Muscle Activity During Running With New and Used Military Boots in Healthy and Pronated Feet Males

Abstract

Purpose: Footwear used by military individuals is essential to be scientifically evaluated during daily activities. This research aims to examine muscular activities while running with rubber’s new boots compared to used boots in men with healthy and pronated feet. Methods: Twenty-four men aged 20-25 years (12 men in the pronated group, and 12 men in the healthy group) participated in this research using the convenience sampling method. The subjects received two used and new boots. The boots were made of rubber. Electromyography (EMG) data of the dominant limb were collected while running at constant speed. Results: The main effect of “boot type” for semitendinosus muscle activity (P=0.018, η2=0.248) during the loading phase and tibialis anterior (P=0.041, η2=0.177) during mid-stance. Conclusion: Rubber boots mileage effect on selected muscle activities in men with and without pronated feet. The use of used rubber boots can increase running-related risk factors.
