Effects of muscular fatigue on knee proprioception during performance and recovery of the knee flexors in female physical education students

الملخص EN

The purpose of this study was to assess the effect of muscular fatigue on the knee proprioception of female's physical education students.

Sixteen physical education female students participated in this study from Sport Science College in Mutah University.

All students were registered in basketball-2 courses classes during fall semester 2010/2011.

Both limbs were used in this study; the dominant limb was used as experimental and nondominant limb was used as control one.

An effect of muscular fatigue on proprioception performance was measured by the method of absolute reproduction angular error (i.e.

differences in subject angular reproduction to the angle set by the examiner).

The researcher used separate three-factor ANOVAs to calculate the mean and standard deviation for the study; and the goniometer has been used to calculate the differences between the angle set by the examiner and the angle reproduction by the subject.

The results indicated that there was no significant difference been the dominant and non-dominant limb before fatigue intervention, p≤ 0.05.

Also, indicted that there was no significant difference between the dominant and non-dominant limb after fatigue intervention, p≤ 0.05.

Also results indicted that there was a significant difference between the dominant and non- dominant limb after recovery.

In conclusion there was no significant difference of knee joint proprioception after fatigue intervention between the dominant limb, and the control limb, where alpha level set at (0.05) level of significance.

However, the details of proprioception are still largely unknown.

It is known that proprioception is necessary for normal functional activities in sport event, and loss of proprioception seriously impedes coordination and influence one to have injuries and re-injuries; also, there was a significant difference of knee joint proprioception after fatigue intervention and recovery time between the dominant limb, and the control limb.

Therefore, more research is needed to verify the effects of fatigue on proprioception around the knee joint among female's athletes.
