Fish Oil and Muscle Function

8 december 2014 uppdaterad av: Washington University School of Medicine

Omega-3 Fatty Acids, Muscle Mass and Muscle Function

The purpose of this study is to examine the effect of omega-3 fatty acid supplementation on changes in muscle mass, muscular strength and physical function.

Detaljerad beskrivning

Loss of muscle mass is a normal consequence of aging in many older adults, worsened by chronic illness, poor appetite and diet, and reduced physical activity. The ensuing decline in physical function is a major cause of frailty, disability and death. Treatments that can reverse or reduce the age-associated loss of muscle mass are therefore much needed. Evidence is emerging that consumption of fish or fish oil derived long-chain omega-3 polyunsaturated fatty acids (LCn-3PUFA) may be important for maintenance of muscle mass and physical function throughout the life-span. However, the effect of LCn-3PUFA supplementation on muscle mass, muscle strength and overall physical function is not known. The goal of this study therefore is to determine the effect of LCn-3PUFA supplementation on muscle mass, muscle strength and physical function in older adults.

  • Between 18 to 45 or between 60 and 85 y old
  • Subjects who are sedentary (<1 h of exercise/week)

Exclusion Criteria:

  • Subjects with evidence of significant organ system dysfunction (e.g. diabetes, severe cardiovascular disease, hyperlipidemia, cirrhosis, hypogonadism, uncontrolled hypo- or hyperthyroidism; uncontrolled hypertension)
  • Subjects with metal implants
  • Subjects with iron storage disease,

Placebo-jämförare: Majsolja
4 grams per day for 24 weeks
Experimentell: Long chain omega-3 fatty acids

Inget ingripande: Young healthy controls
Young subjects' muscle mass and physical function will be evaluated once (i.e., during baseline testing only). The data in young subjects will be used to determine the magnitude of the aging-induced decline in muscle mass and physical function in the older subjects prior to starting the interventions.

Tidsram
Evaluate the effect of omega-3 fatty acids on muscle mass
Tidsram: Change from baseline in muscle mass at 24 weeks in older adults only
We will measure thigh muscle volume by using magnetic resonance imaging. These measurements will also be assessed at week 12 in a subset of subjects but the data will not be used as a primary outcome measure.

Evaluate the effect of omega-3 fatty acids on physical function
Tidsram: Change from baseline in physical function at 24 weeks in older adults only
We will evaluate muscle strength by assessing one-repetition maximum strength of upper- and lower-body skeletal muscles, grip strength and isometric and isokinetic force development. We will assess overall physical function using the physical performance tests, which evaluates the ability to perform usual daily activities such as climbing a flight of stairs, walking 50 feet and putting on and removing a coat. These measurements will also be assessed at week 12 in a subset of subjects but the data will not be used as a primary outcome measure.

We will evaluate muscle strength by assessing one-repetition maximum strength of upper- and lower-body skeletal muscles, grip strength, thigh isometric and isokinetic force development and time-to-peak force development during thigh isokinetic exercises. We will assess overall physical function using the physical performance tests, which evaluates the ability to perform usual daily activities such as climbing a flight of stairs, walking 50 feet and putting on and removing a coat.
