Brief Summary

Researchers are trying to understand how chronic inflammation affects muscle function and responses to exercise.They are also trying to determine if suppressing chronic inflammation using omega-3 fatty acids (n3-PUFA) restores skeletal muscle function and exercise responsiveness in older adults.

Outcome Measures

Primary Outcomes (4)

  • Change in Maximum Workload Muscle Strength

    Single-leg knee extensor strength was measured on a pneumatic resistance leg extension machine (Keiser Air300, Keiser Corporation, Fresno, CA, USA) and defined as the unilateral 1-repetition maximum (1-RM). Subjects performed a unilateral knee extension warm-up consisting of 10 repetitions at minimal resistance and 3 sets of 5-10 repetitions at increasing workloads. Subjects then performed a series of single repetition attempts at increasing workloads, each separated by 3 min of rest, until the maximum load that could be moved through the entire range of motion was reached. This maximum workload was defined as the individual 1-RM.

    baseline, 6 months

  • Body Mass Index (BMI)

    Subject's BMI calculated as weight in kilograms divided by height in meters squared. Uses measurements of height and weight obtained during study (with appropriate metric conversions). Measured as kg/m\^2

    baseline, 6 months

  • Body Fat

    Dexa Scan based body fat, measured as a percentage of body weight

    baseline, 6 months

  • Lean Body Mass

    Lean body mass as measured by a DEXA scan is the amount of soft tissue that is not fat or bone. Measured in kilograms.

    baseline, 6 months

Secondary Outcomes (3)

  • C-Reactive Protein (CRP)

    baseline, 6 months

  • Erythrocyte Sedimentation Rate (ESR)

    baseline, 6 months

  • Weight

Study Arms (2)

n3-PUFA

EXPERIMENTAL

Participants will be instructed to swallow 2 Docosahexaenoic acid (DHA)/EPA soft gels twice per day with meals (morning and evening) for a total of 4 soft gels per day.

Drug: n3-PUFAProcedure: BiopsyDiagnostic Test: Body Composition Scan

Placebo

PLACEBO COMPARATOR

Participants will be instructed to swallow 2 placebo soft gels twice per day with meals (morning and evening) for a total of 4 soft gels per day.

Drug: PlaceboProcedure: BiopsyDiagnostic Test: Body Composition Scan

Interventions

The DHA/EPA softgels will each contain \~465mg of EPA and \~375mg of DHA for a total daily dosage of 3.4g/day. Additionally, each capsule will contain SCI's proprietary Advance Lipid TechnologiesTM (ALTTM) containing the surfactants polysorbate 80, NF (\~381 mg) and poloxamer 237, NF (\~8.8 mg).

n3-PUFA

Looks exactly like the study drug but contains soybean oil with no active ingredient.

Placebo
BiopsyPROCEDURE

Two muscle biopsies from the upper part of one leg. A small (\~1cm) incision will be made through the skin, and a needle will then be used to remove the muscle.

Placebon3-PUFA
Body Composition ScanDIAGNOSTIC_TEST

Measure of body fat percentage, skeletal muscle mass, body water, and visceral fat.

Also known as: DEXA (dual-energy X-ray absorptiometry) scan.
Placebon3-PUFA
