Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the experimental group will complete a 10-week progressive resistance training program. They will be taught 7 exercises: three exercises for the upper limbs, three exercises for the lower limbs and one exercise for the trunk. All exercises will be completed on weight machines in a local gymnasium and each exercise session will take approximately 60 minutes. The training program is based on the recommendations of the American College of Sports medicine and will comprise 3 sets of 12 repetitions of each exercise at a training intensity of 12RM. The weight lifted in each exercise will be increased when 3 sets of 12 repetitions of an exercise can be completed. Two-minute rest periods will be given between each exercise set. The program will be conducted twice weekly for 10 consecutive weeks. Participants will complete the program one-on-one with a physiotherapist. Adherence will be monitored using an exercise log-book.

Comparator / control treatment
Participants in the (waitlist) control group will continue with their typical daily activities, which may include leisure and sporting activities, but will not include a progressive resistance strength training. The control group will be offered the intervention after all assessments have been completed i.e. approximately 12 weeks after the intervention group.

Outcomes
Primary outcome [1] 297181 0
Muscle force generation (1 repetition maximum of leg press and chest press)
Timepoint [1] 297181 0
At baseline and 1 week after the intervention has ceased
Primary outcome [2] 297199 0
Safety
Timepoint [2] 297199 0
Adverse events will be monitored during the intervention period using exercise log-book and classified as minor/ major; expected/ unexpected; related to the intervention/ unrelated to the intervention. An example of a possible adverse event is delayed onset of muscle soreness which would be anticipated in people who are unaccustomed to exercise, but which would be expected to resolve quickly and not interfere with training.
Primary outcome [3] 297200 0
Feasibility
Timepoint [3] 297200 0
Will be measured during the intervention phase of the trial by documentation in the exercise log-books of attendance at the exercise sessions and adherence to the exercise protocol.
