RESUMEN
BACKGROUND: Interventions to support physical activity participation among individuals with spinal cord injury (SCI) are required given this population's low levels of physical activity and extensive barriers to quality physical activity experiences. OBJECTIVE: This study aimed to develop a mobile health intervention, called SCI Step Together, to improve the quantity and quality of physical activity among individuals with SCI who walk. METHODS: Our overarching methodological framework was the Person-Based approach. This included the following 4 steps: conduct primary and secondary research (step 1); design intervention objectives and features (step 2a); conduct behavioral analysis and theory (step 2b); create a logic model (step 3); and complete the SCI Step Together program content and integrated knowledge translation (IKT; step 4), which occurred throughout development. The partnership approach was informed by the SCI IKT Guiding Principles. Three end users pilot-tested the app and participated in the interviews. RESULTS: Step 1 identified issues to be addressed when designing intervention objectives and features (step 2a) and features were mapped onto the Behavior Change Wheel (step 2b) to determine the behavior change techniques (eg, action planning) to be included in the app. The logic model linked the mechanisms of action to self-determination theory (steps 2/3). Interviews with end users generated recommendations for the technology (eg, comparing physical activity levels with guidelines), trial (eg, emailing participants' worksheets), and intervention content (eg, removing graded tasks; step 4). CONCLUSIONS: Using the SCI IKT Guiding Principles to guide partner engagement and involvement ensured that design partners had shared decision-making power in intervention development. Equal decision-making power maximizes the meaningfulness of the app for end users. Future research will include testing the acceptability, feasibility, and engagement of the program. Partners will be involved throughout the research process. TRIAL REGISTRATION: ClinicalTrials.gov: NCT05063617; https://clinicaltrials.gov/ct2/show/NCT05063617.
RESUMEN
El presente artículo describe el proceso sistemático seguido para desarrollar unas directrices científicas de ejercicio para personas con lesión medular, así como sus resultados. Para mejorar la condición física, las personas adultas con lesión medular deben realizar al menos 20 minutos de ejercicio aeróbico de intensidad moderada-vigorosa, dos veces por semana, combinados con tres series de ejercicios de fuerza de intensidad moderada-vigorosa por cada grupo muscular con funcionalidad, dos veces por semana. Para mejorar la salud cardiometabólica, se sugiere que las personas adultas con lesión medular realicen al menos 30 minutos de ejercicio aeróbico de intensidad moderada-vigorosa tres veces por semana. Dado que la falta de información sobre el tipo y la cantidad de actividad física necesaria para obtener beneficios saludables es una barrera importante para las personas con lesión medular, este conocimiento puede ser de gran relevancia para la promoción de estilos de vida activos entre este colectivo
The present paper describes the systematic process adopted to develop scientific exercise guidelines for adults with spinal cord injury and its results. To improve fitness, adults with spinal cord injury should engage in at least 20 minutes of moderate-to-vigorous intensity aerobic exercise twice a week, combined with three sets of strength-training exercises for each major functioning muscle group, at a moderate to vigorous intensity, twice a week. To improve cardiometabolic health, adults with spinal cord injury are suggested to engage in at least 30 minutes of moderate-to-vigorous intensity aerobic exercise three times a week. Since lack of information on the type and the amount of physical activity needed to obtain health benefits is an important barrier for people with spinal cord injury, this knowledge could be of great relevance in order to promote physically active lifestyles in this population

OBJECTIVE: The purpose of this study was to apply Ajzen's theory of planned behavior (TPB) and a measure of past physical activity behavior to predict first-year students' physical activity intentions and behavior. PARTICIPANTS AND METHODS: First-year university students (N = 212) completed measures of TPB variables and past physical activity at the start of the 2006 fall semester and a measure of physical activity 8 weeks later. RESULTS: The TPB variables explained 37% of the variance in intentions, increasing to 39% with the addition of past behavior. Logistic regression showed that past behavior predicted whether students met Health Canada standards for being physically active (4 > or =sessions of moderate/vigorous physical activity per week). CONCLUSIONS: Findings are consistent with other research showing that the TPB offers a good prediction of physical activity intentions but falls short of predicting behavior.

OBJECTIVE AND PARTICIPANTS: The authors assessed the stability of diet and physical activity and their relationship to weight changes in first-year university women. METHODS: They collected anthropometric and body composition data from 101 resident women at the beginning of their first year of college and again at 12 months. The authors obtained physical activity and dietary logs 4 times throughout the year. RESULTS: Caloric intake decreased over 12 months in all participants (p = .01). There was little change in physical activity in participants who lost weight (p = .73, d = .18). Those who gained weight experienced a trend toward decreased physical activity (p = .13, d = .38). A significant Time X Group interaction on physical activity (p = .04) suggests that physical activity patterns differed substantially between individuals who gained weight and those who lost weight. CONCLUSIONS: Reduction in physical activity appears to be the defining characteristic in freshman weight gain.
