NCT02350465

Brief Summary

The objectives of this study are to: 1) validate a rapid, portable, cost-effective method for screening myosteatosis and sarcopenia using diagnostic ultrasound, and 2) investigate a novel approach to progressive resistance exercise involving eccentric muscle actions that will counter the local effects of myosteatosis and sarcopenia in African Americans.

Outcome Measures

Primary Outcomes (1)

  • Change from Baseline in Sonographic Lean Body Mass at 3 months

    US estimates of aggregate regional LBM (muscle thickness, cm), will be assessed using B-mode diagnostic US with a 13-6 megahertz (MHz) linear array transducer for morphology measures at 6 axial and appendicular sites.

    At study baseline for all subjects, and at Week 6 and 12 of the intervention period for subjects randomly assigned to an exercise group

Secondary Outcomes (4)

  • Change from Baseline in dual-energy X-ray absorptiometry (DXA) scanning at 3 months

    At study baseline for all subjects, and at Week 12 of the intervention period for subjects randomly assigned to an exercise group

  • Change from Baseline in metabolic status at 3 months

    At study baseline for all subjects

  • Change from Baseline in intramuscular adipose tissue assessment at 3 months

    At study baseline for all subjects

  • Change from Baseline in strength assessment at 3 months

    At study baseline for all subjects, and at Week 6 and 12 of the intervention period for subjects randomly assigned to an exercise group

Study Arms (2)

Eccentric Exercise

EXPERIMENTAL

Supervised strengthening exercise using eccentric muscle actions.

Behavioral: Eccentric Exercise

Concentric Exercise

ACTIVE COMPARATOR

Supervised strengthening exercise using concentric muscle actions.

Behavioral: Concentric Exercise

Interventions

Submaximal progressive resistance exercise (PRE) using eccentric muscle actions for the knee extensors/flexors will be performed for 10 repetitions, 3 to 4 sets, twice per week for 12 weeks.

Also known as: Negative work training
Eccentric Exercise

Submaximal progressive resistance exercise (PRE) using concentric muscle actions for the knee extensors/flexors will be performed for 10 repetitions, 3 to 4 sets, twice per week for 12 weeks.

Also known as: Conventional strength training

Eligibility Criteria

Age18 Years - 85 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • An African American adult.
  • Between 18 and 30 years of age, or between 65 and 85 years of age.
  • Able to independently walk at home and in your community (use of an assistive device like a cane or a walker is acceptable).

You may not qualify if:

  • Uncontrolled hypertension or other cardiovascular disease.
  • A musculoskeletal condition that would stop you from performing the physical assessment tests.
  • Muscle weakness due to neurological disease or injury (such as stroke or spinal cord injury).
  • Moderate to severe sepsis (blood infection) or edema (such as swelling of a limb).
  • Been hospitalized over the last three months.
  • History of a broken arm or leg bone because of osteoporosis.
