Background and Study Aim. The aim of this study is to compare the hand grip power and creatine kinase levels of male and female U-17 National Team Athletes before and after a 6-week strength training. Material and Methods. 15 female and 15 male U-17 athletes, who previously participated in international competitions, participated in our study. Besides the hand grip power and creatine kinase values, age, height, weight, and BMI (body mass index) values of the athletes were measured before and after the training. As the conclusion of the measurements, the mean age of the female participant athletes was determined as 14,93 years, their mean height was 158,3 cm, and the mean age of the male athletes was 15,73 years, while their mean height was 173,1 cm. Results: As the conclusion of the measurements, it was determined that there were statistically significant differences between the right hand grip power and left hand grip power parameters of male and female participant athletes measured before and after the 6-week training. Moreover, it was determined that there were statistically significant differences between the pre-test and post-test measurements of creatine kinase values of both male and female athletes (p> 0,05). Conclusions. As the conclusion, it was determined that the 6-week strength trainings applied to U-17 Judo National Team athletes caused significant changes in their hand grip power and creatine kinase values. The significant results obtained from our study are considered to be originated from the duration, scope, frequency, severity, and content of the training.

在进行6周的力量训练之前和之后比较U-17柔道国家队运动员的握力和肌酸激酶水平

背景和研究目标。这项研究的目的是比较6周力量训练前后U-17国家队男，女运动员的握力和肌酸激酶水平。材料与方法。之前参加过国际比赛的15位女性和15位男性的U-17运动员参加了我们的研究。除了手握力和肌酸激酶值外，还测量了运动员在训练前后的年龄，身高，体重和BMI（体重指数）值。作为测量的结论，确定女运动员的平均年龄为14,93岁，其平均身高为158,3 cm，男运动员的平均年龄为15,73岁，而其平均身高是173,1厘米。结果：作为测量的结论，确定在进行为期6周的训练之前和之后测量的男女参与者的右手握力和左手握力参数之间在统计学上有显着差异。此外，已确定在男性和女性运动员的肌酸激酶值的测试前和测试后测量之间存在统计学上的显着差异（p> 0.05）。结论。结论是，已确定对U-17柔道国家队运动员进行的为期6周的力量训练引起了其握力和肌酸激酶值的显着变化。从我们的研究中获得的重要结果被认为源自培训的持续时间，范围，频率，严重性和内容。
