Abstract
Aim: The purpose of this study was to determine the effect of ischemic preconditioning (IPC) in different time periods and limbs on lactate and rating the perceived exertion after strenuous exercise in judoists.
Method: In a randomized, crossover study, 13 male judo athletes were volunterd (more than 4 years of judo practice) took part in this study and performed two spacial judo fitness test (SJFT) with 90 second between trials in seven conditions: IPC in hands 5 and 20 min before exercise, IPC in legs 5 and 20 min before exercise, IPC in hands and legs 5 and 20 min before exercise and a sham intervention. IPC treatment consisted of 3, 5 min bouts of ischemia, followed each by 5 min of reperfusion. Rating the perceived exertion immediately after each test and lactate response were measureal after 5, 10 and 15 min of exercise. One-way repeated measures ANOVA and Bonferroni post-hoc test used.
Results: IPC in hands and legs 20 min before exercise decreased lactate accumulation in 10 and 15 min after exercise and rate of perceives exertion than sham condition.
Conclusion: If remote ischemic preconditioning applied in more muscular mass and 20 min before exercise, it improves lactate metabolism and rating of perceived exertion in judo athletes.
