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 wasone 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 andaverage numbers between your two hands. Account for the differences that you observed between your right and lefthand. 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.
