Brief summary
The benefits of multicomponent physical exercise (MPE) in the mental and physical health of older adults are widely accepted. However, during Covid19 pandemic, some face-to-face programs for physical exercise were canceled. The situation was particularly complex in nursing homes (NHs) because residents were often confined to their floors and many leisure activities were canceled. Online physical exercise sessions increased their popularity during the pandemic. However, there is no evidence that online physical exercise sessions are an effective alternative to face-to-face sessions for older people living in NHs. The current project aims to assess a synchronous online MPE program's feasibility, acceptability, and effects. With this aim, first a synchronous online MPE intervention was designed and then a multicenter randomized controlled trial with 3 branches was developed: face-to-face MPE, online MPE and control. Participants in the control group will receive advice to maintain physical activity and reduce sedentary behavior. Additionally, those in the intervention groups will also participate in 24-week individualized and progressive MPE programs performed at moderate intensity that will be focused on strength, balance, and endurance. MPE will be performed through supervised sessions (2 per week). One of the intervention groups will be supervised face-to-face whereas the other will be supervised synchronously online. Study assessments will be conducted at baseline, at the end of the 24-week intervention, and after 24-week follow-up. The primary outcomes of the study will be changes in mental and physical health. Secondary outcomes will include other parameters of mental and physical health, together with physical activity, frailty, quality of life, and biological markers. The dropout rate, the adherence, the injuries and other adverse events suffered by the participants, and technical incidences produced in the online modality will be recorded. A mixed-model ANCOVA will be performed to compare the data between intervention and control groups, considering as co-variables baseline measurements. The statistical analysis will be performed on the whole sample and separated for sex/gender. The study received ethical approval (M10\_2022\_405\_IRAZUSTA ASTIAZARAN). The results of this project will be transferred to institutions and entities involved in managing NHs to increase the opportunities for the residents to remain physically active.
Interventions
After the baseline assessments, all participants will receive individualized counseling for following physically active lifestyle and reducing sedentary behaviors. Participants will be encouraged to increase the physical activity time and intensity, and to hourly break the sedentary time while at home. The recommendations will be transmitted verbally and through written material.
This intervention will entail: Strength training of upper and lower limbs. Familiarization phase will include 2-3 exercises of 1-2 series and 8-12 repetitions per session. During the acquisition phase, 2-3 exercises of 2-3 series and 8-12 repetitions at a higher velocity. The resting time between sets will be of 1-3 minutes. Balance exercises will include proprioception, agility and weight transfer exercises. Difficulty will progressively increase by reducing the base of support, by including multidirectional displacements, walking on tiptoe or heels, body-weight transfer, dynamic exercises modifying the centre of gravity, and stressing postural muscles and by sensorial reductions. Flexibility exercises: Static stretching maintained during 20-30s carried out at the end of each session. All the sessions will be supervised online by trained physiotherapists or sports physiologists.

Masking description
The investigators in charge of doing the statistical analysis and assessing the outcome measures will be blinded to group allocation. Due to the characteristics of the study, blinding the participants and the care provider (i.e., the professional conducting the exercise sessions) to the group allocation is not possible.
Intervention model description
Each group will be assigned to control, online intervention or face-to-face intervention

|---|---|---|
| Trail Making Test (TMT) | At baseline, after 24 weeks of intervention and after 24 weeks follow-up | The TMT is a valid and widely used test to assess executive functioning. The TMT consists of two parts, part A and part B. Part A is based on number sequencing and assesses visual-perceptual abilities and participants have to draw lines to link numbers from 1 to 25 in ascending order. Part B focus on number and letter switching evaluates cognitive flexibility and consists of drawing a line to link the numbers and the letters alternatively following in ascending order (e.g. 1-A-2-B-3-C). The completion time will be registered in seconds. Lower duration indicates better performance |
| Spanish Version of the Yesavage Depression Scale | At baseline, after 24 weeks of intervention and after 24 weeks follow-up | The Yesavage Depression Scale, also known as the Geriatric Depression Scale (GDS), is a widely used self-report questionnaire designed to detect symptoms of depression in older adults. it consists 15 simple yes/no questions focusing on mood, cognition, and behavior. The scale helps assess the severity of depressive symptoms and can aid in determining the need for further evaluation or intervention. The scores range from 0 to 15. Higher values indicate more depressive symptoms. |
