Assessing the Effectiveness of 10-Week Plyometric Training program in reducing dynamic risk factors for Patellar Tendinitis and on agility in Amateur Volleyball players : A comparative Quasi-experimental study

Title : Assessing the effectiveness of 10-week plyometric training program in reducing dynamic risk factor for patellar tendinitis and on agility in amateur volleyball players.

Volleyball involves repetitive high load jumping, which predisposes to patellar tendinitis while plyometric training may improve neuromuscular control , tendon load tolerance , jump performance and agility. There is limited evidence in amateur players especially on horizontal component.

the aim is to assess the effectiveness of a 10-week plyometric training on dynamic risk factor for patellar tendinitis and agility with objective to examine its impact on this risk factors, vertical jump hight, agility and to compare it with a lower limb strengthening program.

This study includes 44 amateur volleyball players aged 18 to 28 years, 1 year or more playing experience , regular practice ( 3 day/ week ) and willing to participate randomly allocated to standard training plus plyometric or standard training plus lower limb strengthening for 10-weeks. Exclusion criteria include existing patellar tendinitis , other chronic knee or musculoskeletal condition , poor schedule adherence or lack of consent.

Outcome measures includes biomechanical jump and landing analysis , signal leg decline squat with pain map for patellar tendinitis test, vertical jump ( vertec device ) and Sheppard test for volleyball specific agility.

by systematically comparing a 10 week plyometric training with a structured lower limb strengthening regimen in amateur volleyball players, the study is expected to generate clinically relevant evidence to guide coaches and physiotherapist in designing targeted , evidence based training strategies for injury prevention and performance optimisation in this under studied amateur population.
