Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	6th week
Primary	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	6th week
Primary	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	6th week
Primary	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	6th Week
Primary	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	6th Week
