The factor commonly limited in older adults that affects their movement is trunk extension. As individuals age, they often experience a decline in muscular strength and flexibility, particularly in the muscles responsible for extending the trunk. This can lead to postural changes, making it more difficult for older adults to perform daily activities that require bending back or standing tall. Trunk extension plays a crucial role in maintaining balance, stability, and the ability to engage in various physical activities.

While other factors like core strength, joint range of motion, and overall flexibility are also important and may decline with age, the specific impact of trunk extension on posture and functional movement in the aging population is particularly significant. Limited trunk extension can contribute to a stooped posture, which can further affect balance and increase the risk of falls. Therefore, it is essential to address trunk extension and its associated musculature in exercise programs for older adults to promote better movement and overall health.
