Exercise Training on Health and Medical Costs of Metabolic Syndrome Individuals. (EXEisMED)

Effectiveness of Exercise Training on Health and Medical Costs of Metabolic Syndrome Factors in the Adult Population.

The purpose of this study is to determine if an exercise training intervention together with conventional medical treatment can decrease the annual healthcare cost in patients with metabolic syndrome.

It is proposed a multicentral clinical trial with cluster randomization among research nodes located in towns of Castilla-La Mancha and Toledo neighborhoods (Spain). The aim is to compare the annual healthcare cost of patients receiving conventional medical treatment against patients receiving the same intervention plus exercise training for 16 weeks. Exercise training will be based on high-intensity interval training conducted on stationary bikes, and strength training using weight-bearing exercises. Each research node will be composed of the clinical center and the sports facilities available in the town/neighborhood. Research nodes will be randomized into two experimental interventions: i.) conventional medical treatment, and ii.) conventional medical treatment + exercise training. After verbal and written information about the study and related potential risks, all patients fulfilling inclusion criteria will be included after giving written informed consent. At baseline, and after 12 and 24 months, annual healthcare costs will be obtained from the volunteers' clinical records. In addition, at baseline, and after 4, 12, and 24 months, metabolic syndrome components prevalence, metabolic syndrome z-score, body composition, and cardiorespiratory fitness will be tested.

Volunteers will maintain habitual medical treatment and will participate in a 16-week exercise training based on high-intensity interval training (stationary bikes), and strength training (weight-bearing exercises).

participants will maintain habitual medical treatment prescribed by primary care and specialized physicians from the public health service.

From unified medical records, all clinical and paraclinical interventions including pharmacological treatment, diagnostic or therapeutic procedures and primary care and specialized medical consultations will be included

Measurement of the mass of man body compartments (i.e., fat mass, fat free mass, and bone mass) by dual energy x-ray absorptiometry.

Serum concentrations (in mg per dL) of triglycerides, total colesterol, high density lipoprotein after 8-hour fasting

Systolic and diastolic values of blood pressure measures obtained from the brachial artery after 15 min of supine rest.

Measurement of waist circumference (cm) in a horizontal plane, midway between the inferior margin of the ribs and the superior border of the iliac crest.

From the exercise training sessions records (exercise time in minutes), measurement of volume prescription (Target time)

From the exercise training sessions records (heart rate in beats per minute), measurement of compliance to exercise intensity prescription (target HR).

Inclusion Criteria: Fulfilling criteria for metabolic syndrome diagnosis. Exclusion Criteria: At baseline, engagement to an exercise training program for the last 6 months.
