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

الملخص EN

The aims of this study were (1) to assess the relationship between joint position (JPS) and force sense (FS) and muscle strength (MS) and (2) to evaluate the impact of long-term gymnastic training on particular proprioception aspects and their correlations.

17 elite adult gymnasts and 24 untrained, matched controls performed an active reproduction (AR) and passive reproduction (PR) task and a force reproduction (FR) task at the elbow joint.

Intergroup differences and the relationship between JPS, FS, and MS were evaluated.

While there was no difference in AR or PR between groups, absolute error in the control group was higher during the PR task (7.15 ± 2.72°) than during the AR task (3.1 ± 1.93°).

Mean relative error in the control group was 61% higher in the elbow extensors than in the elbow flexors during 50% FR, while the gymnast group had similar results in both reciprocal muscles.

There was no linear correlation between JPS and FS in either group; however, FR was negatively correlated with antagonist MS.

In conclusion, this study found no evidence for a relationship between the accuracy of FS and JPS at the elbow joint.

Long-term gymnastic training improves the JPS and FS of the elbow extensors.
