The aim of this study is to determine the relationship between oxygenation of calf muscles and physical performance including balance, gait speed, and endurance in older adults by utilizing the NIRS device. The investigators want to determine the relationship between different types of tests and oxygenation for older adults with 4 levels of physical activity. This study will help towards identifying possible short and effective exercises for older adults with different activity levels.
