Description of intervention(s) / exposure
BMM Study is a randomised, controlled 8-week intervention trial designed to examine the effect of curcumin-fortified whey protein beverage supplementation and strength training sessions on physical performance in healthy older adults aged 65-80 years living independently at retirement villages across Auckland, New Zealand.

This study will take place in retirement villages, and participants will engage in the intervention from their respective villages. Thus, there are no visits to the lab.

Enrolled participants will be assigned to any one of the three beverage groups: (a) curcumin-fortified whey protein beverage group, (b) whey protein group, or (c) placebo group.

A research team consisting of coordinating investigator and research assistants will come to the retirement village to conduct a baseline assessment of anthropometry measures and physical performance. After completing the baseline assessment, a certified personal trainer will come to the retirement village three times a week for eight weeks to conduct strength training sessions.

Strength training sessions will be about 45 mins to 1 hour long, and use medium and heavy strength resistance bands for the exercises. Exercises will include resistance band seated row, banded squats, resistance band lateral raise (to name a few) - 4 sets of 15-20 reps with medium resistance bands for weeks 1-4. The exercises will progress to resistance band bicep curl, banded front & side lateral raises, resistance band push-ups with taps, step-ups, and more – 3 sets of 10-20 reps with the heavy resistance band. Exercises will vary from week to week to add variety to the sessions. Strength training sessions will take place in groups of no more than 10 participants at the retirement village.

Participants will consume the assigned supplement under the personal trainer’s supervision and fill out a training log within 30 mins of completing every strength training session i.e., three sessions per week: a total of 24 sessions across eight weeks. Participants will receive the powdered supplement in the form of sachets that will be mixed with 250-300 ml of water.

At the end of 8 weeks, our research team will again come to the retirement village to conduct a reassessment of all baseline measures, and that would be marked as the completion of the trial.

Fortified whey protein beverage will contain 15 g of protein and 150 mg of curcumin, whey protein beverage will contain 15 g of protein and yellow food colour, and placebo beverage will contain maltodextrin and yellow food colour. All beverages will be isocaloric.

Focus Groups for assessment of qualitative measures.

Participating in focus groups is optional. Focus groups will take place at the retirement villages where the participants reside, and 5-6 individuals per beverage group would participate.

For the focus group session before the trial, the questions would be about what you think about the study, how you feel about participating in the study, what could be barriers to commitment to the study and more. For the session after the trial, the questions would be about how you found the strength training program, what you enjoyed the most, what could be done better, and more.

The session will be audio-recorded on a mobile phone and through notes on paper. The identities of the participants will be confidential.

Statistical methods / analysis
According to G*Power analysis (F tests - ANOVA: Repeated measures, within factors), for an effect of 0.5 with a power of 0.8 at an alpha level of p < 0.05 for three groups with two-time points, the estimated sample size is 12. However, due to the potential for participants drop out, we aim to recruit 20 participants per group.

SPSS will be used for statistical analysis
