Effects of 8-week ischemic preconditioning on swimming performance and power output in male 100-m freestyle swimmers: a randomized controlled trial.

ABSTRACT:

Purpose

This study aimed to investigate the long-term effects of an 8-week ischemic preconditioning (IPC) intervention on the athletic performance of male freestyle swimmers.

Methods

Eighteen male 100-m freestyle swimmers were randomly assigned to either the IPC group (n = 9) or the sham operation group (n = 9), with interventions administered three times per week over the course of 8 weeks. Athletic performance was evaluated through 100-m freestyle race tests and Wingate 30-s tests at baseline, at the 4th week, and at the 9th week. The data were analyzed via two-way repeated-measures ANOVA.

Results

After 8 weeks of intervention, the IPC group demonstrated significantly improved performance in the 100-m race compared with the placebo group (57.57 ± 2.30 vs. 59.90 ± 2.
