Core Strength Training on Anaerobic Power And Core Strength in Basketball Players
Condition: Sports Physical Therapy
Study type: Interventional

Summary: 
      The aim of the study is to investigate the effect of injury prevention program with core
      strength training support on anaerobic power and core strength in woman basketball Players In
      this direction, it is expected that the program will contribute to the decrease in the
      incidence of injury, the vertical jump distance, which is an indicator of anaerobic power,
      and the increase of core muscle strength.
    

Detailed description: 
      This study was approved by the ethics committee of Istanbul University Istanbul Faculty of
      Medicine.It will be done in the Exercise Test Laboratory of the Department of Medicine.

      Istanbul University youth women's basketball team and Galatasaray youth women's youth
      basketball teams will be included in the study.The Vertical Jump test, Cybex Isokinetic Core
      Strength Assessment will be measured before and after the 8-week exercise training for both
      the study and control group.The sample group of the study was found to be 40 people as a
      result of the statistical analysis made with reference to the peak torque.

      First of all, people will be informed about the "Informed Voluntary Consent Form" and the
      study will be explained. Then, volunteers who agree to participate in the study and meet the
      criteria for participation in the study will be asked to read the "Informed Voluntary Consent
      Form" or sign it themselves or their legal guardians.

      Athletes will be distributed into two groups by randomization method. The 1st group (working
      group) will apply the additional warm-up program to the core training program, which will be
      included in the routine training of the team, for 8 weeks, the 2nd group (control group) will
      continue their routine training programs.

      Cybex Isokinetic Core Force Assessment: Core strength will be evaluated using Cybex
      HUMAC/NORM (CSMI, 2004) brand isokinetic equipment, which measures torque produced against
      different speeds. With the isokinetic machine, the body extension-flexion movement will be
      measured with an angle of 60° and 90°. Similar to athletic performance tests, subjects will
      also complete a practice session on the machine prior to the test. Prior to core strength
      tests, subjects will warm up on the treadmill at low speeds for approximately 10 minutes for
      warm-up purposes. Trunk extension-flexion and measurements will be obtained following Smith
      et al.'s procedures.Verbal support will be provided by subjects to encourage maximum effort.
      Any report of symptoms of pain, shortness of breath, and/or dizziness will be recorded during
      the testing session.

      The range of motion will be adjusted from 10° extension to 45° flexion (ROM: 55°).

      Mutually concentric trunk flexion and extension will be evaluated at 60°/sec and 90°/sec
      angular velocities.

      During each trial, five repetitions of submaximal warm-ups will be performed before each test
      rate. A 5-second rest period will be allowed between the warm-up reps and the actual test
      session. For the test procedure, five maximum concentric contractions will be performed at an
      angular rate of 60°/sec. To test durability, 15 repetitions will be used at an angular rate
      of 90°/sec. The tests will begin in the full extension position. There will be a 20 second
      rest period between each angular speed test.

      They will be verbally encouraged during the test session to show maximum physical effort.

        -  Peak torque (Newton-meter (Nm)): It is the highest force value produced by the muscle.
           It can be determined at each repetition during the movement. Peak torque can be
           evaluated according to a certain time or angle (EHA) throughout the movement. Since peak
           torque is an absolute value, it may be insufficient in the evaluation alone and the same
           values may be interpreted differently from person to person.

        -  The ratio of peak torque to body weight (Newton.Meter/Kilogram): It is the ratio of the
           maximum torque produced to body weight. The heavier of two people with equal peak torque
           value will have a lower Peak torque/body weight ratio, while the one with the lower
           weight will have a higher value. This value will be evaluated according to sport
           activity, function, age and gender.

        -  Time to reach peak torque (seconds): It is the time for the muscle to reach maximum
           force. It indicates the ability of the muscles to produce maximum torque quickly.

        -  Peak torque reaching angle (degrees): It is the point where the peak torque is produced
           at the angle scanned throughout the movement.

      Vertical Jump Test: University of Toronto Belt Jump (Sports Books Publisher, Toronto,
      Ontario, Canada) consists of a rubber mat on which the participant stands and a tape feeder
      in the middle. The tape measure will be attached to a belt that is tied around the
      participant's waist. The bottom of the tape measure will pass through a feeder combined with
      the mat and the tape measure will be adjusted 0 cm before the jump. The tape measure will
      slide along the feeder until the participant reaches the top of the jump. After the jump, the
      height from the length of the tape pulled from the feeder will be recorded.

      They will perform a total of six jumps, with a maximum of three for warm-up before data
      collection. Specifically, subjects will do 2 sets of 10 repetitions each of the "arm swing",
      "lunge walking", "'walking knee lift" and "heel to toe lift" warm-ups before the test.

      Before each jump, participants will be instructed to "stand upright" for 3 seconds on the
      corresponding measuring device, which includes standing completely upright with their
      shoulders back and arms at their sides to standardize the starting position. At the end of
      this period, participants will be reminded to jump to the maximum level before being
      instructed to "jump". At the end of this period, participants will be reminded to jump to the
      maximum level before being instructed to "jump". They will then perform a maximum
      counter-motion jump (CMJ) with arm swing. If a participant jumps forward from the landing
      area, the jump will be repeated.

      Exercise Training After the exercises are fully taught to the athletes, the core training
      program will be applied on 3 non-consecutive days of the week, accompanied by a
      physiotherapist or athletic trainer, and the warm-up program will be applied before all
      trainings of the team, except before the match. In the 1st group training program, progress
      will be made in the exercises in the 2,5, v 8th weeks. The exercises selected for the core
      exercise program will be performed by creating stations from easy to difficult, with the help
      of the "Developing the core" book. As for the warm-up program, a combined protocol was
      created by considering the FIFA+11 and FIFA+11 S programs. The core program will take 20-25
      minutes, and the warm-up program will take an average of 20-25 minutes. The exercises consist
      of an average of 45 minutes. This warm-up program includes running exercises, strengthening
      exercises, balance and proprioception exercises, and plyometric exercises.

      In the shoulder External Rotation/Internal Rotation strengthening exercises that will be
      applied between 0-2 weeks, the arms will be adjacent to the trunk.2-5. arm 45 degrees in
      weeks, 5-8. In weeks, the arm is abducted 90 degrees. Low weights will be preferred in the
      exercises, and while the upper extremity exercises are planned to be performed 3 sets of
      10-15 repetitions, the progress will be made by increasing the resistance and weights. Lower
      extremity exercises including exercises such as running, balance and proprioception will be
      performed 2 times for 30 seconds.
