A the greatest difference between all ten trials is

a. The greatest difference between all ten trials is 15 contractions and the least
amount of difference between all ten trials is 0. But in trial #8, the contraction was
one more than trial #7. The overall average difference between all ten trials is
about 4.3 contractions.
3. What do the line on the graph tell you about the functioning of the muscle during intense,
repeated exercise?
a. The functioning of the muscle during intense, repeated exercise decreases. The
number of contractions decreases on both the right and left hand as each trial is
performed from trial #1 to trial #10.
4. Add up the number of contractions over the ten trials for each hand and record the total in

the data table. Then calculate the average number of contractions for each hand and
record the average in the data table. Compare the total and average numbers between
your two hands. Account for the differences that you observed between your right and left
hand.
a. The left hand have a total of 436 contractions and an average of 43.6 contractions
while the right hand have a total of 559 contractions and an average of 55.9
contractions. The right hand (which is my dominant hand) perform better with a
little more resistance to muscle fatigue than the left hand. The difference between
the average contractions between the left and right hand is 12.3 contractions.
