Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All participants will undertake individualised high intensity aerobic exercise 3 times per week for 6 to 12 months. The exercise will consist of one or a combination of the following:
• high intensity continuous aerobic exercise for 30 min at 75 to 85% HRmax or equivalent;
• high intensity interval training involving 4 x 4 min at 85 to 95% HRmax or equivalent, with 3 min active recovery between intervals;
• All exercise will include 5 to 10 mins of aerobic exercise warm-up and 5 mins of cool-down.

High intensity aerobic exercise will be delivered via different modalities (e.g., fast walking/jogging/running on a treadmill or overground, cycling, elliptical cross-training, rowing, stair climbing) and delivered at home and/or in the community (e.g., local park or gym) based on individual preferences and suitability. Participants may choose one or a combination of different aerobic exercises and change their exercise modality/delivery for the duration of the trial as long as they maintain compliance to the high intensity training prescription (i.e., remain in their high intensity training zone). Participants’ high intensity training prescription will be calculated using results from their graded exercise test as per routine practice for clinical exercise specialists. Compliance with exercise intensity during exercise (achieving and maintaining high intensity targets) will be via HR sensor (Polar H9 or equivalent) and perceived exertion using a Rating of Perceived Exertion scale regularly during their exercise.

A physiotherapist or exercise physiologist will visit participants in their homes and/or community at the start of the trial to set up their individualised, high intensity aerobic exercise program. The physiotherapist/exercise physiologist will supervise the participants, monitor their exercise responses, and progress the exercise until they meet their target training prescription and are safe to exercise independently. They will be provided with written and/or pictorial instructions for their exercise. Another visit will be performed at midway (month 3) to ensure participants are exercising appropriately. Participants may receive up to four home visits during the intervention period.

Participants will be remotely supervised via weekly phone/video calls for month 1, fortnightly for months 2 and 3, then monthly for months 4 to 6. A physiotherapist or exercise physiologist will also monitor participants’ adherence and progress with the aerobic exercise program using cloud-based applications (e.g., University of Sydney OneDrive, Polar app) shared between the physiotherapist/exercise physiologist and each participant. Participants will be asked to complete an exercise diary (digital or paper) documenting the number, duration, and intensity of exercise sessions completed.

Participants will also be provided with tailored health coaching by a physiotherapist or exercise physiologist during the phone/video calls, which incorporates behaviour change techniques to facilitate self-management and adherence to exercise. Behavioural change techniques may include education on the benefits of exercise in the management of PD, identifying and addressing barriers to exercise, goal setting, action planning, providing individualised feedback, reinforcement of behavioural progress, and facilitating self-monitoring of behaviour and outcomes.

Participant supervision and health coaching will be graded, i.e., frequent supervision and coaching at the start of the intervention which are gradually withdrawn as participants become familiar with exercise and develop self-management skills. During follow-up (month 7 to 12), participants will be asked to continue their high intensity aerobic exercise program using their most recently prescribed exercise plan from the end of the intervention period (month 6). Participants will not receive any health monitoring and coaching during follow-up.

Quantitative outcomes will be explored descriptively using means (SD) or median (IQR) based on data distribution of continuous outcomes, and n (%) for discrete outcomes. Visual inspection of Total Body PET/CT will also be performed, along with parametric statistical analysis of quantitative parameters (standardised uptake value ratio (SUVR) and pharmacokinetic modelling parameters).

Qualitative data will be explored through inductive thematic analysis of the interview data. The interview data will also be used to help with interpretation of the quantitative results.

Summary
Brief summary
Parkinson's disease (PD) is the second most common neurodegenerative condition globally and its prevalence is increasing exponentially due to ageing and industrialisation. There is no cure but there is preliminary evidence to suggest high-intensity aerobic exercise may help slow down PD progression. To benefit, people with PD need to perform regular, high intensity aerobic exercise for the long term.

The primary aim of this study is to examine the feasibility, acceptability, and sustainability of a pragmatic, individualised, high intensity aerobic exercise program. Secondary aims are to quantify effects of high intensity aerobic exercise on clinical, physiological, and neuroimaging outcomes, including potential disease modifying effects. People with PD will perform high intensity aerobic exercise 3 times per week for 6 to 12 months. The type (e.g., continuous and/or interval training, e.g., fast walking/jogging/running, elliptical cross-training, rowing, stairs climbing) and location (e.g., home, gym, local park) of exercise will be tailored to meet individual needs and preferences. Participants will also receive health coaching via regular phone/video calls to support them to exercise. At the end of the study, participants will be interviewed to explore their experiences of their program.
