Abstract EN

1- Identify the relationship between some variables of skill performance and the performance time of 200 meters issued.

2- Identify the relationship between the range of motion and some variables of skill performance and the performance time of 200 meters issued.

Study procedures: The used approach: The researcher used the descriptive approach to suit the scheduling of the study.

Study sample: The researcher used a sample of 16 National Bank swimmers, born in 2003-2004.

Research tools and devices: forms - standard medical scale - Rastamer.

Research metrics: Basic measurements: (height - weight - body mass index).

Physical measurements: 1- Measurements of maximum strength: (Maximum right metatarsal extension force - right metatarsal bend maximum force - right knee bend force - right grip force - right - vertical jump - north metatarsal extension maximum force - left metatarsal bend maximum force - left knee flexion maximum force - grip strength North).

2- Range of motion measurements: - Positive range of motion for bending movement of the right foot joint.

- The passive range of motion of the bending movement of the right foot joint.

- Flexibility surplus right.

- Measurement of the positive range of motion of the extension motion of the right foot joint.

- The passive range of motion of the extension motion of the right foot joint.

- Flexibility surplus right.

- The positive range of motion of the knee joint rotation of the lateral side from the knee flexion position 90 degrees to the right.

- Passive range of motion of the lateral knee joint rotation from the knee flexion position 90 degrees to the right.

- Flexibility surplus right.

- The positive range of motion of the bending movement of the right shoulder joint.

- The passive range of motion of the bending movement of the shoulder joint to the right.

- Excess flexibility right - the positive range of motion of the bending movement of the knee joint right.

- Passive range of motion of the bending movement of the knee joint right - Excess flexibility right.

- The positive range of motion of the flexion movement of the wrist joint north.

- The passive range of motion of the flexion movement of the wrist joint north.

- Excess elasticity north - a measure of the positive range of motion of the tidal motion of the wrist joint north.

- The negative range of motion of the tidal motion of the wrist joint north.

- Passive range of motion of the knee joint rotation of the lateral side from the knee flexion position 90 ° N.

- Flexibility surplus north.

- The positive range of motion of the flexion movement of the shoulder joint north.

- The passive range of motion of the flexion movement of the shoulder joint north.

- Excess elasticity north - positive range of motion of the flexion movement of the knee joint north.

- The passive range of motion of the flexion movement of the knee joint north.

Second: skill measurements: 1- Measurements of skill performance: Strikes the arms.

- The two legs blows.

Breathing 2- Time measurements: Swimming speed is 25 meters, strikes two legs, chest.

Swimming speed is 25 m full chest.

Swimming speed 100 m full chest.

Strike length (100 m) chest.

- Strike time (100 m) released.

- Strike frequency (100m) released.

- A time 200 AD released.

Basic study: 1- The sample: 16 swimmers were selected from the National Bank club, and they were chosen according to the preference of time.

2- Spatial domain: The National Bank of Alexandria club.

3- Time domain: Measurements were made in the 2019 training season.

Main results: - The presence of a statistically significant implicit correlation relationship at a level of 0.05 between the maximum strength variables and each of the swimming speed is 25 m for two chest strikes, the swimming speed is 25 m in full chest, the swimming speed is 100 m in the full chest, the time of the blow is (100 m) chest and the length of the stroke is (100 m) chest.

Strike frequency (100m) released.

- The presence of a statistically significant mean correlation relationship at the level of 0.05 between the variables of maximum strength, farmers' strokes, leg strikes, and breathing.

- The presence of a statistically significant denial correlation relationship at 0.05 level between the variables of maximum strength and 200-meter chest time.

- The presence of a statistically significant significant correlation relationship at a level of 0.05 between the measurements of flexibility and each of the measurements of swimming speed of 25 meters, two leg strokes in the chest, swimming speed of 25 meters, full chest, swimming speed of 100 meters, full chest, stroke time (100 meters) chest, length of stroke (100 meters), chest frequency Strike (100m) was released.

- There was a significant statistically significant correlation relationship at 0.05 between elastic measurements and 200 meters time.

- There was a statistically significant significant correlation at 0.05 between measures of flexibility, farmers' strokes, leg strokes, and breathing.
