عنوان انگلیسی The Effects of Daily Rhythms on Sports Functions and Physiological Variables of Immune Elite Swimmers
چکیده انگلیسی مقاله Introduction Daily rhythm as one of the biological rhythms with a period of about 24 hours on various body systems and physiological responses affect on them. Body temperature is a fundamental variable as one of the specifications used daily rhythms The main purpose of this study was evaluating the effect of circadian rhythms on exercise performing and physiological variants of security system in swimmers. Materials and Methods In one study, before and after the 12 men swimmers in the league, of Fars Province with an average age of 19.80+1.87 years, had been invited, and after explaining the situation and also completed a written consent form purposefully participated in the study. To measure the length of 400m and 50 meters breast stroke timer QQ model CR2032 (China) was used. The one-way analysis of variance (ANOVA) was used to this study. Result Results showed body temperature significantly increased from 6:00 to 18:00. Circadian rhythms significantly showed increase from 6 to 18 (P< 0.05); circadian rhythms significantly showed effect on performing record in 400m and 50m chest crawl swimming with decrease of influence in 18:00 rather than 6:00; also circadian rhythms significantly showed influence on Immunoglobulin A (IgA) in resting after 400m and after 50m swimming with increasing from morning to evening (P< 0.05(. But in Immunoglobulin G (IgG) not significant increase in 6:00 until 18:00 in three conditions. The effects of activities in IgA in 6:00 showed decrease after 400m swimming and increasing after 50m, and in 18:00 increasing after 400m and 50m, but not significant activity in 6:00 showed significantly increase effects in IgG after 400m and 50m swimming and not significant decrease in 18:00 the received (P>0.05(. Conclusion In this study, the body temperature exercise performance and IgA variant of security system, were influenced by circadian rhythms and kinds of practicing programs in 18:00 change IgG. So in the time of measuring body temperature exercise performance and variants of salivary of security system must be pied attention to influence of cicardian rhythms.
