Sensory system and muscular contraction are connected. The sensation starts by stimulating the receptors, which send impulses to the brain, brain processes them and sends feedback to the muscles in order for them to get accurate information and activate. One of the most important sensations is a proprioceptive that sends information about body position. The aim of this paper was testing surface sensitivityin the area of m.gastrocnemius in standing still position, and in squat on full foot and toes position also testing whether there is a difference in surface sensitivity between the dominant and undominant leg. In this research there were 10 examinees, 5 of them were male and 5 5 of them were female, on each examinee was preformed 3 measurements. All the examinees were students from Faculty of Health Studies in Rijeka, at the age of 21 to 24 years, without previous diseases related to the nervous system and locomotor system. The chose group is specific because of the age and physical activity to make the researche more credible. Research was conduted on a device called The Baseline 12-1480 Two Point Aestesiometer. The results have show that is no statistically significant difference in sensitivity between standing position, squat on the foot and squat on toes positions expect the difference between a man and a woman in full foot squat position (W=2,949; p=0,003) and toes squat position (W=2,223; p=0,026). Observing the sensitivity of men and women, men are less sensitive than women in standing position by 2.25, wich is no enough to be statistically significant (W=0,142). Squating on toes, men have higher degree of sensitivity meaning they felt it at a larger scale which shows that women have higher sensitivity by 2.50, indicaling that there is a statistically significant difference (W=2,294; p=0,003). Observing squat on toes position it has been found that there is a statistically significant difference (W=2,223; p=0,026) and the sensitivity is higher in men by 1.50 than in women.
