The Wellderly study explores the communication between bone, muscle and fat and how exercise can promote healthy ageing for middle-aged and older adults.
The project is conducted at the Institute for Health and Sport (IHES) at Victoria University in collaboration with the Australian Institute for Musculoskeletal Science (AIMSS).
Participants receive information about their fitness and health and may be reimbursed with a gift card up to $100 value.
The Wellderly study
The Wellderly study will improve knowledge on how high-intensity interval training (HIIT) effects hormones involved in bone, muscle and fat interaction. There is increased evidence that bone, muscle and fat are communicating with each other, but these “communication” lines are not fully clear. It is also not clear how exercise affects the interaction between those tissues. Understanding this may result in better approaches to improving function and health as we age.
All participants will undertake fitness and health testing. They will then be randomised to either exercise training (three sessions of HIIT per week for four weeks) or control (usual activities for four weeks). Participants in the control group are offered exercise training after completing the study as a courtesy.
Participants will undergo the following assessments free of charge:
- Body composition scan (bone and lean mass) using DXA
- Blood and urine sampling
- Optional muscle and fat sampling before and after exercise
- Exercise testing
- Lifestyle questionnaires focusing on nutrition, mood and physical activity
- Measure of vascular function
- Females and males aged 45 or over (no upper age limit)
Main exclusion criteria:
- Treatment for osteoporosis as well as long-term glucocorticoid treatment
- Current smoker or quit in the past 12 months
- Hormone replacement therapy
- Body mass index (BMI) > 40 kg/m2
Please note, additional inclusion/exclusion criteria apply.
