Purpose: Neuromuscular and biomechanical factors in ACL injuries are among modifiable risk factors. The purpose of the present study was to evaluate the effect of feedback and feed forward neuromuscular training on balance and isometric strength in female basketball players with a high risk of injury in Kerman.
Method: The present research is semi-experimental, prospective study and the subjects selected objectively based on inclusion and exclusion criteria. Twenty women basketball players of Kerman city purposely selected and who were randomly divided into two groups of feed forward (age=15.73 ±0.78, weigh =61.38±9.09, height = 164.40 ±6.68) and feedback (age=14.70±1.33, weigh =56.31±8.38, height = 161.66±6.02) The training program designed based on the previous studies and conducted during 8 weeks, three sessions per week (each session 15 to 20 minutes) under the supervision of the examiner. Dynamic balance and isometric knee strength was measured using Biodex system and MMT device. One way ANCOVA was used for data analyze.
Result: The results showed significant differences between pre-post test balance Overall Stability index, internal/external index and Anterior/Posterior index (P=0.001).Significant difference was observed in the strength of quadriceps muscle and hamstring muscle between the two groups of feedback and feed forward exercises (P≥0.05). Also, the results of the paired sample t-test showed that Overall Stability in the feedback and feedforward group (0.345% and 0.19%), Balance Anterior/Posterior in the feedback and feedforward group(0.409% and 0.22%) and Balance Medial/Lateral in the feedback and feedforward group(0.427% and 0.22%) has significantly improvement compared to the pre-test (p<0.002).Isometric Quadriceps strength in the post- test showed an significantly improvement of 2.16% in feedback group and 1.82% in feedforward group compared to the pre-test (P=0.001). Isometric hamstring strength in the post- test showed a significantly improvement of 2.07% in feedback group and 1.95% in feedforward group compared to the pre-test (P=0.001).
Conclusion: It can be concluded that neuromuscular training can enhanced balance and isometric strength, of women and training with feedback has more important than training with feedforward.
