Clinical Trial 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.

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

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.	change from baseline frequency at 6 weeks
Primary	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.	change from baseline frequency at 6 weeks
Primary	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.	change from baseline stiffness at 6 weeks
Primary	Stiffness of Semitendinosus 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.	change from baseline stiffness at 6 weeks
Primary	Decrement of Biceps Femoris Muscle	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.	change from baseline decrement at 6 weeks

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