Brief Summary:
Millions of sport related concussions (SRC) occur yearly in the United States, and current diagnosis of concussion is based upon largely subjective clinical evaluations. The objective of this study is to determine whether urinary metabolites are significantly altered post SRC. Urine of 26 athletes will be analyzed pre-injury and after SRC by 1H NMR spectroscopy. Data will be analyzed using multivariate statistics, pairwise t-test, and metabolic pathway analysis. Variable Importance Analysis based on random Variable Combination (VIAVC) was used to select what features are present out of 224 features. Partial least squares discriminant analysis was performed leading to separation between pre-season and post-SRC groups. A Receiver Operator Curve (ROC) curve will be constructed to classify the features. Pathway topology analysis will also be completed to determine biological pathways are potentially affected following SRC.

Arm Intervention/treatment
Each participant will act as their own control. Pre-injury samples were collected.
Other: urine metabolomics
We aim to determine of a specific urine metabolomic biomarkers can diagnose concussion.

Active Comparator: Post-injury
Post-injury samples were collected at the same time and within 72 hours of injury.
Other: urine metabolomics
We aim to determine of a specific urine metabolomic biomarkers can diagnose concussion.

Primary Outcome Measures :
  1. Urine metabolite profile [ Time Frame: Samples were taken within 72 hours of injury ]
    224 urine metabolites were analyzed pre- and post sport related concussion to determine which metabolites were altered post injury.
