Low back pain (LBP) is a prevalent issue among adolescent rowers, particularly males aged 14 to 16 years, with a high lifetime prevalence (94%) and point prevalence (65%). One of the mechanisms of lower back pain in rowing athletes is about the elasticity, stiffness and tone of the hamstring muscle. Current literature shows that stretching exercises, strengthening exercises and kinesiotaping affects hamstring viscoelasticity in various ways. Stretching exercises affect hamstring muscle tone and elasticity, strengthening exercises affect muscle stiffness and kinesiotaping affects muscle tone. While the effects of each of these interventions on viscoelastic properties individually are examined in the literature, studies comparing the effects of changes in viscoelastic properties caused by these interventions on low back pain, athletic disability index and athletic performance in rowers and their superiority among each other are lacking. The goal of this study is to change the viscoelasticity of the hamstring muscles and examine its effect on low back pain, disability index and athletic performance.
Volunteer male elite rowing athletes between the ages of 14 and 18 who score 3/10 or higher on the Numeric Pain Rating Scale at the time of activity will be included in the study. Signed voluntary consent will be obtained from participants and their legal representatives. Participants will be divided into three groups. Study groups will be as follows: a) ballistic hamstring stretching exercise b) hamstring extender exercise c) kinesiotaping

Frequency of Biceps Femoris Muscle
The tones of muscle is described by frequency of muscle or oscillation frequency (Hz). It will be examined by the MyotonPro, Tallinn, Estonia.
Time frame: change from baseline frequency at 12 weeks
Frequency of Semitendinosus Muscle
The tones of muscle is described by frequency of muscle or oscillation frequency (Hz). It will be examined by the MyotonPro, Tallinn, Estonia.
Time frame: change from baseline frequency at 12 weeks
Stiffness of Biceps Femoris Muscle
Stiffness of muscle is described by reaction to contraction or forces from outside of tissue that may cause the original form to deteriorate. It will be examined by the MyotonPro, Tallinn, Estonia.
Time frame: change from baseline frequency at 12 weeks

Numeric Pain Rating Scale (NPRS)
The NPRS is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable").
Time frame: change from baseline pain at the time of activity at 12 weeks
Standing Long Jump Test (SLJT)
It is a horizontal jump test that measures anaerobic performance.
Time frame: change from baseline performance level at 12 weeks
2K-rowing test
It is an ergometer test that measures 2,000 meter rowing time and power output as a gold standard.
Time frame: change from baseline performance time at 12 weeks
