Comparing the hand grip power and creatine kinase levels of U-17 judo national team athletes before and after a 6-week strength training

Abstract

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.

Morning versus Evening Intake of Creatine in Elite Female Handball Players

“…Although performance increased in the above tests, no statistically significant differences were observed in the dynamometer test. These latter results are not in line with the published literature, given that various studies report an improvement in hand grip strength after Cr intake [ 30 ], which could be due to the type of sport, the time of the study, or the training program followed by our participants. Other studies, in turn, argue that grip strength is closely related to hand length [ 31 ], and given that this is not affected by Cr intake, this could explain why there is a discrepancy between our results and the existing literature.…”

The effect plyometric training with active-passive recovery for 8 weeks on performance physical abilities male judo athletes

“…This study conducted Çelik and Soyal [26] concluded that strength training carried out for six weeks caused significant handgrip strength and creatine kinase changes in judo athletes, and these changes came from duration scope, frequency, and severity training content. In addition, high-intensity judo training affects changes in heart rate, flexibility, and strength of the neck muscles, and adequate rest after exercise can help prevent injuries to judo athletes [11].…”

Effects of Strength Training on the Female Athlete’s Lower Extremity

“…This training improves the gymnast's landing stability and strengthens the psychological suggestion of the gymnast' s safe landing. 13 This has laid a solid physical and psychological foundation for improving its exceptional quality. At the same time, the exceptional strength training of the lower limbs consolidated the stable center of gravity of the body's core muscles.…”
