An analysis of the correlation between kinesthetic differentiation capacity and the maximum force level in lower limbs

Abstract

BackgroundAmong specific coordination abilities, kinesthetic differentiation capacity of movement belongs to the most crucial factors fostering rational human behavior in the surrounding environment. The capacity is universal -indispensable in nearly all sports disciplines. One of the most important constituent elements of kinesthetic differentiation is the so-called "force sense," defined as differentiation of movement with respect to administering appropriate force. The authors of the study analyzed the correlation between the maximum force level in lower limbs and the accuracy of applying a targeted force value. Material/MethodsThe study was conducted on 54 participants, students from the University School of Physical Education in Wrocław. To determine the maximum force (Fmax) and force sense in lower limbs, a specialist device was used, "the characterograph of muscle strength in limbs". ResultsThe mean force sense was 43.28 N in the participants' left lower limbs, and 58.33 N in the right limbs. The mean maximum force (Fmax) was higher in the right lower limb (897.17 N) than in the left one (769.94 N). The correlation coefficient between the variables of the maximum force level and the force sense in the left lower limb was 0.38. The same level of correlation was observed for the right lower limb (0.37). ConclusionsThe positive correlation observed between the higher level of maximum force and kinesthetic differentiation of lower limbs in students from the University School of Physical Education in Wrocław implies that a training session appropriately planned to raise the maximum force level may positively influence the force sense value.

Relationship between Joint Position Sense, Force Sense, and Muscle Strength and the Impact of Gymnastic Training on Proprioception

“…It is possible that the cocontraction of the antagonist muscle group contributes to joint stabilization allowing for greater FR accuracy [ 42 , 43 ]. A lack of correlation between FR and agonist MS is consistent with previous research which found no significant correlation between agonist MS and FS in the knee joint of untrained adults [ 44 ]. In case of gymnasts, the relationship between antagonist MS and FS accuracy was seen only during 20% MVC flexion and involved ALM-normalized peak torque of extensors instead of absolute values.…”
