Summary

The study aims to investigate acute effects of ballistic hamstring stretching, hamstring extender exercise, and kinesiotaping application on viscoelasticity of hamstrings and standing long jump performance on rowers.

Detailed description

The study aims to investigate acute effects of ballistic hamstring stretching, hamstring extender exercise, and kinesiotaping application on viscoelasticity of hamstrings and standing long jump performance on rowers. A total of 60 professional rowing athletes were included. Viscoelasticity of hamstrings were assessed by MyotonPRO, Tallinn, Estonia. Athletic performance was assessed by Standing Long Jump Test (SLJT). The athletes were randomly divided into Ballistic Hamstring Stretching Group (n= 20), Hamstring Extender Exercise Group (n= 20), and Kinesiotape Group (n= 20). For balistic hamstring stretching, athletes were asked to reach the floor in the BS group by leaning over in the standing posture without knee flexion. When they feel the tension in hamstring muscle groups, athletes were requested to make small rebounding motion at degrees between 3°-5° for half a minute. For hamstring extender exercise, athletes were asked to apply the exercise 12 repetitions and 3 sets. Kinesiotaping was applied on the hamstring muscle with Y shape and 25% tension force.

Interventions

Type	Name	Description
PROCEDURE	Ballistic Hamstring Stretching	Athletes were asked to reach the floor in the BS group by leaning over in the standing posture without knee flexion. When they feel the tension in hamstring muscle groups, athletes were requested to make small rebounding motion at degrees between 3°-5° for half a minute.
PROCEDURE	Hamstring Extender Exercise	Athletes were asked to applied 12 repetitions and 3 sets of hamstring extender exercise. Firstly athlete lies on his/her back. Then, athlete is asked to do 90 degrees of knee and hip flexion at the same time. Finally, the person is expected to perform slow repetitive knee extension to the point of maximal possible extension.
PROCEDURE	Kinesiotape	Kinesio tape is applied on the hamstring muscle with a Y shape and %25 tension force.
