Eligibility Criteria
Inclusion
- Regardless of training status, age range will be from age 18 to 45. We will be limiting the upper age range because increased age is associated with sarcopenia and alteration of fiber type 29 and we would like to limit the confounding effects of age.
- We will define the lean group by a BMI of \< 25 kg/m2. Weight must be stable \[+/- 5 pounds\] for at least the three months prior to the study for all participants.
- The untrained subjects must not be engaged in a regular exercise program (\< 30 minutes regular exercise over 1 week).
- The trained subjects should be participating in regular running exercise (\> 45 min/day, ≥ 5 days/week) and preferably be currently or recently participating in competitions (within 2 years).
Exclusion
- Regardless of training status, subjects must not be on medications that may affect lipid levels, specifically lipid lowering agents, birth control pills or diuretics.
- The subjects should not be on a high fat diet (\> 45% fat) as measured by a screening questionnaire. We will also administer a PAR-Q questionnaire (attached) to establish whether the subject will be safe for exercise testing. - The female subjects must not be pregnant. A pregnancy test will be performed prior to all study visits.
- If screening TG are \> 300 (based on 1st visit results) or fasting glucose \> 100 (based on 1st visit results), the subjects will be excluded.
- If the subject is allergic to eggs (used in lipid emulsions), soybeans(used in lipid emulsions), or lipid emulsions the subject will be excluded from the study.
- Subjects taking anti-platelet agents (if anti-platelet agent cannot be held for seven days) and subjects taking anticoagulation therapy will be excluded.
- Subjects with clinically significant medical issues or a history of hematologic (platelets \< 100), hepatic (LFTs \> 2X nl), renal (Cr \> 1.5), pulmonary, or cardiac abnormalities (including abnormal EKG) will also be excluded.
