Summary: aim: to determine the efficacy of a personalized concurrent exercise prescription guide combined with pharmacological treatment compared to pharmacological treatment alone in controlling cardiovascular risk factors and physical capacity in adults enrolled in a cardiovascular health program. research design: this pilot randomized controlled clinical trial (rct) evaluates the efficacy of a personalized concurrent exercise prescription guide combined with pharmacological treatment versus pharmacological treatment alone. outcomes: blood pressure, fasting glucose, total cholesterol, and triglycerides, muscle strength, cardiorespiratory capacity, body composition, adherence to the exercise guide, and patient perception of intervention effects, sociodemographic and medical background, physical activity level, population: adult users of the cardiovascular health program at the external cesfam in valdivia will be recruited during regular check-up hours. detailed study information will be provided, and informed consent obtained. sample size: the sample size is 15 subjects per group, accounting for a 30% dropout rate, resulting in 39 participants. participants will be randomly assigned to experimental (eg) or control groups (cg) with a 1:1 allocation ratio. allocation concealment will be ensured with opaque, sealed envelopes. evaluations: pre- and post-intervention evaluations will be conducted in both groups. sociodemographic and medical background information will be collected through clinical record reviews. blood pressure, heart rate, glucose, triglycerides, cholesterol, adherence to the exercise guide, and patient perception of intervention effects will be measured using standardized procedures by trained kinesiologists.

scientific component, methodology, ethics, and planning research question and hypothesis research question what is the efficacy of a personalized concurrent exercise prescription guide combined with pharmacological treatment, compared to pharmacological treatment alone, in controlling cardiovascular risk factors and physical capacity in adult users of the cardiovascular health program at the external cesfam in valdivia during 2024? hypothesis h1: the efficacy of a personalized concurrent exercise prescription guide combined with pharmacological treatment is greater than pharmacological treatment alone in controlling cardiovascular risk factors (cvrf) and physical capacity in adult users of the cardiovascular health program at the external cesfam in valdivia during 2024. (group difference hypothesis) h0: the efficacy of a personalized concurrent exercise prescription guide combined with pharmacological treatment is equal to pharmacological treatment alone in controlling cvrf and physical capacity in adult users of the cardiovascular health program at the external cesfam in valdivia during 2024. (group difference hypothesis) statistical hypothesis group difference hypothesis: * h0: μa = μb * h1: μa \> μb objectives general objective to determine the efficacy of a personalized concurrent exercise prescription guide combined with pharmacological treatment, compared to pharmacological treatment alone, in controlling cardiovascular risk factors and physical capacity in adult users of the cardiovascular health program at the external cesfam in valdivia during 2024. 2.2.2 specific objectives * to describe the effects of applying a personalized concurrent exercise prescription guide on cardiovascular risk factors in adult users of the cardiovascular health program at the external cesfam in valdivia. * to describe the effects of applying a personalized concurrent exercise prescription guide on physical capacity in adult users of the cardiovascular health program at the external cesfam in valdivia. * to evaluate adherence to the personalized concurrent exercise guide and pharmacological treatment in adult users of the cardiovascular health program at the external cesfam in valdivia. * to describe the clinical significance of the interventions through the calculation of effect size and the clinical relevance perceived by the participants regarding the interventions. 2.3 methodology and procedures research design the research design corresponds to a pilot randomized controlled clinical trial (rct) with parallel groups and superiority. this design aligns with the general objective and proposed hypothesis, aiming to evaluate the efficacy of a personalized concurrent exercise prescription guide combined with pharmacological treatment, compared to pharmacological treatment alone, in controlling cardiovascular risk factors and physical capacity. the primary study variables include blood pressure, fasting glucose, total cholesterol, and triglycerides, which are standard measurements for the cardiovascular health program. secondary variables include sociodemographic and medical background, level of physical activity, muscle strength, cardiorespiratory capacity, body composition, adherence to the exercise guide, and patient perception of changes experienced due to the intervention. population the study population will consist of adult users of the cardiovascular health program (pscv) enrolled in the external cesfam in valdivia. the research team will directly invite pscv users during their regular check-up hours. research professionals will be properly identified as staff from universidad san sebastián and will provide detailed information about the research, the exercise prescription guide application, program duration, benefits, and risks. interested participants will be asked to sign informed consent. the recruitment period will last up to 1 month, extendable by another month if necessary to obtain the required sample size. sample size calculation the sample size calculation is based on recommendations from the literature for pilot studies and includes: * t-test - means: difference between two independent means, * type i error: 5%, * statistical power: 80%, * effect size (es): 0.5 according to cohen's classification. using these parameters, the recommended total sample size is fifteen subjects per group. assuming a 30% dropout rate, the total population will correspond to thirty-nine participants. after the eligibility process, participants will be randomly assigned to an experimental group (eg) and a control group (cg) using a 1:1 allocation ratio through an online randomization system. allocation concealment will be maintained using opaque, sealed, and consecutively numbered envelopes. the experimental group will receive the intervention based on the personalized exercise prescription guide plus their usual pharmacological treatment associated with the pscv, while the control group will maintain their usual pharmacological treatment associated with the pscv. information production techniques all evaluations will be performed pre- and post-intervention in both the experimental and control groups. clinical record review: the pscv's responsible physician, with prior authorization from the external cesfam's management and approval from the valdivia health service ethics committee, will review the participants' medical records, collecting information on sociodemographic and medical background: sex, age, education, time in the cardiovascular health program, medical history, medications, dosage, and duration of medication use. these variables will be used to characterize the study sample. evaluations and follow-up will be conducted by trained kinesiologists in evaluation techniques, exercise prescription, and cardiovascular risk factors, at the university of san sebastián health center in valdivia. a professional kinesiologist will measure the variables, blinded to the participant's intervention assignment. these evaluations will encompass cardiovascular variables evaluation, cardiovascular risk factor, metabolic variables, health-related physical capacity, adherence to treatment, and the global rating of change scale. 2.4 analysis of ethical implications risk-benefit analysis this study adheres to the declaration of helsinki, ensuring informed consent is obtained from all participants. the intervention will be conducted in both groups, with evaluations presenting minimal risk. users may experience post-exercise muscle fatigue, which could last up to 48 hours, mitigated through education about exercise effects. the benefits include updated knowledge about participants' health status and physical capacity, with personalized exercise shown to effectively control cardiovascular risk factors. confidentiality protection the clinical record review will be conducted at the external cesfam by the pscv responsible, and physical evaluations will be conducted at the university of san sebastián health center. participants will be assigned unique codes to preserve anonymity, with informed consent clearly stating data will not be used for purposes other than the study. collected information will be stored securely by the principal investigator for 4 years, after which it will be handed over to the cesfam. only the research team will have access to the results.
