Brief Summary
Prospective study on the structural and functional changes in the heart of adult women assessed by echocardiogram and in lipid metabolism that occur in response to physical training. Using echocardiogram we will characterize the early determinants of "athletic remodeling". We will also assess the effect of intense physical training on lipid metabolism, focus on HDL subspecies and function.

Other: prospective study with no intervention
Interventions
Prospective study with no intervention in women who have volunteered to run a full marathon or a half-marathon. Each subject will serve as own control. Each subject will be studies at 3 stages: baseline, after at least 12 weeks of training for the marathon (we will not provide training), 6 weeks after running the marathon.
Eligibility Criteria
Community sample. Participants will be recruited by invitation to volunteer in the study.
You may qualify if:
- Healthy adult men or women, aged 18 years or older
- Voluntarily signed up for a sport event or to run a marathon or a half marathon for the first time
- Normal to mildly elevated blood pressure (systolic blood pressure \< 140 mmHg and/or diastolic blood pressure \< 90 mmHg)
- Hormone replacement therapy and birth control pills are allowed, provided they have been on a stable dose for more than 3 months and no change in dose is planned for the duration of the study
- Capable and willing to provide written, informed consent for the study
You may not qualify if:
- History of cardiovascular disease within the past year (cardiomyopathy, heart failure, ischemic heart disease, stroke, TIA, peripheral vascular disease)
- Change in body weight more than 10% over the past year
- History of significant medical conditions, including respiratory, gastrointestinal, neuromuscular, neurological or musculoskeletal problems interfering with exercise.
- Autoimmune or collagen vascular diseases, chronic anemia,
- Malignancies in the past 5 years, with the exception of treated skin or breast cancer that did not require treatment with chemotherapy.
- Diabetes
- Pregnancy or recent delivery: delivery date less than 3 months prior to enrollment
- Lipid lowering medications (statins, niacin, resins) are allowed, provided dose has not changed for 3 months prior to enrollment and is not anticipated to change during the study
- Fish Oil supplements are allowed, provided dose has been unchanged for 3 months prior to enrollment and no change in dose is planned for the duration of the study.
