Kürekçilerde hamstring kasinin viskoelastisitesi ve atletik performans: Balistik germenin, hamstring uzatma egzersizinin ve kinezyo bantlamanin etkileri

The study aims to investigate acute effects of ballistic hamstring stretching, hamstring extender exercise, and kinesiotaping application on mechanical properties of hamstring muscles and standing long jump performance on elite and sub-elite athletes. A total of 60 volunteer participants including 30 rowing athlete who are in Fenerbahçe Rowing Team and 30 rowing athletes who are in the Turkish Divers Club were included(60M; 15,08±0,787 years.) between January 2021-February 2021. Biomechanical parameters of hamstring muscles were assessed by MyotonPRO, Tallinn, Estonia. Athletic performance was assessed by Standing Long Jump Test (SLJT). The athletes were randomly divided into Ballistic Hamstring Stretching Group (n= 20), Hamstring Extender Exercise Group (n= 20), and Kinesiotape Group (n= 20). After applications, MyotonPRO and SLJT measurements were applied again. According to the results of study, There is an improvement in frequency of m. biceps femoris longus and frequency and stiffness of m. semitendinozus for BHSG, frequency of m. biceps femoris longus and relaxation time of m. semitendinozus for HEEG, and frequency and stiffness of m. biceps femoris longus and frequency, stiffness, relaxation time and creep of m. semitendinozus for KTG compared to before and after results. In addition, all groups have statistically significant improvement in athletic performance which is assessed by SLJT (p < 0.05). When comparing the three groups, there is only one statistically significant was found in frequency of m. biceps femoris longus (p < 0.05). This statistically significant difference was due to BHSG and HEEG, and there was a positivity towards BHSG. No difference was found between groups in terms of athletic performance which is assessed by SLJT. Ballistic Hamstring Stretching, Hamstring Extender Exercise, and Kinesio Taping applications can be used to improve the viscoelastic properties which are tones, stiffness, and flexibility of the hamstring muscles. There was no superiority between the three applications, but Ballistic hamstring stretching can be preferred to improve the frequency of the biceps femoris longus muscle. All three applications can be used to increase the athletes' athletic performance.
