Abstract:   (140 Views)
Background: In runners with flat feet, biomechanical imbalance becomes more pronounced due to increased forces exerted on the body, which leads to higher energy expenditure. Therefore, this study aimed to determine the effect of orthotic insoles on energy expenditure in military runners with flat feet.
Methods: A treadmill and the Quark b2 system were used to measure oxygen consumption. Additionally, a pair of orthotic insoles tailored to the size of each participant’s feet was provided. Maximum heart rate, oxygen consumption, and maximum oxygen consumption (VO₂max) were measured and calculated for individuals with flat feet, both with and without orthotic insoles.
Results: After using the orthotic insoles, the mean oxygen consumption (VO₂) in milliliters per minute decreased from 4604.6 to 4588.3 (P<0.036). VO₂max, measured in milliliters per minute per kilogram of body weight, decreased from 65.2 to 64.6 (P<0.03). Maximum heart rate also decreased from 170.4 to 169.1 (P<0.032). All these reductions were statistically significant (P<0.05).
Conclusion: The use of orthotic insoles can help create more natural walking conditions for individuals with flat feet and reduce their energy expenditure.
