- NCT05688956
- Lead Sponsor
- University College Dublin
- Brief Summary
To explore the effectiveness of a 12-week resistance exercise programme plus or minus an oral nutritional supplement on the nutritional status of community-dwelling older adults who receive home care and are at risk of sarcopenia.
- Detailed Description
The aim of this study is to investigate the effectiveness of consuming a whey-based protein ONS enriched with leucine and vitamin D, in conjunction with an online resistance-based exercise programme, versus the effectiveness of an online exercise programme alone, for twelve weeks, in a cohort of older adults who are at risk of sarcopenia and who require supportive home care.
The primary outcome will be functional and nutritional status measured using the Timed get Up and Go (TUG) test and the full form of the mini-nutritional assessment (MNA-FF). The secondary outcomes include feasibility of implementation, defined by recruitment, retention and adherence rates, measures of body composition, muscle strength and quality of life.
The groups will be as follows: (i) whey protein ONS enriched with leucine and vitamin D plus an online exercise programme or (ii) an online exercise programme alone.
The exercise programme will be comprised of two sessions per week for 12-weeks and will be delivered using the UCD Zoom platform. The exercise programme will include strength movements that are intended to build muscle mass and improve physical function. The exercise programme will involve four phases split over the 12-week intervention: phase 1 (2 weeks), phase 2 (3 weeks), phase 3 (3 weeks) and phase 4 (4 weeks).
The ONS is a high protein, leucine and vitamin D enriched drink. Participants randomised to the ONS group will be asked to consume the drink twice a day for 12 weeks.

Group Intervention Description (i) ONS + Exercise group Dietary advice This group will consume whey protein ONS enriched with leucine and vitamin D, twice a day for 12 weeks. The optimal time to consume the ONS on non-exercise days will be based on each participants 24-hour dietary recall. On exercise days, participants will be asked to consume the ONS after breakfast and after the exercise class. Participants will participate in a resistance-based exercise programme twice a week for 12 weeks which will be carried out over Zoom. Standard dietary advice to increase intake of protein, leucine and vitamin D using available literature designed for those at risk of malnutrition will be provided to this group by the research nutritionist. (ii) Exercise-alone group Dietary advice Participants will participate in a resistance-based exercise programme twice a week for 12 weeks which will be carried out over Zoom. Standard dietary advice to increase intake of protein, leucine and vitamin D using available literature designed for those at risk of malnutrition will be provided to this group by the research nutritionist. The participants will not be provided with a placebo ONS. (i) ONS + Exercise group Resistance Exercise programme This group will consume whey protein ONS enriched with leucine and vitamin D, twice a day for 12 weeks.

- Primary Outcome Measures
Name Time Method Change from baseline functional status at 12 weeks 12 weeks Timed Get Up \& Go test will be used to assess physical performance as advised by the EWGSOP2 to test for sarcopenia.
Change from baseline nutritional status at 12 weeks 12 weeks The nutritional status of participants will be assessed using the full form of the mini-nutritional assessment-full form (MNA-FF). 24 - 30 points indicates normal nutrition status; 17 to 23.5 points indicates at risk of malnutrition \& less than 17 points indicates malnutrition.
- Secondary Outcome Measures
Name Time Method Muscle strength Values at baseline will be compared to values recorded at 12 and at 24 weeks Handgrip strength will be used to assess upper-body strength
Muscle mass Values at baseline will be compared to values recorded at 12 and at 24 weeks Muscle mass will be assessed using Bioelectrical Impedance Analysis
Adherence 12 weeks Attendance at the resistance exercise classes + consumption of the protein supplement
Five Times Sit-To-Stand test Values at baseline will be compared to values recorded at 12 and at 24 weeks Five Times Sit-To-Stand test will be used to assess lower extremity strength
4 m Gait Speed test Values at baseline will be compared to values recorded at 12 and at 24 weeks 4 m Gait Speed test will be used to assess physical performance as advised by the EWGSOP2 to test for sarcopenia
Change in self-reported quality of life Values at baseline will be compared to values recorded at 12 and at 24 weeks The Health Related Quality of Life 12-Item Short Form Survey (SF-12v2) will be used to assess participants quality of life. Score ranges from 0 - 100, higher score indicates higher quality of life.
Change in risk of depression Values at baseline will be compared to values recorded at 12 and at 24 weeks The Geriatric Depression Score-15 item questionnaire will be used to screen for risk of depression in the participants. Score of 0-5 is normal \& score greater than 5 suggests risk of depression.
Change in functional status Values at baseline will be compared to values recorded at 12 and at 24 weeks The Katz Index of Independence in Activities of Daily Living will be used to assess functional status. Score of 6 indicates full function, 4 indicates moderate impairment, and 2 or less indicates severe functional impairment.
Change in baseline nutritional status at week 24 24 weeks The nutritional status of participants will assessed using the full form of the mini-nutritional assessment-full form (MNA-FF). 24 - 30 points indicates normal nutrition status, 17 to 23.5 points indicates at risk of malnutrition \& less than 17 points indicates malnutrition.
Change from baseline functional status at 24 weeks 24 weeks Timed Get Up \& Go test will be used to assess physical performance as advised by the EWGSOP2 to test for sarcopenia.
Retention Up to 24 weeks The number of participants retained at the end of the study
Recruitment Up to 24 weeks The number of participants recruited divided by the number of eligible participants.
