Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All Participants will perform a light session of resistance-based exercise following a thorough warm up. The session of resistance-based exercise consists of machine-based exercises (described below) that provide a supporting surface for balance when performing the exercise. All participants will also undertake pre-testing and measures of body composition one week prior to the trial to ensure the amount of weight lifted during the exercise session can be safely and confidently performed.

This study is a randomised cross over trial, meaning that participants will be randomised into two groups. Either group 1 (fish oil) or group 2 (coconut oil/placebo). After a washout period of 4 weeks, participants will swap groups so that at the end of the trial each participant will have completed a period of fish oil supplementation and a period of coconut oil supplementation. Participants will be randomly allocated to one of the following two experimental:
Group 1: Fish Oil supplementation
Participants allocated to this group will be required to consume 4 fish oil capsules (6g/d containing 2.16g of EPA and 1.42g of DHA) PUFA daily for 4 weeks. We recommend that participants space their consumption of the fish oil evenly throughout the day and advise participants to take two fish oil capsules in the morning and two capsules in the evening.

Side effects: The side effects of fish oil supplementation are rare but may include heartburn, nausea, loose stools and rash. Consumption of fish oil supplements can also lead a fishy after taste that may be unpleasant. The fish oil supplement we have chosen for this study is designed to minimise fishy after taste. If you have a known allergy or hypersensitivity to fish or other fish products (including shellfish), you should be not consuming fish oil supplements.

Exercise session
The duration of the exercise session, including adequate warm-ups, will be ~60 minutes. The following exercises have been selected as they are low risk and easy for untrained individuals to complete. The following exercises have been selected based on previous established protocols as they are low risk and the most basic exercises for untrained individuals to complete. The following exercises have been used in previous studies thus deemed safe for older adults to perform.
Acute Resistance Exercise Session:
1. Leg Press - 3x10 @ RPE 7-8
2. Leg Extensions - 2 x 12 @ RPE 7-8
3. Machine Chest Press - 3 x 10 @ RPE 7-8
4. Dumbbell Side Lateral Raises - 3 x 12 @ RPE 7-8

Resistance exercise will take place at the end of the supplementation periods
To monitor adherence to the intervention participants will be asked to return capsules not consumed. Analysis of blood will also determine adherence to the intervention

Treatment: Other
Comparator / control treatment
Group 2: Placebo (Coconut Oil)
Participants allocated to this this group will be required to consume 6 coconut oil capsules (6g) daily for 4 weeks. We recommend that participants space their consumption of the coconut oil evenly throughout the day and advise participants to take 3 capsules in the morning and 3 capsules in the evening.

Side effects: There are no known side effects of coconut oil
Control group
Placebo

Outcomes
