Term
tendons:
Definition
connect a skeletal muscle to a bone
Term
the latency period is the time:
Definition
period between stimulation and the shortening of the skeletal muscle
Term
duration of the latency period:
Definition
increases with weight
Term
the amount of work done by a skeletal muscle is:
Definition
distance the weight is lifted multiplied by the weight
Term
electrical shock stimulates the muscle, which contracts and lifts the weight. the distance the weight is lifted is:
Definition
displacement transducer
Term
what is the effect of increasing the weight on the latency period?
Definition
latency period increased as the weight increased
Term
during the latency period:
Definition
the muscle was contracting isometrically
Term
increasing the weight increased the latency period because:
Definition
it takes time to build up tension in the muscle and the tendon to overcome the weight
Term
immediately after the latency period has passed:
Definition
muscle contracted isotonically and lifted the weight
Term
relationship between the amount of muscle shortening and weight
Definition
amount of muscle shortening generally decreased as the weight was increased
Term
predict the amount of isotonic contraction with a weight of 300
Definition
muscle would not shorten, because the isometric contraction could not overcome such a heavy weight
Term
determine the relationship between work and weight
Definition
work done by the contraction increased to a maximum value and then decreased
Term
when compared with the response for a lighter weight like 40g, the response for the 120g weight:
Definition
both of the above statements are true
