Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Ballistic Stretching Exercise
Athletes will be asked to reach the floor by leaning over in the standing posture without knee flexion. When they feel the tension in hamstring muscle groups, athletes will be requested to make small rebounding motion at degrees between 3°-5° for half a minute.
Ballistic Stretching Exercise
It will be applied 4 times a week for 6 weeks and before starting on-water training.
Extender Exercise
Athletes will lie on his back. Then, athletes will be asked to do 90 degrees of knee and hip flexion at the same time. Finally, the athletes is expected to perform slow repetitive knee extension to the point of maximal possible extension. According to Askling et al. and Aspetar protocol, it will be applied 12 repetitions and 3 sets.
Extender Exercise
It will be applied 4 times a week for 6 weeks and before starting on-water training.
Kinesiotaping
Kinesio taping will be applied to the hamstring muscle in the direction of inhibition with a Y-shaped and 25% tension force.
Kinesiotaping
It will be applied 4 times a week for 6 weeks and before starting on-water training.
