简要总结
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.
详细描述
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

研究组 & 干预措施
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.
干预措施: Ballistic Stretching Exercise (Other)
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.
干预措施: Extender Exercise (Other)
Kinesiotaping
Kinesio taping will be applied to the hamstring muscle in the direction of inhibition with a Y-shaped and 25% tension force.
干预措施: Kinesiotaping (Other)
结局指标
主要结局
Frequency of Biceps Femoris Muscle
时间窗: change from baseline frequency at 12 weeks
The tones of muscle is described by frequency of muscle or oscillation frequency (Hz). It will be examined by the MyotonPro, Tallinn, Estonia.
Frequency of Semitendinosus Muscle
时间窗: change from baseline frequency at 12 weeks
The tones of muscle is described by frequency of muscle or oscillation frequency (Hz). It will be examined by the MyotonPro, Tallinn, Estonia.
Stiffness of Biceps Femoris Muscle
时间窗: change from baseline frequency at 12 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.
Stiffness of Semitendinosus Muscle
时间窗: change from baseline frequency at 12 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.
Numeric Pain Rating Scale (NPRS)
时间窗: change from baseline pain at the time of activity at 12 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").
次要结局
- Standing Long Jump Test (SLJT)(change from baseline performance level at 12 weeks)
- 2K-rowing test(change from baseline performance time at 12 weeks)
