1.   Explain the effect that periods of recovery have on the force of a muscle, as compared to a continuous multiple stimulus fatigue.

2.   Does the number of recovery periods or the lengths of those recovery periods affect the force the muscle can exert? Explain your answer.

1.   Explain what is meant by active force and passive force.


2.   Explain why total force increases and decreases as the length of the muscle varies.


1.   What type of contraction occurred when the 2.0g weight was attached to the muscle?
   

2.   Explain the relationship between resistance and the velocity of shortening.



3.   Explain the relationship between resistance and distance lifted.


4.   If you tried to lift something very heavy, like your car, your muscles would contract and tire quickly. What type of muscle contraction occurs in this instance? Explain why your muscles would be unable to fully shorten, causing your attempts at lifting the car to fail.



5.   In an attempt to "bulk up" and increase the size of your muscles, you have begun a regular swimming regimen, in which you swim 30 minutes each day, four days each unit. After a month has passed, you notice that your stamina in the pool increases—you can swim much farther before your muscles begin to tire. However, your muscle size has not visibly increased. What type of exercises should you include in your daily regimen to build muscle size? Explain your answer. 



6.   If the fuel source for muscle contraction comes from the bloodstream, can you target specific areas of the body to “spot reduce” fat? For example, will lengthy sessions of repetitive abdominal crunches or sit-ups decrease the fat around the abdomen?

When there are periods of recovery on the force of a muscle, the muscle is able to quickly repair itself and continue to retain force as opposed to a continuous multiple stimulus fatigue.

2.   Does the number of recovery periods or the lengths of those recovery periods affect the force the muscle can exert? Explain your answer.

Yes, the longer the recovery periods and longer the recovery period, the more the  muscle is able to exert. If the muscle has time to recover, it will regain strength and exert energy again.
