孩子们和教练在滑板课程前进行拉伸。

of young skateboarders stretches on the ground of an outdoor skatepark, supervised by a coach in a white shirt and lanyard. One child wearing a helmet and pads stretches with assistance, while another youth in a backwards cap reaches for their foot. Skateboards are scattered around as others stand or sit in the background. The atmosphere is focused yet casual, capturing a shared moment of preparation and teamwork. The image emphasizes health, safety, and coaching in youth action sports environments.
