Background: Different ethnic populations have normal values for reference. These values are vital to a precise interpretation of the 6MWT in clinical practice. Objective: To evaluate normal six-minute walk distance among young Saudi female population. Design: Cross sectional, Prospective. Setting: Academic set up. Patients and Methods: Cross sectional study conducted on female volunteers aged 18-30 years old. 6MWD was done in a 30 meters long corridor. Vital signs were measured before and after the test. MET was calculated from the distance walked. Main Outcome Measure(s): The primary outcome measure was the 6MWD. Results: Sixty-nine female volunteers participated in the study. Mean age was 23.00 (1.67) (years) and BMI was 22.67(4.10) kg/ m2. 6MWT mean distance covered was 403.43 (91.62) meters. The Metabolic Equivalent and Maximum Heart Rate (%mHR) achieved were 2.81(0.76) ml/kg/min and 50.41(6.7) %, respectively. Height was found to be positively correlated with 6MWD. The 6MWD was found to be in agreement with the reference equation for Saudi population (P <0.05). There is a significant difference in heart and respiratory rates, p<0.000, CI {-14.16(-4.54)}, {-5.45(-2.63) respectively. Conclusion: Height was found to be positively correlated with 6MWD. A large multicenter study is required to confirm the present data and to include a larger age scale.
