The specific research aims are to compare, in PD, the effects of HIIT or CMIT on: 1) maximal exercise capacity; 2) neural and non-neural factors contributing to muscle strength, power and fatigability; 3) biomechanical measures of postural stability and gait; and 4) Clinical markers (Mini-BESTest and Unified Parkinson's Disease Rating Scale (UPDRS)). The investigators hypothesize that, HIIT will produce greater improvements in: 1) exercise capacity; 2) muscle strength, power and reduced fatigability; 3) stability and gait velocity; and 4) clinical markers.
Methods: This pilot project will involve a randomized trial of 30 individuals with PD comparing the effects of HIIT and CMIT. Training will be completed thrice weekly for 10 weeks. Participants will include men and women between 50-85 years of age, who are able to stand unsupported for 1 min, walk 18m without use of an aid, and mount a stationary bike. Participants will be randomized to either HIIT (10, 1-minute cycling intervals at 90% of peak power output, each separated by 1-min at 10% peak power output) or CMIT (30-50min cycling at 60% of peak power output). Participants will undergo the following pre- and post-training assessments: Cardiovascular testing will examine hemodynamic and efferent muscle sympathetic responses to static handgrip exercise and post-exercise circulatory occlusion; Neuromuscular testing will examine muscle activity (electromyography) during voluntary and electrically stimulated contractions of the knee extensors; Biomechanical testing will examine whole-body stability, gait, and balance patterns; and Clinical risk assessments (Mini-BESTest and UPDRS).

|Estimated Primary Completion Date :||December 1, 2019|
|Estimated Study Completion Date :||May 1, 2020|
|Experimental: High Intensity Interval Training||
Other: High Intensity Interval Training
Participants will complete exercise training 3x/week for 10 weeks. Exercise will consist of 10, 1-minute cycling intervals at 90% of peak power output, each separated by 1-min at 10% peak power output.
|Active Comparator: Continuous Moderate Intensity Training||
Other: Continuous Moderate Intensity Training
Participants will complete exercise training 3x/week for 10 weeks. Exercise will consist of 30-50 minutes of cycling at 60% peak power output.
- Maximal exercise capacity [ Time Frame: Change from baseline following 10 weeks of aerobic exercise training ]VO2 max
- Handgrip strength [ Time Frame: Change from baseline following 10 weeks of aerobic exercise training ]Maximal handgrip strength
- Blood Pressure [ Time Frame: Change from baseline following 10 weeks of aerobic exercise training ]Systolic and Diastolic Blood Pressure
- Heart Rate [ Time Frame: Change from baseline following 10 weeks of aerobic exercise training ]Cardiovascular measure
- Mini-Balance Evaluation Systems Test (Mini-BESTest) [ Time Frame: Change from baseline following 10 weeks of aerobic exercise training ]Rating scale consisting of 14 items that are each scored from 0-2, where "0" indicates the lowest level of function and "2" the highest level of function. The test has a maximum score of 28 points.
- Unified Parkinson's Disease Rating Scale (UPDRS) [ Time Frame: Change from baseline following 10 weeks of aerobic exercise training ]We will use the rating scale to examine 3 segments. 1) MENTATION, BEHAVIOR AND MOOD - 4 questions scored between "0" and "4"; 2) ACTIVITIES OF DAILY LIVING - 13 questions scored between "0" and "4"; and 3) MOTOR EXAMINATION - 14 questions scored between "0" and "4". In each case, a score of "0" indicates normal responses.
