What researchers measure

Primary outcomes

  1. 50 meter Swimming Test

    Done by stop watch, changes will be assessed accordingly: First week Pre test and post test in 6th week which will be last week of work

    Time frame: 6th week

  2. Core muscle strength test

    Determine by stop watch .Used for monitoring of core strength of athlete. There are 8 levels Level 1: plank position hold for 60sec, Level 2: right arm lift and hold for 15 sec, Level 3: left arm lift for 15 sec, Level 4: right leg lift for 15 sec, Level 5: left leg lift for 15 sec, Level 6: right arm and left leg lift from floor for 15 secs, Level 7: left arm and right leg lift from floor for 15 sec, Level 8: then again hold plank for 30 sec. If individual feel difficulty at some level then end the test, and record that level. Good = complete, Poor= unable to perform. Changes will be assessed accordingly: First week Pre test and post test in 6th week which will be last week of work

    Time frame: 6th week

  3. Stroke rate

    Firstly calculate time need to complete three 3 stroke cycles. Then evaluate stroke rate by using this formula. SR= 60 × 3/tSR (SR- Stroke Rate, tSR- time taken of 3 cycles) Changes will be assessed accordingly: First week Pre test and post test in 6th week which will be last week of work

    Time frame: 6th week

  4. Kicking

    Time need for 50 meter of kicking performance by the use of kickboard ,stop watch use. Changes will be assessed accordingly: First week Pre test and post test in 6th week which will be last week of work

    Time frame: 6th Week

  5. Manual muscle testing (mmt) grading scale 0-5

    Latissimus dorsi, Serratus anterior,Upper trapezius,Flexors of hip,Extensors of hip,Plantar flexors by grading 0=no contraction,1= flickering contraction,2=full range of motion eliminated gravity,3= full range of motion against gravity,4= full range of motion with minimal resistance,5= full range of motion against maximal resistance Changes will be assessed accordingly: First week Pre test and post test in 6th week which will be last week of work

    Time frame: 6th Week
