High-intensity strength training for people with Parkinson’s disease to test safety and feasibility (HiSTEP-PD pilot trial)

Twice-weekly high-intensity progressive resistance training sessions are delivered over 8 weeks in a gym setting for community-dwelling people with Parkinson’s disease. Each session will be 1hr in length and is provided on a one-to-one basis, with a participant paired with a Masters-level student trainer (physiotherapy, osteopathy, or exercise physiology) who has completed a structured train-the-trainer workshop and competency process. All sessions occur under direct on-site supervision from qualified allied health clinical staff. Training intensity will be monitored using rating of perceived exertion (RPE), with working sets typically targeting RPE 7–8/10, alongside structured programming (generally 2–3 sets of 6–8 repetitions with 2–3 minutes rest). Load prescription is informed by 3-repetition maximum (3RM) testing for key exercises (e.g., leg press, chest press) at baseline and post-intervention, with loads progressed conservatively based on technique, symptoms, and safety. Attendance and adherence will be recorded at every session using structured trainer logs documenting session completion, loads, RPE, and any symptoms. Prior to each session, participants are screened for fatigue, soreness, and symptom changes, and any adverse events are documented and managed according to study procedures. Exercises target major muscle groups using machine-based and/or free-weight movements tailored to individual capacity and may include leg press, chest press, knee extension/flexion, rowing or pull-down variations, hip hinge movements, and hip abduction. Sessions will include a light aerobic and mobility warm-up, a progressive resistance training block, and a cool-down involving stretching or breathing exercises.
