Inclusion criteria

  • Parkinson's Disease Hoehn \& Yahr Stages 1-3
  • Able to walk 50 meters unassisted
  • Able to understand and communicate in English

Exclusion criteria

Exclusion Criteria:

  • Uncontrolled cardiovascular or other neuromuscular disease that prevent participation in a training program
  • Any systemic inflammatory or conditions such as rheumatoid arthritis, or other serious concomitant medical illness
  • Unresolved injury or surgery to the upper or lower limbs that prevents weight training.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

    10% Velocity-Loss Threshold Resistance Training

    Participants will receive velocity-based resistance training at 10% velocity-loss threshold, twice per week for at least 24 sessions for up to 12 weeks.

    Behavioral: 10% Velocity-Loss Threshold Resistance Training

  • Experimental
    30% Velocity-Loss Threshold Resistance Training

Interventions

  • Behavioral10% Velocity-Loss Threshold Resistance Training

    Participants will receive a total of twenty-four 45-minutes in-person training sessions at 10% velocity-loss threshold, twice per week using three sets of eight repetitions per set. During training participants will be allowed 1-minute rests between sets. Exercises will include four upper-body exercises and 2 lower-body exercises.

What researchers measure

Primary outcomes

  1. Change in neuromuscular performance as measured by 1-repetition maximum (1RM)

    Maximal load that can be lifted in one repetition (1RM) will be assessed in both leg press and chest press exercises. The loads on the testing equipment will be increased across 5 to 7 testing repetitions. The persons 1RM will be the highest load the person can move through the range of motion of the exercise. There are no minimum or maximum scores for this test. The higher the 1RM the stronger the person is. The unit of measurement is kilograms.

    Time frame: Baseline, 12 weeks

  2. Change in neuromuscular performance as measured by Watts

    This test measures the power a person can produce at maximal speed using loads of 20%, 40%, 60%, 80%, and 90% of 1RM for the chest press and leg press. Power shows how fast a person can do work. There are no minimum or maximum possible values. Higher values indicate better neuromuscular performance. Unit of measure is Watts.

    Time frame: Baseline, 12 weeks

Secondary outcomes

  1. Change in the Speed of the Ten-Meter Walk Test.

    The ten-meter walk test will be used to assess gait velocity. The participants will be asked to walk at usual walking speed and as quickly as possible in a straight line on a 10-meter (m) course marked at 0, 2, 8 and 10 m. On verbal command, participants will start on the 0-m mark and stop when the 10-m mark is crossed. The total time to ambulate from the 2-m mark to the 8-m mark (6 m total) will be timed to the hundredth of a second. Two trials will be performed at each speed, and the average will be documented in meters per second. One-minute recoveries will be provided between trials.

    Time frame: Baseline, 12 weeks

  2. Change in Time for the Five Times Sit-to-Stand Test.

    The five-time sit-to-stand test will be used to assess functional lower body strength. The participant will sit with arms folded across the chest and the back against the chair. On a verbal command, the participant will stand up and sit down five times as quickly as possible. Timing begins at the word go and ends when the buttocks touch the chair after the fifth repetition. One practice and two testing trials will be performed. Time will be measured in seconds.

    Time frame: Baseline, 12 weeks

  3. Change in the time required to complete the timed Up-and-Go Test.

    Upon verbal cue, participants will stand up, walk around a cone placed three meters from the front edge of the chair and then returns to a seated position as quickly as possible. Time is measured in seconds.

    Time frame: Baseline, 12 weeks

  4. Change in Distance of the Seated Medicine Ball Throw.

    Upper body power will be assessed using the Seated Medicine Ball Throw test. Participants will sit in an armless chair with their back against the chair back and throw a 6-pound medicine ball from the chest as far as possible at an approximate 45-degree angle. Participants will complete three recorded test attempts. The distance thrown in meters will be measured. There are no minimum or maximum possible values. Greater throwing distances indicate better upper body power.

    Time frame: Baseline, 12 weeks

  5. Change in Muscle Thickness using Ultrasound.

    Muscle thickness will be assessed using B-mode ultrasonography. Three longitudinal-view images will be obtained for each muscle assessed. Muscle thickness will be measured by drawing a perpendicular line from the superficial aponeurosis to the deep aponeurosis at the thickest region of the muscle. Assessments will be performed on selected thigh and upper arm muscles. Muscle thickness is measured in centimeters (cm). Higher values indicate greater muscle thickness.

    Time frame: Baseline, 12 weeks

  6. Change in Muscle Quality using Ultrasound.

    Muscle quality will be measured using a gray scale. Grayscale values range from 0 to 255 units, where lower values (darker pixels) indicate greater muscle tissue content and higher values (lighter pixels) indicate greater intramuscular fat. The muscle to be tested will be the thigh muscles and the back of your arm. Lower grayscale values indicate better muscle quality.

    Time frame: Baseline, 12 weeks

Timeline

2 registry updates since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Sep 2026 (actual). Primary completion is estimated for Dec 2026, 3 months after the start.

Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's planned 3 months is below that.

Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
