Brief Summary:
The purpose of this study was to investigate the effect of rebound exercise (mini trampoline jumping) on metabolic outcomes and quality of life in patients with Type 2 Diabetes.

Condition or disease Intervention/treatment Phase
Type 2 Diabetes Other: Rebound exercise Not Applicable

Detailed Description:
The exercise involved jumping on the mini trampoline with feet slightly apart. Participants stood on the mid portion of the trampoline bed and made repeated up-and-down bouncy movements. Each foot strike equals one step or bounce. With each landing, the mat of the trampoline underwent deformation and the springs released the energy stored in them such that the participant was made to bounce off the mat. Exercise was administered for between 10 - 15 minutes after which a 5-minute period of rest was allowed. A heart rate monitor was used to guide the intensity of the exercise in the moderate range. Each participant accumulated between 20 and 30 minutes of rebound exercise (bouncing on a mini trampoline) per session, administered three times per week for 12 weeks. All data were captured at baseline and at the end of the 12-week intervention period.

Arm Intervention/treatment
Experimental: Rebound exercise

Other: Rebound exercise
Repeated jumping on a mini trampoline was administered
Other Name: Mini trampoline rebounding

No Intervention: Control
No exercise was administered but participants continued with routine medical care

Primary Outcome Measures :
  1. Glycated hemoglobin [ Time Frame: 3 months ]
    Glycated hemoglobin was assessed using the mini-column ion-exchange chromatographic method and expressed in percentage

Secondary Outcome Measures :
  1. Fasting plasma glucose [ Time Frame: 3 months ]
    Fasting plasma glucose (in molar concentration) was measured by glucose oxidase assay using a glucose analyzer

  2. Fasting insulin [ Time Frame: 3 months ]
    Fasting insulin (in gravimetric unit) was determined using a commercially available ELISA human insulin kit

  3. High-density lipoprotein cholesterol [ Time Frame: 3 months ]
    High-density lipoprotein cholesterol (in molar concentration) was enzymatically determined using commercial kits

  4. Total cholesterol [ Time Frame: 3 months ]
    Total cholesterol (in molar concentration) was enzymatically determined using commercial kits

  5. Triglycerides [ Time Frame: 3 months ]
    Triglycerides (in molar concentration) were enzymatically determined using commercial kits

  6. Low-density lipoprotein cholesterol [ Time Frame: 3 months ]
    Low-density lipoprotein cholesterol (in molar concentration) was estimated using the Friedewald formula.

  7. Quality of life [ Time Frame: 3 months ]
    The short-form 36 health questionnaire was used to assess participants' quality of life and expressed in percentage

  8. Body mass [ Time Frame: 3 months ]
    Body mass in kilograms was determined using a calibrated weighing scale

  9. Height [ Time Frame: 3 months ]
    Height in meters was determined using a stadiometer

  10. Heart rate [ Time Frame: 3 months ]
    Heart rate was measured in beats per minute using a calibrated electronic device

  11. Respiratory rate [ Time Frame: 3 months ]
    Respiratory rate (in cycles per minute) was measured by observing and counting the number of times the chest rose in one minute

  12. Blood pressure [ Time Frame: 3 months ]
    Blood pressure in millimeters of mercury (mmHg) was measured using a calibrated electronic device

  13. Maximal oxygen consumption [ Time Frame: 3 months ]
    Maximal oxygen consumption in milliliters per kilogram per minute (ml/kg/min) was obtained from exercise stress testing

  14. Diabetes-related emotional distress as measured by the Problem Areas in Diabetes Scale [ Time Frame: 3 months ]
    Diabetes-related emotional distress was expressed in percentage

  15. Well-Being as measured by the World Health Organization-Well-Being Index [ Time Frame: 3 months ]
    Participants' well-being was expressed in percentage

  16. Treatment satisfaction as measured by the World Health Organization-Diabetes Treatment Satisfaction Questionnaire [ Time Frame: 3 months ]
    Score ranges from 0 (very dissatisfied) to 36 (very satisfied)

Other Outcome Measures:
  1. Depressive symptoms as measured by the Beck's Depression Inventory [ Time Frame: 3 months ]
    Score ranges from 0 to 63 with 0 to 13 being minimal and 29 to 63 being severe
