  Background : The physical growth pattern is driven by the genetic, but under the influence of environmental factors such as exercise, there may be changes in growth patterns and chronological and biological age may not match. The aim of the present study was to determine the relationship between calendar age and biological age with strength, speed, agility and balance of Kyokushin karate boys in Rasht. Method: The present study was a correlational descriptive study. The population of this research was Kyokushin Karate boys aged 12-30 of from Rasht city, 55 of them were selected non – randomly and available as a sample. In order to measure the research variables, physical fitness tests (strength, speed, agility, power and balance) and body composition (BMI and body fat percentage) were used. Data were analyzed using Pearson's correlation coefficient and t-statistics to compare two correlation coefficients.Results: The results showed that there is a positive and significant relationship between chronological age and anaerobic power, hand strength, agility and static and dynamic balance(p< 0.05). Also, there is a positive and significant relationship between biological age and anaerobic power, hand strength, agility and dynamic balance(p< 0.05). Conclusion: With the increase in the chronological and biological age of karate practitioners, we saw an increase in power and strength; however, speed decreased, which was not far off as body size increased. Also, static balance was only associated with increasing chronological age, which probably indicates that the growth of the skeletal-muscular system during puberty exceeds motor and balance growth.

  Karate is considered as one of the most intense and challenging exercise due to its intensity and types of activities. In these activities, the body is inflicted by the number of injuries and its antioxidant capacity is disturbed. Therefore, the present study was aimed at assessing the responses of muscle damage markers, oxidative stress and plasma antioxidant enzymes to the simulated karate activities and supplementation of skullcap plant in the elite karate athletes. Twenty-four eligible elite karate athletes were randomly assigned to two groups, consisting of placebo-activity group (n=12) and skullcap-activity group (n=12). The considered activities were based on the World and European Karate Championships programs. First, blood samples were taken from research groups at the rest and then desired activities were performed by athletes. Next, the second blood sampling was taken, immediately after the activity and after that, the subjects in placebo and skullcap groups received 500 mg of placebo and skullcap capsules, respectively. The third blood samples were taken one hour after that and the fourth blood sampling was two hours after taking the supplement. Finally, plasma was removed from the blood and CK, LDH, MDA, GPx, TAC, and SOD indicators were measured.Results showed that the indicators of muscle damage and oxidative stress significantly increased (p < 0.001) immediately after simulated karate activates and decreased during the recovery period as well, while these changes were higher in supplement group (p < 0.05). Furthermore, antioxidant indicators have significantly increased after the activities, and this increase was at a higher level (p < 0.05) throughout the recovery period in the supplement group. The results of the present study showed that skullcap supplementation increased antioxidant indicators in the recovery period and decreased muscle and oxidative damage factors. Therefore, this plant can be recommended as a supplement to reduce damages, stress, and fatigue for karate athletes. Manuscript profile
