The hamstrings fundamentally influence adaptability of the body, and diminished hamstring adaptability brings about diminishes in trunk dependability and money owed to inappropriate change of the gluteus Maximus and stomach muscles1,3.The hamstring muscles is a significant part in the presentation of day by day exercises like Dynamic Stretched development of the storage compartment, strolling, running, and bouncing , and it is a significant muscle associated with keeping up with equilibrium and stance in standing position4,5. Increased hamstring’s flexibility plays a contributing role in enhancing athletic overall performance6. Balanced muscle tissues maintains joint's range of movement, which improves the encircling muscle groups' blood supply and contractibility, decreases put on and tear on the articular systems encapsulating the joint, promotes recuperation of confused tissue, and assists in motor-mastering strategies to make sure extra powerful and accurate overall performance techniques7,8. Recently created strategies to build the adaptability of the hamstrings incorporate static extending, contract-loosen up extending, thermo-treatment, rub, and neurodynamics9,10. Neurodynamics is a manual technique for applying power to nerve structures through act and multi-joint development11,13. In light of the rule that the sensory system ought to be likewise extended and contracted appropriately to keep up with ordinary muscle pressure and guarantee scope of movement14,15. Previously, it has arisen as prominent that a pre-body heat-up before active work can without a moment's delay impact execution11. Generally, a pre-action heat-up has included low profundity cardio practicing and some state of extending, alongside static or dynamic stretching16. Warming up can likewise affect muscle strength and force, athletic execution, joint assortment of development17, muscle adaptability, and possibility of injury12,18. Moreover, the impact of a warm-up on physical issue decrease is uncertain19. In this manner, it's miles basic to place in power amazing procedures of warming as much as accomplish the most adequate results and to save you mishaps8,20.Dynamic stretching has been defined as a ‘‘managed movement thru the lively range of movement for every joint’’ there may be some proof to suggest that dynamic stretching enhances electricity, agility sprinting overall performance vertical leap height and electromyography pastime measured at some stage in an isometric maximal voluntary contraction19. Neurodynamic is known to be very effective technique in increasing flexibility of hamstring muscles and is thought to be useful way to reduce neural mechanosensitivity (the specific response to mechanical stimulation)21,22. In Neurodynamic techniques, neural structures slide respectively to the nearby structures. The method to apply force is by postural method and movement of multi joint with the objective to stretch and slide neurodynamic structures9,23. The literature describes four common strategies of assessing hamstring muscle period those consist of the knee extension angle take a look at, the sacral angle take a look at, the straight leg boost check, and the sit-and-reach take a look at.7,16.
Hamstring muscles flexibility is very important among football players. By giving lower extremity stretching’ and sciatic nerve gliding blood supply and contractibility of muscle improved. The rationale of current study is to compare the effects of sciatic nerve gliding and lower extremity stretching’s on hamstring flexibility among football players.
Objective
To compare the effects of sciatic nerve gliding and lower extremity stretching’s on hamstring flexibility among football players
Methodology
Study Design
Randomized clinical trial. Randomization was done by lottery method. The Non probability convenient sampling technique was used. The study was single blinded (Assessor blinded). The sample was calculated by epitool software. Sample size was (n1): 10 athletes (n2): 10 athletes
Total Sample Size
Both groups have 20 athletes. The data collection Tools was used Universal Goniometer, Knee extension test, Straight leg raise test.
Duration
This study was 10 months.
Setting
Data was collected from Pakistan Sports Board Coaching Center, Lahore.
Inclusion Criteria
was footballers male with 18 to 30 years and having hamstring tightness of one or both legs, unable to achieve more than 160o knee extension with hip at 90o flexion and can reach <70o hip flexion in SLR.
Exclusion Criteria
Athletes with prior history of injury in lumber area, level of activity low for last three days, any disorder of low back like disc slip or herniation etc. and with the history of lower limb fracture were excluded from study.
Data Collection Procedure and Treatment Approach
After taking consent, participants were randomly selected and assigned in two groups. A 5 minutes warm up and cool down session were given before and after the treatment respectively and it was same for both groups. Before starting the exercise participants was assessed by using goniometer by performing straight leg raise and active knee were performed for both pretreatment and post treatment evaluation. After noticing down the measurements participants were divided in to two group. First group was given Sciatic nerve gliding and its procedure was force was applied at the proximal end and then released distally which is done by applying force on the proximal and repeat the processing in reverse order. This process was applied for thirty seconds and six times on each leg for three minutes (360 seconds). Second group was given lower extremity dynamic stretching. It was applied on the ankle in downward direction by holding for 30 seconds and repeated five times for total three minutes (360 seconds).this was done on both legs .total Treatment was of 3 weeks with 2 sessions per week.
Results
Analysis was through SPSS version 21. Graph 1 showed that Mean age and SD of athletes was 21±1.809. Within group comparison was done between pre and post treatment values which showed mean and SD for SLR right leg (60±4.33),( 76±6.70)and for SLR left was(62±9.33),
(84±2.06) while mean ±SD for the knee extension test right were (54±12.12), (113±12.51) and for the knee extension test left were (50±15.45), (108±9.52) p<0.05 for all which is statically significant in table 1.

Discussion
Current Study showed that sciatic nerve gliding was more effective in improving hamstring flexibility. Similar study from previous literature found in 2020 conducted by Danguole Satkunskieneet et al showed that viscoelastic behavior of the sciatic nerve was affected by stretching technique whereas more increase in the extensibility of hamstrings was due to the results of neurodynamic technique as a consequent of increased length of connective tissues and decreased nerve tension. So conclusion was made that neuro dynamic technique gave better results in increasing the extensibility of hamstrings. Current study’s findings also showed that sciatic nerve stretching is more effective21.
In contrast to current study, In 2019 Chaitali Shah et al, conducted a research which concluded that sciatic nerve gliding technique is less effective than the stretching of hamstrings. While the study reported it as well that both the techniques i.e. sciatic nerve gliding and stretching of hamstring are effective in their own way. According to current study comparison of active stretching and sciatic nerve gliding, sciatic nerve gliding gave more effective results22.
The current study supports the findings of the study conducted by A Balci et al in the year 2020 on wrestlers, revealed that the flexibility of hamstrings is increased by neural sliding and neural stretching exercises of the sciatic nerve24.
AR Ahmed et al. 2016 in the study short term effects of neurodynamic stretching and static stretching techniques on hamstring muscle flexibility in healthy male subjects concluded that flexibility of hamstrings could be increased markedly by neurodnamic stretching technique as comparative to sciatic nerve stretching in males with hamstring tightness.Current study also showed similar results 25. In contrast to current study, In 201 Amit Kumar Singh et al conducted study that concluded that PNF stretching is found to be more effective in increasing flexibility of hamstrings than Neurodynamic sliding in students of college. While the current study concluded opposite findings that sciatic nerve gliding to be more effective in increasing hamstring flexibility26.
Conclusion
On the basis of result, it was concluded that sciatic nerve gliding gave more effective results than lower limb stretching in increasing hamstring flexibility among football players.
