If the fingers had large motor units in relation to the efforts of typing and writing, several potential outcomes could occur:
1. Reduced precision: Large motor units are responsible for generating strong and forceful contractions. If the fingers had large motor units, it could result in reduced precision and finer motor control. This could make it challenging to perform tasks that require delicate movements, such as typing or writing with accuracy.
2. Difficulty in fine motor tasks: Fine motor tasks, like typing and writing, require coordinated and precise movements of the fingers. If the fingers had large motor units, the force generated by these units might be excessive for these tasks, leading to difficulties in controlling the movements. This could result in reduced dexterity and accuracy in typing or writing.
3. Increased fatigue: Large motor units are associated with generating more forceful contractions. If the fingers had large motor units, it would require more effort and energy to perform typing or writing tasks. This increased effort could lead to quicker fatigue and tiredness in the fingers and hand muscles, making it challenging to sustain these activities for extended periods.
4. Potential for increased strength: On the positive side, having large motor units in the fingers might provide increased strength for tasks that require forceful gripping or squeezing, such as holding objects or performing manual labor. However, it is important to note that excessive force generation could still impact fine motor skills and precision.
Overall, if the fingers had large motor units in relation to the efforts of typing and writing, it could potentially result in reduced precision, difficulties in fine motor tasks, increased fatigue, and possible increased strength for forceful activities. However, it's important to note that this scenario is hypothetical, and the actual impact would depend on various factors, including the specific characteristics of the large motor units and the individual's adaptation and practice in performing the tasks.
