Adolescence Distance Runner 2D Running Kinematics: Normative Data

IRB Number: 2019-0677

Institutional Review Board, Hospital for Special Surgery

February 06, 2023

The safety of study participants is our top priority. The trial is approved and periodically reviewed by an Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.

Before enrolling in a clinical trial, the investigator will explain the purpose of the trial, its expected benefits, any possible risks or side effects, and what your role will be. This is the time to ask questions! If you want to join the trial, you must sign the informed consent documents. You can leave a clinical trial at any time without penalty.

Running injuries are common in adolescents and are often related to biomechanical issues, but few studies have investigated the biomechanics of running in adolescents. This study aims to establish average kinematic values in 50 healthy adolescent distance runners using a 2D video analysis technology called Dartfish. The study will be conducted at the HSS main campus until 50 subjects are enrolled.

This study requires young distance runners (14-18 years old) to complete a short questionnaire about their participation in sports. They will then run on a treadmill for up to 10 minutes after warming up. A camera will record the position and movement of their body while running. Then, researchers will analyze the video for kinematic measurements.

Participants’ kinematic analysis data can be shared with the participant and may be used to improve performance and decrease injury risk.

Inclusion/Exclusion Criteria

Participants must be healthy adolescents between the ages of 14 -18 that have run at least 5 miles per week for the last 3 months prior to participation in the study. Adolescents may not participate if they have a history of lower extremity deformity, surgery, or any chronic musculoskeletal or neuromuscular disease, injury within the last three months prior to participation in the study, or inability to fill out forms in English.
