Brief summary
Longitudinal prospective multicenter study with intervention and control groups and a two-year follow up. Participants will include 40 sedentary adults 50 years old or older with HIV infection and 20 sedentary adults 50 years old or older without HIV infection. Our main objective is to analyze the effects of a personalized multicomponent exercise program (strength, resistance, balance, and flexibility) (PMEP) on physical function, frailty, and quality of life among older adults with HIV. As secondary objectives, we are going to analyze the effects of a PMEP on body composition, muscle function biomarkers, immunological biomarkers, microbiome, and adherence to PMEP in real conditions under intense, moderate nonexistent monitoring.
Detailed description
PMEPs will be designed according to the specific characteristics of each participant and their grade of usual physical activity. Physical activity will be registered on physical activity bracelets to get objective information in order to evaluate adherence to the PMEP. A global evaluation of the patients will be made at baseline and months 3, 6, and 12. At each evaluation, samples of blood, stool, urine, and saliva will be taken, and a phone meeting will be scheduled at month 24.
Interventions
Physical activity expert will design for each participant a personalized exercise program according to baseline situation and previous physical activity. Both will be measured prior to initiation of activity program. Each participant is free to perform physical activity program at his house, outdoor or in a gym as long as it fulfills the prespecified requirements. Exercise programs will be acquired a more personalized shape during the course of the study. In order to motivate participants, personal motivational messages will be sent each week through mail contact or using WhatsApp Social Media. Physical activity will be registered in an activity wristband delivered to each participant at baseline evaluation.
Analyze the effects of PMEP on body composition in each evaluation using an impedance threshold device
Quadriceps muscle ultrasound (US) of the rectus femoris measured in each evaluation in order to analyze the effects of PMEP Visceral fat will be analyzed in each visit

Masking description
Masking will not be performed due to the necessity of active supervision and follow up of the activity program
Intervention model description
Multicentric prospective longitudinal clinical study with intervention with a control group (Non HIV patients) and a group wih HIV
Eligibility
Inclusion criteria
* People living with HIV (Control group not included) * Age equal or older to 50 years old at initiation of study * Sedentary individuals: \< 150 minutes per week of moderate physical activity. * Absence of physical limitations which impede the performance of a light or moderate physical activity program
Exclusion criteria
\* Individuals with one or more of the following diseases: * Acute myocardial infarction (in the previous 3-6 months) or unstable angina * Uncontrolled cardiac arrythmias * Severe aortic stenosis * Acute Pericarditis/ Endocarditis * Poorly controlled high blood pressure (\> 180/100 mmHg) * Acute thromboembolic disease * Acute severe cardiac heart failure
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Effects of a personalized multicomponent exercise program (strength, resistance, balance, and flexibility) (PMEP) | 12 months | To analyze the effects of a personalized multicomponent exercise program (strength, resistance, balance, and flexibility) (PMEP) on physical function among older adults with HIV. Physical function will be assessed using Short Physical Performance Battery (SPPB or Guralnik test) will be measured in each evaluation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Comparison of PMEP effects between HIV and non HIV participants of the same age | 12 months | In order to measure if the impact of PEMP in older adults with HIV is higher than in non HIV participants, 20 individuals of similar age have been included without HIV infection. Impact of PMEP will be measured analyzing frailty which will be assessed using Fried phenotype in each visit |
| Assesment of body composition evolution after implementation of PMEP using a segmental multi frequency body composition analyser though electrical impedance | 12 months | Electrical bioimpedance measurement wil be performed in baseline evaluation and 3, 6 and 12 months after initiation of PMEP. The device used is Tanita MC-780 S MA analyzing BMI in kg/m\^2 |
| Effects of PMEP in muscular and immunological biomarkers and in microbiome | 12 months | At each evaluation (baseline, 3, 6 and 12 months), samples of blood, stool, urine, and saliva will be taken. Immunosenescence and chronic inflammation in HIV are considered at the present moment one of the main drivers of non AIDS comorbidities. Several studies have shown solid conclusions positioning physical activity as a clear intervention which reduces chronic inflammation in individuals without HIV as well as in people living with HIV. |
| Evaluation of PMEP adherence | 12 months | PMEP adherence rate will be assessed in real life conditions with different supervision levels (narrow, medium and no supervision at all) |
