Brief Summary

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

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 Assessors
The investigator administering the treatment and the investigator performing the evaluations will be different. The evaluator will not know about the interventions that the participants received.

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.

Group Type ACTIVE_COMPARATOR

Ballistic Stretching Exercise

Intervention Type OTHER

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.

Group Type ACTIVE_COMPARATOR

Extender Exercise

Intervention Type OTHER

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.

Group Type ACTIVE_COMPARATOR

Kinesiotaping

Intervention Type OTHER

It will be applied 4 times a week for 6 weeks and before starting on-water training.
