The Future of Education

The article provides results of pedagogical experiment on the use of instructional techniques, aimed at reducing the motor asymmetry in legs. The goal of this technique is to improve the quality of teaching students the hurdling technique at the Faculty of Physical Education.

The authors concretize the concept of the "lead leg" by replacing it with an intuitive preference in the choice of takeoff leg and its priority determined by the highest result of the strength endurance test. Authors revealed the dependence of the spatial and temporal parameters that determine the loss of speed when hurdling from the match/mismatch of the preferences in takeoff leg with strength priority of this leg. We found that the preference in the leg which allows achieving the best athletic results is associated with a type of physical exercise. The leg which has priority in one exercise may has no priority in the other.

The most informative test for the hurdling is a test on the strength endurance to identify priority leg. The test includes the wall squat with time control, separately for the left and right leg.

In hurdling students use as takeoff leg both "strong" and "weak" legs which were determined in the strength endurance test. Using of "strong leg" as takeoff leg was accompanied by speed increasing in the phase of attack of hurdle. Landing on the "weak leg" led to the loss of speed in the first step of the next hurdle cycle. However, the coefficient of relative effectiveness in this group was higher in comparison with the group which used "weak leg".

Exercises with a focus on more powerful repulsion for students with a "weak" takeoff leg allow increasing the coefficient of relative effectiveness of hurdling in this group in comparison with the same group which didn’t undergo such exercises.

Thus, the decrease in the leg motor asymmetry as a result of special exercises helps to reduce the loss of speed in hurdling.
