12 different countries participated in a Delphi survey. Over four Delphi rounds, the panel identified and ranked the most important goals of AP, behaviours of AP (the actions people take to meet the goal of AP), strategies to change behaviour in AP, and contextual factors that should be acknowledged when instructing AP.
