Changes in Movement, Fitness, and Quality of Life in People With Parkinson's Disease After Different Exercise Programs
Sponsor: University of Texas, El Paso
Summary
Parkinson's disease (PD) is a progressive neurological condition that can affect movement, balance, endurance, and overall quality of life. Exercise is widely recognized as one of the most effective non-pharmacological treatments to help people with PD maintain function and independence. However, not all exercise programs produce the same results, and more research is needed to understand which types of exercise offer the greatest physical and physiological benefits. This study is designed to examine how different types of structured exercise programs influence motor function, cardiorespiratory fitness, and markers of overall health in individuals with Parkinson's disease. The goal is to better understand how exercise can be used to improve movement, daily activities, and general well-being, as well as how it affects the body at a physiological level. Participants will be adults diagnosed with idiopathic Parkinson's disease who are medically stable and able to safely participate in exercise. Before beginning the study, participants will complete screening procedures to ensure safety and eligibility. Eligible participants will then be assigned to one of several supervised exercise interventions conducted over a defined period. Each exercise program is designed to improve movement and function but differs in structure or training emphasis (for example, aerobic, functional, or task-specific activity). Exercise sessions will take place under the supervision of licensed physical therapist. Each session will include warm-up, exercise, and cool-down components. Intensity will be monitored using heart rate and perceived exertion to ensure safety and appropriate challenge. Participants will attend sessions multiple times per week for 8 weeks. Researchers will collect information about movement abilities, balance, walking, endurance, and daily function using standardized physical therapy assessments such as gait tests, balance measures, and questionnaires related to quality of life at baseline, after 8-weeks of intervention and once more after a 4-week follow-up. In addition, blood samples will be collected to analyze physiological responses to exercise at the same 3 testing intervals. These samples will allow investigators to measure biomarkers related to cardiovascular health, nitric oxide availability, oxidative stress, and inflammation. These biological indicators can help identify how exercise affects underlying health mechanisms that may contribute to improved function in people with Parkinson's disease. All data will be collected by trained research personnel who are experienced in working with individuals with Parkinson's disease. Participants will be monitored for safety at each session, and any adverse events will be documented and reviewed by the principal investigator and the Institutional Review Board (IRB). By comparing changes across the different exercise programs, this study aims to determine which interventions have the most meaningful impact on mobility, endurance, and quality of life, as well as which ones produce measurable physiological benefits. Results from this research may help guide physical therapists, rehabilitation professionals, and people with Parkinson's disease in choosing the most effective exercise approaches for maintaining function and promoting overall health. Ultimately, this project seeks to contribute to the growing evidence that targeted, engaging, and appropriately dosed exercise can play a key role in improving the lives of people living with Parkinson's disease. The findings may also help inform future clinical practice guidelines, community exercise programs, and long-term wellness strategies for individuals with movement disorders.

Conditions
Interventions
Guided Cycling
Participants will complete supervised cycling sessions on a stationary ergometer twice per week for eight weeks. Exercise intensity is based on each participant's lactate threshold as determined by cardiopulmonary exercise testing (CPET). Each 60-minute session includes a warm-up, cycling intervals of varying intensity, and a cool-down. Heart rate and perceived exertion are monitored continuously to ensure safety and adherence to prescribed intensity zones.
Non-Contact Boxing
Non-Contact Boxing Exercise Program Participants will engage in a structured, non-contact boxing program modeled after the Rock Steady Boxing® framework. Sessions are held twice weekly for eight weeks and include warm-up activities, agility and coordination drills, four boxing rounds using heavy and speed bags, and a circuit for balance and strength training. Each session concludes with a cool-down. All activities are supervised by licensed physical therapists trained in Parkinson's-specific exercise safety.
Traditional Physical Therapy Program (Standard of Care)
Participants in this group will receive multimodal physical therapy sessions twice per week for eight weeks. Each 60-minute session includes aerobic training (cycling or treadmill), resistance and balance exercises, gait training, and task-specific functional activities such as transfers and turning. Intensity is maintained at 60-85% of maximum heart rate, with continuous heart-rate monitoring. Sessions are led by a licensed physical therapist following standard clinical practice guidelines.
