The impact of experimental pain on shoulder movement during an arm elevated reaching task in a virtual reality environment.

Background: People with chronic shoulder pain have been shown to present with motor adaptations during arm movements. These adaptations may create abnormal physical stress on shoulder tendons and muscles. However, how and why these adaptations develop from the acute stage of pain is still not well-understood.

Physical Activity in Patients with Inflammatory Bowel Disease: A Cross-Sectional Study.

Introduction And Objective: Despite the known benefits of physical activity in the management of chronic diseases, the use of exercise as a treatment is relatively underemployed, with many patients reporting their disease to be a barrier. This study aimed to assess physical activity levels, attitudes, and barriers towards exercise in a cohort of patients with inflammatory bowel disease (IBD). In addition, this study aimed to assess possible relationships between physical well-being, psychological well-being, and sociodemographic factors.

Intermittent fasting, Paleolithic, or Mediterranean diets in the real world: exploratory secondary analyses of a weight-loss trial that included choice of diet and exercise.

Background: Intermittent fasting (IF) and Paleolithic (Paleo) diets produce weight loss in controlled trials, but minimal evidence exists regarding long-term efficacy under free-living conditions without intense dietetic support.

Objectives: This exploratory, observational analysis examined adherence, dietary intake, weight loss, and metabolic outcomes in overweight adults who could choose to follow Mediterranean, IF, or Paleo diets, and standard exercise or high-intensity interval training (HIIT) programs, as part of a 12-mo randomized controlled trial investigating how different monitoring strategies influenced weight loss (control, daily self-weighing, hunger training, diet/exercise app, brief support).

Methods: A total of 250 overweight [BMI (in kg/m2) ≥27] healthy adults attended an individualized dietary education session (30 min) relevant to their self-selected diet.

Detailed Multi-Dimensional Assessment of Fatigue in Inflammatory Bowel Disease.

Background: Fatigue is a symptom commonly reported by patients with inflammatory bowel disease (IBD). Treating any underlying inflammation in active disease improves the health outcomes and decreases fatigue, but fatigue still persists in remission, negatively affecting patients' quality of life and posing a challenge for the treating physician. The aim of this study was to describe the prevalence of fatigue in patients with IBD and investigate possible contributing factors.

High-Intensity Interval Training in the Real World: Outcomes from a 12-Month Intervention in Overweight Adults.

Purpose: Although high-intensity interval training (HIIT) and moderate-intensity continuous exercise have comparable health outcomes in the laboratory setting, effectiveness studies in real-world environments are lacking. The aim of this study was to determine the effectiveness of an unsupervised HIIT program in overweight/obese adults over 12 months.

Methods: Two hundred and fifty overweight/obese adults could choose HIIT or current exercise guidelines of 30 min·d moderate-intensity exercise.

The Effect of Different Types of Monitoring Strategies on Weight Loss: A Randomized Controlled Trial.

Objective: To determine the effectiveness of various monitoring strategies on weight loss, body composition, blood markers, exercise, and psychosocial indices in adults with overweight and obesity following a 12-month weight loss program.

Methods: Two hundred fifty adults with BMI ≥ 27 were randomized to brief, monthly, individual consults, daily self-monitoring of weight, self-monitoring of diet using MyFitnessPal, self-monitoring of hunger, or control over 12 months. All groups received diet and exercise advice, and 171 participants (68.

Drug misuse in sport: a New Zealand perspective.

Aims: Drug misuse in elite sport is a world-wide phenomenon. This article explores the culture of contemporary sport, provides estimates of doping prevalence, discusses dietary supplementation and highlights major factors influencing high-performance athletes and their support personnel. The aim is to stimulate discussion, informed by the World Anti-Doping Code (WADC), which is particularly relevant to doctors caring for athletes.

Australasian College of Sports Physicians-position statement: the place of mesenchymal stem/stromal cell therapies in sport and exercise medicine.

This Position Statement has been written expressly for members of the Australasian College of Sports Physicians (ACSP); however, it may also be of interest to the wider medical community, sporting organisations, athletes and the general community. It has been informed by a comprehensive review of the scientific literature and the opinions of kindred organisations. This statement outlines the use of mesenchymal stem cell (MSC) therapies in the broad context of Sport and Exercise Medicine, recognising that every medical practitioner should respect: (1) the evidence for the therapeutic use of MSCs and (2) the priority for patient health and welfare.

Determining how best to support overweight adults to adhere to lifestyle change: protocol for the SWIFT study.

Background: Physical activity plays a critical role in health, including for effective weight maintenance, but adherence to guidelines is often poor. Similarly, although debate continues over whether a "best" diet exists for weight control, meta-analyses suggest little difference in outcomes between diets differing markedly in macronutrient composition, particularly over the longer-term. Thus a more important question is how best to encourage adherence to appropriate lifestyle change.

The effect of experimentally-induced subacromial pain on proprioception.

Shoulder injuries may be associated with proprioceptive deficits, however, it is unknown whether these changes are due to the experience of pain, tissue damage, or a combination of these. The aim of this study was to investigate the effect of experimentally-induced sub-acromial pain on proprioceptive variables. Sub-acromial pain was induced via hypertonic saline injection in 20 healthy participants.

Electromyographic response of shoulder muscles to acute experimental subacromial pain.

This study investigated effects of experimentally-induced subacromial pain, induced via hypertonic saline injection, on shoulder muscles activity. Electromyographic activity of 20 healthy participants was assessed for humeral elevation and descent for the control and experimental pain conditions, using fine wire electrodes for subscapularis and supraspinatus and surface electrodes for middle deltoid, upper trapezius, lower trapezius, infraspinatus, and serratus anterior. Normalized mean amplitudes were analyzed for each muscle for four phases for elevation and descent, respectively.

Clinical measurement of scapular upward rotation in response to acute subacromial pain.

Study Design: Block-counterbalanced, repeated-measures crossover study.

Objectives: To assess scapular upward rotation positional adaptations to experimentally induced subacromial pain.

Background: Existing subacromial pathology is often related to altered scapular kinematics during humeral elevation, such as decreased upward rotation and posterior tilting.

Hip abduction weakness in elite junior footballers is common but easy to correct quickly: a prospective sports team cohort based study.

Background: Hip abduction weakness has never been documented on a population basis as a common finding in a healthy group of athletes and would not normally be found in an elite adolescent athlete. This study aimed to show that hip abduction weakness not only occurs in this group but also is common and easy to correct with an unsupervised home based program.

Methods: A prospective sports team cohort based study was performed with thirty elite adolescent under-17 Australian Rules Footballers in the Australian Institute of Sport/Australian Football League Under-17 training academy.

Insulin and fiber type in the offspring of T2DM subjects with resistance training and detraining.

Purpose: Effects of resistance training and detraining on glucose and insulin responses to an oral glucose load, muscle fiber type, and muscular performance in the offspring of those with type 2 diabetes (familial insulin resistant (FIR)) were investigated.

Methods: Six FIR participants and 10 controls (C) completed 9 wk of resistance training and 9 wk of detraining. Measures of strength and power, an oral glucose tolerance test, and a muscle biopsy to determine myosin heavy chain (MHC) fiber composition were taken at baseline (T1), after training (T2), and after detraining (T3).

The role of experimentally-induced subacromial pain on shoulder strength and throwing accuracy.

Shoulder injuries often comprise two separate yet related components, structural tissue damage and pain. The role of each of these components on shoulder function is difficult to ascertain. Experimental pain models allow the assessment of consequences of localized pain when applied to healthy individuals.
