INTRODUCTION

  • The aim of this training project is to allow the subject GG, 22 yo, 196cm, 76 kg, to restart his sport activity as amateur volleyball player
  • The athlete, affected by bilateral rotuleous tendinopathy, came to our centre in order to be treated.
  • Our intervention was based on physioterapic sessions, then, once the subject achieved a complete return to functionality, he started a strength conditioning training in November 2019, in order to increase his load capacity, needed for his full recovery.
  • The strength conditioning training was based on isometric exercises (ex. Spanish squat) during the pre-training phase, according to the program proposed by J. Cook, integrated with isoinertial training with Desmotec D.full, in order to improve the subject’s eccentric response which is fundamental in the jumps landing phase, an high impact and frequent situation while palying volleyball.

CONCLUSIONS

 

 

  • The results were excellent, the subject felt his post- training and post-game pain gradually diminishing. The pain was almost unbearable before the treatment.
  • No cases of Tendinean Algia after the Isoinertial
  • Feeble pain (2-3 on a 10 scale) during isotonic monopodalic exercises At the end of the treatment, an exercises program was provided to the athlete, based on 5 sessions per week, to perform before training.
  • We were not able to perform the final isometric tests because of the COVID-19 emergency.
