Interpretation of Normative Score of Isokinetic Peak Torque of Hamstring and Quadriceps among Healthy Teenagers: A Protocol Study

Abstract

The isokinetic evaluation usually includes a comparison between the tested muscle length and its power.
Isokinetic testing serves to assess the peak torque of the quadriceps and hamstrings muscles by determining
the magnitude of generated torque. To the best of our knowledge till now the normality reference score of
peak torque among teenagers has not been established. The aim of the study is to evaluate the normative
reference score of isokinetic peak torque of hamstring and quadriceps muscles among healthy teenagers from
age group 13-17 years. This study involves enrolling 60 healthy participants from renowned secondary schools.
They will be brief on the research procedure by demonstration method. Participants will receive an assent
form, and parental informed consent will be secured. Anthropometric details will be taken into account prior
to the study. The research will focus on assessing quadriceps and hamstring peak torque using the BioMat Easy
isokinetic dynamometer®. The protocol will include calculation of peak torques of knee flexors and extensors.
The collected data will be analyzed using the Statistical Package of Social Science (SPSS, Version 20.0 Inc,
Chicago, IL). Normality of the collected data will be established by Kolmogorov-Smirnov test of normality. After
the completion of the study, reference values of hamstrings and quadriceps peak torque will be generated. This
will be beneficial as a diagnostic tool for the evaluation of sports injuries.
