Purpose: This study aimed to investigate the effects of Polking, a newly designed exercise for muscle strengthening, by observing the differences in muscle activation and plantar pressure between Polking and normal walking. Methods: A crossover study was conducted with 16 young adults, each performing normal walking and Polking along a 10-m path. Muscle activation by EMG of the eight upper and lower limb muscles and plantar pressure were measured before and after exercise and compared between the two walking types. Results: Except for the latissimus dorsi and tibialis anterior muscles, there was a significant increase (P < .01) in all muscles (i.e., anterior deltoid, biceps brachii, and triceps brachii for the upper extremity; gastrocnemius, vastus medialis, and adductor longus for the lower extremity). The average plantar pressure in g/cm² (P = .01) and delta CoF (P = .008) were higher during Polking than during normal walking. Conclusion: This study examined the full-body effects of Polking as a combined aerobic and anaerobic exercise and as a potential gait training method, showing notable increases in muscle activity in the upper and lower extremities.
