Effects of Strength Training on Freestyle Swimming Performance and Core Muscles Strength in Swimmers

Study Overview
=================
Brief Summary
-----------------
To compare the effectiveness performance and core muscles of Strength Training . strength in swimmers on freestyle swimming

Detailed Description
-----------------
There is lack of literature on strength training on freestyle swimming performance, core muscles strength in swimmers, kicking, and stroke rate. With the help of this study the swimming performance of individual s will improve.

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 | 
| 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 | 
| 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 | 
| 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 | 
| 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 |
