The cross becomes wider during sports because physical activity increases blood flow to the muscles, causing them to swell and become larger temporarily. This swelling, known as muscle pump, can make the cross appear wider due to the increased size of the muscles. Additionally, the cross may also appear wider due to the stretching and contracting of muscles during exercise, giving the illusion of a broader cross. **

The back widens during sports due to the engagement of various muscle groups, such as the latissimus dorsi, trapezius, and erector spinae. These muscles are responsible for stabilizing the spine, supporting the shoulders, and facilitating movements like pulling, lifting, and twisting. As these muscles are activated and strengthened through sports activities, they can increase in size and contribute to a wider appearance of the back. Additionally, improved posture and overall muscle development from sports can also contribute to a broader back. **
