Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention will take place at exercise clinic and exercise laboratory at University of Tasmania, Newnham campus. Attendance sheets will be used to mark attendance at every session. All the exercise sessions will be supervised by physiotherapist working under exercise physiologist.
Group 1. participants will be asked to exercise on treadmill (downhill walking) for 30 mins, twice a week for 12 weeks. The decline will start at 4% and progress to 16% till the end of training period. Participants will exercise at light to moderate intensity (RPE 10-13; assessed by Borg 6-20 RPE scale). Participants will be progressed from 5 to 20 minutes over the first 4 sessions and thereafter by time (up to 30 minutes) and gradient (4% decrements up to a maximum of 16%) when they are able to complete the prescribed session at an RPE of 10-11.
Group 2. participants will exercise on treadmill with an incline (uphill walking) for 30 mins, twice a week for 12 weeks. The incline will start at 4% and progress to 16% till the end of training period. Participants will exercise at light to moderate intensity (RPE 10-13; assessed by Borg 6-20 RPE scale). Participants will be progressed from 5 to 20 minutes over the first 4 sessions and thereafter by time (up to 30 minutes) and gradient (4% increments up to a maximum of 16%) when they are able to complete the prescribed session at an RPE of 10-11.

Minimum age
18 Years
Maximum age
70 Years
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria

• Patients with poor balance (high fall risk)

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Group allocation into either an uphill treadmill exercise group (n=16), downhill treadmill exercise (n=16) group, and flat treadmill exercise group (n=16) will be stored in sealed opaque envelopes and opened in front of the participant after baseline assessment
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
After initial recruitment in the study the participants will be randomly allocated to three groups via block randomisation with equalisation between groups every 6 or 9 participants by an independent researcher not involved in assessment or delivery of the intervention using a computer-generated sequence of numbers.
Masking / blinding

Efficacy
Statistical methods / analysis
Data will be assessed (intention-to-treat and per-protocol) through STATA statistical software (STATA SE v15). Between group differences will be analysed using a linear mixed models assessment to determine differences between groups (uphill treadmill exercise vs downhill treadmill exercise vs flat level treadmill exercise) and between time points (TEST 1 and TEST 2). If the assumptions of linear regression are not met the analysis will be conducted using mixed effects logistic regression. Potential confounders including baseline physical activity, adherence to intervention (including walking duration) will be adjusted for in data analysis.

Summary
Brief summary
This study will involve a comparison of predominately eccentric (ET) versus concentric (CT) endurance exercise. Participants in one group will perform downhill walking, participants in second group will perform uphill walking and participants in the third group will perform level treadmill walking, twice a week for 12 weeks with 2-3 days between sessions. Exercise sessions will commence at 5 minutes duration at the same comfortable walking pace and progress to 30-minutes session by the last week. Outcome measures will be assessed at baseline and after the completion of the 12-week exercise program. Exercise will assess whether downhill walking is better than uphill or level walking in glucose handling among people with type 2 Diabetes Mellitus.
