- Brief Summary
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.
- Detailed Description
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

Group Intervention Description Kinesiotaping Kinesiotaping Kinesio taping will be applied to the hamstring muscle in the direction of inhibition with a Y-shaped and 25% tension force. Ballistic Stretching Exercise 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. Extender Exercise 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.
- Primary Outcome Measures
Name Time Method Decrement of Biceps Femoris Muscle change from baseline decrement at 6 weeks The elasticity of a muscle is described by a logarithmic reduction of tissue's normal amplitude. It is more related with the dissipation of mechanical energy that arises between the deformation of the tissue and its recovery. It is a biomechanical feature of tissue that is called as elasticity. It will be examined by the MyotonPro, Tallinn, Estonia.
Decrement of Semitendinosus Muscle change from baseline decrement at 6 weeks The elasticity of a muscle is described by a logarithmic reduction of tissue's normal amplitude. It is more related with the dissipation of mechanical energy that arises between the deformation of the tissue and its recovery. It is a biomechanical feature of tissue that is called as elasticity. It will be examined by the MyotonPro, Tallinn, Estonia.
Stiffness of Semitendinosus Muscle change from baseline stiffness at 6 weeks 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.
Frequency of Biceps Femoris Muscle change from baseline frequency at 6 weeks The tones of muscle is described by frequency of muscle or oscillation frequency (Hz). It will be examined by the MyotonPro, Tallinn, Estonia.

Numeric Pain Rating Scale (NPRS) change from baseline pain at the time of activity at 6 weeks 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").
- Secondary Outcome Measures
Name Time Method 2K-rowing test change from baseline performance time at 6 weeks It is an ergometer test that measures 2,000 meter rowing time as a gold standard.
Standing Long Jump Test (SLJT) change from baseline performance level at 6 weeks It is a horizontal jump test that measures anaerobic performance.
