Brief Summary:
This clinical trial aims to evaluate whether a 12-week multi-component exercise program (combining waltz, resistance training, and agility training) can improve the physical, psychological, and cognitive function of women aged 65 and under with dyslipidemia. Key research questions include: Does this intervention lower lipid levels (e.g., total cholesterol, triglycerides) and improve body composition (e.g., body fat percentage, lean muscle mass)? Compared to a non-exercise control group, does this intervention enhance cardiovascular health, balance, mental health, and cognitive function? Researchers will compare outcomes in the exercise intervention group and the non-exercise control group to assess the effectiveness of the program. Study Procedure: Participants will: attend supervised exercise classes three times a week for 12 weeks (approximately 90 minutes per class). The program includes: - Waltz training (basic steps and choreographed dance movements), - Resistance band exercises (targeting major muscle groups), - Agility and balance training modules. Pre- and post-intervention assessments will include: - Lipid analysis, - Body composition analysis, - Cardiovascular health and balance tests, - Standardized mental health and cognitive assessments.

| Measure | Description | Time Frame |
|---|---|---|
| Total Cholesterol (TC) Level | Total cholesterol will be measured in fasting venous blood samples (12-hour fast) using an enzymatic colorimetric method with a clinical chemistry analyzer. The result will be reported in mg/dL. Total cholesterol refers to the overall amount of cholesterol in the blood, which includes LDL-C and HDL-C. High levels are associated with increased cardiovascular risk. Blood samples will be collected at baseline and at the end of the 12-week intervention. | From baseline through the end of the 12-week intervention period |
| Triglycerides (TG) Level | Triglyceride levels will be measured from fasting venous blood samples (12-hour fast) using enzymatic assays with a clinical chemistry analyzer. The result will be reported in mg/dL. Triglycerides are a type of fat found in the blood. Elevated levels are associated with metabolic syndrome and increased risk of heart disease. Blood samples will be collected at baseline and at 12 weeks post-intervention. | From baseline through the end of the 12-week intervention period |
| High-Density Lipoprotein Cholesterol (HDL-C) Level | HDL-C will be measured from fasting venous blood samples using direct enzymatic assays. HDL-C is often referred to as "good" cholesterol because it helps remove other forms of cholesterol from the bloodstream. Low levels are a risk factor for cardiovascular disease. The result will be reported in mg/dL and assessed at baseline and after the 12-week program. | From baseline through the end of the 12-week intervention period |
| Low-Density Lipoprotein Cholesterol (LDL-C) Level | LDL-C will be measured using the Friedewald equation or direct measurement (depending on TG level) from fasting venous blood samples. LDL-C is known as "bad" cholesterol because it contributes to plaque buildup in arteries. The result will be reported in mg/dL. Blood samples will be taken at baseline and after the 12-week exercise intervention. | From baseline through the end of the 12-week intervention period |
| Measure | Description | Time Frame |
|---|---|---|
| Systolic and Diastolic Blood Pressure (SBP, DBP) | Resting systolic and diastolic blood pressure will be measured using a validated automatic digital blood pressure monitor (e.g., Omron HEM-907). Participants will be seated quietly for at least 5 minutes prior to measurement. Three readings will be taken at 1-minute intervals on the non-dominant arm, and the average of the last two will be recorded. Blood pressure is expressed in mmHg and interpreted according to international hypertension guidelines. |
| Measure | Description | Time Frame |
|---|---|---|
| Anxiety - Generalized Anxiety Disorder 7-item scale (GAD-7) | Anxiety symptoms will be evaluated using the GAD-7, a validated self-report scale assessing the frequency of anxiety-related symptoms over the past two weeks. Each item is scored from 0 ("not at all") to 3 ("nearly every day"), with a total score range of 0-21. Higher scores indicate greater anxiety severity. | From baseline through the end of the 12-week intervention period |

| From baseline through the end of the 12-week intervention period |
| Cardiorespiratory Fitness (Estimated VO₂max via 6-Minute Walk Test) | Cardiorespiratory fitness will be estimated using the 6-Minute Walk Test (6MWT), a validated submaximal field test. Participants will be instructed to walk at their fastest safe pace along a 30-meter corridor for 6 minutes. Total distance covered will be used to estimate VO₂max using validated predictive equations adjusted for age and sex. This measure reflects aerobic capacity and endurance. | From baseline through the end of the 12-week intervention period |
| Vascular Function (Pulse Wave Velocity [PWV], Ankle-Brachial Index [ABI]) | Arterial stiffness and peripheral vascular health will be assessed using a validated vascular testing device (e.g., VaSera VS-1500 or equivalent). Pulse Wave Velocity (PWV) measures the speed of arterial pulse propagation and is a marker of arterial stiffness. Ankle-Brachial Index (ABI) is calculated by dividing the systolic blood pressure at the ankle by that at the brachial artery. Both are non-invasive and widely used indicators of cardiovascular health. | From baseline through the end of the 12-week intervention period |
| Body Composition | Body composition will be assessed using a validated bioelectrical impedance analysis device (e.g., InBody 720), including body fat percentage, body fat mass, lean body mass, skeletal muscle mass, and body mass index (BMI). Participants will be measured barefoot and in light clothing after an overnight fast, following standard procedures recommended by the manufacturer. | From baseline through the end of the 12-week intervention period |
| Bone Mineral Density (BMD) | Bone mineral density will be evaluated using an ultrasound bone densitometer (e.g., Sahara Clinical Bone Sonometer), measuring the calcaneal bone (heel). The test is non-invasive, and results will be recorded as T-scores according to WHO criteria. | From baseline through the end of the 12-week intervention period |
| Static Balance | Static balance will be assessed using the single-leg stance test with eyes closed. The maximum duration (in seconds) the participant can stand unassisted on one leg without touching the ground with the lifted foot will be recorded, up to 60 seconds. Three trials will be conducted and the best result recorded. | From baseline through the end of the 12-week intervention period |
| Dynamic Balance | Dynamic balance will be measured using the Biodex Balance System SD, performing the Limits of Stability (LOS) test protocol. Participants will stand on a movable platform and shift their center of gravity to targets displayed on a screen. Scores will reflect directional control and stability performance. | From baseline through the end of the 12-week intervention period |
| Depression - Patient Health Questionnaire-9 (PHQ-9) | Depressive symptoms will be assessed using the PHQ-9, a widely used 9-item self-report measure based on DSM-IV criteria. Participants rate the frequency of symptoms over the past two weeks. Scores range from 0 to 27, with higher scores indicating more severe depression. | From baseline through the end of the 12-week intervention period |
| Mood State - Profile of Mood States (POMS) | Mood state will be measured using the Profile of Mood States (POMS), a 65-item self-report questionnaire that evaluates six mood dimensions: tension, depression, anger, vigor, fatigue, and confusion. Scores are combined to generate a total mood disturbance score. | From baseline through the end of the 12-week intervention period |
| Exercise Motivation - Behavioral Regulation in Exercise Questionnaire-3 (BREQ-3) | Exercise motivation will be measured using the BREQ-3, which evaluates different types of motivational regulation along the self-determination continuum, including intrinsic motivation, identified regulation, introjected regulation, external regulation, and amotivation. The scale uses a 5-point Likert response format. | From baseline through the end of the 12-week intervention period |
| Cognitive Function - Montreal Cognitive Assessment (MoCA) | Global cognitive function will be assessed using the MoCA, a validated screening tool for mild cognitive impairment. The MoCA evaluates attention, memory, language, executive function, visuospatial skills, and orientation. The maximum score is 30, with scores below 26 indicating possible cognitive impairment. | From baseline through the end of the 12-week intervention period |
