Abstract EN

Research’s aims : To realize : 1.

The values of some of Biokinematics variables in the takeoff phase in high jump in Fuasbory method.

2.

The values of some of force-time function variables in the takeoff phase in high jump in Fuasbory method.

3.

The correlation between the Biokinematics variables and force-time function in the takeoff phase in high jump in Fuasbory method.

The researcher has applied the descriptive method for its convenience with the nature of the research.

The researcher choose the sample of physical education college students / university of Mosul The research sample has consisted of (5) in high jump in Fuasbory method as while as the best jumper in all phases on the yaer2011-2012.

Each jumper was given (3) trials in each height according to the international law of track and field games.

All the trials were filmed and the best trial was analyzed.

The sample subjects have been filmed by using two video cameras that ( 25 ) frame / second in the high speed type Sony Japanese fashion as well as using the force platform of measuring ground reaction force prepared for this purpose.

Then the researcher extracts areas and shapes of force –time function by Planomeetr equipment which measured unlike regular areas.

After the analysis was achieved, data were statistically handled by applying SPSS application.

Statistical means applied in the research are as follows: (arithmetic mean, standard deviation, Person simple corre1lation coefficient, variance coefficient and percentage).

The research Conclusions this : 1 .

Has been significant relationship between some of the kinematics variables in time climb phase and angler velocity and circumference velocity and the highest of body mass center of gravity's with some of force –time function like area and time in different phases of (impact–absorb–push) in the take-off phase in high jump in Fuasbory method.

2 The less of time and area under the curve of absorb phase has positive inversion on the force–time function variables in push phase in the take-off phase in high jump in fuasbory method.

3 .

Maximum force of reaction in the hit phase play effective part as the climb phase dependence on the climb force for crossing the bar as well as became highest.

4 .

Pluralism the ankle angle of take of leg and the angle of knee to rest on leg the important factor to definition the trunk angle opportunity to realization best achievement in high jump in Fuasbory method.

The researcher has recommended the following : 1.

Reducing the absorption phase as much as possible in terms of time saving the generated force during the impact phase in order to invest this measure in the take-off phase in high jump in Fuasbory method.

2 .

.

Developing the body angular velocity during the pushing phase for its positive reactions on real in the take-off phase in high jump in Fuasbory method.

3 .

Confirmation on the performance as much as possible achievement of force generation associated with velocity to attain the best achievement in high jump with Fuasbory method.

4 .

Use the video films style and movement analyzes by coaches and researchers by using modern equipment in order to find out the most important points of developing the technical performance for different activities and high jump one of them.
