Can Proprioceptive Training Enhance Fatigability And Decrease Progression Rate Of Sarcopenia In Seniors? A Novel Approach.

Sarcopenia is a common condition in older adults. Sarcopenia causes frequent occurrence of muscle fatigue. Muscle fatigue commonly develops among seniors. Muscle fatigue is a type of physical fatigue that occurs due to either motor or sensory dysfunctions. Current interventions developed to decrease the occurrence of muscle fatigue includes either increasing rest periods or subdividing large tasks into small ones. The effectiveness of these interventions is highly contradicted. Recently, researchers discovered that mechanoreceptors are the main receptors of muscle fatigue, however, no clinical study investigated the effect of performing proprioceptive training to enhance the mechanoreceptors and decreasing the occurrence of muscle fatigue. Performing proprioceptive training could improve muscle fatigue by improving its sensory part. The function of mechanoreceptors, consequently might enhance fatigability and decrease the progression rate of sarcopenia. Thus, this review was conducted to suggest a novel approach of treatment to enhance fatigability and decrease Sarcopenia in seniors. This might be accomplished through increasing the firing rate of alpha-motor neurons, increasing the amount of Ca2+ ions in the neuromuscular junction, slowing the progression rate of Sarcopenia, and correcting movement deviations commonly occur with muscle fatigue in seniors. In conclusion, proprioceptive training could be an effective role in decreasing the progression rate of Sarcopenia and enhance the fatigability among seniors.
