Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study will require participants to attend two laboratorial sessions to complete the following:
• The Physical activity stage of change questionnaire
• The International physical activity questionnaire-short form (IPAQ-SF)
• A bespoke process evaluation questionnaire (at post-testing only)
• The Barriers to Being Active Quiz
• 24-hr food record
• Stature and body mass
• Cardiometabolic health outcomes; resting blood pressure and fasted blood glucose
• Cardiorespiratory fitness: Graded exercise test to assess peak oxygen consumption (VO2peak).
• Maximal leg power: Vertical jump.

After completing these questionnaires and tests, participants will be provided with an e-bike (a pedal-powered bicycle with electric motor assistance) to ride on an indoor circuit for 10-min, to familiarise with the equipment. Participants will then be asked to rank their likelihood of using an e-bike from a visual analogue scale (VAS) where zero will indicate ‘very unlikely’ and ten will indicate ‘very likely’. Participants will then be asked to record reasons for their given VAS score. Motion during the 10-min ride will be collected using a portable motion capture system to determine balance and steering of the e-bike.

Laboratory testing will be conducted before the use of an e-bike, and after 4 weeks of using an e-bike. Participants will also be asked to use, as often as possible, an e-bike for 4 weeks before returning to the laboratory for testing. Travel data from their e-bike use will be monitored using the e-bike odometer. After this, they will return to the laboratory to repeat the tests. We expect that pre and post intervention tests will require a total of 60-min in each visit, along with 4 weeks of use of the e-bike.

Motivational Interviewing with Cognitive Behavior Therapy (MI-CBT) will be incorporated into weekly audio meeting for participants (15-20 min each) with a trained member of the research team to discuss weekly the participants goals and expectations from the exercise intervention, past experiences with physical activity, how to identify potential barriers to long-term physical activity and strategies to overcome the identified barriers. Research team will implement MI-CBT strategies including open ended questions, affirmations, reflection, and summary to guide the participants through the intervention for four weeks engaging individually with participants.
Adherence to the intervention would be through Polar Flow, with adherence to the MI-CBT intervention session attendance.

Eligibility
Key inclusion criteria
Participants eligible for the study will be apparently healthy adults (18-to less than 65 years of age).
No medical contra-indication to perform exercise, no musculoskeletal, neurological or cardiorespiratory illness. Participants who are familiarised with bicycle riding will be eligible to participate in this study. This will involve prior experience riding a bicycle. Participants should not be meeting the current guidelines for physical activity (i.e. 75 min of vigorous exercise or 150 min of moderate intensity exercise or an equivalent combination of moderate-vigorous exercise per week).
Minimum age
18 Years
Maximum age
64 Years
Sex

Key exclusion criteria
Medical contra-indication to perform exercise, musculoskeletal, neurological or cardiorespiratory illness, no prior experience using a bicycle, and meeting the current guidelines for physical activity (i.e. 75 min of vigorous exercise or 150 min of moderate intensity exercise or an equivalent combination of moderate-vigorous exercise per week).

Efficacy
Statistical methods / analysis
Data distribution will be analysed using the Shapiro-Wilks tests. If normality of distribution is confirmed, parametric tests will be used.
For levels of physical activity before and after the intervention (primary outcome), data from the current physical activity participation questionnaire will be utilised to describe change in physical activity from the intervention.
Correlations between changes in health, cardiorespiratory and musculoskeletal health in relation to the physical activity performed during the intervention will be analysed. Correlations coefficients were ranked as poor (0–0.5), moderate (0.5–0.75), good (0.75–0.90), and excellent (> 0.9) (Dancey & Reidy, 2004). Statistical differences were deemed significant when p<0.05.
