Effects Of Strength Training On Muscle Hypertrophy And Muscle Cell Disruption In Older Men (2nd Study)

The following definitions will be helpful in understanding the studies dealing with muscle injury responses to strength training.

Delayed Onset Muscle Soreness:
Severe muscular discomfort occurring 1-3 days after performing exercise.

DEXA:
Dual-Energy X-ray Absorptiometry - a scientific test using x-ray technology to determine body composition.

MRI:
Magnetic Resonance Imaging - a scientific test that uses magnetic fields and radio waves to produce colorful images which differentiate between muscle and fat.

Miometric Muscle Action:
Refers to shortening of the muscles, often referred to as concentric contractions; also called positive work.

Muscle Hypertrophy:
An increase in muscle size.

Pliometric Muscle Action:
Refers to lengthening of the muscles, often referred to as eccentric contractions; also called negative work.
