SUMMARY
Background. Although ischemic preconditioning (IPC) has been used to improve performance in different sports, no consensus about the effectiveness of IPC on performance of amateur soccer players is established.
Objective. To investigate the effects of IPC on functional and neuromuscular performance of lower limbs of male amateur soccer players.
Methods. Male amateur soccer players aged 18 to 35 will be randomly allocated to IPC or IPC sham group. IPC group will receive four cycles of five minutes of ischemia (total blood flow restriction pressure [BFRP] of the posterior tibial artery) alternated with five minutes of reperfusion (i.e., BFRP of 0 mmHg). IPC sham group will receive the same protocol but a minimum BFRP (10 mmHg). We will assess functional performance (shuttle run and side hop test), neuromuscular function of knee flexors and extensors (isometric peak torque and isokinetic performance at 60°/s and 240°/s), rate of force development, thigh circumference, and Feeling Scale.
Results. The results will indicate whether IPC improves functional and neuromuscular performance of amateur soccer players.
Conclusions. This study is a clinical trial protocol based on SPIRIT recommendations and aims to evaluate the neuromuscular and functional performance of amateur soccer players.
Study registration. The study was registered in the Brazilian Registry of Clinical Trials (Register Number: RBR-3djfww).
