Brief Summary:
The focus of this pilot study is to evaluate the feasibility of utilizing an evidenced-based high intensity interval training program (HIIT) to improve physical function in patients with knee osteoarthritis (OA).

Condition or disease Intervention/treatment Phase
Knee Osteoarthritis Behavioral: High intensity interval training (HIIT) Not Applicable

Detailed Description:
All participants will be assigned to the single-arm of the study in which all participants will receive 12 weeks of HIIT, delivered twice per week. The primary outcome will examine the feasibility and acceptability of the 12 week HIIT program in patients with knee OA symptoms ranging from mild to severe. The investigators will determine adherence to and tolerability of HIIT, acceptability, and recruitment and retention rates during the 12 week program. Additional outcomes will include physical function, knee OA symptomatic burden (pain), static standing balance, isometric knee extensor and flexor strength, cardiorespiratory fitness, and body composition.

Arm Intervention/treatment
Experimental: Intervention
Intervention consists of High Intensity Interval Training (HIIT) session which is af 3-5 minute warm up, followed by 10 repetitions of 1 minute bouts at individualized training intensity with 1 minute rest periods.
Behavioral: High intensity interval training (HIIT)
Each training session for High Intensity Interval Training will consist of a 3-5 minute warm-up, followed by 10 repetitions of 1-minute bouts at individualized training intensity with 1-minute rest periods.




Primary Outcome Measures :
  1. Percent of Potential Participants Screened for the Study Who Are Enrolled [ Time Frame: Baseline ]
    Number of participants screened and enrolled divided by the total number of participants screened

  2. Percentage of Enrolled Participants Retained at the End of the Study [ Time Frame: Study completion (12 weeks) ]
    Number of participants who completed the study (baseline through 12 week assessments) divided by the total number of enrolled participants with baseline assessments


Secondary Outcome Measures :
  1. Average Number of Training Sessions Completed Per Week [ Time Frame: Weekly measures for 12 consecutive weeks ]
    Up to 2 training sessions were possible each week over the 12 week intervention

  2. Total Number of Training Sessions Completed [ Time Frame: 12 weeks ]
    Total number of training sessions completed out of up to 24 sessions (2 per week over 12 weeks)

  3. Total Number of Training Weeks Completed [ Time Frame: 12 weeks ]
    Total number of training weeks (up to 12 weeks possible)

  4. Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Total Score From Baseline to 12 Weeks [ Time Frame: Baseline,12 weeks ]
    The WOMAC, a measure of lower extremity pain (5 items), stiffness (2 items), and function (17 items), will be used to measure overall symptomatic burden of knee osteoarthritis (OA). Each item is scored from 0-4 (none, slight, moderate, severe, and extreme). Items are added to calculate a total WOMAC score ranging from 0 (no problems) to 96 (extreme problems). A higher score means a worse outcome.

  5. Change in WOMAC Pain Subscale From Baseline to 12 Weeks [ Time Frame: Baseline,12 weeks ]
    The WOMAC pain subscale contains 5 items about knee pain. Each item is scored from 0-4 (none, slight, moderate, severe, and extreme). Items are added to calculate a WOMAC pain score ranging from 0 (no pain) to 20 (extreme pain). A higher score means more severe pain.

  6. Change in WOMAC Function Subscale From Baseline to 12 Weeks [ Time Frame: Baseline, 12 weeks ]
    The WOMAC function subscale contains 17 items about knee function during daily activities. Each item is scored from 0-4 (none, slight, moderate, severe, and extreme). Items are added to calculate a WOMAC pain score ranging from 0 (no problems with function) to 68 (extreme problems with function). A higher score means worse function.

  7. Change in 20m Fast Paced Walk Test [ Time Frame: Baseline, 12 weeks ]
    Measure of the ability to walk quickly over short distances. Participants walk at fast pace that is timed over 2 x 10m.

  8. Change in Number of Chair Stand Repetitions Completed [ Time Frame: Baseline, 12 weeks ]
    Number of chair stand repetitions completed in 30 seconds

  9. Change in Stair Climb Test [ Time Frame: Baseline, 12 weeks ]
    Time in seconds to ascend and descend a flight of stairs

  10. Change in Timed Up and Go [ Time Frame: Baseline, 12 weeks ]
    Time in seconds to rise from a chair, walk 3 m, turn, walk back to chair, and sit down

  11. Change in Feet Together Stand [ Time Frame: Baseline, 12 weeks ]
    Feet together stand for up to 10 seconds without assistive device

  12. Change in Semi-tandem Stand [ Time Frame: Baseline, 12 weeks ]
    Heel of one foot placed to the side of the big toe of the other foot, for up to 10 seconds

  13. Change in Tandem Stand [ Time Frame: Baseline, 12 weeks ]
    One foot in front of the other, heel touching toe, for up to 10 seconds

  14. Change in One Leg Stand [ Time Frame: Baseline, 12 weeks ]
    One leg stand for up to 30 seconds

  15. Change in Cardiorespiratory Fitness [ Time Frame: Baseline, 12 weeks ]
    Measure by peak oxygen consumption (VO2peak),to identify fitness level and evaluate cardiovascular effects. Test will establish individual training intensity.

  16. Change in Whole Body Fat Mass [ Time Frame: Baseline, 12 weeks ]
    fat mass in kilograms, measured with dual energy x-ray absorptiometry (DXA)

  17. Change in Lean Body Mass [ Time Frame: Baseline, 12 weeks ]
    lean body mass in kilograms, measured with DXA

  18. Change in Visceral Fat [ Time Frame: Baseline, 12 weeks ]
    visceral fat in kilograms, measured with DXA

  19. Change in Knee Strength [ Time Frame: Baseline, 12 weeks ]
    Humac isokinetic dynamometer to measure isokinetic power and isometric strength of knee flexors extensors
