grip force . dumimicta
Hypothesis (2 points): Hand dominance would have an
effect On the max grip force and less fatigue
and the results for domu nant' hand being greater than

Data and Calculations
ofor Unit Recruitment
complete Table 2 . 1 using Dominant arm and Non- Dominant arm data . In the&quot; Assigned Force Increment&quot;
column , note what each horizontal grid line represents in Kilograms , with the first beside Peak # 1 . The
``clements are shown to the far right of the graph recording ( i.e. 10 , 20 , 30 OR S , 10, 15 , etc. ). Although there
are eight rows in Table 2. 1 . you will only have to fill it in up to the subject's maximum force reached ( e.g . if the
Subject only reached up to the fourth grid line , then only four rows need to be completed ) .
