Clinical Trial 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.

Intervention

Behavioral:
• Advice to increase physical activity and reduce sedentary behavior
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.
• Online Physical Exercise
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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Trail Making Test (TMT)	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	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Primary	Spanish Version of the Yesavage Depression Scale	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.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Primary	30-seconds Chair Sit to Stand test	A test to measure muscle function of the lower limbs. Starting in a seated position, participants will be instructed to perform as many full sit-to-stand cycles as they could in a 30-second timeframe with the number of cycles considered the score for this test. Higher scores indicate better performance.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Secondary	MoCA (Montreal Cognitive Assessment)	MoCA test will be used to evaluate the cognitive function of participants. The MoCA was designed as a rapid screening instrument for mild cognitive dysfunction (63). It assesses different cognitive domains: attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation. Time to administer the MoCA is approximately 10 minutes. The total possible score ranged from 0 to 30. Higher scores indicate better performance.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Secondary	Wechsler Adult Intelligence Scale III (WAIS-III)	The WAIS-III is a test battery that has long been the gold standard for the evaluation of cognitive abilities (69). Specifically, we only use the digit span to evaluate working memory (70). Participants will be asked to recall a list of numbers in the order that they will be given (forward or backwards). The test is finished when for the same item the participant fails two attempts. A total number of correct answers will be registered for each condition. Higher values indicate better performance.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Secondary	EuroQol-5 dimensions (EQ-5D-5L)	European Quality of Life-5 Dimensions (EQ-5D) questionnaire. Participants will self-rate their health on a vertical visual analogue scale (score range: 0-100), where the endpoints are labeled 'The worst health you can imagine' and 'The best health you can imagine'. Higher values indicate better quality of life.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Secondary	The Spanish adaptation of the Basic Psychological Needs in Exercise Scale (BPNES) (Moreno et al., 2008)	The BPNES will be used to evaluate the satisfaction of the needs perceived by the participants (73). This questionnaire includes 12 items distributed in three dimensions (autonomy, competence and the other four items measure the relationship). The score ranges from 12 to 60. Higher values indicates a greater fulfillment of basic needs in physical exercise.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Secondary	Zung's Anxiety Self-Assessment Scale (Hernández-Pozo, et al., 2008)	The Zung Anxiety Scale is a self-report questionnaire to measure the severity of anxiety symptoms in individuals. It consists of 20 questions related to various aspects of anxiety, such as physical symptoms, cognitive aspects, and emotional manifestations. Respondents rate each item based on how frequently they experience each symptom. The scale provides a quantitative assessment of anxiety levels, helping professionals to identify individuals experiencing significant anxiety symptoms and determine appropriate interventions.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Secondary	Satisfaction with Life Scale	It is a 5-question scale with Likert-type answers of 5 categories that examines de global grade of satisfaction with life. Possible answers go from absolutely untrue (1) to absolutely true (5). A score of 5 to 25 points can be obtained. Higher values indicate better satisfaction with life. The score ranges from 5 to 35. Higher values indicate greater satisfaction.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Secondary	Short Physical Performance Battery (SPPB)	The SPPB consists of three tasks that evaluate the lower extremities' function: balance, walking speed and sit-to-stand 5 times from a chair. In each task 0 to 4 points can be scored, to obtain a total score between 0 and 12 points. Higher values indicate better function.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Secondary	The Biceps Curl Test	This requires people to repeatedly lift a 5 lb (2.27 kg) weight (for women) or an 8 lb (3.63 kg) weight (for men) for 30 seconds. The number of lifts is recorded. This reflects upper body strength. Higher values indicate better performance.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Secondary	The 2-minute Walk Test (2-MWT)	2-MWT is an adaptation of 6-MWT. The test measured distance in meters walked in 2 minutes and reflects aerobic endurance. The original version of the Senior Fitness Test required people to walk on a rectangular course but more recent versions use a straight line. Higher values indicate better performance.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
Secondary	The 8 Feet Up-and-Go test	The test measures the time the subject needs to stand from a chair, walk 8 feet (2,5 meters), turn around, get back to the chair, and sit. The longer the time to complete the test, the worse the performance. Leaning on the thighs or the chair is allowed to stand. Lower time indicates better performance.	At baseline, after 24 weeks of intervention and after 24 weeks follow-up
