Brief Summary:
The researchers are investigating whether adding mobile technology to a home-based exercise counselling program makes it easier for youth to begin and maintain regular exercise Participants who joins the study will receive exercise counselling from an exercise specialist but half of all participants will receive mobile technology - a fitness watch - that links to a mobile phone App The mobile App allows the exercise specialist to provide personalized feedback throughout the program via the fitness watch The investigators are interested to know whether the fitness watch and mobile App will make it easier for youth to achieve their exercise goals Both groups will be compared to an active control group who will receive no exercise program
Detailed Description:
Purpose
The investigators aim to undertake an experimental trial using exercise training in adolescents evaluating a theoretical model where mHealth technology allowing biometric informed feedback and coaching is incorporated into a structured home-based exercise and physical activity PA intervention The overall objective is to have an evidence-based exercise and PA intervention ready to evaluate in a future randomised controlled trial RCT
Hypothesis
It is hypothesized that this approach will increase both habitual PA and adherence to structured exercise of the appropriate intensity to promote improvements in cardiorespiratory fitness and vascular function
Justification
Current physical activity guidelines suggest adolescents should accumulate at least 60 minutes of moderate to vigorous physical activity MVPA per day Yet globally more than 80 of adolescents fail to achieve the recommended level of daily MVPA and less than 25 of Canadian adolescents are sufficiently physically active Adolescence is a time when sedentary habits predominantly manifest Sedentary time increases by approximately 100 minutesday between the ages 12 and 16 years and there is a disproportionate number of inactive adolescent girls 82 compared to boys 71 Clearly current strategies to encourage appropriate levels of physical activity in adolescence are inadequate
It is important to note that the current MVPA guidelines lack the intensity associated with the enhancement of cardiorespiratory fitness in youth 85-90 of heart rate maximumFurther the extant data show that habitual physical activity is not related or at best weakly related to direct laboratory measures of cardiorespiratory fitness in youth
If we aspire to improve cardiorespiratory or vascular health in our younger population we need to find ways to engage adolescents in sufficient exercise ie 40-60 minutes 3 to 4 times per week at 85-90 of heart rate maximum
Objectives
Primary Objective
1 Determine the number of sedentary adolescents that are eligible to participate the proportion of these who would be willing to take part in this trial and their characteristics and the number of participants retained at 6-months
Secondary Objectives
1 Adherence to the exercise training
2 Estimate precision of potential outcome measures required for sample size estimations for the definitive RCT
3 Intervention acceptability
Research Design
The study is a randomised controlled intervention whereby participants will complete pre-randomisation baseline testing T1 before a 3-month supported PA and exercise intervention is completed Immediately post-intervention T2 and 6-months after the intervention is completed
Statistical Analysis
The proportion of eligible patients who consent to participate in the pilot will be presented along with the proportions in each intervention group completing each follow up assessment and the reasons for withdrawal Descriptive characteristics and outcome data will be summarized overall and by intervention group as mean standard deviation for normally distributed continuous variables median interquartile range for non-normally distributed continuous variables and number percentage for categorical variables
Interview data will be analysed using thematic analysis which will allow the research team to discuss emerging themes and help the research team to explore the barriers and facilitators to the intervention and refine the theoretical model assessing which elements of the intervention are most effective for participants As this is a pilot study there will be no formal comparisons between groups in the intervention
