Kein Eingriff: 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.

Evaluate the effect of omega-3 fatty acids on muscle mass
Zeitfenster: 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
Zeitfenster: 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.
