The results indicate
that the hypotheses made were able to be supported by data collected throughout
this experiment. During the mild submaximal trial, 25.09 percent of the maximum
voluntary contraction was generated. It is reasonable to say that only 25.09%
of maximum voluntary contraction was being generated since only 20% of the
participant’s maximum force was generated in the mild submax trial. Not all
motor units were being recruited and rate coded at this lower submax, therefore
producing less force and a smaller contraction of the biceps brachii
(Robertson, 2004). 48.72 percent of the maximum voluntary contraction was
generated during the medium submaximal trial. Lastly, 84.84 percent of the
maximum voluntary contraction was generated during the strong submaximal trial.
As the percentage of submax increases from mild to strong, the % of MVC and
amplitude of EMG increases along with force.
The participant’s graph to represent this had a positive relationship.
Generally, the relationship between the force produced by the biceps brachii
muscle and EMG should be seen as a positive, non-linear relationship, however,
the graph computer for our participant was not non-linear as should be expected
