The study needs male participants aged between 45-60, lean or overweight, sedentary or active and in good health.
During the study, carried out jointly by the University of Auckland’s Human Nutrition Unit and Liggins Institute, participants will need to have several different types of body scans, including a DeXa scan – that measures muscle, bone and fat content compared to the normal population.
People taking part will also need to have a muscle CT scan, and an ultrasound scan that can detect fat infiltration into muscle. Participants will also complete a muscle function test normally done by professional athletes to assess muscle strength.
During the final part of the study, an IV infusion of metabolic tracer will be administrated to participants for several hours. They will be given one of five different dairy products to consume.
Muscle and blood samples will be taken afterwards to detect positive changes in blood amino acid levels and muscle metabolism.
Participants will need to visit the study team on three separate occasions at the Liggins Institute in Grafton and the Millenium Institute in Mairangi Bay to complete the study.
A small gratuity will be offered for the time taken to participate in the study and to cover the travel costs. All participants will receive a copy of their results on request following the completion of the research.
This study was designed by research staff at the Human Nutrition Unit and the Liggins Institute.
All information that participants provide will remain strictly confidential and no material that could personally identify any participant will be used in any reports on this research.
