أثر تمرينات المستقبلات الحسية العضلية (P. N. F)‎ في تحسين التوازن العضلي (Muscular balance)‎ و الصفات البدنية الخاصة لمتسابقي الوثبة الثلاثية المتقدمين

Abstract EN

The triple jump event is one of the events with special requirements for jumpers in terms of physical and technical capabilities, in which the movements of the jumper change in terms of approaching fast idealism and advancements (hopscotch step and jump) and for each of these leaps a percentage of total distance completion for the jumper.

In spite of the continuous training on the technical stages of the event, the achievement is still weak and that the physical exercise that are designed by coaches must be targeted to address one of the deficiencies specified in physical performance or technical for the jumper.

Bring out the muscle power of the jumper while approaching or during the three phases of jumping requires a high level of muscular equilibrium level (muscular balance) either of the body sides (right - left) or in one of the muscles parties, especially in the joints and the parties involved in this event basically are the hip, knee, foot, shoulder and muscles put on them.

Here lies the importance of the research in preparing Proprioceptive Neuromuscular Facilitation (PNF) with the method of Rebeat Contraction (R.C) to improve the balance of muscle strength between the sides of the body (the right - the left) as well as the muscular balance of the one-side muscles for the muscles involved in the main joints of the advanced triple jumper.
