This is because playing basketball mainly depends on the movement of upper limbs, especially the flexible dribbling and shooting with shoulders and arms. Wearing a vest does not affect the activities of shoulders and arms. Wearing short sleeves may sometimes limit the flexibility of athletes' shoulders and arms and affect the accuracy of passing, dribbling and pitching. In addition, in basketball games, physical confrontation is frequent, sports efficiency is high, and athletes are prone to sweating. Wearing a vest is beneficial to sweat evaporation and is relatively comfortable. However, football mainly depends on kicking the ball, and there is little shoulder-arm activity, so athletes do not need to consider the factors that affect shoulder-arm activity in their clothing. Moreover, football matches are mostly played outdoors, which can protect the body from the cold in cold weather.
