Abstract


ABSTRACT

Title- Pressure Performance Index (PPI) as a Modulating Factor of Shooting Performance among Marksmen: A Pilot Study.

Background- Shooting performance is enhanced by working upon specific muscle strength with their regular general conditioning and fitness training. The stronger the muscle structure is developed, the better the movement can be coordinated and positions held. So we aim to study the effect of neck muscle strengthening on Pressure Performance Index (PPI) on shooting performance among marksmen.

Method-This is a pilot study in which 33  male  as  well  as  female  Rifle  Shooters  within  20±5  years  of  age  with  2-3  years  of  experience  and  participating  in  state/district  level  tournaments  were  assigned  into  2  groups. 16 subjects were  assigned  in  the  experimental  group (Group A)  who  underwent  neck  muscle  strengthening along with their regular general conditioning and fitness program.  While  17 subjects were assigned  in  the  control  group (Group B), who  continued  to  practice  their  general  conditioning and  fitness  program, both  for  4  weeks.  Evaluation and assessment was done pre and post with Pressure Performance Index (PPI) for neck muscle strength and its effect was seen on Bull’s Eye Target score.

Result- The  result  obtained  was  significant  improvement  in PPI (p=<0.01) and thus its effect on the Bull’s Eye Target Score (p=0.01) in Group  A;  whereas in Group B, no significant  improvement  was seen in PPI (p=>0.10) and thus its effect on the Bull’s Eye Target score (p=>0.10).

Conclusion- Neck muscle strengthening regime  is  comparatively  more  effective  in  improving  shooting  performance  over  general  fitness  and  conditioning  regime.

 

Keywords- Bull’s Eye Target Test; Marksmen; Neck muscle strengthening; Pressure Performance Index (PPI); Shooting performance.
