The Effect of Water Physical Exercise Program in Thermal Water and Hydropinotherapy on Cardiovascular Health

The goal of this randomized four-arm clinical trial is to determine the effect of 16-week water physical exercise program in thermal water and hydroponotherapy on lipide profile in middle-aged and elderly people, with controlled health conditions. Participants will be randomizate into four arms: * Arm I: Control * Arm II: Water Physical Exercise Program (WPEP) in thermal water * Arm III: Hydropinotherapy with thermal water combined with bay leaf (L. nobilis) * Arm IV: WPEP in thermal water and hydropinotherapy with thermal water combined with bay leaf (L. nobilis) Primary outcome: 1. Lipid profile (cholesterol total, low-density lipoprotein cholesterol (c-LDL), high-density lipoprotein cholesterol (c-HDL), triglycerides) Secondary parameters: 2. Inflammatory biomarkers: interleukin-6 (IL-6), C-reactive protein (CRP) 3. Glucose metabolisc: fasting plasma glucose, insulin, Hemoglobin A1c (HbA1c) 4. Aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase, bilirubin, creatinine. 5. Anthropometric and clinical variables: weight, waist to hip ratio, body composition and bone mineral density 6. Systolic and diastolic blood pressure 7. Physical function 8. Lifestyle parameters: sleep quality, quality of life and eating habits
