Which of the following is NOT a benefit of proper spinal alignment?

The choice indicating that increased metabolic rate is not a benefit of proper spinal alignment is accurate. While proper spinal alignment contributes to numerous benefits such as enhanced physical performance, reduced risk of injury, and improved posture, it does not have a direct link to increasing metabolic rate.

Proper spinal alignment primarily supports the body's functional mechanics, allowing for optimal movement, reducing strain on muscles and ligaments, and promoting a healthier overall posture. These factors can enhance physical performance by enabling more efficient movement and reducing the likelihood of injuries that may arise from misalignments. Additionally, good posture often results from proper spinal alignment, helping individuals present themselves more confidently and comfortably.

In contrast, metabolic rate, which refers to the speed at which the body converts food into energy, is influenced more by factors such as genetics, diet, and overall physical activity levels rather than spinal alignment. Thus, while alignment supports various physical and postural aspects, it does not directly affect metabolic processes.
