Aim: Soccer due to its own functional characteristics rely more on some physiological factors than other sports. The purpose of this study was to assess the effect of resistance training with emphasis on eccentric phase with and without blood flow restriction and traditional resistance training on blood cortisol, endurance performance and anaerobic power in male soccer players. Method: Forty soccer players were selected and randomly divided into four groups include traditional strength training (n=10), eccentric resistance training with blood flow restriction (n=10), eccentric resistance training without blood flow restriction (n=10) and control (n=10). Blood sampling and tests were taken before and after the eight-week training period. A one-way repeated-measures and Bonferroni post-hoc test was used to compare the groups (P<0.05). Results: The results showed that the minimum, maximum, mean power and endurance performance in all three experimental groups had a significant increase after exercise (P<0.001). There was also a significant difference between the two groups experimental of resistance training eccentric with and without blood flow restriction at minimum power (p<0.05). There was a significant difference between resistance training eccentric with blood flow restriction and the traditional resistance training group at maximum and mean power. However, this effect was not significant for fatigue index (p=0.13) and cortisol hormone (p=0.33). Conclusion: Although the results related to the percentage of changes indicated an improvement in the anaerobic power and endurance function in the traditional exercise group compared to the other two training groups, traditional exercises could still be used.

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.
