Gastrointestinal Symptom Rating Scale (GSRS)

For HP3 Coached Athletes

Purpose:
The GSRS helps you and your coach/nutritionist monitor your gastrointestinal (GI) health during training and competition. It identifies potential issues caused by diet, hydration, or exercise stress, allowing for tailored solutions.

Takes approximately 3-5 minutes

The GSRS is a disease-specific instrument. The 15 items combine into five symptom clusters: Reflux, Abdominal pain, Indigestion, Diarrhoea and Constipation. The reliability and validity of the GSRS are well-documented, and norm values for a general population are available. The original questionnaire is an interview-based rating scale but has been modified to become a self administered questionnaire.

How to Complete the GSRS

1. When to Fill It Out:

• Complete the form weekly or after key training sessions (e.g., long runs, race simulations).

• Use the form during taper periods and after races to track symptom changes.

2. Instructions:

• Answer all 15 questions based on how you felt during the past 7 days.

• Rate each symptom on a scale of 1 to 7:

• 1 = No discomfort

• 7 = Severe discomfort

Tips for Athletes

• Be Honest: Even mild symptoms are important to note.

• Track Patterns: Use your scores to identify recurring issues (e.g., bloating after a specific meal).

• Note Other Factors: If you experience symptoms, consider what might have contributed (e.g., new foods, training intensity, dehydration).
