[Purpose] Square-stepping exercise is recommended for elderly people, as it has a positive effect on cognitive and physical functions; however, few studies have examined the exercise intensity of square-stepping exercise. Therefore, we aimed to examine the exercise intensity of square-stepping exercise in community-dwelling late elderly females. [Participants and Methods] Study 1: The participants, constituting 12 community-dwelling late elderly females (age: 78.7 ± 3.8 years), performed the three target step patterns. Exhaled gas, heart rate, and rating of perceived exertion using the Borg Scale were measured during square-stepping exercise. Study 2: Participants were 57 community-dwelling elderly females (81.2 ± 4.3 years old). The exercise intensity, heart rate, and rating of perceived exertion using the Borg Scale during square-stepping exercise were measured. [Results] Study 1: The average METs of the 3 target step patterns was 3.6 ± 0.7, and the %heart rate reserve and rating of perceived exertion were 54.3 ± 20.0% and 11.4 ± 1.9%, respectively. Study 2: The average METs during the square-stepping exercise program was 2.1 ± 0.2, and the %heart rate reserve and rating of perceived exertion were 19.6 ± 10.2% and 11.3 ± 1.4%, respectively. [Conclusion] Square-stepping exercise was confirmed to be a low to moderate intensity exercise program and is expected to improve health and physical fitness.
