a muscle that contracts and shortens as a weight is lifted.
A concentric contraction is
the contracting muscle that initiates movement.
A muscle agonist is
the opposing (relaxing) muscle during muscle contraction.
A muscle antagonist is
one lift.
A repetition (rep) is
8 to 12 exercises.
According the ACSM, basic health fitness benefits can be obtained by lifting in a single set of
a muscle that contracts and lengthens as a weight is lowered.
An eccentric contraction is
enhanced flexibility.
Benefits of strength training include weight control, time economy, injury prevention, increased bone strength, and
high blood pressure.
Cautions for strength training include seeking medical clearance for those who have cardiovascular problems, hernia, arth ritis, lower back problems, or
heavy weights for strength, light weights for endurance.
Differences between tra ining programs for strength and muscular endurance include lifting
is not a complete exercise program.
Disadvantages of strength training are that injury is possible, you may need equipment, it can initially produce mu scle soreness, and it
It reduces risk factors associated with cardiovascular disease.
How does resistance training affect cardiovascular health?
lower back problems.
Individuals who should seek medical guidance prior to starting a weight-training program include people with high blood pressure, hernias, arthritis, or
disus e.
Loss of muscle mass as one grows older is primarily due to
graduall y increasing the load or number of reps lifted.
Progressive overload is
one maximal lift.
Repetition maximum (1 RM) means
a muscle contracts and shortens as force is controlled.
