Morphological Changes in Quadriceps Muscles through 3-Week Combined Exercise using a Wearable Robot (EX1) in Young Adult

Objective: This study aims to analyze the effect of regular exercise through the combined walking-oriented aerobic and resistance exercises using EX1 in young adults. Design: Experimental one group pre and post testMethods: Participants comprised17 healthy young adults. All subjects performed a combined exercise program for 10 times using EX1. We measured quadriceps muscle thickness using ultrasound. Additionally, the hand grip strength test, and sit and reach test were performed before and after the exercise. Through paired t-test, we investigated whether there was a statistically significant difference in the measurement results after exercise program. Results: The rectus femoris muscle contraction ratio showed significant difference after exercise(P< 0.01). In the sit and reach test, flexibility showed significant difference after exercise(P< 0.01). The hand grip strength test also showed significant difference after exercise(P< 0.05). Conclusions: Healthy young adults can effectively perform various exercises commonly performed in daily life using EX1.
