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.
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.

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

Effects of a personalized multicomponent exercise program (strength, resistance, balance, and flexibility) (PMEP)
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
Time frame: 12 months
Effects of a personalized multicomponent exercise program (strength, resistance, balance, and flexibility) (PMEP)
To analyze the effects of a personalized multicomponent exercise program (strength, resistance, balance, and flexibility) (PMEP) on frailty among older adults with HIV. Frailty will be assessed using Fried phenotype in each visit
Time frame: 12 months
Effects of a personalized multicomponent exercise program (strength, resistance, balance, and flexibility) (PMEP)
To analyze the effects of a personalized multicomponent exercise program (strength, resistance, balance, and flexibility) (PMEP) on quality of life among older adults with HIV. Quality of life will be assessed using World Health Organization Quality of Life HIV instrument (WHOQOL-HIV-BREF)
Time frame: 12 months
Comparison of PMEP effects between HIV and non HIV participants of the same age
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
Time frame: 12 months
Comparison of PMEP effects between HIV and non HIV participants of the same age
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 using the Short Physical Performance Battery" (SPPB or Guralnik test) which will be measured in each evaluation
Time frame: 12 months
Comparison of PMEP effects between HIV and non HIV participants of the same age
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 body composition (BMI) in kg/m\^2 which will be measured in each evaluation in order to assess changes throughout study period
Time frame: 12 months
Comparison of PMEP effects between HIV and non HIV participants of the same age
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 with Rectus femoris in cm measurements of both legs and visceral fat measurements in cm will be performed using ultrasound in each evaluation in order to see evolution in these parameters
Time frame: 12 months
Assesment of body composition evolution after implementation of PMEP using a segmental multi frequency body composition analyser though electrical impedance
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
Time frame: 12 months
Effects of PMEP in muscular and immunological biomarkers and in microbiome
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.
Time frame: 12 months
Evaluation of PMEP adherence
PMEP adherence rate will be assessed in real life conditions with different supervision levels (narrow, medium and no supervision at all)
Time frame: 12 months
