ExLOH: Physical Exercise as a Sustainability Tool in Men With Dysmetabolic Hypogonadism
Study Details
Study Description
Brief Summary
Aim of this project is to delineate sustainable physical exercise programs and to assess the effects of such programs mainly on endocrine-metabolic and neurovegetative outcomes in a cohort of men with metabolic syndrome-related late-onset central hypogonadism.
Participants will undergo a personalised exercise program. After 6 months they will be subdivided into two groups, according to the weekly physical activity volume actually performed (above or below 600 MET·minutes/week). Changes in endocrine-metabolic and neurovegetative outcomes will be compared between the two groups.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Other: weekly physical activity volume performed above 600 MET·minutes/week Exercise program requiring clear definition of modality, intensity, frequency, duration and progression of exercise, tailored on patient's clinical conditions and goals. |
Behavioral: Structured and personalized program of physical exercise
In line with the most recent guidelines, exercise prescription will require the clear definition of modality, intensity, frequency, duration and progression of exercise, tailored on patient's clinical conditions and goals.
This intervention will be accompanied by a nutrition program aiming for proper dietary habits in terms of both quantity and quality.
