"Changing Behaviour towards Aerobic and Strength Exercise: Results of a randomised, phase I study determining the safety, feasibility, and consumer-evaluation of an online exercise program in persons w"

INTRODUCTION: Many people with MS do not meet the recommended exercise guidelines to elicit health benefits. Programmes combining exercise prescription and behaviour change coaching lead to optimal outcomes. This study aimed to determine the feasibility, safety and participant evaluation of an exercise intervention, based on recent exercise guidelines and principles of behaviour change, delivered online to persons with MS. METHODS: Seventy-two participants (age: 43.3 ± 13.3 years; mean ± SD) with mild to moderate MS were stratified according to previous exercise behaviour, and block-randomised into one of three groups: Control (CON; n=24), General Exerciser, (GE; n=24), and Advanced Exercisers, (AE; n=24). GE and AE received a four-month online-supervised exercise program including aerobic, resistance, balance, and flexibility training based on behaviour change theory. Participants completed questionnaires at baseline, four months, five months and eleven month. Process (e.g., recruitment), resources (e.g., monetary cost), management (e.g., staff time), and scientific (i.e., safety, outcomes, and participant evaluation) feasibility were assessed. RESULTS: Of 198 potential participants, 143 met the eligibility criteria (72%) and 72 participants were randomised. Fifty-three participants completed the intervention (74% immediate retention), and 44 participants were retained at the six-month follow-up (61%). Personnel time was 369 hours, and the total per participant cost for the study is AUD $1036.20, including personnel costs. Adherence rate was 60% (GE), and 83% (AE) and self-reported online compliance was 73% (GE) and 38% (AE) of the prescribed exercise sessions. When considering safety (e.g., number of participants experiencing a change in MS symptoms) there were no differences in safety outcomes when comparing GE (n=9), AE (n=10) and control (n=10) participants. CONCLUSION: We conclude that it is feasible, safe, and efficacious to deliver a remote exercise program with updated exercise guidelines and embedded with behaviour intervention to persons with mild-to-moderate MS. Future research should focus on determining the feasibility and acceptability of exercise prescription combined with behaviour changes to meet the recent guidelines at a wider scale across other MS populations, and to consider the feasibility of similar exercise programme delivery across neurological populations.

"Health-Related Quality of Life Associated with Fatigue, Physical Activity and Pacing in Adults with Chronic Conditions"

INTRODUCTION: Fatigue and inactivity are linked to decreased health-related quality of life (HRQoL) in adults with chronic conditions. A multidimensional approach to activity pacing targeting physical, psychological, and social factors holds promise for improving HRQoL through promoting physical activity engagement and alleviating fatigue. A transdiagnostic approach to fatigue in adults with chronic conditions is crucial, especially when underlying causes are unknown. Such approaches offer a comprehensive understanding of fatigues multidimensionality, valuable for researchers and clinicians. This study aimed to examine (1) associations between HRQoL and indices of fatigue and pacing in adults with chronic conditions, including perceived fatigue, engagement in pacing, perceived risk of overactivity, physical activity (self-reported & device-based), self-regulation of physical activity, and (2) if these associations are different for the subscales physical, social, emotional, and functional well-being. METHODS: Survey and ActiGraph (7 days) data of 66 adults with chronic conditions, experiencing fatigue, were collected. Multivariable linear mixed model analyses were performed. First, HRQoL was the dependent variable, and one of the six indices of fatigue and pacing factors was the independent variable together with confounders: pacing groups, gender, age, body mass index (BMI), duration of condition, and years of fatigue management advice. Second, interaction effects with the HRQoL domains (physical, social, functional, and emotional well-being) were added to the models. RESULTS: HRQoL was significantly associated with fatigue(B=-7.82; p=<.001), engagement in pacing(B=-.23; p=.006), self-regulation of physical activity(B=0.11; p=.013), and self-reported physical activity(B=1.32; p=.046), when corrected for confounders. Significant interaction effects were found in the models with fatigue, engagement in pacing, perceived risk of overactivity, and self-reported and device-based physical activity. CONCLUSION: Reduced fatigue is associated with enhanced HRQoL, while corrected for confounders, stressing the significance of effective fatigue management. Higher levels of self-regulatory behaviour in physical activity, corrected for confounders, and increased physical activity are linked to enhanced HRQoL, emphasising the benefits of appropriate physical activity behaviours. Lower levels of fatigue, more engagement in pacing and higher levels of physical activity have a greater impact on the physical subscale of HRQoL compared to the other subscales. Higher levels of perceived risk of overactivity and physical activity have a greater impact on the social subscale of HRQoL. The overall findings provide insights into the relationships between fatigue, pacing, self-regulation, physical activity, and their associations with HRQoL and well-being aspects underscoring the importance of a multidimensional approach to fatigue management.

"Effects of a multicomponent exercise intervention on cardiometabolic risk factors in children and young adults with CP: a cross-over trial"

INTRODUCTION: Adults with cerebral palsy (CP) have a higher risk of cardiometabolic diseases compared to the general population, but it is unknown whether this risk is elevated already in childhood and young adulthood. In addition, the evidence on the effects of exercise on cardiometabolic risk in young people with CP is limited. Therefore, we investigated the effects of a multicomponent exercise intervention on cardiometabolic risk factors in children and young adults with CP and compared this risk to typically developing (TD) controls. METHODS: The EXECP study included 13 males and 5 females, aged 9–22, with CP and 17 age- and sex-matched TD controls. The participants in the CP group were measured at baseline, after a 3-month control period and after the 3-month EXECP intervention. TD participants were measured twice during the control period, without participating in the intervention. The intervention consisted of supervised, progressive, and individualized strength, walking, and flexibility training 2–3 times/week, along with treadmill walking at home for 10 min/day with a focus on stepping. Body weight, whole-body fat percentage, and skeletal muscle mass index (kg/m2) were measured using bioimpedance. Systolic and diastolic blood pressure and pulse wave velocity were measured in a supine position from the left arm with an oscillometric device. Plasma LDL and HDL cholesterol, triglyceride, and glucose levels were assessed from fasting blood samples. Between-group differences in the first measurement were analyzed with independent samples t-tests and Mann-Whitney U tests. Within-group changes in cardiometabolic risk factors were analyzed using age- and sex-adjusted linear mixed-effects models, in which the participant was included as a random effect. RESULTS: Participants with CP had 1.0 kg/m2 lower skeletal muscle mass index (p=0.040) and tended to have 0.4 m/s higher pulse wave velocity (p=0.062) compared to TD controls. During the control period, body weight increased by 1.9 and 0.9 kg in the CP and TD groups, respectively (p≤0.05). In addition, pulse wave velocity decreased (β=-0.44, SE=0.16), and whole-body fat percentage (β=1.22, SE=0.72), skeletal muscle mass index (β=0.13, SE=0.07), and blood glucose (β=0.18, SE=0.10) tended to increase in the CP group. During the intervention, no statistically significant changes were observed in any cardiometabolic risk factor in the CP group. CONCLUSION: Children and young adults with CP did not differ from their TD peers for most cardiometabolic risk factors. Still, lower skeletal muscle mass index may predispose them to functional limitations and higher pulse wave velocity to elevated cardiovascular disease risk. The three-month exercise intervention focusing on strength training and gait quality was not successful in lowering cardiometabolic risk in children and young adults with CP. Longer duration and greater volume and intensity of aerobic exercise may be needed.
