EMG: Electrical activity of the muscle. Be very weary of big conclusions based on EMG because muscular electrical activity is far more complex than meets the eye and can often give misleading results. Many people try to take more information from it than is really available. I like to say it stands for "Extremely Meaningless Garbage" because it is so often misused, misrepresented, and misinterpreted.
Anabolism: as Quik said.
Catabolism: as Quik said.
Mechanical Advantage: Dealing with lever arms, this is a key point for physics and biomechanics. It is a ratio of the resisting to the applied force. If its value is greater than equal, it means that less effort is necessary to carry out a given work or weight lifting. In other words, it describes how much a lever multiplies the force put into it.
Kinematic: Technique. Looking at motion without regard to the forces that cause the motion.
Kinetic: Forces. Looking at the forces which result in motion.
Electromyographic: Same as EMG
Hypoxic: Less than normal oxygen levels.
Normoxic: Normal oxygen levels.
