Wearing the wrong clothing during physical activity can negatively impact performance in several ways. Clothing that is too loose or tight can restrict movement and hinder flexibility, leading to decreased range of motion and agility. Clothing that is not breathable can cause overheating and excessive sweating, leading to discomfort and dehydration. Additionally, clothing that is not suited to the specific activity can pose safety risks, such as wearing non-supportive shoes for running or biking. Choosing appropriate clothing that is comfortable, well-fitted, and breathable can help individuals perform at their best and reduce the risk of injury.
