Background: In-task affective responses to moderate-intensity continuous exercise training (MICT) have been shown to predict future physical activity behavior. However, limited research has investigated whether this affect-behavior relationship is similar for high-intensity interval training (HIIT) and whether it holds true over the longer term. This study aims to determine (1) if in-task affect during 2 weeks of supervised MICT and HIIT predicted changes to unsupervised moderate-to-vigorous physical activity (MVPA) behavior 12 months post-intervention and (2) if this predictive relationship was moderated by exercise type (MICT vs.

Purpose: Multiple sclerosis (MS) is a neurological disease that is chronic, progressive characterized by symptoms of relapsing fatigue and pain. Despite evidence supporting the use of physical activity (PA) for MS symptom management, low rates of PA participation are observed. Previous research suggests exercise-related cognitive errors (ECEs) can deter and decrease PA participation.

Background: Mobile health (mHealth) prompts (e.g., text messaging, push notifications) are a commonly used technique within behaviour change interventions to prompt or cue a specific behaviour.

Background: Low-carbohydrate ketogenic diets are a viable method to lose weight that have regained popularity in recent years. Technology in the form of mobile health (mHealth) apps allows for scalable and remote delivery of such dietary interventions and are increasingly being used by the general population without direct medical supervision. However, it is currently unknown which factors related to app use and user behavior are associated with successful weight loss.

To better understand exercise-related cognitive errors (ECEs) from a dual processing perspective, the purpose of this study was to examine their relationship to two automatic exercise processes. It was hypothesized that ECEs would account for more variance than automatic processes in predicting intentions, that ECEs would interact with automatic processes to predict intentions, and that exercise schema would distinguish between different levels of ECEs. Adults (N = 136, Mage = 29 years, 42.

Objective: The aim of this study was to determine whether a Mediterranean-style, ketogenic diet mobile health application (app) with breath acetone biofeedback is superior to a calorie-restricted, low-fat diet app in promoting weight loss.

Methods: Participants (n = 155) with overweight/obesity (mean [SD]: age 41 [11] years, BMI = 34 [5] kg/m , 71% female) were randomized to one of the interventions delivered entirely via app. Participants received a wireless scale and were instructed to take daily weight measurements.

Improving diet and physical activity (PA) can reduce the risk of developing type 2 diabetes (T2D); however, long-term diet and PA adherence is poor. To impact population-level T2D risk, scalable interventions facilitating behavior change adherence are needed. Text messaging interventions supplementing behavior change interventions can positively influence health behaviors including diet and PA.

Background: Multiple sclerosis (MS) impairs muscular function and limits individuals' ability to perform everyday activities requiring mobility. People with MS frequently exhibit mobility problems (ie, slower walking speed, shorter strides). General exercise training (eg, resistance, aerobic) provides modest physiological and walking mobility benefits.

More than 350 million people are living with prediabetes. Preventing type 2 diabetes (T2D) progression can reduce morbidity, mortality and health-care costs. Interventions can support people with diet and physical activity behaviour changes; however, many interventions are university-based, posing barriers (e.

The purpose of this secondary analysis study was to examine the affective and social cognitive responses to low-volume high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) over a progressive two-week supervised intervention for individuals at risk of type 2 diabetes. Ninety-nine adults that were low-active and overweight were randomized into one of two exercise conditions and had affective and social cognitive measures assessed before, during, and after intervention. Increases over time in post-exercise enjoyment, attitudes towards exercise, and intentions to exercise were noted for both HIIT and MICT conditions (ps <.

Purpose: Self-regulatory efficacy (SRE) is a psychological resource necessary for cardiac rehabilitation (CR) exercise adoption and maintenance. A 2008 review of self-efficacy for CR exercise identified the need for more high-quality research on SRE. The present review had 4 purposes: (a) to review the characteristics of empirical SRE and CR exercise research since 2008; (b) to examine the quality of SRE measurement; (c) to determine whether varying quality of SRE measurement moderated the relationship between SRE, exercise, and CR social cognitions; and (d) to make recommendations for better measurement for future research.

Background: Obesity and being overweight are major contributing factors for many diseases. Calorie restricted diets often fail to result in sustained long-term weight loss. Very low-carbohydrate, high-fat ketogenic diets have been suggested to have superior metabolic and weight loss effects.

Objectives: Diabetes rates in the British Columbia (BC) interior are rising more rapidly compared with the rest of Canada, whereas diabetes service provision is limited within this region. The purposes of this article were: 1) to identify characteristics of diabetes service delivery; and 2) to co-develop community‒university diabetes research projects to address service barriers and gaps in the BC southern interior across urban, rural and Indigenous populations.

Methods: A 3-step approach was used.

Background: A number of mobile health (mHealth) apps exist that focus specifically on promoting exercise behavior. To increase user engagement, prompts, such as text messages, emails, or push notifications, are often used. To date, little research has been done to understand whether, and for how long, these prompts influence exercise behavior.

The Daily Physical Activity (DPA) policy in British Columbia requires elementary schools to help students achieve 30 min of physical activity during instructional and noninstructional time on school days. The purpose of this study was to determine how elementary teachers implement the DPA policy, and examine differences in children's light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) at school, based on how the teacher implemented the DPA policy during the school day (provision of DPA during instructional time or only noninstructional time). In this observational mixed-methods study, 12 teachers were interviewed on their implementation approaches.

Purpose: High-intensity interval training (HIIT) may lead to superior cardiometabolic improvements when compared with moderate-intensity continuous training (MICT). However, adherence to HIIT requires examination. The purpose of this pilot study was to examine moderate-to-vigorous physical activity (MVPA) adherence 24 wk after a brief counseling intervention combined with either HIIT or MICT.

Background: Cardiac rehabilitation (CR) exercise therapy facilitates patient recovery and better health following a cardiovascular event. However, post-CR adherence to self-managed (SM)-exercise is suboptimal. Part of this problem may be participants' view of CR staff as mainly responsible for help and program structure.

Exercise-related cognitive errors reflect biased processing of exercise-relevant information. The purpose of this study was to examine whether differences existed between individuals reporting low and high exercise-related cognitive errors on information processed about a relevant exercise decision-making situation. In all, 138 adults completed an online questionnaire.

This study examined psychological differences between individuals (1) with varying perceptions of their exercise adherence pattern and (2) who do and do not make exercise-related cognitive errors. A total of 364 adults completed an exercise pattern and cognitive errors questionnaire. Individuals perceiving themselves as consistent exercisers reported more adaptive social cognitive outcomes (e.
