The aim of this studyis to research the effectiveness of proprioceptive neuromuscular facilitation (PNF)stretching and dynamic stretching on the flexibility of hamstrings in footballplayers.
Many of the current studies on PNF stretching are studying the effectof PNF stretching on many other factors, not DH1 just flexibility on thehamstrings (Konrad et al, 2014; Cengiz, 2015; Mehta et al 2013). The study willbe conductedon footballers because hamstring injuries and flexibility is a large problem inthe sport DH2 (Crema, 2016) and thereis not enough research into the comparison between DS DH3 and PNF. The MOI DH4 of a hamstring tear isusually the rapid deceleration during (Croiser et al, 2008DH5 ), and during a football match, accelerationand therefore deceleration occurs very frequently. DH6 If the flexibility canbe increased, the point at which the hamstring is under too much tensionbecomes later through the range of motion and so the hamstring will not tear soquickly. VanDoormaal et al (2016) studied the effect of flexibility on prevention ofhamstring injuries and concluded that more research was needed to provide areliable result to the research questionDH7 .
Cayco et al (2016)suggests that insufficient flexibility of the hamstrings can lead to lowerback, hip, and lower limbs problem which then leads on to a larger populationthat could need the treatment that will be proven to be the best during thisstudyDH8 . We would DH9 also like to draw a conclusion to if the flexibility doesnot help prevention of injuries, then whyDH10 . Although the study is focused on footballers, the study could beused for the prevention of the same injury in other sports because of themechanics of the injury, hamstring tears and strains are the most common injuryin sport, especially running (Lempainen, L, 2007). DH11 This study could also lead on to further research inflexibility and prevention using these methods.
By studying which is the bestform of stretching between these two methods, we will be able to provide a morereliable way of treating any injuries that may occur. Like many other studies O’Sullivanet al (2009) researched the effect on dynamic stretching and static stretchingon both flexibility and performance, although their results showed that dynamicstretching was not as effective as static stretching at increasing flexibility,the comparison was static stretching, and not PNF which is where our study willlie. Thisis why we believe a study into the comparison between PNF and dynamic is neededDH12 . Behm et al (2016) suggested that there are few studiesthat made a comparison between dynamic and PNF, the one study that wasperformed was performed in 1985 which showed that PNF increased ROM more thanDS (Wallin et al, 1985). This study could lead on to other research in similarareas to help understand the mechanism of injury in this area.
The study willalso look to improve the professional skills of each therapist and thereforeimprove the ability to treat different injuries.DH13 DH1Suchas? DH2Thiscould be expanded on DH3Ensureyou provide the full term first with the abbreviation in brackets DH4Andhere DH5Incorrectplace for the citation DH6Thisdoesn’t make sense – needs to be more specific DH7Butwhat did the results sugest? DH8Again,this doesn’t make sense. DH9Incorrectperson DH10Doesthe title reflect this? DH11Mostcommon sporting injury? Or one of? I can see where you’re coming from with this beingtransferable to other sports due to deceleration of running but what about thekicking action? DH12Youhave slightly missed the point with the rationale for the study – you should bediscussing the possible benefits of both, what previous research has shown, thepotential mechanisms by which they are effective and then stating why you wantto compare them. What benefits may come as a result of this research i.
e. ifone is more effective at increasing hamstring length than the other the thissuggests it could be used in reducing hamstring strains because xxxx said thereis a specific link between the two. DH13Notthe aims – how will you aim to improve tretaments??
