Abstract
The present study was aimed to determine the effect of cold-water immersion and (TDCS) during the recovery period on blood lactate changes in and subsequent performance of professional male swimmers. For this purpose, 20 male participated in this study in two days with an interval of 48 hours. The two-hundred meter breaststroke was performed every day and then the subjects participated in one of the protocols, an anodic stimulation (with intensity of 2 mA)or the artificially exposed to anodic stimulation on the first day, and on the second day they were experienced the cold water immersion (12° C).The subjects' blood lactate was measured. Finally, in order to measure the effect of the investigated methods on their performance, the 200-meter swim was repeated. To analyze the data dependent t-test and analysis of covariance, LSD follow-up, analysis of variance with repeated measures, were used. The results of this study indicated that swimming performance significantly improved only in the TDCS group, with a reduction in the record time (P = 0.001). Blood lactate showed a greater decrease in the cold water immersion group (P = 0.001)

Abstract
Introduction and Objective: Core stability and plyometric exercises are training methods that athletes use to improve their performance. The purpose of this study was exploring the effect of a period of six week plyometric and core stability exercise on some of physical fitness of boy's athlete. Methods: 36 male athletes who were male with 11-14 years old participated in the semi-experimental study. They randomly divided in three group that each group has 12 subjects (first group; core stability exercise, second group; plyometric exercise and third group; control). The performance tests (standing broad Jump, Vertical Jump, 9.1 m Sprint, Shuttle Run, Flexibility and seated medicine ball toss tests) applied a day before starting core stability and plyometric exercises. Then post-test applied. In order to analysis data, ANOVA test was used (p<0.05). Results: Both core stability and plyometric exercise group showed significance increase in performance tests (Standing Broad Jump, Vertical Jump, 9.1 m Sprint, Shuttle Run). Conclusion: Based on the findings, we recommend the core stability and plyometric exercises in order to improve some of physical fitness of athletes.
