Abstract

|
Purpose: The purpose of this study was to determine whether ischemic preconditioning (IPC) improves lower limb isokinetic muscle function and blood lactate concentration.
Methods: In a randomized, crossover study, 10 men, college baseball players, performed knee extension and flexion using an isokinetic dynamometer, preceded by either IPC of the right lower limb (3 repetitions of 2 minutes occlusion and 5 minutes reperfusion at 180 mm Hg) or a control intervention (at 20 mm Hg). Blood lactate concentration was examined from rest to recovery after exercise.
Results: We found IPC possibly increased peak force and average power, but there is no significant difference. Also, blood lactate concentration was certainly lower at 3 minutes of recovery after IPC (p<0.05) but there is no interaction effect.
Conclusion: As a result, IPC does not have any positive effects on isokinetic muscle function and blood lactate concentration of college baseball players.
