Bovine milk – a nutritional intervention for acute exercise recovery in older adults
Traditionally, resistance training has been performed by younger athletes and active individuals to improve sporting or physical performance, but recently, a greater importance has been placed on participating in resistance exercise throughout the entire lifespan to improve health and quality of life. Specifically, older adults are now actively encouraged to engage in resistance training exercises to improve muscle mass, muscular strength, body composition, metabolic health, and ability to perform daily tasks.
Intense physical exercise can cause structural and functional damage to the muscle, leading to increased inflammation, and a range of consequences such as pain, swelling and importantly a reduction in muscle function. Considering that these negative effects could hinder the ability of an older adult to complete usual daily activities, identifying nutritional interventions which may reduce the magnitude of these effects, or expedite recovery, is therefore of great importance to this population.
The aim of this project is therefore to investigate if bovine milk can lessen the effects of, and expedite recovery from resistance training induced muscle damage in older adults.

Successful applicants will be selected by the researcher.
This opportunity closes on 31st August 2022.
What will I be asked to do?
Participants would be required to attend the laboratory on five occasions. The first visit would involve maximal strength testing of the legs, and some familiarisation of tasks they will be asked to perform in the following visits.
For visits two through to five, participants would attend the laboratory on four consecutive days, at roughly the same time of day, to perform resistance exercise and perform tasks that will help us to establish their level of recovery.
You will be given this information sheet and briefed on the full study procedures at which point you will be invited to ask any questions or raise any concerns. Your participation will then depend on the satisfactory completion of a health history questionnaire.
You will then have your height and weight taken and be familiarized with the exercise equipment that will be used during the study.
Dependent of the results of your isometric leg strength test, we will allocate you to one of three experimental groups; whole milk, skimmed milk, or control.
This first visit should take no longer than 45 minutes to complete. You will then be required to attend the laboratory on a further 4 occasions.
On your second visit, we will ask you to complete a 24-hour dietary recall. You will then perform a series of measures to assess your level of muscle function and damage; these will serve as your baseline results.
Once you have completed the exercise session, we will ask you to repeat some of the baseline measures.
Once you have completed these measures, we will ask you to consume 500 mL of your assigned beverage before leaving the laboratory. We will then provide you with a further 500 mL of your beverage to take away with you to be consumed throughout the remainder of the day.
Visit 3 and 4
Your third, fourth and fifth visit will be repeating the baselines measures you completed in visit 2.
You will return to the lab approximately 24, 48 and 72 hours after visit 2 and to repeat the baseline measures only.
During your last visit we will ask you a few questions surrounding your attitudes and knowledge towards resistance training, exercise recovery, exercise recovery strategies, and how you found consuming your supplement.
These visits will take approximately 30 - 45 minutes to complete.
When and where?
Where: Newcastle University Sports Centre
When: A date and time that suits you.
You will be asked to attend on five occasions, with the last four visits taking place on consecutive days
Will I get anything for taking part?
Taxis to the Sports Centre can be organised and will be funded by the research group.
Each participant will be entered in to a prize draw for a chance to win a £20 voucher as a thank you for your participation.
