About

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.

Full 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

Enrollment: 60 patients

Sex: Male

Ages: 14 to 18 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Being between ages 14 and 18 and male gender
• Having been rowing at an elite level for at least one year with a professional team
• Having pain 3/10 or higher on NPRS
• Participating to the study in a voluntary basis.

Exclusion criteria

• Having limitation in lower extremity range of motion that limits completion of interventions
• Having a musculoskeletal injury involving the lower extremity in the last 6 months.

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

60 participants in 3 patient groups

Ballistic Stretching Exercise

Active Comparator group

Description:

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.

Treatment:

Other: Ballistic Stretching Exercise

Extender Exercise

Active Comparator group

Description:

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.

Treatment:

Other: Extender Exercise

Kinesiotaping

Active Comparator group

Description:

Kinesio taping will be applied to the hamstring muscle in the direction of inhibition with a Y-shaped and 25% tension force.

Treatment:

Other: Kinesiotaping
