Context: Caregivers of People Living with Dementia (PLWD) face multiple challenges in their caregiving role where the informal care provided by the caregivers of PLWD in Canada has a financial burden on the total out-of-pocket costs of $1.4 billion. In addition, it takes 1.5 times more informal care time for caregivers of PLWD than other informal c...

Sleep duration improves short-term following bariatric surgery; however, little is known about its association with bodyweight medium- to long-term post-surgery. The purpose of this study was to describe sleep duration and its relationship with BMI and body composition. Forty-nine individuals, with a BMI of 36.6 ± 9.8 kg/m2, regained 26.4 ± 17.8% o...

Introduction: Inactivity and weight regain are serious problems post-bariatric surgery. Nearly half of waking time is spent at work, representing an opportunity to accumulate physical activity and help avoid weight regain. Purpose: The purpose of this study is to evaluate potential differences in physical activity and sedentary time by employmen...

ᅟChronic inactivity and weight regain are serious health concerns following bariatric surgery. Neighborhood walkability is associated with higher physical activity and lower obesity rates in normal weight populations. PurposeExplore the influence of neighborhood walkability on physical activity and sedentarism among long-term post-bariatric surgery...

Chronic sedentarism and weight re-gain are both serious concerns following bariatric surgery. Pre-surgery, employment rates are lower compared to the normal weight population. Participation in daily activity is affected by multiple factors such as age, sex, high socioeconomic status and white collar occupations, which are also inversely associated...

Eccentric ergometer training (EET) is increasingly being proposed as a therapeutic strategy to improve skeletal muscle strength in various cardiorespiratory diseases, due to the principle that lengthening muscle actions lead to high force-generating capacity at low cardiopulmonary load. One clinical population that may particularly benefit from thi...

Objectives: Inexpensive activity monitors have recently gained popularity with the general public. Researchers have evaluated these consumer-based monitors in laboratory-conditions. Given the current wide-spread consumer use of these devices, it is important to ensure users are attaining accurate information compared to previously validated measur...

Chronic inactivity and weight re-gain are both serious health concerns following bariatric surgery. Neighborhood walkability is associated with physical activity in normal weight populations. PURPOSE: To explore the influence of neighborhood walkability on the daytime sedentary and physical activity habits of bariatric patients long-term post-surge...

To measure sedentary behaviors and physical activity using accelerometry in participants who have undergone bariatric surgery 8.87 ± 3.78 years earlier and to compare these results with established guidelines. Participants' weight and height were measured, an ActivPAL™3 accelerometer and sleeping journal were used to determine day sedentary time, t...

Purpose: Sedentary time, or prolonged sitting/lying time, is an emerging risk factor for severe obesity, independent of physical activity (PA). The purpose of this study was to characterize ambulatory PA as well as sitting/lying time using accelerometry before and after bariatric surgery. Material and methods: Seventeen participants (58.5% female)...

Physical Activity Levels and Aerobic Capacity in Bariatric Patients 10 Years Following Weight Loss Surgery

Physical activity (PA) is an important adjunct to bariatric surgery in the treatment of severe obesity; however, patient PA levels prior to and in the short-term following surgery are usually low. Scarce data exist describing PA and sedentary behaviours in the long term following surgery. The objectives were to describe PA and sitting time in baria...

A new measurement tool, the automated software CoreScan, for the GE Lunar iDXA, has been validated for measuring visceral adipose tissue (VAT) against computed tomography in normal weight populations. However, no study has evaluated the precision of CoreScan in measuring VAT among severely obese patients. The purpose of the study is to evaluate the...

Bariatric surgery is currently the preferred treatment for severe obesity, but little is known about sleep habits and daytime sedentary behaviors for the individuals that undergo this procedure. Excessive daytime sedentary behaviour has been independently associated with weight gain and obesity, and may be related to post-surgical weight regain. PU...

An active lifestyle with low levels of sedentary time have both been independently associated with the prevention of weight regain in formerly obese individuals. Most guidelines advocate that patients should strive to lead physically active lives and reduce time spent sitting and lying after bariatric surgery. However, little is known about the acc...

Bariatric surgery patients often exhibit low levels of physical activity (PA), despite the presumed importance of PA as an adjunct to surgery for successful weight loss. Little is known regarding the associations of PA and sedentary behaviors to weight loss outcomes in the long term following surgery. The objective of the study was to assess the as...

No study has evaluated the precision of the GE Lunar iDXATM (GE Healthcare) in measuring bone mineral density (BMD) among severely obese patients. The purpose of the study was to evaluate the precision of the GE Lunar iDXATM for assessing BMD, including the lumbar spine L1-L4, L2-L4, the total hip, femoral neck, and total body in a severely obese p...

To evaluate the precision of the iDXA for total body composition and fat distribution measurements in severely obese patients. Sixty-five severely obese participants with a mean age of 46 ± 11years, BMI of 49 ± 6 kg/m2, and a mean body mass of 137.3 ± 20.9 kg took part in this investigation. Two consecutive iDXA scans with repositioning of the tota...

Corresponding author's email: norah.macmillan@mail.mcgill.ca RATIONALE: Restraints to ventilation and skeletal muscle weakness in patients with severe COPD often limits their tolerance to traditional forms of concentric (CON) endurance training. Eccentric (ECC) cycle training has been proposed to be more effective than CON training at increasing mu...

Abstract for conference

Chronic hemiparetic stroke individuals are at a higher risk of falling. This may be due to balance impairments, cardiovascular deconditioning, and muscle weakness associated with stroke effects. Postural instability associated with fatigue would likely be attained more rapidly for stroke individuals than for healthy individuals. To determine the ef...
