简要总结
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.

盲法说明
The concealment of allocation will be conducted by a researcher not involved in the clinical procedures of the intervention using the method of opaque, sealed, and consecutively numbered envelopes. The random sequence and allocation concealment allow for the control of selection bias.
For enhanced bias control, the data analysis will be performed by a researcher blinded to the intervention groups.

结局指标
主要结局
Treatment Adherence
时间窗: Post-Intervention (Week 6): Final evaluation after 6 weeks.
In the context of this study, treatment adherence refers to the extent to which participants follow the prescribed physical exercise regimen. This variable is operationalized as the completion of at least 70% of the scheduled exercise sessions. A participant will be considered "adherent" if they complete at least 70% of the scheduled exercise sessions, according to the data obtained through the described measurement methods. This figure is calculated by dividing the number of completed sessions by the total number of scheduled sessions and multiplying the result by 100.
Systolic and Diastolic Blood Pressure
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
Pressure in the arteries during and between heartbeats. (mmHg)
Body Mass Index
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
The Body Mass Index (BMI) is a metric used to assess the relationship between an individual's weight and height, thereby estimating their weight category, which can range from underweight to obesity. It is calculated by dividing a person's weight in kilograms by the square of their height in meters. The formula is: BMI = weight (kg) / \[height (m)\]\^2 The unit of measurement for BMI is kg/m² (kilograms per square meter).
VO2 peak
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
Peak oxygen consumption (VO2peak) refers to the maximum amount of oxygen the body can utilize during intense exercise. It is measured in milliliters of oxygen consumed per kilogram of body weight per minute (ml/kg/min). Using the number of steps in the 2-minute walk test, VO2peak will be estimated. The equation to estimate peak oxygen consumption is: VO2 (mL⋅kg-1⋅min-1) = 13.341 + 0.138 × total steps - (0.183 × BMI).
Fasting Glucose
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
Blood glucose level after a fasting period. (mg/dL)
Cholesterol
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
Blood cholesterol refers to the total amount of cholesterol present in the bloodstream. (mg/dL)
Triglycerides
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
Blood triglycerides are a type of fat (lipid) found in the bloodstream. (mg/dL)
Handgrip strength
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
Handgrip Dynamometry: Measurement of handgrip strength. (kgf)
Global Rating Scale
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
The Global Rating Scale (GRS) will be applied as an instrument for evaluating the patient's perception of changes experienced in their health status, functionality, or symptoms. The methodology for implementing the GRS will involve asking patients to provide a rating of their current health status compared to an established reference point, which, in our case, will be the beginning of the study. The GRS will be presented in two formats: Numeric: Offering a range that can vary, for example, from -7 (much worse) to +7 (much better), allowing for a gradable assessment of changes. Descriptive: Providing qualitative terms such as "much worse," "no change," or "much better," facilitating patients' expression of their perception of change in a more narrative manner. The "unit" of measurement for the GRS is the position on the numeric scale or the descriptive term that best represents the patient's perception of change.
Mean Arterial Pressure (MAP)
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
Measure of the average pressure in a person's arteries during one cardiac cycle. MAP=Diastolic Blood Pressure + 1/3 (Systolic Blood Pressure-Diastolic Blood Pressure). mmHg
Heart Rate
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
Number of heartbeats per minute. (bpm)
Lean Mass
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
Lean mass, also known as lean body mass, refers to the portion of the body that is not composed of fat. It includes muscles, bones, internal organs, skin, body water, and other fat-free tissues. The unit of measurement for lean mass is (%).
Fat Mass
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
Fat mass refers to the total amount of fat tissue in the body. The unit of measurement for lean mass is (%).
Cardiorespiratory fitness
时间窗: Pre-Intervention: Initial assessment before starting the training program. Post-Intervention (Week 6): Final evaluation after 6 weeks.
2-Minute Step Test (2MST): is a functional fitness assessment used to evaluate an individual's cardiorespiratory fitness. During this test, the participant is instructed to march in place for two minutes, lifting their knees to a height midway between the patella (kneecap) and the iliac crest (hip bone). The goal is to count the number of times the right knee reaches the target height within the two-minute period. The primary unit of measurement for the 2-Minute Step Test is the number of steps, specifically the number of times the right knee reaches the required height within the two-minute duration.
