Finger Force Production
Grip strength is affected by many factors, body position, hand placement, arm angle, finger length, finger span and more. Finger forces change involuntarily during multi-finger force-production tasks. This can even occur when a digit's involvement in a task is not consciously neurally activated. The interaction between fingers has been classified as the finger enslaving effect, force sharing effect and force deficit effect.
Finger Enslaving Effect - the involuntary force production by fingers not explicitly involved in a force-production task. A person can produce force with one, two or three fingers and the other digits of the hand will contribute, how much has to do with the grip span of the force producing digits.
Force Deficit Effect - is a drop in peak force of a multi-finger task as compared to the sum of each individual fingers peak force in single-finger tasks.
Force Sharing Effect- in a multi-digit task is the ratio of the individual digit forces to the total peak force of all the digits.
The complexity of individual fingers to produce the needed power requires the athlete to select numerous training implements that necessitate a variety of hand and finger placements to assure maximal development of strength.
